In addition, your vehicle has a passenger sensing
system for the right front passenger’s position,
which includes sensors that are part of the
passenger’s seat. The passenger sensing system
may not operate properly if the original seat
trim is replaced with non-GM covers, upholstery or
trim, or with GM covers, upholstery or trim
designed for a different vehicle. Any object, such as
an aftermarket seat heater or a comfort enhancing
pad or device, installed under or on top of the
seat fabric, could also interfere with the operation of
the passenger sensing system. This could either
prevent proper deployment of the passenger
airbag(s) or prevent the passenger sensing system
from properly turning off the passenger airbag(s).
See Passenger Sensing System on page 1-85 .

Tire and Loading Information Label
A vehicle specic Tire and Loading Information
label is attached to the center pillar (B-pillar). With
the driver’s door open, you will nd the label
attached below the door lock post (striker). The tire
and loading information label shows the number of
occupant seating positions (A), and the maximum
vehicle capacity weight (B) in kilograms and
pounds.
The Tire and Loading Information label also shows
the size of the original equipment tires (C) and
the recommended cold tire ination pressures (D). For more information on tires and ination see
Tires on page 5-56 and Inflation - Tire Pressure on
page 5-62 .
There is also important loading information on the
vehicle Certication/Tire label. It tells you
the Gross Vehicle Weight Rating (GVWR) and the
Gross Axle Weight Rating (GAWR) for the front
and rear axles. See “Certication/Tire Label” later
in this section.
Steps for Determining Correct Load Limit 1.
Locate the statement “The combined weight of
occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle’s placard. 2.
Determine the combined weight of the driver
and passengers that will be riding in your
vehicle. 3.
Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4.
The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400 − 750 (5 x 150) = 650 lbs).Label Example

Certication/Tire Label
A vehicle specic Certication/Tire label is
attached to the rear edge of the driver’s door.
The label shows the size of your vehicle’s
original tires and the ination pressures needed
to obtain the gross weight capacity of your vehicle.
This is called Gross Vehicle Weight Rating
(GVWR). The GVWR includes the weight of
the vehicle, all occupants, fuel, and cargo.
The Certication/Tire label also tells you the
maximum weights for the front and rear axles,
called Gross Axle Weight Rating (GAWR). To
nd out the actual loads on your front and rear axles, you need to go to a weigh station
and weigh your vehicle. Your dealer can help
you with this. Be sure to spread out your
load equally on both sides of the center line.
Never exceed the GVWR for your vehicle, or
the GAWR for either the front or rear axle.
And, if you do have a heavy load, you should
spread it out.
{ CAUTION: Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
Your warranty does not cover parts or components
that fail because of overloading.
The label will help you decide how much cargo
and installed equipment your truck can carry.

Tires Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and where
to obtain service, see your vehicle Warranty
booklet for details.
{ CAUTION: Poorly maintained and improperly
used tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
exing. You could have an air-out and
a serious accident. See Loading Your
Vehicle on page 4-35 .
Underinated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked when
your tires are cold. See Inflation - Tire
Pressure on page 5-62 .
CAUTION: (Continued) CAUTION: (Continued)
Overinated tires are more likely to
be cut, punctured, or broken by a
sudden impact — such as when you
hit a pothole. Keep tires at the
recommended pressure.
Worn, old tires can cause accidents.
If your tread is badly worn, or if your
tires have been damaged, replace them.
See High-Speed Operation on page 5-63
for ination pressure adjustment for high
speed driving.
22-Inch Tires If your vehicle has the optional 22-inch
P285/45R22 size tires, they are classied as
touring tires and are designed for on-road use.
The low-prole, wide tread design is not
recommended for off-road driving. See Off-Road
Driving on page 4-12 , for additional information.

Tire Sidewall Labeling Useful information about a tire is molded into the
sidewall. The following illustration is an example
of a typical P-Metric tire sidewall.
(A) Tire Size :
The tire size code is a combination
of letters and numbers used to dene a particular
tire’s width, height, aspect ratio, construction
type, and service description. See the “Tire Size”
illustration later in this section for more detail. (B) TPC Spec (Tire Performance Criteria
Specication) :
Original equipment tires designed
to GM’s specic tire performance criteria have
a TPC specication code molded onto the sidewall.
GM’s TPC specications meet or exceed all
federal safety guidelines.
(C) DOT (Department of Transportation) :
The Department of Transportation (DOT) code
indicates that the tire is in compliance with the
U.S. Department of Transportation Motor Vehicle
Safety Standards.
(D) Tire Identication Number (TIN) :
The letters
and numbers following DOT code are the Tire
Identication Number (TIN). The TIN shows
the manufacturer and plant code, tire size, and
date the tire was manufactured. The TIN is molded
onto both sides of the tire, although only one side
may have the date of manufacture.
(E) Tire Ply Material :
The type of cord and
number of plies in the sidewall and under the
tread.
(F) Uniform Tire Quality Grading (UTQG) :
Tire manufacturers are required to grade
tires based on three performance factors:
treadwear, traction, and temperature resistance.
For more information, see Uniform Tire Quality
Grading on page 5-74 .Passenger (P-Metric) Tire
5-57

(G) Maximum Cold Ination Load Limit :
Maximum load that can be carried and the
maximum pressure needed to support that load.
For information on recommended tire pressure
see Inflation - Tire Pressure on page 5-62
and Loading Your Vehicle on page 4-35 .
Tire Size The following examples show the different parts of
a tire size.
(A) Passenger (P-Metric) Tire :
The United States
version of a metric tire sizing system. The letter P
as the rst character in the tire size means a
passenger vehicle tire engineered to standards set
by the U.S. Tire and Rim Association. (B) Tire Width :
The three-digit number indicates
the tire section width in millimeters from sidewall
to sidewall.
(C) Aspect Ratio :
A two-digit number that
indicates the tire height-to-width measurements.
For example, if the tire size aspect ratio is 75,
as shown in item C of the light truck (LT-Metric)
tire illustration, it would mean that the tire’s
sidewall is 75% as high as it is wide.
(D) Construction Code :
A letter code is used to
indicate the type of ply construction in the tire.
The letter R means radial ply construction;
the letter D means diagonal or bias ply construction;
and the letter B means belted-bias ply construction.
(E) Rim Diameter :
Diameter of the wheel in
inches.
(F) Service Description :
The service description
indicates the load range and speed rating of a
tire. The load index can range from 1 to 279.
Speed ratings range from A to Z.Passenger (P-Metric) Tire

called wear bars, that show across the tread of
a tire when only 1/16 inch (1.6 mm) of tread
remains. See When It Is Time for New Tires on
page 5-71 . UTQGS (Uniform Tire Quality Grading
Standards) :
A tire information system that
provides consumers with ratings for a tire’s
traction, temperature, and treadwear. Ratings are
determined by tire manufacturers using
government testing procedures. The ratings are
molded into the sidewall of the tire. See Uniform
Tire Quality Grading on page 5-74 .
Vehicle Capacity Weight :
The number of
designated seating positions multiplied by
150 lbs (68 kg) plus the rated cargo load.
See Loading Your Vehicle on page 4-35 .
Vehicle Maximum Load on the Tire :
Load on
an individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.

How to Check Use a good quality pocket-type gage to check
tire pressure. You cannot tell if your tires are
properly inated simply by looking at them. Radial
tires may look properly inated even when they
are underinated. Check the tire’s ination
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
pressure is low, add air until you reach the
recommended amount.
If you overll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Recheck the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out
dirt and moisture. High-Speed Operation
{ CAUTION: Driving at high speeds, 100 mph (160 km/h)
or higher, puts an additional strain on tires.
Sustained high-speed driving causes
excessive heat build up and can cause sudden
tire failure. You could have a crash and you or
others could be killed. Some high-speed rated
tires require ination pressure adjustment for
high speed operation. When speed limits and
road conditions are such that a vehicle can be
driven at high speeds, make sure the tires are
rated for high speed operation, in excellent
condition, and set to the correct cold tire
ination pressure for the vehicle load.
If your vehicle has P265/65R18 or P285/45R22 size tires
and you will be driving at high speeds, speeds of
100 mph (160 km/h) or higher, set the cold ination
pressure to 3 psi (20 kPa) above the recommended tire
pressure shown on the Tire and Loading Information
Label. When you end this high-speed driving, return the
tires to the cold ination pressure shown on the Tire and
Loading Information label. See Loading Your Vehicle on
page 4-35 and Inflation - Tire Pressure on page 5-62 .
5-63

Tire Pressure Monitor System The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in your
vehicle’s tires and transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inated to the ination
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire ination pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire ination
pressure label, you should determine the proper
tire ination pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one
or more of your tires is signicantly under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inate them to the proper
pressure. Driving on a signicantly under-inated tire
causes the tire to overheat and can lead to tire failure.
Under-ination also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling
and stopping ability. Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-ination
has not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will ash
for approximately one minute and then remain
continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur for
a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.
See Tire Pressure Monitor Operation on page 5-65 ,
for additional information.
