Driving The Roll Stability Control button allows the driver to control the O F availability of the Roll Stability F Control system. The 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 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 "Roll Stability Control OFF" will be displayed. If a failure is detected in the 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 button once will disable the Roll Stability Control 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 button for more than five seconds will disable the Roll Stability Control stability enhancement and traction enhancement feature. If the vehicle is stuck in snow or mud or when driving in deep sand, switching off the Roll Stability Control system may be beneficial so the wheels are allowed to spin. If your vehicle seems to lose engine power while driving in deep sand or very deep snow, switching off the Roll Stability Control stability enhancement feature will restore full engine power and will enhance momentum through the obstacle. Some drivers may notice a slight movement of the brake pedal when the Roll Stability Control performs a system self-check. During Roll Stability Control operation you may experience the following: • A rumble or grinding noise • A slight deceleration of the vehicle • The Roll Stability Control indicator light will flash • If your foot is on the brake pedal, you will feel a vibration in the pedal. • If the driving condition is severe and your foot is not on the brake, the brake pedal will move to apply higher brake forces. You may also hear a whoosh of air from under the instrument panel during this severe condition. All these conditions are normal during Roll Stability Control operation. 243
