All-Wheel Drive (Option) If You're Stuck: In Sand, Mud, Ice or Snow In order to free your vehicle when it is stuck, you will need to spin the wheels, but you don't want to spin your wheels too fast. The method known as "rocking" can help you get out when you're stuck, but you must use caution. NOTICE: After installing a compact spare tire on a vehicle with all-wheel drive you will need to drive with light to moderate acceleration, for 10 seconds, in a straight line. This action will allow the vehicle to detect the compact spare tire and disable the all-wheel drive system. The AWD DISABLE message will come on indicating that the all-wheel drive system is off. You may detect a slight pull during this time, but this is normal. Damage to the all-wheel drive system will occur, if the vehicle is driven for an extended period with a compact spare tire installed and the all-wheel drive system in operation. See "All-Wheel Drive System" and "AWD Disable Warning Message" in the Index for more information. CAUTION: If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transaxle or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you're stuck, spin the wheels as little as possible. Don't spin the wheels above 35 mph (55 km/h) as shown on the speedometer. 5-41
