When installing the wheel center
ornaments, make sure that the ornament
retention towers on the back side of the
ornament are aligned with the studs or lug
nuts. The retention towers are designed to
be installed over the studs or nuts and
retain to the flange on the lug nut.

E162821

If the ornament retention towers are
aligned between the studs or lug nuts, the
ornament is improperly installed. This
improper installation may appear and
sound correct, but will not keep the
ornament on the vehicle. Ornaments
improperly installed in this manner will fall
off or become loose with minimal force or
impact.

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 409).

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.
