2. Assemble the wheel wrench (H) and the two jack
handle extensions (I) as shown.
Be sure the hoist end of the extension connects to
the hoist shaft (E). The ribbed square end of the
extension is used to lower the spare tire.
3. Insert the hoist end
(open end) (F) of the
extension through
the hole (G) in the
rear bumper.
4. Turn the wheel wrench (H) 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 5-92.
5. Use the wheel wrench
hook that allows you to
pull the hoist cable
towards you to assist in
reaching the spare tire.
