Driving 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 this chapter) The AdvanceTrac system automatically turns on when the engine is started. However, the system does not function when the vehicle is traveling in R (Reverse) or, if equipped with four-wheel drive, in 4L (4X4 LOW). In R (Reverse) or in 4L (4X4 LOW), ABS and the traction enhancement feature will continue to function. The AdvanceTrac button allows the driver to control the availability of the AdvanceTrac system. AdvanceTrac system status is indicated by a warning indicator light with a "sliding car" icon in the instrument cluster that will flash when the system is activated and an indicator light in the control button that will illuminate when the system is turned off. In vehicles with a message center, the message "ADVANCETRAC OFF" will be displayed. If a failure is detected in the AdvanceTrac system, the warning indicator light in the instrument cluster will stay on.
