Driving Avoid excessive speed because vehicle momentum can work against you and cause the vehicle to become stuck to the point that assistance may be required from another vehicle. Remember, you may be able to back out the way you came if you proceed with caution. If your vehicle is equipped with AdvanceTrac௡ with RSC, press the AdvanceTrac௡ with RSC button (refer to AdvanceTrac௡ with Roll Stability Control (RSC) Stability Enhancement System in this chapter) while driving in deep sand if you experience excessive engine power reduction. Mud and water If you must drive through high water, drive slowly. Traction or brake capability may be limited. When driving through water, determine the depth; avoid water higher than the bottom of the hubs (if possible) and proceed slowly. If the ignition system gets wet, the vehicle may stall. Once through water, always try the brakes. Wet brakes do not stop the vehicle as effectively as dry brakes. Drying can be improved by moving your vehicle slowly while applying light pressure on the brake pedal. Be cautious of sudden changes in vehicle speed or direction when you are driving in mud. Even four-wheel drive vehicles can lose traction in slick mud. As when you are driving over sand, apply the accelerator slowly and avoid spinning your wheels. If the vehicle does slide, steer in the direction of the slide until you regain control of the vehicle. If the transmission, transfer case, front axle or rear axle are submerged in water, their fluids should be checked and changed, if necessary. Driving through deep water may damage the transmission. If the front or rear axle is submerged in water, the axle lubricant should be replaced. After driving through mud, clean off residue stuck to rotating driveshafts and tires. Excess mud stuck on tires and rotating driveshafts causes an imbalance that could damage drive components. 319 2010 Expedition (exd) Owners Guide (own2002), 1st Printing USA (fus)
