When AdvanceTrac威 with RSC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 with RSC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

single wheel spin by momentarily applying the brakes to the wheel that

is slipping. Traction control is most active at low speeds.

During either engine or brake 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.

Anti-lock braking, RSC威, and ESC are not affected by this condition and

will continue to function during the cool-down period.

The engine traction control and brake traction control system may be

deactivated in certain situations. But single wheel spin brake traction

control is always on. See the Switching off AdvanceTrac威 with RSC威

section following.
