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 on your
vehicle, excluding the spare tire. The TPMS sensors
monitor the air pressure in your vehicle’s 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 panel cluster.
At the same time, a Driver Information Center (DIC)
message is displayed on the DIC display screen.
The low tire pressure warning light and the DIC warning
message come on at each ignition cycle until the
tires are inated to the correct ination pressure.
For additional information and details about the DIC
operation and displays seeDIC Operation and Displays
on page 3-35andDIC Warnings and Messages on
page 3-38.The low tire pressure warning light may come on in cool
weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle’s original
equipment tires and the correct ination pressure for
your vehicle’s tires when they are cold. SeeLoading the
Vehicle on page 4-33, for an example of the Tire and
Loading Information label and its location on your
vehicle. Also seeInflation - Tire Pressure on page 5-61.
Your vehicle’s TPMS can warn you about a low tire
pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation on
page 5-68andTires on page 5-54.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not covered
by your warranty. Do not use liquid tire sealants.

You need new tires if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
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.
The rubber in tires degrades over time, even if they are
not being used. This is also true for the spare tire, if
your vehicle has one. Multiple conditions affect how fast
this aging takes place, including temperatures, loading
conditions, and ination pressure maintenance. With
proper care and maintenance tires will typically wear out
before they degrade due to age. If you are unsure
about the need to replace your tires as they get older,
consult the tire manufacturer for more information.
Buying New Tires
GM has developed and matched specic tires for your
vehicle. The original equipment tires installed on
your vehicle, when it was new, were designed to meet
General Motors Tire Performance Criteria Specication
(TPC spec) system rating. If you need replacement
tires, GM strongly recommends that you get tires with
the same TPC Spec rating. This way, your vehicle
will continue to have tires that are designed to give the
same performance and vehicle safety, during normal
use, as the original tires.
GM’s exclusive TPC Spec system considers over a
dozen critical specications that impact the overall
performance of your vehicle, including brake system
performance, ride and handling, traction control, and tire
pressure monitoring performance. GM’s TPC Spec
number is molded onto the tire’s sidewall near the tire
size. If the tires have an all-season tread design,
the TPC spec number will be followed by an MS for
mud and snow. SeeTire Sidewall Labeling on page 5-55
for additional information.
5-70

GM recommends replacing tires in sets of four. This is
because uniform tread depth on all tires will help keep
your vehicle performing most like it did when the tires
were new. Replacing less than a full set of tires can affect
the braking and handling performance of your vehicle.
SeeTire Inspection and Rotation on page 5-68for
information on proper tire rotation.
{CAUTION:
Mixing tires could cause you to lose control of
your vehicle while driving. If you mix tires of
different sizes, brands, or types (radial and
bias-belted tires) the vehicle may not handle
properly, and you could have a crash. Using tires
of different sizes, brands, or types may also cause
damage to your vehicle. Be sure to use the correct
size, brand, and type of tires on all wheels.
Your vehicle may have a compact spare tire and
wheel assembly. It is all right to drive with your
vehicle’s compact spare tire temporarily. It was
developed for use on your vehicle. SeeSpare Tire
on page 5-98.
{CAUTION:
If you use bias-ply tires on the vehicle, the
wheel rim anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on the vehicle.
If you must replace your vehicle’s tires with those that do
not have a TPC Spec number, make sure they are the
same size, load range, speed rating, and construction
type (radial and bias-belted tires) as your vehicle’s
original tires.
Vehicles that have a tire pressure monitoring system
could give an inaccurate low-pressure warning if
non-TPC Spec rated tires are installed on your vehicle.
Non-TPC Spec rated tires may give a low-pressure
warning that is higher or lower than the proper warning
level you would get with TPC Spec rated tires. SeeTire
Pressure Monitor System on page 5-63.
Your vehicle’s original equipment tires are listed on the
Tire and Loading Information Label. SeeLoading the
Vehicle on page 4-33, for more information about the Tire
and Loading Information Label and its location on your
vehicle.
5-71

Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may affect
the way your vehicle performs, including its braking, ride
and handling characteristics, stability, and resistance to
rollover. Additionally, if your vehicle has electronic
systems such as, antilock brakes, traction control, and
electronic stability control, the performance of these
systems can be affected.
{CAUTION:
If you add different sized wheels, your vehicle may
not provide an acceptable level of performance and
safety if tires not recommended for those wheels
are selected. You may increase the chance that you
will crash and suffer serious injury. Only use GM
specic wheel and tire systems developed for your
vehicle, and have them properly installed by a GM
certied technician.
SeeBuying New Tires on page 5-70andAccessories
and Modifications on page 5-3for additional information.
Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use spare
tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
5-72

Tire Chains
{CAUTION:
If your vehicle has P215/70R16, P235/75R16,
P265/70R17, or P235/50R18 size tires, do not
use tire chains. They can damage your vehicle
because there is not enough clearance. Tire
chains used on a vehicle without the proper
amount of clearance can cause damage to the
brakes, suspension, or other vehicle parts. The
area damaged by the tire chains could cause you
to lose control of your vehicle and you or others
may be injured in a crash.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s instructions.
CAUTION: (Continued)
CAUTION: (Continued)
To help avoid damage to your vehicle, drive
slowly, readjust, or remove the device if it is
contacting your vehicle. Do not spin the vehicle’s
wheels.
If you do nd traction devices that will t, install
them on the rear tires.
Notice:If your vehicle has a tire size other than
P215/70R16, P235/75R16, P265/70R17, or P235/50R18
use tire chains only where legal and only when
you must. Use chains that are the proper size for
your tires. Install them on the tires of the rear axle.
Do not use chains on the tires of the front axle.
Tighten them as tightly as possible with the ends
securely fastened. Drive slowly and follow the chain
manufacturer’s instructions. If you can hear the
chains contacting your vehicle, stop and retighten
them. If the contact continues, slow down until
it stops. Driving too fast or spinning the wheels with
chains on will damage your vehicle.

Spare Tire
Compact Spare Tire
Your vehicle may have a compact spare tire. Although
the compact spare tire was fully inated when your
vehicle was new, it can lose air over time. Check the
ination pressure regularly. It should be 60 psi (420 kPa).
Notice:If the vehicle has four-wheel drive and the
compact spare tire is installed on the vehicle, do not
drive in four-wheel drive until you can have the at
tire repaired and/or replaced. You could damage the
vehicle, and the repair costs would not be covered by
your warranty. Never use four-wheel drive when the
compact spare tire is installed on the vehicle.
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
vehicle’s spare tire is correctly inated. The compact
spare is made to perform well at speeds up to 62 mph
(100 km/h) for distances up to 500 miles (804 km).For heavy payloads or towing, and for low traction or
four-wheel-drive conditions, repair or replace the full-size
tire. Of course, it is best to replace your vehicle’s spare
with a full-size tire as soon as you can. The spare tire
will last longer and be in good shape in case you need
it again.
Notice:When the compact spare is installed, do
not take the vehicle through an automatic car wash
with guide rails. The compact spare can get
caught on the rails which can damage the tire,
wheel and other parts of the vehicle.
Do not use your compact spare on other vehicles.
And do not mix your compact spare tire or wheel with
other wheels or tires. They will not t. Keep your
spare tire and its wheel together.
Notice:Tire chains will not t the compact spare.
Using them can damage the vehicle and can damage
the chains too. Do not use tire chains on the compact
spare.
5-98

Full-Size Spare Tire
Your vehicle may have a full-size spare tire, which, when
new, was fully inated. A spare tire may lose air over
time, so check its ination pressure regularly. See
Inflation - Tire Pressure on page 5-61andLoading the
Vehicle on page 4-33for information regarding proper tire
ination and loading your vehicle. For instruction on how
to remove, install, or store a spare tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-83and
Storing a Flat or Spare Tire and Tools on page 5-94.
Your vehicle may have a different size spare tire than
the road tires originally installed on your vehicle.
This spare was developed for use on your vehicle, so it
is alright to drive on it. If your vehicle has four-wheel
drive and the different size spare tire is installed, keep
the vehicle in two-wheel drive.
Notice:If the vehicle has four-wheel drive and the
different size spare tire is installed on the vehicle,
do not drive in four-wheel drive until you canhave your at tire repaired and/or replaced. You
could damage the vehicle, and the repair costs
would not be covered by your warranty. Never use
four-wheel drive when the different size spare
tire is installed on the vehicle.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. The spare tire is made to perform well
at speeds up to 62 mph (100 km/h) for distances up
to 500 miles (804 km). For heavy payloads or towing,
and for low traction or four-wheel-drive conditions, repair
or replace the full-size tire. Have the damaged or at
road tire repaired or replaced as soon as you can
and installed back onto your vehicle. This way, the spare
tire will be available in case you need it again.
Do not mix tires and wheels of different sizes, because
they will not t. Keep your spare tire and its wheel
together.
