Driving Roll Stability Control System (if equipped) The Roll Stability Control system works in conjunction with the AdvanceTrac system to further enhance the vehicle's overall stability during aggressive maneuvers. The system helps maintain roll stability of the vehicle during aggressive maneuvers by applying brake force to one or more wheels. Driving conditions that may activate Roll Stability Control include: • Emergency lane-change • Taking a turn too fast • Quick maneuvering to avoid an accident, pedestrian or obstacle • Hitting a curb while turning The AdvanceTrac /Roll Stability Control system automatically turns on when the engine is started. However, the system does not function when the vehicle is traveling in R (Reverse). In R (Reverse), ABS and the traction enhancement feature will continue to function. The AdvanceTrac /Roll Stability Control button allows the driver to control the availability of the AdvanceTrac /Roll Stability Control system. AdvanceTrac /Roll Stability Control 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 active 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 /Roll Stability Control system, the warning indicator light in the instrument cluster will stay on. If the warning indicator light in the instrument cluster remains on while the engine is running, have the system serviced immediately. Pressing the control once will disable the AdvanceTrac stability enhancement/Roll Stability Control 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/Roll Stability Control and traction enhancement feature. If the vehicle is stuck in snow or mud or when driving in deep sand, switching off the AdvanceTrac system may be beneficial so the wheels are allowed to spin.
