When rotating your vehicle’s tires, always use the
correct rotation pattern shown here.
Do not include the spare tire in the tire rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the Tire
and Loading Information label. SeeInation - Tire
Pressure on page 5-61andLoading Your Vehicle
on page 4-35.
Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 5-64.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 5-115.
{CAUTION:
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
you change a wheel, remove any rust or
dirt from 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 needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 5-78.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, tighten the cable. SeeStoring a Flat or
Spare Tire and Tools on page 5-94.
5-69

Wheel Replacement
Replace any wheel that is bent, cracked, or badly
rusted or corroded. If wheel nuts keep coming loose,
the wheel, wheel bolts, and wheel nuts should be
replaced. If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer/retailer if any of these conditions exist.
Your dealer/retailer will know the kind of wheel
you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset, and be mounted
the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor System (TPMS)
sensors, replace them only with new GM original
equipment parts. This way, you will be sure to have
the right wheel, wheel bolts, wheel nuts, and TPMS
sensors for your vehicle.{CAUTION:
Using the wrong replacement wheels, wheel
bolts, or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. 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.
SeeChanging a Flat Tire on page 5-78for more
information.

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 at tire creates a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
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 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 may
be very bumpy and noisy, but you can still steer.
Gently brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and
training. The jack provided with your vehicle
is designed only for changing a at tire.
If it is used for anything else, you or others
could be badly injured or killed if the vehicle
slips off the jack. Use the jack provided with
your vehicle only for changing a at tire.
If a tire goes at, the next part shows how to use the
jacking equipment to change a at tire safely.
5-77

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 vehicle’s
hazard warning ashers. SeeHazard Warning Flashers
on page 3-6for more information.{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 the shift lever in PARK (P).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will not
move, you should 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, at the opposite end of the vehicle.
5-78

Removing the Flat Tire and
Installing the Spare Tire
The tools that are needed include the jack (A), the
wheel blocks (B), the jack handle (C), the jack handle
extensions (D), and the wheel wrench (E).
1. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 5-78for more information.2. To remove the center cap, place the chiseled end
of the wheel wrench in the slot on the wheel and
gently pry the cap out.
5-84

{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.
4. Position the jack under the vehicle as shown.
Front Tire Flat:If the at tire is on a front tire of the
vehicle, you will need to use the jack handle (B) and
only one jack handle extension (C). Attach the wheel
wrench (D) to the jack handle extension (C). Attach
the jack handle (B) to the jack (A). Position the jack
on the frame behind the at tire near the front body
mount (E) as shown. 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.Front Position
5-86

Rear Tire Flat:If the at tire is on a rear tire of
the vehicle, use the jack handle (B) and both jack
handle extensions (C). Attach the wheel wrench (D)
to the jack handle 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.5. Remove all the
wheel nuts.
6. Take off the at tire.
Rear Position

{CAUTION:
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 you change a wheel,
remove any rust or dirt from 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 needed, to get all the rust or dirt off.
SeeChanging a Flat Tire on page 5-78.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces,
and spare wheel.8. Install the spare tire.{CAUTION:
Never use oil or grease on studs or nuts.
Because the nuts might come loose. The
vehicle’s wheel could fall off, causing a crash.
9. Put the wheel nuts back on with the rounded end
of the nuts toward the wheel after mounting the
spare tire.
10. Tighten each wheel nut by hand. Then use the
wheel wrench to tighten the wheel nuts until the
wheel is held against the hub.
11. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch system.
It is designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work, the
spare must be installed with the valve stem pointing
down. SeeStoring a Flat or Spare Tire and Tools
on page 5-94.
{CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly
and you and others could get hurt. Read and
follow the instructions listed next.To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable end is visible.
If the cable is not visible
proceed to Step 6.
2. If it is visible, rst try to tighten the cable by
turning the wheel wrench clockwise until you
hear two clicks or feel it skip twice. You cannot
overtighten the cable.
3. Loosen the cable by turning the wrench
counterclockwise three or four turns.
