{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 437
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 437
for the wheel nut torque speci cation.11. Tighten the
wheel nuts rmly
in a crisscross
sequence as
shown by turning
the wheel wrench
clockwise.
When you reinstall the regular wheel and tire,
you must also reinstall the center cap. Place
the cap on the wheel and tap it into place until
it seats ush with the wheel. The cap only goes
on one way. Be sure to line up the tab on the
center cap with the indentation on the wheel.
For the Xtreme, tighten each nut cap by hand,
then tighten an additional one quarter of a turn
with the wheel wrench.

proper hook-up, binding, leaks, cracks, cha ng,
etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect drum brake
linings/shoes for wear or cracks. Inspect other
brake parts, including drums, wheel cylinders,
calipers, parking brake, etc. Check parking
brake adjustment.
(b)Visually inspect front and rear suspension
and steering system for damaged, loose, or
missing parts or signs of wear. Inspect power
steering lines and hoses for proper hook-up,

constant velocity joints, rubber boots, and axle
seals for leaks.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings, and clamps; replace
with genuine parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.(d)Inspect wiper blades for wear, cracking,
or contamination. Clean the windshield and wiper
blades, if contaminated. Replace wiper blades
that are worn or damaged. See Windshield
Wiper Blade Replacement on page 375and
Windshield and Wiper Blades on page 427for
more information.
(e)Make sure the safety belt reminder light and
all your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for any
other loose or damaged safety belt system parts.
If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced.
Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.
(f)Lubricate all key lock cylinders, body door
