Changing a Flat Tire
If a tire goes ¯at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning ¯ashers.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake ®rmly.
2. Put an automatic transmission shift lever in
PARK (P), or shift a manual transmission to
FIRST (1) or REVERSE (R).
3. Turn off the engine and do not restart while
the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
CAUTION: (Continued)
CAUTION: (Continued)
Put the wheel blocks at the front and rear of
the tire farthest away from the one being
changed. That would be the tire on the other
side, at the opposite end of the vehicle.
When you have a ¯at tire, use the following example as a
guide to assist you in the placement of wheel blocks.
The following information will tell you next how to use
the jack and change a tire.

located in the trunk.
1. Open the trunk. See
Trunk on page 2-9for more
information.
2. Lift the cover to access the compact spare tire
and tools.3. Turn the retaining bolt on the compact spare tire
counterclockwise and remove it.
4. Then lift the compact spare tire out of the vehicle.
See
Compact Spare Tire on page 5-76for more
information.
5. Remove the jack, wheel wrench, wheel blocks, and
nut cap removal tool from the container in the trunk,
which are stored under the compact spare tire.

5. Put the compact spare tire near the ¯at tire.
{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to ®t the
jack lift head into the proper location before
raising the vehicle.6. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the compact
spare tire to ®t underneath the wheel well.
The jack handle must be unfolded to a right angle
before it is used.

10. Install the compact spare tire.
{CAUTION:
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. Put the wheel nuts back on with the rounded end of
the nuts toward the wheel. Tighten each nut by
hand until the wheel is held against the hub.
12. Lower the vehicle by turning the wheel wrench
counterclockwise. Lower the jack completely.
{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.
CAUTION: (Continued)
CAUTION: (Continued)
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 Speci®cations on page 5-90
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 Speci®cations on
page 5-90for the wheel nut torque speci®cation.
13. Tighten the wheel nuts
®rmly in a crisscross
sequence, as shown.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by fuses, circuit breakers and thermal links
in the wiring itself. This greatly reduces the chance of
®res caused by electrical problems.
Look at the metallic 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 correct size.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one. Just pick some feature
of your vehicle that you can get along without Ð like the
radio or cigarette lighter Ð and use its fuse, if it is the size
you need. Replace it as soon as you can.
Before replacing a fuse, turn every vehicle electrical
switch off.
There are two fuse blocks in your vehicle: the instrument
panel fuse block and the engine compartment fuse
block.
Instrument Panel Fuse Block
This fuse block is located under the driver's side of the
instrument panel. The fuses here protect each
separate circuit including headlamps. There are spare
fuses inside the fuse box. If you have electrical
failure, check here ®rst.
