Driving
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTrac system off by pressing the AdvanceTrac button.
This will allow your tires to "dig" for traction. Pressing the control once
will disable the AdvanceTrac stability enhancement and the engine
power reduction portion of the traction enhancement feature; the brake
portion of the traction enhancement feature will still function normally.
Pressing and holding the control for more than five seconds will disable
the AdvanceTrac stability enhancement and traction enhancement
feature. If the AdvanceTrac system is activated excessively for an
extended period of time, the brake portion of the system will shut down
to allow the brakes to cool down.
A limited AdvanceTrac 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.
AdvanceTrac 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 system helps the driver maintain steering control if
the vehicle begins to slide excessively left or right or spin out.
AdvanceTrac 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 AdvanceTrac 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 the Tires, Wheels and Loading chapter)
