Driving 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. 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 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 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. If your vehicle seems to lose engine power while driving in deep sand or very deep snow, switching off the AdvanceTrac௢ 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 AdvanceTrac௢ performs a system self-check. During AdvanceTrac௢ operation you may experience the following: • A rumble or grinding noise • A slight deceleration of the vehicle • The AdvanceTrac௢ 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 AdvanceTrac௢ operation. Do not alter or modify your vehicle's suspension or steering; the resulting changes to the vehicle's handling can adversely affect the AdvanceTrac௢ system. Also, do not install a stereo loudspeaker near the rear console or either rear seat. The speaker vibrations can adversely affect the AdvanceTrac௢ sensors located in this area. 146
