4. By rotating the wheel wrench clockwise, raise the vehicle until the wheel just
clears the surface.
WARNING!
Raising the vehicle higher than necessary can make the vehicle unstable. It could
slip off the jack and hurt someone near it. Raise the vehicle only enough to remove
the tire.
5. Remove the wheel nuts and pull the wheel off. Install the spare wheel and wheel nuts
with the cone shaped end of the nuts toward the wheel on single rear wheel (SRW)
models. On dual rear wheel models (DRW) the lug nuts are a two-piece assembly with
a flat face. Lightly tighten the nuts. To avoid risk of forcing the vehicle off the jack,
do not fully tighten the nuts until the vehicle has been lowered.
6. Using the wheel wrench, finish tightening the nuts using a crisscross pattern. Use
the following chart for the correct tightness of the lug nuts:
Lug Nut/Bolt Torque
Lug Nut/Bolt Type
**Lug Nut/Bolt Size
Lug Nut/Bolt
Socket Size
120-150 Ft-Lbs
(160-200 N·m)
Cone
M14 x 1.50
22 mm
130-160 Ft-Lbs
(190-220 N·m)
Flanged
If in doubt about the correct tightness, have them checked with a torque wrench
by your authorized dealer or at a service station.
WARNING!
A loose tire or jack thrown forward in a collision or hard stop could injure someone
in the vehicle. Always stow the jack parts and the extra tire and wheel in the places
provided.
7. Install wheel center cap (if equipped) and remove wheel blocks. Do not install chrome
or aluminum wheel center caps on the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the jack will not lower by turning the
dial (thumbwheel) by hand, it may be necessary to use the jack drive tube in order
to lower the jack. Stow the replaced tire, jack, and tools as previously described.
9. Adjust the tire pressure when possible.
