NOTICE:
Use the proper towing equipment to avoid
damage to the bumper, fascia or fog lamp areas
of the vehicle.
With current trends in automotive styles and design, it is
essential that the correct towing equipment is used to
tow a vehicle. Your vehicle can be towed with wheel
-lift
or car
-carrier equipment.Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº in the Index.
Engine Overheating
You will find a coolant temperature gage or the warning
light about a hot engine on your vehicle's instrument
panel. See ªCoolant Temperature Gageº and ªLow
Coolant Warning Lightº in the Index.

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 the shift lever in PARK (P).
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.

5-23 Removing Wheel Covers and Wheel
Nut Caps
H±25±4001±R
To remove the wheel or nut
cap covers for your
particular vehicle, if you
have steel wheels with full
plastic wheel covers, loosen
each nut cap using the
wheel wrench.
Please note that nut caps will not remove from the
cover completely.
H±25±5057±R
If you have aluminum
wheels with nut caps,
remove them.
If you have aluminum wheels and a center cover hides the
wheel nuts, remove the center cover by using the flat end
of the wrench to pry it off. Do not drop the cover or lay it
face down, as it could become scratched or damaged.
Do not use a hammer or mallet on this type of cover.

3. Put the jack head into a notch in the frame which is
located near each wheel well. The front notch is
10 inches (25 cm) back from the front wheel well.
The rear notch is 8 inches (20 cm) forward from the
rear wheel well.
4. Position the jack and raise the jack head until it fits
firmly on the ridge in the vehicle's frame nearest the
flat tire. Do not raise the vehicle yet. Put the compact
spare tire near you.
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 fit the jack lift head into
the proper location before raising the vehicle.

5. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the spare tire
to fit.
6. Remove all the wheel nuts and take off the flat tire.

7. 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.

wheel
-mounting surface.

bolt is centered in each
wheel hole while
tightening the nuts.

hand until the wheel is
held against the hub.

11. Tighten the wheel
nuts firmly in a
crisscross sequence.
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.
Don't try to put the wheel cover on the compact
spare tire. It won't fit. Store the wheel cover in the
trunk until you have replaced the compact spare tire
with a regular tire.
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.
When you re-install the full size wheel and tire, you
install the wheel cover or nut caps at this point.
