Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly equipped with a secondary latch system.
It's designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work, the
spare must be installed with the valve stem pointing
down. See ªStoring a Flat or Spare Tire, Jack and Toolsº
earlier in this section.
{CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly
and you and others could get hurt. Read and
follow the instructions listed below.To release the spare tire from the secondary latch
do the following:
1. Check under the vehicle to see if the cable end is
visible.
2. If the cable is not visible proceed to Step 6.
If it is visible, ®rst try to tighten the cable by turning
the wheel wrench clockwise until you hear two
clicks or feel it skip twice. You cannot overtighten
the cable.
3. Loosen the cable by turning the wrench
counterclockwise three or four turns.

counterclockwise. Keep lowering the jack until
the spare tire slides off the jack or is hanging by
the cable.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack. If the
spare tire does not slide off the jack completely,
make sure no one is behind you or on either
side of you as you pull the jack out from the
spare.
12. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while ®rmly pulling the jack out
from under the spare tire with the other hand.

Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or ¯at tire using
the hoist assembly until it has been replaced.
To continue changing the ¯at tire, see ªRemoving the
Flat Tire and Installing the Spare Tireº earlier in
this section.Spare Tire
Your vehicle, when new, had a fully in¯ated spare tire.
A spare tire may lose air over time, so check its
in¯ation pressure regularly. See
In¯ation Ð Tire
Pressure on page 5-67andLoading Your Vehicle on
page 4-48for information regarding proper tire in¯ation
and loading your vehicle. For instruction on how to
remove, install or store a spare tire, see
Changing a Flat
Tire on page 5-76.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly in¯ated. Have the damaged or ¯at road
tire repaired or replaced as soon as you can and
installed back onto your vehicle. This way, a spare tire
will be available in case you need it again.
If your vehicle has a spare tire that does not match your
vehicle's original road tires and wheels in size and
type, do not include the spare in the tire rotation.
