Your vehicle has one
double
-sided key for the
ignition and all door locks
as well as the spare tire
hoist lock.
Your vehicle may also have
a key that locks and unlocks
the center floor console
only (if equipped).
If you ever lose your keys, your dealer will be able to
assist you with obtaining replacements.
Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked,
the handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.

4-19 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.

Follow these instructions to lower the spare tire:
1. If the vehicle is equipped with a hoist lock, open the
spare tire lock cover on the bumper and use the
ignition key to remove the lock.
2. Assemble the wheel wrench and the two jack handle
extensions as shown. Insert the hoist end (open end)
of the extension through the hole in the rear bumper.
Be sure the hoist end of the extension connects into
the hoist shaft (the ribbed square end of the
extension is used to lower the spare tire).
3. Turn the wheel wrench counterclockwise to lower
the spare tire to the ground. Continue to turn the
wheel wrench until the spare tire can be pulled out
from under the vehicle. The wheel wrench has a
hook that allows you to pull the hoist cable towards
you, to assist in reaching the spare tire.
4. When the tire has been lowered, tilt the retainer at
the end of the cable so it can be pulled up through
the wheel opening.
5. Put the spare tire near the flat tire.
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).
If the flat tire is on the rear of the vehicle, you'll need
to use both jack handle extensions.

If your vehicle has wheel
nut caps, loosen them by
turning the wheel wrench
counterclockwise. If you
have a center cap with
wheel nut caps, the wheel
nut caps are designed to
remain with the center cap.
Remove the center cap.
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 out.Removing the Flat Tire and Installing the
