during start-up as part of a normal system self-check. The stability
control light may illuminate (flash) during certain driving situations
which cause the AdvanceTrac
௡ system to operate. If the stability control
light illuminates steadily, have the system serviced by an authorized
dealer immediately. If equipped with a message center, the vehicle will
also indicate a failure with the AdvanceTrac
௡ system.
When AdvanceTrac
௡ performs a normal system self-check, some drivers
may notice a slight movement of the brake, and/or a rumble, grunting, or
grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTrac
௡ you may experience
the following:
• A slight deceleration of the vehicle
• The stability control light will flash.
• If your foot is on the brake pedal, a vibration in the pedal
• If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
• The brake pedal may feel stiffer than usual.
Traction control system (TCS)
Traction control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem; engine traction control and brake traction
control. Engine traction control works to limit drive-wheel spin by
momentarily reducing engine power. Brake traction control works to limit
wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction control is most active at low speeds.
During TCS events, the stability control light in the instrument cluster
will flash.
If TCS is activated excessively in a short period of time, the braking
portion of the system may become temporarily disabled to allow the
brakes to cool down. In this situation, TCS will use only engine power
reduction or transfer to help control the wheels from over-spinning.
When the brakes have cooled down, the system will regain all features.
Anti-lock braking and electronic stability control (ESC) will continue to
function during the cool-down period.
