Driving 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௢/Roll Stabilty Control 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௢/Roll Stability Control 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௢/Roll Stability Control system. Also, do not install a stereo loudspeaker near the rear console or either rear seat. The speaker vibrations can adversely affect the AdvanceTrac௢/Roll Stability Control sensors located in this area. Note: Pressing the AdvanceTrac௢ button will disable AdvanceTrac௢ and Roll Stability Control. Aggressive driving in any road conditions can cause you to lose control of your vehicle increasing the risk of severe personal injury or property damage. The occurrence of a AdvanceTrac௢/Roll Stability Control event is an indication that at least some of the tires have exceeded their ability to grip the road; this may lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. If you experience a severe road event, SLOW DOWN. 215
