The AdvanceTrac威 system includes a stability control light and a stability

control off light in the instrument cluster. Both the stability control light

and the stability control off light in the instrument cluster will illuminate

temporarily during start-up as part of a system self-check. The stability

control light may illuminate during certain driving situations which may

cause the AdvanceTrac威 system to operate. If the stability control light

illuminates steadily, have the system serviced by an authorized dealer

immediately.

When AdvanceTrac威 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威, you may experience

the following:

• A slight deceleration of the vehicle

• The stability control light will flash.

• A vibration in the pedal when your foot is on the brake 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 the 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.
