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 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. See the Switching off AdvanceTrac威

with RSC威 section following.

Electronic stability control (ESC)

Electronic stability control (ESC) may enhance your vehicle’s directional

stability during adverse maneuvers, for example when cornering severely

or avoiding objects in the roadway. ESC operates by applying brakes to

one or more of the wheels individually and, if necessary, reducing engine

power if the system detects that the vehicle is about to skid or slide

laterally.

During ESC events, the stability control light in the instrument cluster

will flash.

Certain adverse driving maneuvers may activate the ESC system, which

include but are not limited to:

• Taking a turn too fast

• Maneuvering quickly to avoid an accident, pedestrian or obstacle

• Driving over a patch of ice or other slippery surfaces

• Changing lanes on a snow-rutted road

• Entering a snow-free road from a snow-covered side street, or vice

versa

• Entering a paved road from a gravel road, or vice versa

• Cornering while towing a heavily loaded trailer (refer to Trailer

towing in the Tires, Wheels and Loading chapter).

The ESC system may be deactivated in certain situations. See the

Switching off AdvanceTrac威 with RSC威 section following.
