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.

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 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.

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.
