driving on slippery and/or hilly road surfaces, by detecting and
controlling wheel spin. Excessive wheel spin is controlled by momentarily
reducing engine power and rapidly applying the anti-lock brakes. The
system is a driver aid which makes your vehicle easier to handle
primarily on snow and ice-covered roads.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTrac娂 with RSC system off by pressing the AdvanceTrac娂
with RSC button. This will allow your tires to “dig” for traction.
If the AdvanceTrac娂 with RSC system is activated and deactivated
excessively in a short period of time, the brake portion of the system will
shut down to allow the brakes to cool down. A limited AdvanceTrac娂
with RSC function using only engine power reduction will still help
control the wheels from over-spinning. When the brakes have cooled
down, the system will again function normally. Anti-lock braking is not
affected by this condition and will function normally during the
cool-down period.
The AdvanceTrac娂 with RSC system enhances your vehicle’s stability
during maneuvers that require all available tire traction, like in
wet/snowy/icy road conditions and/or when performing emergency
maneuvers. In an emergency lane-change, the driver will experience
better overall vehicle traction, and have better control of the vehicle.
The AdvanceTrac娂 with RSC system helps the driver maintain steering
control if the vehicle begins to slide excessively left or right or spin out.
AdvanceTrac娂 with RSC will attempt to correct the sliding motion by
applying brake force at individual tires and, if necessary, by reducing
engine power.
Driving conditions, which may activate the AdvanceTrac娂 with RSC
system, include:
• Taking a turn too fast
• Maneuvering quickly to avoid an accident, pedestrian or obstacle
• Hitting a patch of ice
• 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
• Hitting a curb while turning
• Driving on slick surfaces
• Cornering while towing a heavily loaded trailer (refer to Trailer
Towing in this chapter)
