Follow this diagram to store the underbody-mounted
spare tire.
1. Put the tire (E) on the ground at the rear of the
vehicle.
2. Remove the hubcap, if equipped, from the flat tire
by tapping the backside of the hubcap with the
wheel wrench (A). Store in a safe location until the
flat tire is repaired. Once the tire is repaired,
replace the hubcap.
3. Ensure the valve stem is pointed up and to the rear.
4. Pull the retainer (D) through the wheel.
5. Put the socket end of the extension (C), on a
45 degree angle downward, through the hole just
above the rear bumper and connected to the hoist
shaft (B).
A. Wheel Wrench
B. Hoist Shaft
C. Extension(s)
D. Retainer
E. Spare or Flat Tire
(Valve Stem
Pointed Up)
6. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench (A)
clockwise until you hear two clicks or feel it
skip twice. This indicates that the tire is secure and
the cable is tight. The spare tire hoist cannot be
overtightened.
7. Make sure the tire is stored securely. Push, pull (A),
and then try to turn (B) the tire. If the tire moves,
use the wheel wrench and socket end of the
extension to tighten the cable.
