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 specification. See
Capacities and Specifications on page 436
for wheel nut torque specification.
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 specification. See
Capacities and Specifications on page 436 for
the wheel nut torque specification.
Notice: Wheel covers will not fit on your
compact spare. If you try to put a wheel cover
on the compact spare, you could damage
the cover or the spare.
Do not try to put the wheel cover on the compact
spare tire. It will not fit. Store the wheel cover
in the trunk until you have the flat tire repaired or
replaced.
12. Tighten the wheel
nuts firmly in a
crisscross sequence
as shown.
