If You Are 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. If 1 J let your tires spin at high speed, they can explode, and you or others could be injured. And, the transaxle or other partsof the vehicle can overheat. That could cause an engine compartment fire or otherdamage. When you're stuck, spin the wheelsas little as possible. Don't spin the wheelsabove 35 mph (55 km/h) as shown on thespeedometer. Notice: Spinning your wheels can destroy partsof your vehicle as well as the tires. If you spin the wheels too fast while shifting your transaxle back and forth, you can destroy your transaxle. See "Rocking Your Vehicle To Get It Out."
