are supplementary and should not
be relied upon too heavily when
operating the vehicle.

systems
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 brak-
ing 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
Enhanced VSC (Enhanced Vehi-
