accident. When you change a wheel,
remove any rust or dirt from the places
where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use
a scraper or wire brush later, if needed,
to get all the rust or dirt off.

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly which has a secondary latch system.
It is designed to stop the spare tire from suddenly
falling off your vehicle. For the secondary latch
to work, the spare tire must be installed with
the valve stem pointing down. SeeStoring a Flat
or Spare Tire and Tools on page 522.
{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 next.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. If the cable
is not visible,
proceed to Step 6.
2. 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 wheel wrench
counterclockwise three or four turns.
518

4. Repeat this procedure at least two times.
If the spare tire lowers to the ground,
continue with Step 5 ofRemoving the
Spare Tire and Tools on page 507.
5. If the spare tire does not lower, turn the wheel
wrench counterclockwise until approximately
6 inches (15 cm) of cable is exposed.
6. Stand the wheel blocks on their shortest ends,
with the backs facing each other.
7. Place the bottom
edge of the jack (A)
on the wheel
blocks (B),
separating them so
that the jack is
balanced securely.8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the
wheel blocks) under the vehicle toward the
front of the rear bumper.

the center of the spare tire.10. Turn the wheel wrench clockwise to raise the
jack until it lifts the end tting.
11. Continue raising the jack until the spare tire
stops moving upward and is held rmly in
place so that the secondary latch has released
and the spare tire is balancing on the jack.
12. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack
until the spare tire slides off the jack or
is hanging by the cable.

rmly pulling the jack out from under the
spare tire with the other hand. If the spare tire
is hanging from the cable, insert the hoist
end of the extension, and wheel wrench into
the hoist shaft hole in the bumper and
turn the wheel wrench counterclockwise to
lower the spare tire the rest of the way.15. Tilt the tire retainer
at the end of the
cable and pull
it through the wheel
opening. Pull the
tire out from
under the vehicle.
