4-17 Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary maintenance
and service work done. Check to make sure all
underbody shields (if so equipped) are properly
attached. Be sure you read all the information
about your four
-wheel-drive vehicle in this manual.
Is there enough fuel? Is the spare tire fully inflated?
Are the fluid levels up where they should be? What are
the local laws that apply to off
-roading where you'll
be driving? If you don't know, you should check with
law enforcement people in the area. Will you be on
someone's private land? If so, be sure to get the
necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about
how to load your vehicle.

The heaviest things should be on the load floor and
forward of your rear axle. Put heavier items as far
forward as you can.

Be sure the load is secured properly, so driving on
the off
-road terrain doesn't toss things around.
CAUTION:

Cargo on the load floor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.

Unsecured cargo on the load floor can
be tossed about when driving over
rough terrain. You or your passengers
can be struck by flying objects. Secure
the cargo properly.

Heavy loads on the roof raise the vehicle's
center of gravity, making it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the roof.
Keep cargo in the cargo area as far forward
and low as possible.
You'll find other important information in this manual.
See ªVehicle Loading,º ªLuggage Carrierº and ªTiresº
in the Index.

The following steps will tell you how to use the jack and
change a tire.
Removing the Spare Tire and Tools
The jacking equipment you will need is stored under
the rear seat of the vehicle. See ªRear Seatsº in the
Index for more information on accessing the jacking
equipment under the rear seat.

5-20
The tools you'll be using include the wheel wrench (A),
tire blocks (B), extension (socket end) (C), handle
(jack end) (D), and jack (E).
The following instructions explain how to remove the
spare tire mounted underneath your vehicle.
NOTICE:
Never remove or restow a tire from/to a stowage
position under the vehicle while the vehicle is
supported by a jack. Always tighten the tire fully
against the underside of the vehicle when restowing.
1. To remove the underbody-mounted spare, insert the
socket end of the extension, on an angle, into the
hole in the rear bumper. Be sure the socket end of
the extension connects into the hoist shaft.

5-21
2. Turn the wheel wrench counterclockwise to lower
the spare tire. Keep turning the wheel wrench
until the spare tire can be pulled out from under
the vehicle.
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 completely lowered, tilt the
retainer at the end of the cable and pull it through
the wheel opening. Pull the tire out from under
the vehicle.
NOTICE:
To help avoid vehicle damage, do not drive the
vehicle before the cable is properly stored.
3. Put the spare tire near the flat tire.
4. Use the chisel end of the wheel wrench to pry off
the center cap.
See ªRemoving the Flat Tire and Installing the
Spare Tireº later in this section to continue changing
the flat tire.

5-22
Secondary Latch System
The spare tire hoist assembly is 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 tire must be stored
with the valve stem pointing up. See ªStoring a Flat or
Spare Tire and Toolsº in the Index 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:
1. Check under the
vehicle to see if the
cable is visible.
2. If it is not visible, proceed to Step 6.
If visible, first 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.
4. Repeat this procedure at least two times.
If the spare tire lowers to the ground, continue with
Step 2 of ªRemoving the Spare Tire and Toolsº
earlier in this section.
5. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable is exposed.

5-23
6. Attach the jack handle, extension and the wheel
wrench to the jack and place it under the vehicle
towards the front of the rear bumper. Position the
center lift point of the jack under the center of the
spare tire.
7. Turn the wrench clockwise to raise the jack until it
lifts the end fitting.8. Continue raising the jack until the spare tire
stops moving upward and is held firmly in place.
The secondary latch has released and the spare tire
is balancing on the jack.
9. 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.
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 under the spare.

5-24
10. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while firmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert
the jack handle, extension and wheel wrench into
the hoist shaft hole in the bumper, on an angle,
and turn the wheel wrench counterclockwise to
lower the spare the rest of the way.11. Tilt the retainer at the end of the cable and pull it
through the wheel opening. Pull the tire out from
under the vehicle.
12. 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 flat tire using the
hoist assembly until it has been repaired or replaced.
To continue changing the flat tire, return to Step 2
of ªRemoving the Spare Tire and Toolsº earlier in
this Section.
