If a Tire Goes Flat
It's unusual for a tire to ªblow outº while you're driving,
especially if you maintain your tires properly. If air goes
out of a tire, it's much more likely to leak out slowly.
But if you should ever have a ªblowout,º here are a few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you'd use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
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.
To be even more certain the vehicle won't move,
you can put 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 of the
vehicle, at the opposite end.

Find the plastic screw heads in the trim panel over the
spare tire. (See ªCompact Spare Tireº in the Index for
more information about the compact spare.) Use a coin
or a key to turn the screw heads until the slots point
front and back to the unlock position. Gently lift the trim
panel's front forward edge and remove the panel.
If you have speakers in the trim panel, you may have to
disconnect the wire from the speaker. The speaker wire
may be long enough to remove the trim panel without
disconnecting the wire.To remove the jack and wheel wrench, loosen and
remove the bolt and remove the plastic cover.

Remove the wing nut and adapter and pull out the spare.The tools you'll be using include the jack (A) and
wheel wrench (B).

The jack has a bolt at the end. Attach the wheel wrench
to the jack bolt.
Turn the wheel wrench clockwise to raise the lift head
a little.
Your vehicle has alloy wheels. First remove the decorative
nut caps using the wheel wrench. Each wheel may have
one locknut in place of the standard wheel nut. A special
wheel lock key (removal tool) and instructions are located
in the center console. Attach the wheel lock key to the
socket of the wheel wrench. Remove the locking wheel
nut by turning counterclockwise.
Removing the Flat Tire and Installing the
Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts.
Don't remove them yet.

3. 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 fit.
4. Remove all the wheel nuts and take off the flat tire.
5. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
CAUTION:
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.

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.
6. Install the compact spare tire and 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.
7. Lower the vehicle by turning the wheel wrench
counterclockwise. Lower the jack completely.

8. Tighten the wheel
nuts firmly in a
crisscross sequence
as shown. Install
the plastic nut
caps and tighten
by hand.
Then, using the wheel wrench, tighten an additional
one
-quarter turn.
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 (140 N´m).
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.
Storing a Flat or Spare Tire and Tools
CAUTION:
Storing a jack, a tire or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
Return the jack, wheel wrench and flat tire using the
storage instructions. When you reinstall the trim panel,
be sure to tuck it under the weatherstrip.

Compact Spare Tire
Although the compact spare tire was fully inflated
when your vehicle was new, it can lose air after a time.
Check the inflation pressure regularly. It should
be 60 psi (420 kPa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
spare tire is correctly inflated. The compact spare is
made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full
-size tire
repaired or replaced where you want. Of course, it's best
to replace your spare with a full
-size tire as soon as you
can. Your spare will last longer and be in good shape in
case you need it again.
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.
Don't use your compact spare on other vehicles.
And don't mix your compact spare tire or wheel with
other wheels or tires. They won't fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won't fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don't use tire chains on your
compact spare.
