Under this system, operating signal of shift lever is sent to hybrid vehicle control ECU to control hybrid motor, which changesshift ranges (R, N, D, B) electrically. When shift is put in P range, transmission control ECU receives operating signal fromhybrid vehicle control ECU and activates parking lock electrically.

1. Shift Range Change FunctionGear can be shifted to any shift range under condition when vehicle can drive except when reject function is in operation.When vehicle cannot drive with power SW at IG ON position, gear can be shifted only to P and N range.When vehicle cannot drive with power SW at ACC ON position, gear can be shifted only to P range.When power SW is at OFF position, gear cannot be shifted to any range.When main SW is operated at vehicle stop after starting hybrid system, gear is automatically changed to P range from anyother gear range and turns off power supply.

2. Reject FunctionChanging gear may not effect to change range under certain vehicle condition. Under such condition, warning buzzer ofcombination meter sounds to show the rejection and call for driver’s attention. Followings are shift operations and shift rangeconditions under which reject function is activated.∗ When gear is shifted from P range to other range without applying brake pedal, gear stays in P range.∗ Main SW cannot put gear in P range during driving but changes to N range.∗ Shift change to forward or backward during driving changes gear to N range.∗ When gear is changed from other range than D range to B range, gear is changed to N range automatically.

3. Combination Meter IndicationThe combination meter shows present shift range position. Other shift range positions than D or B range are not shown inlighting in the combination meter. This is to avoid unnecessary shifting operation to B range from other shift position except Drange.

4. Operation of Parking LockOperation signal from/to P range is sent from main SW or power SW to transmission control ECU through hybrid vehiclecontrol ECU. At that time the transmission control ECU operates P CON MTR relay, activates parking lock actuator withappropriate control of electric current, and lights up main SW when shift is at P range. If the system has abnormality onparking lock operation, it tells the system abnormality to the driver by lighting up master warning light on combination meter,displaying warning of the system abnormality on the multi–display, and blinking indicator light of main SW.

5. Operation at Electric Power OFFUnder electric power OFF, transmission control ECU receives signal from power source control ECU bymulti–communication, and sends shift range position information to hybrid vehicle control ECU. The hybrid vehicle controlECU sends signal to power source control ECU to tell whether it is right or wrong condition to turn off electric power.Accepted conditions for electric power OFF are as follows;∗ When hybrid vehicle control ECU is not sending request signal for parking lock release with shift range in P range position.∗ With shift range is at other range than P range, when hybrid vehicle control ECU is outputting signal that hybrid system is

not running or request signal for parking lock.∗ When there is abnormal motor’s not running condition with paring lock in operation, and hybrid system is not running and

parking brake is being applied.

Cruise Control

Cruise control is the speed control device, which can set desired speed by just operating the switch on the control panelwithout applying the accelerator pedal. The device can be used when driver would like to drive the vehicle at fixed speed.

Set ControlIf the cruise control switch is pushed to – SET side and hand is released from the switch during driving, (The available rangeof set speed: between 40 and 200 km/h) with the ON–OFF switch at ON (Power indicator comes on), the device storesvehicle speed at that time and controls it constantly at the set speed.

2. Set Speed ControlThe device compares the actual vehicle speed with the set speed, and controls the driving power of the motor and theengine by calculating the cruise control requirements to drive it constantly at the set speed.

3. Coast ControlIf the cruise control switch is kept pushed to the – SET side during driving in the cruise control mode, the device recognizesthe cruise control requirement is at zero and decelerates the vehicle speed. When hand is released from the cruise controlswitch, the device stores the vehicle speed while the vehicle speed is decelerating. From then on, vehicle speed iscontrolled to stay at that speed.Every time the switch is operated to – SET side momentarily (For about 0.5 seconds), the set speed is decreased by about1.6 km/h. However, in case of tap–down operation to make more than 5 km/h gap between the set speed and the actualvehicle speed, the device recalls the original set speed and controls it at the speed constantly.

4. Accel ControlIf the cruise control switch is kept pushed to the + RES side during driving in the cruise control mode, the device recognizesthe cruise control is on the acceleration side and accelerates the vehicle speed. When hand is released from the cruisecontrol switch, the device stores the vehicle speed at that time and controls it with the set speed constantly.Every time the switch is operated to + RES side momentarily (For about 0.5 seconds), the set speed is increased by about1.6 km/h. However, in case of tap–up operation to make more than 5 km/h gap between the set speed and the actual vehiclespeed, the device does not change the set speed. (Tap–up operation is not available.)

5. Resume ControlAfter the cruise control mode is cancelled by any one the cancel switches, the mode can be resumed and controlled at theset speed by operating the cruise control switch in the + RES direction providing that the vehicle speed has not droppedbelow the low speed limit [Approx. 40 km/h (25 mph)].The mode cannot be resumed if the vehicle speed once drops below the low speed limit, because the speed in the memoryis cleared.

6. Manual Cancel ControlIf any of the following signals is sent to the device while the vehicle is running in the cruise control, the cruise control iscancelled accordingly.∗ Stop light switch: ON (Depressing the brake pedal)∗ CANCEL switch of control switch: ON∗ ON–OFF switch: OFF

7. Auto Cancel Function

A) The set speed is cleared and the cruise control is canceled under the following conditions. The cruise main indicatorblinks until the main switch is turned OFF. The speed control is unavailable unless the main switch is turned ON again.

∗ When the stop light switch open or short–circuits.∗ When signal of sudden change in the vehicle speed is sent.

B) The set speed is cleared and the cruise control is canceled under the following conditions.∗ When there is malfunction of the stop light switch input circuit.∗ When the vehicle speed becomes lower than 40 km/h.∗ When the vehicle speed becomes lower than the speed that 16 km/h is subtracted from the set speed.

ABS, TRAC and VSC

1. ABS OperationIf the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of all the four wheel cylinders toautomatically avoid wheel locking and to ensure the directional and steering stability of the vehicle. Under the situation, theskid control ECU controls the solenoids in the actuators, using the signals from the sensors to move the brake fluid to thereservoir in order to release the braking pressure applied to the wheel cylinder. If the skid control ECU detects that the fluidpressure in the wheel cylinder is insufficient, the ECU controls the solenoids in the actuators to increase the brakingpressure.

2. Electronic Brake–Force DistributionSkid control ECU distributes appropriate brake–force to front and rear wheels (Control of brake–force distribution to front andrear wheels) corresponding to the vehicle driving conditions. It also makes effective use of rear wheel brake–force to matchloading condition and decelerating of the vehicle, resulting to reduce depressing of brake pedal and to ensure effectivebraking. In braking during making a turn, the ECU controls appropriate brake–force distribution to right and left wheels(Control of brake–force distribution to right and left wheels) to ensure stability and braking of the vehicle.

3. Brake Assist SystemSkid control ECU recognizes emergency braking from detecting applying speed of brake pedal and brake travel, andcontrols braking effectiveness to supply strong brake–force for the emergency braking.

4. VSC Operation (w/ VSC)Unexpected road conditions, emergency situation, and any other external factors may cause large under– or over–steeringof the vehicle. If they occur, the VSC system automatically controls the driving power and wheel brakes to reduce the under–or over–steering.To reduce large over–steering :If the VSC system determines that the over–steering is large, it activates the brakes for the outer turning wheels dependingon the degree of the over–steering to produce the moment toward the outside of the vehicle and reduce the over–steering.To reduce large under–steering :If the VSC system determines that the under–steering is large, it controls the driving power and activates the front wheelbrakes and rear inner side wheel brake to reduce the under–steering.If there is malfunction in the VSC system, the VSC indicator lights up to warn the driver.

5. Mutual System ControlDue to cooperative control with hybrid vehicle control ECU, skid control ECU controls hydraulic brake to collect muchelectrical energy by making the most use of regenerative brake.Skid control ECU also improves stability of the vehicle, performing cooperative control with power steering ECU to givesteering torque assistance, corresponding to driving conditions. (w/ VSC)

6. Electric Source Backup FunctionElectric charge is stored in brake control power supply. If voltage of vehicle electricity is declined, electric charge is releasedto cover electric supply to the system.

7. Fail Safe FunctionSkid control ECU monitors the system component parts electrically. In case there is abnormality in ECU, sensor signal andactuator, normal parts except parts with abnormality continue braking operation.Even in case braking is shut off due to malfunction of oil pressure source, braking is secured as master cylinder pressuremade by manpower works on wheel cylinder.In case only regenerative brake is not effective due to abnormality in communication with hybrid vehicle control ECU, controlwill be changed to have oil pressure brake generate all the braking force

SRS

NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructionsand the procedure, and precautions in the Repair Manual applicable for the model year.

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of informationwhen troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.

Work must be started more than 90 seconds after the power SW is pushed to the ”OFF” position and thenegative (–) terminal cable is disconnected from the battery.(The SRS is equipped with a back–up power source so that if work is started within 90 seconds fromdisconnecting the negative (–) terminal cable of the battery, the SRS may deploy.)

When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will becleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, powertelescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.However, it is not possible to make a record of these memory contents. So when the work is finished, it will benecessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoiderasing the memory in each system, never use a back–up power supply from outside the vehicle.

Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.

Do not expose the following parts directly to hot air or flame;

Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;

Never use SRS parts from another vehicle. When replacing parts, replace with new parts.

For the purpose of reuse, never disassemble and repair the following parts.

If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,replace with new one.

Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.

Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.

After work on the SRS is completed, check the SRS warning light.

If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the RepairManual.

∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the frontairbag sensor and deceleration sensor.– Driver Airbag– Front Passenger Airbag– Seat Belt Pretensioner

∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the sideairbag sensors.– Side Airbags– Curtain Shield Airbags

∗ The dual–stage SRS airbag system has been used for the driver and front passenger airbags. This system controls theoptimal airbag inflation by judging the extent of impact, seat position (driver seat), whether or not the seat belt is fastened(driver seat) and information from the front passenger occupant classification system.

∗ The front passenger occupant classification system judges whether the front passenger seat is occupied by an adult orchild (with child seat) or is unoccupied, according to the load applied to the front passenger seat and whether the seat beltis buckled. Based on the results, it restricts the deployment of the front passenger airbag, front passenger side airbag, andfront passenger seat belt pretensioner. In addition, the system informs the driver of the result of the judgment through theuse of the AIRBAG ON/OFF indicator lights.

∗ The airbag sensor assembly transmits a signal to the engine control module in order to stop the fuel pump when theairbag is deployed.

Air conditioning system operates when SW of multi–display or that of steering wheel is turned on. Turning on the SW sendssignal to A/C control assembly, running the air conditioning system.

1. Heater Blower OperationManual operationWhen the blower speed is set to a certain level using the blower control SW, the A/C control assembly sends the signals tothe blower control to control the blower motor speed.Auto operationWhen the auto SW is pushed, the A/C control assembly calculates necessary blower speed from setting of SWs and input ofthe sensors and sends the signals to the blower control to automatically control the blower motor speed.

2. Air Inlet Control Servo Motor ControlWhen the FRESH/RECIRC select SW is set to RECIRC, the air inlet control servo motor starts rotating to move the dampertoward the RECIRC side. The damper position is detected by the TERMINAL TPI of the A/C control assembly. The motorcontinuously rotates until the damper reaches its stop position. When the FRESH/RECIRC select SW is set to FRESH, theair inlet control servo motor starts rotating to move the damper toward the FRESH side. The damper position is detected bythe TERMINAL TPI of the A/C control assembly. The motor continuously rotates until the damper reaches its stop position.In auto mode, A/C control assembly controls the damper to move to the best position for the conditions without operating themode select SW.

3. Air Vent Mode Control Servo Motor ControlWhen the mode select SW is pushed, the ECU in the A/C control assembly activates the air vent mode control servo motor.The servo motor rotates to the position (FACE, BI–LEVEL, FOOT, FOOT/DEF, DEF) selected by using the mode select SW,and moves the damper.In auto mode, A/C control assembly controls the damper to move to the best position for the conditions without operating themode select SW.

4. Air Mix Control Servo Motor ControlBased on the set temperature by the temperature control SW, the ECU in the A/C control assembly sends a signal to the airmix control servo motor. This signal drives the motor to reach the temperature set by the temperature control SW, and movesthe film damper.

5. Humidity Sensor ControlA/C control assembly detects humidity in passenger room when A/C is turned on, with humidity detecting function of A/C room temp. sensor and controls to dehumidify for comfortable condition

6. Air Conditioning OperationA/C control assembly calculates target cooled temperature from information such as that of operating SWs, roomtemperature, humidity, ambient temperature and insolation to have target running speed of compressor assembly (Motor).The calculated control signal is sent to inverter to drive compressor assembly (Motor) (Electric motor) with control of inverter,resulting in operating A/C.
