10. Use the wrench to
tighten the wheel nuts
®rmly in a crisscross

{CAUTION:
Incorrect wheel nuts or improperly tightened

loose and even come off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to
100 lb-ft (140Y).

to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque speci®cation.

installed)Compact Spare Tire
The compact spare tire is a temporary replacement tire
made to perform at speeds up to 65 mph (105 km/h)
and for distances up to 3,000 miles (5 000 km). With the
compact spare installed, you can ®nish your trip and
then have the damaged or ¯at road tire repaired
or replaced. Of course, it's best to repair or replace the
damaged road tire as soon as you can. Your compact
spare tire will last longer and be in good shape in case
you need it again.
The compact spare may lose air after a time, so check
the in¯ation pressure regularly. After installing the
compact spare on your vehicle, stop as soon as possible
and make sure it's correctly in¯ated. It should be 60
psi (420 kPa).
Don't use your compact spare tire on other vehicles and
don't mix your compact spare tire or wheel with other
wheels or tires, they won't ®t. Keep your compact spare
and its wheel together. Don't include the compact
spare in your tire rotation.
Notice:When the compact spare is installed, don't
take your vehicle through an automatic car wash
with guide rails. The compact spare can get caught
on the rails. That can damage the tire and wheel,
and maybe other parts of your vehicle.
