The AdvanceTrac威 with RSC威
system includes a traction control
off selection in the message center.
The stability control light and stability control off light in the instrument
cluster will illuminate temporarily during start-up as part of a normal
system self-check, or during driving if a driving situation causes the
AdvanceTrac威 with RSC威 system to operate. If the stability control light
and stability control off light remain steadily illuminated, have the system
serviced by an authorized dealer immediately. The message center will
also indicate a failure with the brake system.
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 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.
• Engine power may be reduced.
Traction control system (TCS)
The traction control system 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
