I NOTICE: Spinning your wheels can destroy parts of your vehicle as wellas the tires. If you spin the wheels too fast while shifting your transaxle back and forth, you can destroy your transaxle. For information about using tire chainson your vehicle, see "Tire Chains" in the Index. Rocking Your Vehicle To Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. If your vehicle has traction control, you should turn your traction control system off. (See "Traction Control System" in the Index.) Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transaxle is in gear. If that doesn't get you out after a few tries, you may need to betowed out. If you do need to be towed out, see "Towing Your Vehicle" in the Index. 5-36
