Driving ADVANCETRACா WITH ROLL STABILITY CONTROLி (RSC) STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED) AdvanceTrac with RSC is an integrated system with four major components: Anti-lock Brake System (ABS), Traction Control, yaw control and a vehicle-roll motion sensor. It automatically utilizes these elements in varying combinations to help give the driver optimum control at all times. AdvanceTrac, which includes ABS, Traction Control and yaw control, helps your vehicle maintain traction when driving on slippery and/or hilly road surfaces, by detecting and controlling wheel spin. Excessive wheel spin is controlled by momentarily reducing engine power and rapidly applying the anti-lock brakes. The system is a driver aid which makes your vehicle easier to handle primarily on snow and ice-covered roads. RSC detects potential rollover type situations and quickly engages AdvanceTrac to help keep your tires firmly planted on the ground. If your vehicle should become stuck in deep snow or mud, try switching the AdvanceTrac with RSC system off by pressing the AdvanceTrac with RSC button located on the center console. This will allow your tires to "dig" for traction. If the AdvanceTrac with RSC system is activated and deactivated excessively in a short period of time, the brake portion of the system will shut down to allow the brakes to cool down. A limited AdvanceTrac with RSC function using only engine power reduction will still help control the wheels from over-spinning. When the brakes have cooled down, the system will again function normally. Anti-lock braking is not affected by this condition and will function normally during the cool-down period. The AdvanceTrac with RSC system enhances your vehicle's stability during maneuvers that require all available tire traction, like in wet/snowy/icy road conditions and/or when performing emergency maneuvers. In an emergency lane-change, the driver will experience better overall vehicle traction, and have better control of the vehicle. The AdvanceTrac with RSC system helps the driver maintain steering control if the vehicle begins to slide excessively left or right or spin out. AdvanceTrac with RSC will attempt to correct the sliding motion by applying brake force at individual tires and, if necessary, by reducing engine power. Driving conditions, which may activate the AdvanceTrac with RSC system, include: • Taking a turn too fast 249 2006 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus)
