௡ with RSC௡
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

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.

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
