11. Tighten the wheel nuts firmly in a
crisscross sequence.
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become 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
(140 Nom).
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.
Don’t try to put the wheel cover on the compact
spare tire. It won’t fit. Store the wheel cover in the
trunk until
you have replaced the compact spare tire
with a regular tire.
NOTICE:
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.
When you re-install the full size wheel and tire, you
install
the wheel cover or nut caps at this point.

Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads
for wear and rotors
for surface condition.
Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving habits
or conditions result in frequent braking.
CaliperKnuckle Maintenance Inspection
If you operate your vehicle in a highly corrosive
environment, as indicated by the shaded areas on the
map following
this text, your vehicle may require
additional brake service. Refer to the appropriate
GM
Service Bulletin for the proper caliper inspection
procedure.
As necessary, caliper pins and knuckle brake
pad abutments should be lubricated at every other tire
rotation.
Also, see your GM dealer’s service department
or qualified service center for additional information.
