Driving assist systems
When the VSC/TRAC are operating
If the vehicle is in danger of slip-
ping or the front wheels spin, the
indicator flashes to indicate that
VSC/TRAC have been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
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.
n ABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
n Brake Assist (if equipped)
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
n VSC (Vehicle Stability Control) (if equipped)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
n TRAC (Traction Control) (if equipped)
Maintains drive power and prevents the front wheels from spinning
when starting the vehicle or accelerating on slippery roads.
n EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
