tighten the wheel nuts
rmly in a crisscross
sequence as shown.
{CAUTION:
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 (140Y).

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 ination pressure regularly. After installing the
compact spare on your vehicle, stop as soon as possible
and make sure it’s correctly inated. 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.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of res
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure
you replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without — like the radio or
cigarette lighter — and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
Instrument Panel Fuse Block
The instrument panel fuse
block is located at the end
of the instrument panel
on the driver’s side of the
vehicle.
Remove the cover by turning the fastener
counterclockwise. Extra fuses and the fuse extractor
are provided in the cover. To reinstall the fuse
panel cover, push in and turn the fastener clockwise.

Footnotes
†The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
#Lubricate the front suspension, ball joints, steering
linkage, parking brake cable guides, propshaft splines,
universal joints and brake pedal springs.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-32.
**Drive axle service. See Part D: Recommended Fluids
and Lubricants on page 6-33 for proper lubricant to use:
Check uid level and add uid as needed. If driving in
dusty areas or when towing a trailer, drain uid and
rell every 15,000 miles (25 000 km).
If your vehicle has a locking differential, drain uid
and rell at rst engine oil change.
More frequent lubrication may be required for
heavy-duty or off-road use.

❑Change engine oil and lter (or every 3 months,
whichever occurs rst).An Emission Control Service.
❑Lubricate chassis components (or every 3 months,
whichever occurs rst).(See footnote #.)
❑Check rear/front axle uid level and add uid as
needed. Check constant velocity joints and axle seals
for leaking.(See footnote **.)
