SAFETY PRECAUTIONS

II

To ensure safe and reliable operation, heed thefollowing safety precautions.

SAFE OPERATING PRACTICES

• Operation and maintenance of the vehiclemust be performed only by qualifiedpersonnel.

• Before driving, conduct a walk aroundinspection and check that all baggagecompartment doors and equipment accessdoors are securely shut.

• Make sure good visibility is maintained at alltimes. Keep windshields clean and free ofobstructions.

• Adjust the driver's seat so that all controlscan be reached easily.

• Always wear the safety belt when driving.

• Check the instrument panel frequently. Donot operate the vehicle when dials orindicators are not in their normal operatingcondition.

• Always pay attention to pedestrians passingin front and behind the vehicle. Always yieldto pedestrians at pedestrian walkways.

• Do not drive over obstacles on the road.Empty boxes, piles of leaves, and snowdriftscould conceal hidden dangers that coulddamage the vehicle suspension andunderbody.

• When turning or changing lanes, signal yourintention well in advance.

• When approaching to make a right turn,reduce the space between the vehicle andthe curb to make sure another vehiclecannot pass on the right. Since the vehiclemakes wide turns, allow enough space tomake safe turns.

• Switch from high beams to low beams whenmeeting or following other vehicles within500 feet (150 meters).

• Never leave the vehicle unattended with theengine running, or with the key in theignition. Turn off the engine, remove keysand apply the parking brake before leavingthe vehicle.

• Shut-off the engine before refueling, addingoil, performing maintenance or servicingtasks, unless stated otherwise.

• Fuel is highly flammable and explosive. Donot smoke when refueling. Keep away fromopen flames or sparks.

• Do not run the engine or HVAC system withaccess doors left open. Close compartmentdoors before operating any equipment.

• Do not remove the surge tank filler cap orthe cooling system pressure cap when theengine is hot. Let the engine cool downbefore removing filler caps.

• Do not attempt to push or pull-start a vehicleequipped with an automatic transmission.

• The service life of the vehicle depends onthe kind of maintenance it receives. Alwaysrecord any problems and report themimmediately to maintenance personnel.

DEFENSIVE DRIVING PRACTICES

• For city driving, allow a four to six secondtravel interval between your vehicle and thevehicle ahead. Increase this travel intervalto six to eight seconds for highway driving.Increase time interval for driving at night orin foul weather.

• Be prepared to stop when approaching anintersection. The stopping distance of thevehicle increases with the weight and speed.

• Establish eye-to-eye contact with otherdrivers and with pedestrians. Use, highbeam and low beam headlights, turn signalsand horn as needed.

• On highway, don't stare at the road ahead.Keep your eyes moving. Check mirrors anddashboard instruments frequently.

• To keep the vehicle from drifting acrosslanes during highway driving, always lookover the horizon on the road ahead.

• Adjust your speed to road conditions, trafficand visibility. Never exceed the postedspeed limits.

• If another vehicle is following close behind,reduce your speed to let the vehicle pass.

For additional information about safe operationand defensive driving practices, contact the localdepartment of motor vehicles authority.

KEYLESS ENTRY SYSTEM

By using this system, you can lock or unlock theentrance door and the baggage and servicecompartment doors. The keyboard is locatedbelow the entrance door handle. The mastercode in the microprocessor/relay module is pre-programmed by the manufacturer and cannot bedeleted. Moreover, you can program your ownentry code (e.g. a birthday or part of a socialsecurity number).

The master code is:

• Printed on the owner's wallet card;

• Printed on three decals, joined to theowner's wallet card.

• Printed on decal affixed to the keylesssystem microprocessor/relay module in thefront console;

When you use the keyless entry system, thekeyboard and step lights illuminate.

Do not push the buttons with a key, pencil or anyother hard or sharp object as the buttons couldbe damaged. Although each button is providedwith two digits separated by a vertical line, thereis only one contact per button. Press in thecenter of the button (between the two digits, onthe vertical line).

You must unlock the entrance door before youunlock any other baggage or servicecompartment door. If you let more than fiveseconds pass between the numbers you press,the system shuts down, and you have to enteryour code again. If the keyless entry system

LEVEL LOW SYSTEM (4, 5, 6)

LEVEL LOW SYSTEM CONTROLS 16094

During driving, the conventional air levelingsystem of the vehicle controls the height at threepoints: the front, the left rear and the right rear.Your vehicle is equipped with a suspensionsystem that consists of air springs (pressurized airbellows) located near each wheel. The amount ofair in each air spring (and thus the vehicle height)is controlled by automatic leveling valves thatoperate between the chassis and the axles of thevehicle.

The three leveling valves are located as follows:one at the front which controls the amount of air inboth front air springs, one at the left rear whichcontrols the left rear corner of the vehicle and oneat the right rear which controls the right rearcorner of the vehicle. During normal driving, thesevalves work automatically to maintain the chassisat the proper level above the axles, indifferent ofroad conditions or vehicle weight.

Note: Prévost Car vehicles are designed tooperate within specific weight load/ranges foreach axle(GAW) and for total vehicle weight(GVW). If the coach is heavier than the designlimits, Level Low System (LLS) componentsdamage and problems can occur.

When parked, and ONLY when parked, the levelof the vehicle can be manually adjusted within therange of travel of the air springs. Thus, if thevehicle is parked on uneven ground, the manualoverride leveling system can be used to level thechassis of the vehicle. With the ignition ON(engine running or not), turn the selector switchlocated on L.H. side control panel to the area ofthe vehicle requiring leveling, then press therocker switch accordingly (up or down) to inflateor deflate the selected set of air springs. The frontposition raises or lowers the front only and doesnot tilt the vehicle to its sides. Each rear position

raises or lowers its respective side, therefore, therear positions can be used to tilt the vehicle to oneside or the other, or they can be used to raise orlower the rear of the vehicle. When leveling, it isoften necessary to run the engine in order to getan adequate air supply.

Note: For maximum ease of ingress and egressas well as for maximum leveling range, lower thevehicle completely before leveling.

Note: It is always better to first level the rear ofthe vehicle (right to left) before raising or loweringthe front. After adjusting the rear, watch the levelindicator as you adjust the front. If the levelindicator shows that the vehicle is starting to tilt toeither side, stop adjusting the front as one of theair springs has come to the end of its travel range.

After manual leveling, turn OFF the engine. Thevehicle will stay in the leveled position (the air is"locked" in the air springs) as long as there are noair leaks. The vehicle will hold this position forseveral days. When engine is restarted, with thelevel selector switch in the OFF position and airpressure is adequate, the vehicle willautomatically level itself for driving conditions.

Warning: Do not drive the vehicle with the levellow selector switch in any position other thanOFF, as this may render the vehicle unsafe anduncontrollable. If this is the case, the Level Lowwarning telltale light in the dashboard will flash,reminding you that the selector is not in the OFFposition.

Note: If, for any reason, you wish to start theengine without moving the vehicle (to warm up theengine for instance) while keeping the vehicle inthe manually leveled position, place selectorswitch in any position except OFF. When ignitionswitch is turned to the OFF position, reset theselector switch to the OFF position.

FOOT-OPERATED CONTROLS

FOOT OPERATED CONTROLS 8118A

SERVICE BRAKES

The coach is equipped with a dual brakingsystem. The front brakes operate differently fromthe drive and tag axle brakes.

The dual braking system becomes a modulatedemergency system if a pressure drop occurs inthe rear brake system. Only the drive and tagaxles are equipped with parking brakes.

Service brakes are applied by depressing thebrake pedal. Braking increases with the amountof pressure applied to the foot pedal. Refer to"Other Features" chapter 4 under "Anti-lock

Braking System". When the brake pedal isdepressed, the brake lights turn ONautomatically.

For safe and effective braking, the air systempressure should reach at least 95 psi (655 kPa)in both the primary and secondary circuits.

A warning light and a buzzer will sound whenthe air pressure in either the primary orsecondary circuits drops below 70 psi (483 kPa).If this occurs, stop the coach, determine thecause of the pressure loss before proceeding.The brake pedal can be used in conjunction withthe transmission retarder. Refer toTransmission Output Retarder in this section.

Warning: Immediately report any brakesystem problem to the nearest Prévost orPrévost-authorized service center.

Warning: Do not "fan" or "pump" the brakepedal. This practice does not increase brakesystem effectiveness but rather reduces systemair pressure thereby causing reduced brakingeffectiveness.

Caution: "Riding" the brake by resting one'sfoot on the brake pedal when not braking cancause abnormally high brake temperature, candamage and cause premature wear of brakecomponents and reduce brake effectiveness.

ACCELERATOR PEDAL

Controls engine RPM as needed.

Note: The accelerator pedal will not operatewhen the front door is open.

Caution: Do not let the engine operate above2,450 RPM.

STEERING WHEEL ADJUSTMENT UNLOCKAIR VALVE

Push on the valve button with the left foot tounlock the steering wheel for tilt and telescopicadjustment.

Warning: Do not adjust the steering wheelwhile the vehicle is moving. Loss of control couldresult. Park the vehicle safely and apply parkingbrakes before adjusting the steering wheel.

AUTOMATIC TRANSMISSION

The operation and driving of this vehicle with anautomatic transmission is similar to that of an


3-21

automobile equipped with an automatictransmission.

The transmission is fully automatic: Properranges should be automatically selectedaccording to driving speeds to improve vehicleperformance and control. The speed ratio of thepower converter changes automatically asvehicle speed increases and direct-drive goes inand out as necessary, The speed ratio ismodulated by vehicle speed and acceleratorposition.

OPERATION

When a button is depressed, the correspondingletter or number is displayed indicating thetransmission is ready to operate in the selectedrange. When the electronic control systemdetects a serious problem in the transmission, abuzzing tone sounds for 5 seconds and the"CHECK TRANS" light on the dashboardilluminates to warn the driver that thetransmission is held in gear. If another isdepressed, the buzzing sound will continue untilthe original range is selected.

Note: As a light bulb and systems check, the"CHECK TRANS" light will illuminate when theignition switch is turned to ON. After about twoseconds the light will turn off. If the "CHECKTRANS" light remains on, the self-diagnosticsystem has detected a problem. If the problemdisappears, the light will go out, but a troublecode will remain stored in the ECU.

CONTROL PAD 07025

RANGE SELECTION – PUSH BUTTONSHIFTER

The push button shifter is used by the operatorto select Neutral (N), Reverse gear (R) or arange of forward gears (D). When a forwardgear range has been selected, the transmissionstarts in the lowest gear of the range and, asconditions permit, automatically upshifts until thehighest gear in the selected range is in use.

The digital display indicates the current gear oftransmission operation.

The function of each button is as follows:

• Select REVERSE gear by pressing "R".

• Select NEUTRAL by pressing "N". Note theraised edge around the "N" button so thedriver can orient his hand to the push buttonsby touch, without looking at the display. It isnot necessary to press this button prior tostarting the vehicle.

• Select DRIVE range by pressing "D". Thehighest forward gear will appear on the digitaldisplay and the transmission will shift to thestarting gear (not indicated on the digitaldisplay).

The " " and " " buttons are used to shift to ahigher or lower range selected. One presschanges gears by one range. If the button isheld down, the selection will scroll up or downuntil the button is released or until the highest orlowest possible gear is selected. Protectionmechanisms should inhibit selecting ranges thatare not appropriate or which may damagedriveline components.

FUNCTIONS OF THE MODE BUTTON

This button is used to invoke a special function(mode) that has been programmed into theECU. Both modes are equivalent from the firstto the fourth gear as the transmission upshifts ataround 2000 rpm.

the default "ECONOMY" mode allows forupshifts in fifth and sixth gear at around 1700rpm. This is a more efficient operation of thetransmission and thereby helps improve fueleconomy.

the "PERF" (performance) mode keeps upshiftsat 2000 rpm in fifth and sixth gears. This makesfor better performance than the economy modebut with a higher fuel consumption. It isrecommended this mode be selected while


3-22

driving up or down grades. The mode status willbe indicated on the digital display by a red LEDilluminating in the upper right corner of theMODE button when selected.

Oil Level Display Mode (optional)

Select oil level display mode by pressingsimultaneously on the " " and " " keys. A firstpress will indicate the transmission oil level aftera two-minute wait if the following conditions aremet:

• The vehicle is parked;

• The engine is in slow idle;

• The transmission has reached it’s normaloperating temperature;

• Transmission is in NEUTRAL;

• The optional sender unit is present andworking.

A code will be displayed one digit at a time:

O L - O K (oil level is correct);

L O - 0 1 (one quart low);

L O - 0 2 (two quarts low);

H I - 0 1 (one quart high);

H I - 0 2 (two quart high).

Note: If one or more conditions are not met, anerror code will be displayed:

O L - 5 0 (engine RPM too low);

O L - 5 9 (engine RPM too high);

O L - 6 5 (transmission not at NEUTRAL);

O L - 7 0 (sump oil temperature too low);

O L - 7 9 (sump oil temperature too high);

O L - 8 9 (output shaft rotation);

O L - 9 5 (sender unit defective).

To exit, press either D, R, or N button.

Diagnostic Display Mode

Pressing a second time (or a first time if oil leveloption not present) on the " " and " " keyssimultaneously will select the diagnostic displaymode. Refer to the "Technical Information"chapter for more information about the WTdiagnostic codes. To exit diagnostic display

mode, press either D, R, N button, or up anddown arrow keys at the same time.

Reverse (R)

Use this position to back-up the vehicle. Stopcompletely before shifting from forward toreverse or from reverse to forward. Touch thereverse (R) button, ‘’R’’ will be displayed and thereverse warning signal will be activated.

Neutral (N)

Use this position to start engine. Select neutral(N) when checking vehicle accessories and forextended periods of engine idle operation;parking brake must then be applied. The push-button shifter will automatically select neutralwhen the master switch is turned ON.

Note: The automatic transmission does nothave a park (P) position. Select neutral (N) andapply parking brake when the vehicle is leftunattended. A warning buzzer will sound if theengine is stopped and the parking brake has notbeen applied when foot pressure is removedfrom the brake pedal.

Warning: Always apply parking brake beforeleaving driver's seat.

Caution: Detroit Diesel engines should not beidled for extended periods at "slow" idle. Forextended idling, engine should run at "fast" idle.

Caution: Do not allow your vehicle to "coast" inneutral. This practice can result in transmissiondamage. Also, no engine braking is available inneutral.

Drive (D)

Use this position for all normal drivingconditions. After touching this pad, the vehiclewill start in first or second range and willautomatically upshift to a higher range as outputspeed increases. As the vehicle slows down,output speed decreases, the transmissionautomatically downshifts to the correct range. Ifa locked brake or a slick surface conditionshould occur, the ECU (Electronic Control Unit)will command converter operation (disconnectlockup) and inhibit downshifts for a period of timeor until normal wheel speed has been restored.

• First range (1):


3-23

Select this range when pulling through mud andsnow or when speed control is needed fordriving up steep grades. This range alsoprovides maximum engine braking power orretarder braking effect. In the lower ranges (1, 2,3 and 4), the transmission will not upshift abovethe highest gear selected unless engineoverspeed is detected.

Note: The transmission should normally beallowed to shift by itself, but manual shifting canbe done as described below.

• Second range (2)

Select this range when operating in heavy andcongested traffic. The transmission will start infirst and automatically upshift to second. Whenslowing, the transmission will automaticallydownshift to first range. Low ranges provideprogressively greater engine and retarder

braking power (the lower the range, the greaterthe engine and retarder braking effect).

• Third and fourth ranges (3 and 4)

Select these ranges when driving on moderategrades or when load and traffic conditions limitspeed.

Warning: Service brakes should not be usedto control the speed of vehicle on long, steepdescents. Instead, lower transmission rangesshould be used (in conjunction with outputretarder. Refer to "JACOBS Engine Brake" and"Transmission Retarder" headings in "TechnicalInformation" chapter 4 for details regarding bothsystems. This procedure keeps service brakescool and ready for emergency stopping.

Caution: When descending in lower ranges,care must be taken that engine speed does notexceed 2,450 rpm.

DETROIT DIESEL ELECTRONICCONTROL (DDEC) SYSTEM

DDEC is an advanced-technology electronic fuelinjection and control system for Detroit Dieselengines. As an integral part of the engine, theDDEC system provides a number ofperformance features and driver benefitsincluding improved fuel economy andperformance, reduced cold smoke and reducedmaintenance and repair costs. Theseadvantages are obtained by optimizing control ofthe critical engine functions which affect fueleconomy, engine reliability and the performanceof the injectors.

Its major components include an ElectronicControl Module (ECM), Electronic Unit Injectors(EUI), electronic throttle pedal and sensors. TheECM, which provides central processing andcontrol of the DDEC system, contains thefollowing:

• A microprocessor that continuously monitorsand analyzes the engine's performanceusing sensors during engine operation;

• Flash Random Access Memory (FRAM) thatstores ECM runtime software, whichcontains engine control instructions;

• Electrically Erasable, Programmable, Read-Only Memory (EEPROM) that providesinstructions for basic engine controlfunctions such as rated speed and power,engine governing, cold start logic andiagnostics and an engine protection system.

The Electronic Unit Injectors (EUI) operates on aprinciple similar to the mechanical unit injectorsystem. However, a solenoid operated controlvalve performs the injection timing and meteringfunctions which make injector timing muchsimpler and more precise.

DDEC provides the capability of quicklydiagnosing system malfunctions with a self-diagnostic system. The self-diagnostic systemmonitors all engine sensors and electroniccomponents and recognizes system faults andother engine-related problems by providing thetechnician with a diagnostic code. The DDECsystem will illuminate the dashboard CHECKENGINE and STOP ENGINE indicators whichare integral parts of the electronic diagnosticsystem. These lights are designed to indicate aproblem and transmit a coded signal to thetechnician to locate the defective component.To facilitate troubleshooting and obtain pertinentdata logged in the ECM (Electronic ControlModule) memory, a Diagnostic Data Reader(DDR) can be used (not supplied bymanufacturer). Plug the DDR into the receptacleon the upper left wall in the driver's footwell. Youcan also momentarily depress the STOPENGINE OVERRIDE switch on the L.H. lowercontrol panel (refer to "Controls & Instruments"chapter 3). Active and inactive codes will flashrespectively the STOP ENGINE and the CHECKENGINE indicators. Refer to "TechnicalInformation" chapter 8 under "DDEC IVDiagnostic Codes".

SHEMATIC DIAGRAM OF DDEC IV SYSTEM OEH3B402

DDEC IV ELECTRONIC CONTROLMODULE (ECM)

The simplest implementation of Data Hub doesnot require the addition of any hardware to thevehicle. Instead, basic Data Hub features builtinto the DDEC IV ECM are used. The ECMstores data such as miles, fuel used, idle time,PTO time, idle fuel, cruise time and cruise fuelon life-to-date, trip and daily basis. Dailyrecording is limited to a maximum of two days.

Selected parameters, such as oil pressure, aremeasured periodically under specifiedconditions. The measurements are analyzedover long time periods, which allows the systemto detect degradation in performance and warnthe user prior to component failure.

The average life span of up to ten componentsmay be specified in terms of miles, fuel used,time, engine RPM and engine hours. The ECM

tracks the specified factors and automaticallyalerts the user when the average life span of thecomponent has been attained. An event log isalso stored which indicates the vehicle status(e.g., off, idle, in motion) at 15 minute intervals.

Data stored in the DDEC IV ECM is extracted byconnecting a cable from a PC to the vehicle'sdiagnostic connector via an RP1202 adaptermodule. Data extraction takes about 20seconds.

MESSAGE CENTER DISPLAY (MCD)

MCD is a standard dashboard mounted graphicdevice that displays and records operational datatransmitted by the Detroit Diesel ElectronicControls (DDEC) and other electronicallycontrolled components on the SAE J1708/1587diagnostic data link.

OTHER FEATURES

WORLD TRANSMISSIONELECTRONIC CONTROL UNIT (ECU)

Works with the automatic transmission with thepush-button shift selector.

The World Transmission electronic controls hasfour major elements: The Electronic Control Unit(ECU), the Throttle Position Sensor (TPS),speed sensors and the transmission shiftselector control pad. Refer to "Controls &Instruments" chapter 3. These components worktogether to electronically control the functions ofthe transmission. The throttle sensor, speedsensors and shift selector transmit information tothe ECU. The ECU processes this informationand then sends signals to actuate specificsolenoids located on the control valve body inthe transmission. The action of the solenoidsaffects hydraulic circuits, which in turn control theupshifts, downshifts, and lock-up functions. Inaddition to controlling the operation of thetransmission, the WT electronic controls monitorthe system for abnormal conditions.

When one of these conditions is detected, theWT electronic control system is programmed toautomatically respond in a manner which is safefor the driver, the vehicle and the transmission.The WT electronic control system turns ON theCHECK TRANS light on the dashboard, whichserves as a fault indicator.

OTHER FEATURES

4-11

To enhance troubleshooting and to allowinterrogation of the ECU for valuable serviceinformation, the shift selector display on thetransmission control pad or an optionaldiagnostic tool can be used. For informationabout reading and interpreting diagnostic codes,refer to chapter 8, "Technical Information" under"World Transmission Diagnostic Codes".

TRANSMISSION RETARDER

The transmission retarder is an optional devicethat helps to reduce the speed of a vehicle. Itimproves vehicle control, increases driving safetyand permits more economical operation. Theretarder provides slowing power when it is mostneeded, such as when descending mountainroads, in stop-and-go traffic and on crowdedfreeways.

The retarder is provided with a switch on thedashboard and a lever on the steering column(refer to "Controls & Instruments" chapter 3).

Note: Extended use will raise the temperature ofthe transmission oil.

The retarder helps to reduce speed on gradeswithout using the vehicle's conventional servicebraking system. A retarder greatly increases theservice life of brake pads and discs, resulting inreduced brake maintenance costs.

Note: Each time the transmission retardersystem is in operation, the stoplightsautomatically illuminate.

Note: For vehicles equipped with the AntilockBraking System (ABS), as the wheels start tolock-up on slippery roads, the output retarderautomatically deactivates until the wheels rollfreely.

JACOBS ENGINE BRAKE

The JACOBS engine brake is an optional dieselengine retarder which uses engine compressionto aid in slowing and controlling the vehicle.When activated, (refer to "Controls &Instruments" chapter 3) the JACOBS brakealters the operation of the engine's exhaustvalves so that the engine works as a power-absorbing air compressor. This provides aretarding action to the wheels.

The engine brake is a vehicle-slowing device,not a vehicle-stopping device. It is not asubstitute for the service braking system. The

service brakes must be used to bring the vehicleto a complete stop.

Effectiveness of the engine brake system willvary according to the transmission range in use.The engine brake system is more effective inlower ranges and at higher engine RPM.

Warning: When descending significant grades,use the service brakes as little as possible. If theengine does not slow the vehicle to a safespeed, apply service brakes and shift to a lowerrange. Let the engine (and engine brake) slowthe vehicle. Keep brakes cool and ready foremergency stopping.

Note: Each time the engine brake system is inoperation, the stoplights automatically illuminate.

ANTI-LOCK BRAKING SYSTEM

The purpose of the Anti-lock Braking System(ABS) is to maintain vehicle stability and controlduring braking and to minimize the stoppingdistance in any road condition.

On slippery roads and more generally inemergency situations, over-braking frequentlyinduces wheel locking. Wheel locking greatlyincreases breaking distance on any roadsurface. Locked wheels also impede directionalcontrol and cause severe tire abrasion. An anti-lock braking system provides maximum brakingperformance while maintaining adequate controlon slippery roads.

The basis of ABS is constant monitoring ofwheel parameters during braking. Sensors oneach wheel of the front and drive axlesconstantly measure wheel speed during braking.This information is transmitted to a four-channelelectronic processor which senses when anywheel is about to lock. Modulating valves quicklyadjust brake pressure (up to 5 times everysecond) to prevent wheel lock. Each wheel istherefore controlled according to the availablegrip.

In this way, the vehicle is brought to a stop in theshortest possible time while remaining stableand under the driver's control.

Caution: Vehicles following ABS-equippedvehicles may not be able to brake as fast onslippery roads. Whenever possible, warn otherdrivers by depressing the brake pedal lightlyseveral times before braking.

OTHER FEATURES

4-12

RETRACTABLE TAG AXLE

The optional lifting of the tag axle is controlled bya valve located on the left lateral console. Thevalve can be switched to either the WHEELS UPor WHEELS DOWN position. The axle will beautomatically raised or lowered by air pressureaccording to the position of the valve switch.Refer to "Controls & Instruments" chapter 3.

The tag axle service brakes operate only whenthe tag axle is in the WHEELS DOWN position.Never lower the tag axle while the coach ismoving. When the tag axle is in the WHEELSUP position, the corresponding indicator light willilluminate and a beep will sound to alert thedriver of the tag axle's position. Lifting the tagaxle shortens the wheelbase and allows tighterturning. This is very useful in tight maneuveringareas like in a parking lot or when negotiating atight corner. Raising the tag axle transfers extraweight and additional traction to the drive wheelsproviding improved control on slippery roads.

Caution: In order to prevent damage to thesuspension, always raise the tag axle beforelifting the vehicle.

Caution: Never lower the tag axle while vehicleis moving.

VARIABLE ASSISTANCE STEERINGGEAR (OPTIONAL)

The steering effort is controlled automatically inrelation to vehicle speed. For more information,refer to Maintenance Manual Section 14:Steering.

COOLANT HEATER

This optional auxiliary heating system is used forpreheating and retaining the heat of water-cooled engines. It can be used before startup toease starting and to provide rapid operation ofthe interior heating system. It can also be usedwith the engine running to maintain coolant heatand interior temperature.

L.H. SIDE REAR SERVICE COMPARTMENT 22176

The heater operates independently of theengine. It is connected to the cooling system,heating circuits and to the vehicle fuel andelectrical system.

Warning: The coolant heating system uses thesame fuel as the engine. Do not operate in aclosed building or while refueling. Operate onlyin a well ventilated area.

SWITCHING THE HEATER ON

The pilot lamp illuminates when the heater isswitched ON. Combustion air flows in to flushout the combustion chamber and the watercirculation pump begins operating. The fuelmetering pump delivers fuel in precise amountsto the combustion chamber, where fuel andcombustion air form a combustible mixture whichis ignited by the glow plug.

Once the flame sensor has signaled to thecontrol unit that combustion has taken place, theglow plug and ignition coil are switched OFF.

Hot combustion gases are diverted at the end ofthe flame pipe and are then forced through theindirect heating surfaces of the heat exchanger.The heat exchanger transfers the heat to thecoolant water passing through the heatexchanger.

The heater is thermostatically controlled andoperates intermittently (i.e., the switched-on timeof the burner varies depending on the heatrequirement). The water temperature iscontrolled by the built-in water thermostat.

OTHER FEATURES

4-13

The water circulation pump remains in operationas long as the heater is operating, even duringthe regulated intervals and during the delayedcut-out of the heater. The pump can also beoperated independently of the heater by meansof an appropriate circuit. The heater can beswitched ON at any time (i.e., during the delayedcut-out period). Ignition takes place after thedelayed cut-out time expires.

SWITCHING THE HEATER OFF

The fuel supply is interrupted when the heater isswitched OFF. This causes the flame to go outand a delayed cut-out of 2.5 minutes begins.The circulating combustion air flushes theremaining combustion gases out of the chamberand cools off the heated parts on the exhaustside of the heat exchanger. The watercirculation pump continues to transfer the latentheat present in the heat exchanger, thuspreventing hot spots. Once the delayed cut-outtime expires, both the combustion air blower andthe water circulation pump switch OFFautomatically. A cut-out will automatically takeplace in case of heater failure. Refer to chapter8, "Technical Information" for more information.

COOLANT HEATER TIMER

The timer, located on L.H. lateral console is usedto program the starting and stopping time of thepreheating system. One of three possible timersmay be installed in your vehicle (refer to thethree following images). The system indicatorlight, located on the timer, illuminates when thesystem is functional.

Caution: The preheating system should notoperate for more than one hour before startingengine as this could discharge batteries.

Warning: Preheating system must not operatewhen vehicle is parked inside or during fuel fillstops.

Note: Preheating system uses the same fuel asthe engine.

HOSE INSPECTION

Inspect hoses regularly to ensure efficient,economical and safe operation of the engine andrelated equipment.

LUBRICATION

Grease all lubrication points during scheduledmaintenance. For heavy loads or extended use,lubricate more often. Refer to the MaintenanceManual, section 24 for information on lubrication.

PRE-STARTING INSPECTION

WITH ENGINE STOPPED:

Inspect hoses for leaks. Carefully inspect allfittings, clamps and ties. To prevent chafing,make sure hoses are not touching shafts,couplings, heated surfaces, sharp edges or otherparts. Since hose clamps and ties can vibrateloose or fail over time, inspect frequently andtighten or replace as necessary.

Check for loose nuts and bolts. Visually inspectsafety of compartment door latches. Testoperation of all exterior lights.


7-10

Caution: All hose clamps of 1 3/8" ID and over,used on the heating and cooling systems, are ofthe "Constant-torque" type. This type of clamp isdesigned to automatically adjust its diameter tocompensate for the normal expansion/contraction of a hose and metal connection thatoccurs during vehicle operation and shutdown. Atorque wrench should be used for properinstallation. The recommended torque is 90 to100 lbf·in. (10 to 11 N·m). The hose clamps willbreak if over-torqued and cause loss of coolant.Do not over-tighten, especially during coldweather when hose has contracted.

Leaks

Check for leaks under vehicle and incompartments.

Correct leaking hoses immediately. Failure tocorrect leaks can cause severe damage to theequipment, as well as increase operating costsdue to lost fluids. Treat fuel and oil leaks as animmediate fire hazard.

Warning: Fire hazard - personal injury andproperty damage may result from fire caused byleaking flammable fluids.

Hose Service Life

Hoses have a limited service life. Thoroughlyinspect hoses annually. Look for surfacedamage or indications of twisted, worn, crimped,cracked or leaking lines. Replace damagedhoses immediately.

Hoses should be replaced during major overhaulor after a maximum of five years service. Makesure replacement hoses match the originalequipment manufacturer's specifications.

Wheels And Tires

Check for loose wheel nuts. Both aluminumalloy and steel wheel nuts should be tightened to450 to 500 foot-pounds (610 to 680 N.m.)torque.

Tire Pressure

Keep the tires inflated to the recommendedinflation pressure to prolong tire life and forsafety.

Note: Recommended tire inflation pressures aregiven in the "Coach Final Record", placed in thetechnical publications package supplied with thevehicle. The cold tire inflation pressures are onthe Department of Transport certification platelocated on the L.H. console besides the driver’sseat.

Warning: Do not exceed maximum inflationpressure. Incorrect tire pressure increases tirewear and could lead to loss of driving controlbecause of reduced road handling. Check tirepressure regularly.

Doors

Close all exterior doors and windows. Check forgood tightness and fit.

Tools And Spares

Make sure the vehicle is equipped with a wheelnut wrench, door keys, spare belts, reflectorsand jack.

WITH ENGINE RUNNING:

Leaks

Walk around vehicle and listen for air leaks.

Turbocharger

Check for leaks and listen for unusual soundscoming from the turbocharger.

Automatic Transmission

Check automatic transmission oil level. Refer toheading "Automatic Transmission Oil Level" inthis chapter.

Gauges And Buzzers

Perform a telltale light test (see "Controls andInstruments" chapter). Make sure gauges are innormal operating condition. Indicator lights andbuzzers should all be OFF before driving.

Fuel Level

Make sure fuel level is sufficient.

Service Brakes

Check for correct pressure build-up. Pressureloss should not exceed 3 psi/minute (21kPa/minute) with engine stopped and withoutbrake applied. Perform a full brake application.Air loss should not exceed 7 psi/minute (48 kPa/minute).

Brake Test

Release parking and emergency brakes. Pumpservice brake pedal until air pressure drops to 65psi (448 kPa). Make sure the warning buzzeroperates and that the emergency brakes apply(the control valve knob lifts up). Allow airpressure to reach 95 psi (655 kPa) beforereleasing parking brake.

HEATING AND AIR CONDITIONING

Two air conditioning systems are available: thelarge capacity (central) A/C or the small capacityA/C (also known as driver’s air). Vehiclesequipped with the large capacity A/C benefitfrom a combination heating and cooling systemthat provides adequate capacity of conditionedand filtered air for all climactic conditions. Freshair is drawn into the system from the left(driver’s) side of the vehicle. Return air is takenfrom the middle of the vehicle. The driver’sheater and defogger are controlled separatelyfrom the central unit. An air mixture selectorenables air to be drawn into the system fromoutside the vehicle or recirculated. Driver’s airprovides cooling for the driver’s area only,maximizing available baggage space for otheruses.

DDEC IV DIAGNOSTIC CODES

To read the diagnostic codes, a Diagnostic DataReader should be plugged into the receptaclelocated on the lower side panel of the L.H.control panel. To read diagnostic codes as blinkcodes, momentarily depress the STOP ENGINEOVERRIDE switch while the ignition is ON, theengine is idling or shut off. Active codes will beflashed on the STOP ENGINE indicator lightfollowed by the inactive codes being flashed onthe CHECK ENGINE indicator light. The cycle isrepeated until the operator depresses the STOPENGINE OVERRIDE switch again. For example:code "43" consists of four flashes, followed by ashort pause, then another three flashes in quicksuccession. The following table is a list of theDDEC diagnostic codes.

WORLD TRANSMISSION (WT)DIAGNOSTIC CODES

The WT Diagnostic Code Memory List containsthe following headings: Code List Position, MainCode, Sub Code, Active indicator, Ignition CycleCounter and Event counter. Up to five (5) codescan be stored at the same time in this memory.

The last occurring codes are listed first.Accessing the code list position, main code, subcode and active indicator is done through theShift Selector Display or by using the Pro-LinkDiagnostic Tool. Access to the ignition cyclecounter and event counter can be done onlythrough the Pro-Link diagnostic tool. Thefollowing table is an example of the informationstored in memory.

"MODE ON"

Ignition cycle counter and eventcounter are not available onShift Selector Display

Note: All information stored in memory can beaccessed using the Pro-Link Diagnostic Tool.


8-8

Note: The diagnostic codes are stored in thememory queue in positions 1 through 5. Thelocation of a diagnostic code in the memoryqueue is identified by "d1" (diagnostic code #1)through "d5".

The following paragraphs define the different WTDiagnostic Code Memory List headings:

MAIN CODE

The general condition or area of fault detectedby the ECU.

SUB CODE

The specific area or condition under the MainCode in which the condition was detected.

ACTIVE INDICATOR

Illuminates when a fault condition is active (ShiftSelector will display MODE ON or the Pro-LinkDiagnostic Tool will display YES). The indicatorwill extinguish when the fault condition is gone.

IGNITION CYCLE COUNTER

Used to clear inactive diagnostic codes from thecode list in memory. The counter is incrementedeach time a normal ECU power-down occursfollowing the clearing of the active indicator. Adiagnostic code will be cleared from the listwhen the counter exceeds 25.

EVENT COUNTER

Used to record the number of times a diagnosticcode occurs prior to the incident being clearedfrom the code list. The last occurring code willbe stored in position "d1". If the most recentcode is already in the code list, that code will bemoved to position "d1". The Active Indicator willilluminate (Shift Selector will display MODE ONor the Diagnostic Tool will display YES), theIgnition Cycle Counter will be cleared and "1" willbe added to the Event Counter.

CLEARING THE ACTIVE INDICATOR ANDCODE RECORDS FROM THE CODE LIST INMEMORY

If the conditions causing a diagnostic code to beset are cleared, the Active Indicator can bemanually cleared by holding the MODE buttondown continuously for 3 seconds until a tone isheard from the shifter. To clear code records

from the list, hold the MODE button downcontinuously for ten seconds until a second tonesounds. All diagnostic records in the list that arenot active will then be cleared and the remainingrecords will then be moved up the list.

CODE READING AND CODE CLEARINGPROCEDURES

Diagnostic codes can be read and cleared bytwo methods: by using the Pro-Link 9000Diagnostic Tool plugged into the receptaclelocated in the driver's footwell or by using theShift Selector Display. The operation of the Pro-Link 9000 Diagnostic Tool is described in theuser's manual provided with the Tool. Thissection describes how to read and clear codesusing the Shift Selector Display.

The Diagnostic Display Mode can be entered forviewing codes at any speed. Codes can only becleared when the output speed = 0 and nooutput speed sensor failure is active.

READING CODES

Read codes as follows:

Enter the Diagnostic Display Mode by pressingboth the " " (up arrow) and " " (down arrow)push buttons at the same time, twice on thepush-button Shift Selector.

Note: To obtain the oil level, press the " " (uparrow) and " " (down arrow) push-buttons once,at the same time. Refer to "Oil Level Sensor(OLS) Codes" in this chapter.

Read the first code in the first of the five codepositions on the digital display of the ShiftSelector. For example, code "25 11" is stored inthe first position. The display will change everytwo seconds as follows:

• Code list position = "d1"

• Main code = "25"

• Sub code = "11"

Display will repeat steps a, b and c.

Press the MODE button momentarily to view thesecond position (d2) as described in step 2.

To view the third, fourth and fifth positions (d3,d4 and d5), momentarily press the MODE buttonas explained above.


8-9

Pressing the MODE button momentarily after thefifth position (d5) is displayed will return the codedisplay to the first position (d1).

Any code which is active will be indicated by theMODE ON indicator (Active Indicator) beingilluminated while in that code position. While inthe normal operating mode, the MODE ONindicator is illuminated to indicate theECONOMY mode operation. Refer to "Controls& Instruments" chapter under MODE.

Any code position in the list which does not havea diagnostic code logged will display "- -" forboth the Main and Sub Code displays. Allpositions after a code position without any codestored will also display "- -".

CLEARING CODES

Clearing of the Active Indicator is automaticallydone at ECU power-down for all codes exceptcode "69 34".

Some codes will clear the Active Indicatorautomatically when the condition causing thecode is no longer detected by the ECU. Refer tothe "Diagnostic Code List and Description" tablein this chapter.

Manual clearing is possible while in theDiagnostic Display Mode and after the conditioncausing the code is corrected (output speedmust be zero).

To clear all Active Indicators, hold down theMODE button continuously for 3 seconds untilthe Shift Selector tone sounds for 0.5 second.

Release the MODE button to return to normaloperating mode. If the condition causing thecode was not active at the time, the activeindicator will go out.

Note: If clearing a code while locked in a drive(D) or reverse (R) position (fail-to-range), thetransmission will still be in drive (D) or reverse(R) when the clearing procedure is completed.Neutral (N) must be manually selected.

EXITING THE DIAGNOSTIC DISPLAY MODE

The Diagnostic Display Mode can be exited byany of the following methods:

• Press the " " (up arrow) and " " (downarrow) push buttons at the same time on thepush-button Shift Selector.

• Press any range button, "D", "N" or "R" onthe push-button Shift Selector (the shift will

be commanded if it is not inhibited by anactive code).

• Do nothing and wait until the calibrated time(approximately 10 minutes) has passed.The system will automatically return to thenormal operating mode.

• Turn off power to the ECU (shut off theengine with the ignition key).

• After clearing the active indicator asdescribed in "Clearing Codes" section.

CLEARING RECORDS FROM THE CODE LISTIN MEMORY

If the Active Indicator has been successfullycleared manually and the MODE button is helddown continuously for 10 seconds while in thedisplay mode until a tone sounds, all diagnostic

records in the Code List that are not active willbe cleared and the remaining records will bemoved up the Code List.

DIAGNOSTIC CODE RESPONSE

The following responses are used in the"Diagnostic Code List and Description" table tocommand safe operation when diagnostic codesare set.

DNS - Do Not Shift Response

• Release lock-up clutch and inhibit lock-upoperation.

• Inhibit all shifts.

• Turn ON the CHECK TRANS light.

• Display the range attained.

• Ignore any range selection inputs from thepushbutton or lever Shift Selector.

DNA - Do Not Adapt Response

The ECU stops adaptive shift control while thecode is active.

SOL OFF - SOLenoid OFF Response

All solenoids are commanded OFF (turningsolenoids “A” and “B” off electrically cause themto be on hydraulically).


8-10

RPR - Return to Previous Range Response

When the speed sensor ratio or C3 pressureswitch test associated with a shift not successful,the ECU commands the same range ascommanded before the shift.

NNC - Neutral No Clutches Response

When certain speed sensor ratio or C3 pressureswitch tests are not successful, the ECUcommands a neutral condition with no clutchesapplied.
