{WARNING
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.Notice:
The wrong wheel can
also cause problems with
bearing life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle ground
clearance, and tire or tire chain
clearance to the body and
chassis.
See If a Tire Goes Flat on
page 10‑71 for more information.
Used Replacement Wheels
{WARNING
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.

If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially if
you maintain your vehicle's tires
properly. If air goes out of a tire,
it is much more likely to leak out
slowly. But if you should ever have a
blowout, here are a few tips about
what to expect and what to do:
If a front tire fails, the flat tire
creates 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 off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction
you would 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 maybe very bumpy and noisy, but you
can still steer. Gently brake to a
stop, well off the road, if possible.
{WARNING
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has
been driven on while severely
underinflated or flat may cause
a blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{WARNING
Lifting a vehicle and getting
under it to do maintenance or
repairs is dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If your vehicle is a hybrid, see the
hybrid supplement for more
information.

If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. SeeHazard
Warning Flashers on page 6‑5.
{WARNING
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 firmly.
2. Put the shift lever in P (Park).
3. If you have a four-wheel-drive vehicle
with a N (Neutral) transfer
(Continued)
WARNING (Continued)
case position, be sure the
transfer case is in a drive
gear—not in N (Neutral).
4. Turn off the engine and do not restart while the vehicle
is raised.
5. Do not allow passengers to remain in the vehicle.
6. 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 the vehicle has a flat tire (B),
use the following example as a
guide to assist you in the placement
of wheel blocks (A).

retainer and pull it through the
center of the wheel along with
the cable and latch.

Flat on page 10‑71 for more
information.
2. If your vehicle has a center cap that covers the wheel fasteners,
place the chisel end of the wheel
wrench in the slot on the wheel
and gently pry the cap out. If the wheel has a bolt-on hub
cap, loosen the plastic nut caps
by turning the wheel wrench
counterclockwise. The plastic
nut caps will be retained in the
hub cap after it is removed from
the wheel.3. Use the wheel wrench to loosen
all the wheel nuts. Turn the
wheel wrench counterclockwise

extensions (C). Attach the jack
handle (B) to the jack (A). Use
the jacking pad provided on
the rear axle. Turn the wheel
wrench (D) clockwise to raise the
vehicle. Raise the vehicle far
enough off the ground so there
is enough room for the spare tire
to clear the ground.
{WARNING
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.
{WARNING
Raising the 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. Remove all of the wheel nuts.
6. Take off the flat tire.

7. Remove any rust or dirt from thewheel bolts, mounting surfaces,
and spare wheel.
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, use a cloth or a
paper towel to do this; but be sure
to use a scraper or wire brush
later, if needed, to get all the rust
or dirt off. See If a Tire Goes Flat
on page 10‑71.
8. Put the wheel nuts back on with the rounded end of the nuts
toward the wheel after mounting
the spare tire.
{WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
9. Tighten each wheel nut by hand. Then use the wheel wrench to
tighten the nuts until the wheel is
held against the hub.
10. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack
completely.
