and wheels installed. Driving with varying tire or wheel sizes may diminish any supple-
mental safety benefits of the VSM system.
Emergency Stop Signal (ESS)
The Emergency Stop Signal (ESS) alerts the driver behind by flashing the brake lights
when braking sharply and severely.
Operating condition(s)
僅 The vehicle suddenly stops. ABS is activated and the driving speed is over 55 km/h (34
mph). The hazard warning flasher automatically turns ON after blinking the brake lights
when the driving speed is under 40 km/h (25 mph), the ABS is deactivated, the sudden
braking is over. The hazard warning flasher turns OFF when the vehicle drives at a low
speed for a certain period of time.
NOTE
The Emergency Stop Signal (ESS) system will not activate, when the hazard warning flash-
ers are already on.
Brake Assist System (BAS)
The Brake Assistant System provides additional pressure when the brake pedal is momen-
tarily and strongly depressed in a situation sudden braking is required while driving.
The Brake Assistant System reduces the time for ABS (Anti-Lock Brake System) control to
enter and consequently reduces the braking distance, by providing additional pressure up
to the point of ABS intervention.
BAS operation
僅 When the vehicle speed is more than 30 km/h (20 mph) and the ABS control is not
entered. When the brake pedal is depressed strongly over a certain level. When the fric-
tion of the road surface is above a certain level.
BAS operation off
僅 The vehicle speed is below 10 km/h (6 mph). The brake pedal is depressed over a cer-
tain conditions. The friction of the road surface is below a certain level.
WARNING
The system may not operate depending on driver's driving habit, the degree to which the
brake pedal is depressed and the road surface condition.
Trailer Stability Assist (TSA) system
The Trailer Stability Assist (TSA) is operated as a vehicle stability control system. The TSA
is designed to stabilize the vehicle and trailer when the trailer sways or oscillates. There
are various factors that make the vehicle sway or oscillate.
