Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicleshould be serviced. There are partsof the airbag system in severalplaces around the vehicle. Yourdealer and the service manual haveinformation about servicing thevehicle and the airbag system. Topurchase a service manual, seeService Publications OrderingInformation0321.
{Warning
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change thevehicle's frame, bumper system,height, front end, or side sheetmetal, may keep the airbag systemfrom working properly. Theoperation of the airbag system canalso be affected by changing anyparts of the front seats, safety belts,the airbag sensing and diagnosticmodule, steering wheel, instrumentpanel, any of the airbag modules,ceiling or pillar garnish trim, frontsensors, or airbag wiring.
Yo u r d e a l e r a n d t h e s e r v i c e m a n u a lhave information about the locationof the airbag sensors, sensing anddiagnostic module, and airbagwiring.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0269for additionalimportant information.
If you have to modify your vehiclebecause you have a disability andyou have questions about whetherthe modifications will affect the
vehicle's airbag system, or if youhave questions about whether theairbag system will be affected if thevehicle is modified for any otherreason, call Customer Assistance.SeeCustomer AssistanceOffices0314.
Airbag System Check
The airbag system does not needregularly scheduled maintenance orreplacement. Make sure the airbagreadiness light is working. SeeAirbag Readiness Light099.

Tire and Loading InformationLabel
Label Example
AvehiclespecificTireand
Loading Information label is
attached to the center pillar
(B-pillar). The tire and loading
information label shows the
number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
size of the original equipment
tires (3) and the recommended
cold tire inflation pressures (4).
For more information on tires
and inflation seeTires0252
andTire Pressure0260.
There is also important loading
information on the vehicle
Certification/Tire label. It may
show the Gross Vehicle Weight
Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for
the front and rear axle. See
“Certification/Tire Label”later in
this section.
“Steps for Determining CorrectLoad 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 figure equals
the available amount of
cargo and luggage load
capacity. For example, if the
"XXX" amount equals
1400 lbs. and there will be
five 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.)
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.

174 Driving and Operating
Example 3
1. Maximum Vehicle CapacityWeight for Example 3 =453 kg (1,000 lbs)
2. Subtract Occupant Weight@91kg(200lbs)◊5=453 kg (1,000 lbs)
3. Available Cargo Weight =0kg (0lbs)
Refer to the vehicle tire and
loading information label for
specific information about the
vehicle's capacity weight and
seating positions. The combined
weight of the driver, passengers,
and cargo should never exceed
the vehicle capacity weight.
Certification/Tire Label
AvehiclespecificCertification/
Tire label is attached to the
center pillar (B-pillar). The label
may show the size of the
vehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of the vehicle. This is called
Gross Vehicle Weight Rating
(GVWR). The GVWR includes
the weight of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label also
may show the maximum weights
for the front and rear axles,
called Gross Axle Weight Rating
(GAWR). To find out the actual
loads on the front and rear
axles, you need to go to a weigh
station and weigh the vehicle.
Yo u r d e a l e r c a n h e l p y o u w i t h
this. Be sure to spread out the
load equally on both sides of the
centerline.
{Warning
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the cargo
area of the vehicle. Try to
spread the weight evenly.

All-Season Tires
This vehicle may come withall-season tires. These tires aredesigned to provide good overallperformance on most road surfacesand weather conditions. Originalequipment tires designed to GM'sspecific tire performance criteriahave a TPC specification codemolded onto the sidewall. Originalequipment all-season tires can beidentified by the last two charactersof this TPC code, which willbe“MS.”
Consider installing winter tires onthe vehicle if frequent driving onsnow or ice-covered roads isexpected. All-season tires provideadequate performance for mostwinter driving conditions, but theymay not offer the same level oftraction or performance as wintertires on snow or ice-covered roads.SeeWinter Tires0253.
Winter Tires
This vehicle was not originallyequipped with winter tires. Wintertires are designed for increasedtraction on snow and ice-coveredroads. Consider installing wintertires on the vehicle if frequentdriving on ice or snow coveredroads is expected. See your dealerfor details regarding winter tireavailability and proper tire selection.Also, seeBuying New Tires0268.
With winter tires, there may bedecreased dry road traction,increased road noise, and shortertread life. After changing to wintertires, be alert for changes in vehiclehandling and braking.
If using winter tires:
.Use tires of the same brand andtread type on all four wheelpositions.
.Use only radial ply tires of thesame size, load range, andspeed rating as the originalequipment tires.
Winter tires with the same speedrating as the original equipment tiresmay not be available for H, V, W, Y,and ZR speed rated tires. If wintertires with a lower speed rating arechosen, never exceed the tire'smaximum speed capability.
All-Terrain Tires
This vehicle may have All-TerrainTires. These tires provide goodperformance on most road surfaces,weather conditions, and for off-roaddriving.
The tread pattern on these tires maywear more quickly than other tires.Consider rotating the tires morefrequently than at 12 000 km(7,500 mi) intervals if irregular wearis noted when the tires areinspected. SeeTireInspection0265.

Tire Sidewall Labeling
Useful information about a tire is
molded into the sidewall. The
examples show a typical
passenger vehicle and light
truck tire sidewall.
Passenger (P-Metric) Tire
(1) Tire Size:The tire size code
is a combination of letters and
numbers used to define 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.
(2) TPC Spec (Tire
Performance Criteria
Specification):Original
equipment tires designed to
GM's specific tire performance
criteria have a TPC specification
code molded onto the sidewall.
GM's TPC specifications meet or
exceed all federal safety
guidelines.
(3) 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.
DOT Tire Date of
Manufacture:The last four
digits of the TIN indicate the tire
manufactured date. The first two
digits represent the week
(01-52) and the last two digits,
the year. For example, the third
week of the year 2010 would
have a four-digit DOT date
of 0310.
(4) Tire Identification Number
(TIN):The letters and numbers
following the DOT code are the
Tire Identification 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.
(5) Tire Ply Material:The type
of cord and number of plies in
the sidewall and under the tread.
(6) 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, seeUniform Tire
Quality Grading0270.
