Follow this diagram to store the
underbody-mounted flat or spare tire.
1. Put the tire (E) on the ground at the rear of
the vehicle.
2. Remove the wheel cap, if the vehicle has one,
from the flat tire by tapping the backside of
the wheel cap with the wheel wrench (A).
Store in a safe location until the flat tire
is repaired. Once the tire is repaired, replace
the wheel cap.
A. Wheel Wrench
B. Hoist Shaft
C. Extension
D. Retainer
E. Spare or Flat Tire
(Valve Stem
Pointed Up)
3. Make sure the valve stem is pointed up and
to the rear. Then pull the retainer (D) through
the wheel opening.
4. Put the socket end of the extension (C)
through the hole just above the rear bumper at
a 45 degree downward angle. Connect the
socket end of the extension to the hoist
shaft (B).
5. 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.
