IX. SAFETY

A. Active Safety

1. Brake control systems

a. Includes the full complement of Star Safety SystemTM features

1) Anti-lock Brake System (ABS): Helps prevent the wheels from locking when the brakes are applied firmly or when braking on a slippery surface

2) Traction Control (TRAC): Helps restrain the slippage of the drive wheels if the driver depresses the accelerator pedal excessively when starting off or accelerating on a slippery surface

3) Enhanced Vehicle Stability Control (VSC): Integrates engine output control and braking in coordination with steering control to ensure vehicle running, cornering and stopping performance for active safety

4) Brake Assist (BA): Provides an auxiliary brake force to assist a driver who cannot generate a large brake force during emergency braking, thus helping ensure the vehicle’s braking performance

5) Electronic Brake-force Distribution (EBD): Provides proper brake force distribution between the front and rear wheels based on driving conditions and, while cornering, controls the brake forces of the right and left wheels, helping maintain vehicle behavior

6) Smart Stop Technology (SST): Automatically reduces engine power when both pedals are pressed at the same time under certain conditions

a) Intervenes when the accelerator is depressed first and the brakes are applied firmly for longer than one-half second at speeds greater than five miles per hour

b) Doesn’t engage if the brake pedal is depressed before the accelerator pedal. This allows for vehicles starting on a steep hill to safely accelerate without rolling backward.

4. Standard Vehicle Proximity Notification System (VPNS)

a. The Vehicle Proximity Notification System (VPNS) helps notify pedestrians and bicycle riders of an approaching hybrid or electric vehicle, which typically only generate small sounds when driven

b. Will sound when the following conditions have been met

1) When the vehicle speed is above 0 mph and 15 mph or lower, or when the vehicle speed is 0 mph (stopped) and the brake pedal is not being pressed

2) When driving in EV Mode (= the engine is stopped)

3) When the shift position is in apposition other than “P”

c. The warning sound is a continuous polyphonic sound with the frequencies of 175 Hz (F) and 233 Hz (B flat) as the base frequencies/notes

1) Warning sound volume will increase the vehicle takes off (= vehicle take off movement is detected)

2) Warning sound volume will gradually increase through fade-in control

3) The sound increases in conjunction with vehicle speed (vehicle-speed-coupled control)
