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.

Roll Stability Control™ (RSC威)

Roll Stability Control™ (RSC威) may help to maintain roll stability of the

vehicle during adverse maneuvers. RSC威 operates by detecting the

vehicle’s roll motion and the rate at which it changes and by applying the

brakes to one or more wheels individually.

During an event that activates the Roll Stability Control™ (RSC威)the

stability control light in the instrument cluster will flash.

Certain adverse driving maneuvers may activate the Roll Stability

Control™ system, which include:

• Emergency lane-change

• Taking a turn too fast

• Quick maneuvering to avoid an accident, pedestrian or obstacle

The Roll Stability Control™ system may be deactivated in certain

situations. See the Switching off AdvanceTrac威 with RSC威 section

following.
