Jacking the Vehicle

E162819

1.

Insert the jack handle into the pump
linkage.

2. Use an up-and-down motion with the

jack handle to raise the wheel
completely off the ground.

Note: Hydraulic jacks are equipped with a
pressure release valve that prevents lifting
loads which exceed the jack's rated
capacity.

3. Remove the lug nuts with the lug

wrench.

4. Replace the flat tire with the spare tire,

making sure the valve stem is facing
outward on all front an inboard rear
wheels. If you are replacing the
outboard wheel, the valve stem must
be facing inward. Reinstall the lug nuts
until the wheel is snug against the hub.
Do not fully tighten the lug nuts until
the wheel has been lowered.

5. Lower the wheel by slowly turning the

release valve counterclockwise.
Opening the release valve slowly will
provide a more controlled rate of
descent.

6. Remove the jack and fully tighten the

lug nuts in the order shown. See
Technical Specifications (page 419).

7.

Stow the flat tire. See Stowing the flat
or spare tire if the vehicle is equipped
with a spare tire carrier.

8. Stow the jack, jack handle and lug

wrench. Make sure the jack is securely
fastened so it does not rattle when
driving.

9. Unblock the wheels.

3. Use your hand or rubber mallet to tap

the ornament in a star pattern. There
should be an even gap between the
ornament and the wheel.

4. Be sure to install all the clips on the

nuts over the flanges so that there is
an even gap all around and the
retention clips are fully seated.

Stowing the Flat or Spare Tire

Note: Failure to follow spare tire stowage
instructions may result in failure of cable or
loss of spare tire.

Note: If you are stowing a tire that requires
reattaching it to the vehicle with a tether,
perform these steps first, then proceed with
the following steps.

1.

Place the tire on end with the valve
stem facing toward the front of the
vehicle.

2. Place the tether into the bolt holes in

the wheel and attach the lug nut using
the lug wrench.

E162800

3. Lay the tire on the ground with the

valve stem facing up.

4. Slide the wheel partially under the

vehicle and install the retainer through
the wheel center. Pull on the cable to
align the components at the end of the
cable.

5. Turn the jack handle clockwise until

the tire is raised to its stowed position
underneath the vehicle. The effort to
turn the jack handle increases
significantly and the spare tire carrier
ratchets or slips when the tire is raised

to the maximum tightness. Tighten to
the best of your ability, to the point
where the ratchet/slip occurs, if
possible. The spare tire carrier will not
allow you to overtighten. If the spare
tire carrier ratchets or slips with little
effort, take the vehicle to your
authorized dealer for assistance at your
earliest convenience.

6. Check that the tire lies flat against the

frame and is properly tightened. Try to
push or pull, then turn the tire to be
sure it will not move. Loosen and
retighten, if necessary. Failure to
properly stow the spare tire may result
in failure of the winch cable and loss
of the tire.

7.

Repeat this tightness check procedure
when servicing the spare tire pressure
(every six months, per scheduled
maintenance information), or at any
time that the spare tire is disturbed
through service of other components.

8. If removed, install the spare tire lock

into the bumper drive tube with the
spare tire lock key and jack handle.
