secondary latch is engaged causing the tire
not to lower. SeeSecondary Latch System on
page 5-105.5. Use the wheel wrench
hook which allows you
to pull the hoist
cable towards you to
assist in reaching
the spare tire.

Installing the Spare Tire
Use the following pictures and instructions to remove
the at tire and raise the vehicle.
The tools you’ll be using include the bottle jack (A), the
wheel blocks (B), the jack handle (C), the jack handle
extensions (D), and the wheel wrench (E).1. If your vehicle has
wheel nut caps, loosen
them by turning the
wheel wrench
counterclockwise.
If the vehicle has a center cap with wheel nut caps,
the wheel nut caps are designed to stay with the
center cap after they are loosened. Remove
the entire center cap.
5-97

4. Make sure the jack head is positioned so that the
rear axle is resting securely between the grooves
that are on the jack head. Turn the wheel
wrench clockwise to raise the vehicle. Raise the
vehicle far enough off the ground so there is enough
room for the spare tire to t under the wheel well.5. Remove all the wheel
nuts and take off the
at tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an 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 you need to, to
get all the rust or dirt off. Rear Position

10. Tighten the nuts rmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
When you reinstall the regular wheel and tire, you must
also reinstall either the center cap, or bolt-on hub
cap, depending on what your vehicle is equipped with.
For center caps, place the cap on the wheel and
tap it into place until it seats ush with the wheel. The
cap only goes on one way. Be sure to line up the tab on
the center cap with the indentation on the wheel. For
bolt-on hub caps, align the plastic nut caps with
the wheel nuts and then tighten by hand. Then use the
wheel wrench to tighten.
Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with 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 must be installed with the valve stem pointing
down. SeeStoring a Flat or Spare Tire and Tools on
page 5-109.
{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.

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 wrench
counterclockwise three or four turns.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 5-93.
5. Turn the 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.

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.
