9. Remove any rust or dirt from the wheel bolts,
mounting surfaces and spare wheel.
Rust or dirt on
the wheel, or on the parts to
which
it is fastened, can make the wheel nuts
become loose after
a time. The wheel could
come
off and cause an accident. When you
change a wheel, remove any rust or
dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to,
to get all the rust
or dirt off.
10. Put on the compact spare tire. Put the nuts on by
hand. Make sure the cone-shaped end is toward
the wheel. Tighten each nut by hand until the wheel
is held against the hub.
If a nut can’t be turned
by hand, use the extension and see your dealer as
soon as possible.
Never use oil or grease on studs or nuts. If you
do, the nuts might come
loose. Your wheel
could fall
off, causing a serious accident.

11. Lower the vehicle by turning the ratchet
counterclockwise. Lower the jack completely.

12. Tighten the wheel nuts
firmly in a crisscross
sequence as shown.
Turn the ratchet
clockwise with the
UP mark facing you.
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” in the Index 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”
in the index for the wheel nut torque specification.
13. Remove the wheel blocks.
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.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of fires 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.
Spare fuses and a fuse puller are located in the
underhood fuse block. You can remove fuses with
the fuse puller. Remember to replace any of the spare
fuses you use,
so you will have some if you ever
need them again.
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.
There are two fuse blocks in your vehicle: one
is inside
the vehicle and one is in the engine compartment.
Instrument Panel Fuse Block
The fuse block is located on the lower portion of the
instrument panel on the driver’s side.
