{CAUTION:
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the wheel
to come 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
the proper torque speci cation. See
Capacities and Specifications on page 518
for wheel nut torque speci cation.
Notice:Improperly tightened wheel nuts can
lead 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. See
Capacities and Specifications on page 518for
the wheel nut torque speci cation.11. Tighten the nuts
rmly in a crisscross
sequence as
shown by turning
the wheel wrench
clockwise.
When you reinstall the full-size wheel and tire, you
must also reinstall the wheel cover with attached
plastic nuts, the plastic nut caps, or the smooth
center cap.
If you are reinstalling a wheel cover with
attached plastic nuts, place it on the wheel and
tighten the nuts by hand to get them started.
Then tighten the nut caps with the wheel
wrench until they are snug. Do not overtighten
the nut caps or they may break.
If you are reinstalling plastic nut caps, tighten
the nuts by hand to get them started. Then
tighten the nut caps with the wheel wrench
until they are snug. Do not overtighten the nut
caps or they may break.

Spare Tire
Your vehicle, when new, had a fully-in ated spare
tire. A spare tire may lose air over time, so check its
in ation pressure regularly. SeeIn ation - Tire
Pressure on page 460andLoading Your Vehicle on
page 372for information regarding proper tire
in ation and loading your vehicle. For instruction on
how to remove, install, or store a spare tire, see
Removing the Flat Tire and Installing the Spare Tire
on page 482andStoring a Flat or Spare Tire and
Tools on page 492.After installing the spare tire on your vehicle, you
should stop as soon as possible and make
sure the spare is correctly in ated. Have the
damaged or at road tire repaired or replaced as
soon as you can and installed back onto your
vehicle. This way, a spare tire will be available in
case you need it again.
Your vehicle may have a different size spare tire
than the road tires, those originally installed on your
vehicle. This spare tire was developed for use on
your vehicle, so it is all right to drive on it.
