8. Proceed to the driver side rear
tire, and repeat the procedure
in Step 5.
9. After hearing the conrming horn
chirp for the driver side rear tire,
check to see if the TPMS low tire
warning light and the DIC LOW
TIRE messages have turned off.
If yes, the TPMS sensors have
been relearned. Turn the ignition
switch to LOCK/OFF.
If the low tire warning light and
the SERV TPM message on the
DIC are on after completing
Step 5 for the driver side rear tire,
the sensor relearn process has
not been successful. Turn the
ignition switch to LOCK/OFF and
repeat the matching process
beginning with Step 2.
10. Set all four tires to the
recommended air pressure level
as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the
valve stems.Tire Inspection and
Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire,
for signs of wear or damage.
SeeWhen It Is Time for
New Tires on page 5-58for
more information.
Tires should be rotated
every 5,000 to 8,000 miles
(8 000 to 13 000 km).
SeeScheduled Maintenance
on page 6-4.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the
vehicle continues to perform
most like it did when the
tires were new.Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
SeeWhen It Is Time for
New Tires on page 5-58and
Wheel Replacement on
page 5-64.
Make sure the spare tire is
stored securely. Push, pull and
then try to rotate or turn the
tire. If it moves, use the wheel
wrench/hoist shaft to tighten
the cable. SeeChanging a
Flat Tire on page 5-66.
Service and Appearance Care 5-57

When rotating the 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.
SeeInflation - Tire Pressure on
page 5-51andLoading the
Vehicle on page 4-35.Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on page 5-54.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications
on page 5-96.
{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 5-66.
When It Is Time for
New Tires
Various factors, such as
maintenance, temperatures,
driving speeds, vehicle loading,
and road conditions inuence
when you need new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which will appear when
the tires have only 1/16 inch
(1.6 mm) or less of tread remaining.
5-58 Service and Appearance Care

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 5-66for more information.
Used Replacement Wheels
{CAUTION
Putting a used wheel on the
vehicle is dangerous. You cannot
know how it has been used or how
far it has been driven. It could fail
suddenly and cause a crash. If you
have to replace a wheel, use a
new GM original equipment wheel.
5-64 Service and Appearance Care

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.
If a jack is provided with the
vehicle, it 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. If a jack
is provided with the vehicle, only
use it 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.
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.
SeeHazard Warning Flashers
on page 3-5.
{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
P (Park).

CAUTION (Continued)
3. If you have a
four-wheel-drive vehicle,
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.
To be even more certain the
vehicle will not move, 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.When the vehicle has a at tire,
the wheel blocks need to be set up
before changing it. The wheel
blocks are located in the tool bag in
the swing-gate for H3 models or
below the rear seat for H3T models.
SeeRemoving the Spare Tire
and Tools (H3) on page 5-68or
Removing the Spare Tire and
Tools (H3T) on page 5-69for
more information.
To use the wheel blocks, lift the
wheel block and lock it into place.Use the following example as a
guide to assist in the placement of
the wheel blocks (A) when the
vehicle has a at tire (B).
