Driver assist systems

To help enhance vehicle safety, the following systems operate automatically in
certain driving conditions.
■
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
pushed, when the system detects a panic stop situation.
■
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turn-
ing on slippery road surfaces.
■
TRAC (Traction Control)
Helps maintains drive power and prevents spinning the rear wheels
when starting the vehicle or accelerating on slippery roads.
When VSC or TRAC is operating
If the vehicle is in danger of slip-
ping or the rear wheels spin, the
slip indicator light flashes to indi-
cate that the systems have been
engaged.
A buzzer (intermittent) sounds
when VSC is operating.
