Tire Pressure Monitor
Operation This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
the tires and transmit the tire
pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument cluster.
If the warning light comes on, stop
as soon as possible and inflate the
tires to the recommended pressure shown on the Tire and Loading
Information label. See Vehicle Load
Limits 0 200 .
A message to check the pressure in
a specific tire displays in the Driver
Information Center (DIC). The low
tire pressure warning light and the
DIC warning message come on at
each ignition cycle until the tires are
inflated to the correct inflation
pressure. If the vehicle has DIC
buttons, tire pressure levels can be
viewed. For additional information
and details about the DIC operation
and displays, see Driver Information
Center (DIC) 0 151 .
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the
air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information label
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when they are cold. See Vehicle Load
Limits 0 200 , for an example of the
Tire and Loading Information label
and its location. Also see Tire
Pressure 0 327 .
The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire
maintenance. See Tire Inspection
0 333 , Tire Rotation 0 334 and Tires
0 320 .
CautionTire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle.

334 Vehicle Care .
The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric..
The tire has a bump, bulge,
or split..
The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule 0 370 .
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the rotation, check the wheel
alignment.
See When It Is Time for New
Tires 0 335 and Wheel
Replacement 0 339 .
Use this rotation pattern when
rotating the tires.
Do not include the spare tire in
the tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after the tires have been rotated.
See Tire Pressure 0 327 and
Vehicle Load Limits 0 200 .
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation 0 330 .
Check that all wheel nuts are
properly tightened. See “ Wheel
Nut Torque ” under Capacities
and Specifications 0 384 .
{ WarningRust 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, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.

Jacking Locations (Overall View)
4. Position the jack under the
vehicle, as shown.
Left Front Shown, Right Front
Similar
Front Tire Flat: If the flat tire is
on a front tire of the vehicle,
use the jack handle and only one jack handle extension.
Attach the wheel wrench to the
jack handle extension. Attach
the jack handle to the jack.
Position the jack on the frame
behind the flat tire where the
frame sections overlap. Turn
the wheel wrench 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.
Rear Position
Rear Tire Flat: If the flat tire is
on a rear tire of the vehicle,
use the jack handle (2) and both jack handle
extensions (3). Attach the
wheel wrench (4) to the jack
handle extensions (3). Attach
the jack handle (2) to the
jack (1). Use the jacking
pad (5) provided on the rear
axle. Turn the wheel wrench (4)
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.
{ WarningGetting under a vehicle when it is
lifted on a jack 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.

{ WarningRaising 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
the wheel bolts, mounting
surfaces, and spare wheel.
{ WarningRust 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, a cloth or a paper
(Continued) Warning (Continued) towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
8. Put the wheel nuts back on
with the rounded end of the
nuts toward the wheel after
mounting the spare tire.
{ WarningNever 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.
