Raise H. Hoist Arm 1. Put the tire on the ground at the rear of the vehicle, with the valve stem pointed down and to the rear. 2. Pull the retainer through the wheel. 3. Put the chisel end of the wheel wrench, on an angle, through the hole in the rear bumper and into the hoist shaft. 4. Raise the tire fully against the underside of the vehicle. Continue turning the wheel wrench until the tire is secure and the cable is tight. The spare tire hoist cannot be overtightened. CAUTION: Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place. NOTICE: An aluminum wheel with a flat tire should always be stored under the vehicle with the hoist. However, storing it that way for an extended period could damage the wheel. To avoid this, have the wheel repaired as soon as possible. 5-28
