For four-door utility models equipped with an underbody spare tire carrier, follow these instructions to restore a spare orflat tire: 1. Lay the tire on the ground at the rear of the vehicle. Position the tire so that the valve stem is pointed down and to the rear of the vehicle. If You're Stuck: In Sand, Mud, Ice or Snow What you don't want to do when your vehicle is stuck is 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. 2. Tilt the retainer downward and through the wheel opening. Make sure that the retainer is fully seated across the underside of the wheel. 3. Attach the ratchet, with the UP mark facing you, near the hook at the end of the jack handle. Insert the other end,on an angle, through the hole i n the rear bumper and into the hoist shaft. 4. Raise the tire fully against the underside of the vehicle. Continue turning the ratchet until there are c m m two "clicks" or "ratchets." The spare tire hoist cannot be over-tightened. 5. Grasp and push against the tire to be sure it is stored securely and does not move. If you let your tires spinat high speed, they can explode, andyou or others could be injured. And, the transmissionor other partsof the vehicle can overheat. That could cause engine an compartment fire or other damage. When you're stuck, spin the wheels little as possible. Don't as spin the wheels above35 mph (55 k m h ) as shown on the speedometer. 5-36
