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
Switching off AdvanceTrac威
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTrac威 system may be
beneficial because the wheels are allowed to spin. This will restore full
engine power and will enhance momentum through the obstacle.
To switch off the AdvanceTrac威 system, select traction control off
through the vehicle setting menu in the multi-function display. Full
features of the AdvanceTrac威 system can be restored by selecting TCS
again or by turning off and restarting the engine.
If you switch off the AdvanceTrac威 system, the traction control system
will be de-selected in the multi-function display and the stability control
off light will illuminate steadily. Selecting the AdvanceTrac威 system again
will turn off the stability control off light.
