2. Insert the hoist end (chiseled end) of the extension
tool (C) through the hole in the rear bumper and
into the funnel-shaped guide. The chiseled end of
the extension is used to lower the spare tire.
3. Turn the wheel wrench (D) counterclockwise to
lower the spare tire to the ground. Continue to
turn the wheel wrench until the spare tire can be
pulled out from under the vehicle.
If the spare tire does not lower to the ground,
the secondary latch is engaged causing the tire
not to lower. See Secondary Latch System
on page 5-81.
4. Tilt the retainer when
the tire has been
lowered, and slide it up
the cable so it can
be pulled up through
the wheel opening.
5. Put the spare tire near the flat tire.
