and the ratchet (E).
Your spare tire is stored underneath the rear of your
vehicle. You will use the wheel wrench (D) and the
ratchet (E) to lower the spare tire.
The ratchet has a DOWN side and an UP side.Attach the wheel wrench
and ratchet, with the
DOWN side facing you.
The wheel wrench

¯at chisel end.
Put the ¯at chisel end of the wheel wrench on an angle
through the hole between the body and the bumper.
Be sure the ¯at end connects into the hoist shaft.

Turn the ratchet counterclockwise to lower the spare tire
to the ground. If the spare tire does not lower to the
ground, the secondary latch is engaged causing the tire
not to lower. See ªSecondary Latch Systemº later in
this section.When the tire has been lowered, pull the tire toward you
so you can reach the tire retainer and pull it up
through the wheel opening.
If you have a vehicle which was completed from a cab
and chassis, refer to the information from the body
supplier/installer.
The spare tire is a full-size tire, like the other tires on
your vehicle.
Notice:To help avoid vehicle damage, do not drive
the vehicle before the cable is restored.

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 if the cable holding the spare tire
is damaged. For the secondary latch to work, the tire
must be stowed with the valve stem pointing down.
See ªStoring the Spare Tire and Toolsº later in
this section for instructions on storing the spare tire
correctly.
{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:
{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.
1. Check under the vehicle to see if the cable end is
visible.

2. If the cable is not visible, start this procedure at
Step 6.
3. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable is exposed.
4. Connect the jack handle (C) and jack handle
extension (B) together and press the retention
clip (arrow) so it engages.5. Attach the jack handle/jack handle extension to the
jack and slide the ratchet with the UP mark facing
you onto the end of the jack handle extension
so your set-up looks like the picture above.

6. Place the jack under the vehicle, ahead of the rear
bumper. Position the center lift point of the jack
under the center of the spare tire and turn the
handle clockwise to raise the jack until it lifts the
secondary latch spring.
7. Keep raising the jack until the spare tire stops
moving upward and is held ®rmly in place, this
lets you know that the secondary latch has
released. The secondary latch has released and
the spare tire is balancing on the jack.8. Lower the jack by turning the ratchet
counterclockwise. Keep lowering the jack until the
spare tire slides off the jack or is hanging by
the cable.
9. 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.
If the spare tire is hanging from the cable, slide the
ratchet onto the wheel wrench and insert the
wheel wrench into the hoist shaft hole above the
bumper and turn the wheel wrench counterclockwise
to lower the spare the rest of the way. Be sure
the DOWN mark on the ratchet is facing you.
10. Tilt the retainer at the end of the cable and pull it
through the wheel opening. Pull the tire out from
under the vehicle.
11. If the cable is hanging under the vehicle, turn the
wheel wrench in the hoist shaft hole in the bumper
clockwise to raise the cable back up.
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 repaired or replaced.
To continue changing the ¯at tire, return to Step 4 of
ªRemoving the Flat Tire and Installing the Spare
Tireº later in this section.

If the wheel has a smooth center piece, place the chisel
end of the wheel wrench in the slot on the wheel and
gently pry it out.
