Driving assist systems

To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
ABS (Anti-lock Brake System)
■
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
Brake assist
■
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
VSC (Vehicle Stability Control)
■
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
TRAC (Traction Control)
■
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
EPS (Electric Power Steering)
■
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
Enhanced VSC (Enhanced Vehicle Stability Control)
■
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
