5. Turn the lug wrench clockwise to
raise the jack until it lifts the
secondary latch spring.
6. Keep raising the jack until the
spare tire stops moving upward
and is held firmly in place. This
lets you know that the secondary
latch has released and the spare
tire is balancing on the jack.
7. Lower the jack by turning the lug
wrench counterclockwise. Keep
lowering the jack until the spare
tire slides off the jack.
8. Disconnect the lug wrench from
the jack and carefully remove
the jack. Use one hand to push
against the spare tire while
firmly pulling the jack out from
under the spare tire with the
other hand.
9. Tilt the retainer and slip it
through the wheel opening
when the spare tire has been
completely lowered.
10. Turn the lug wrench clockwise
to raise the cable back up if the
cable is hanging.
Have the hoist shaft assembly
inspected as soon as you can. You
will not be able to store a spare tire
using the hoist assembly until it has
been repaired or replaced.
Full-Size Spare Tire
The vehicle, when new, had a
fully-inflated spare tire. A spare tire
may lose air over time, so check its
inflation pressure regularly. See Tire
Pressure on page 10‑51 and Vehicle
Load Limits on page 9‑27 for
information regarding proper tire
inflation and loading your vehicle.
For instruction on how to remove,
install or store a spare tire, see Tire
Changing (H3T) on page 10‑66 or
Tire Changing (H3) on page 10‑75.
