{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 headliner or pillar garnishtrim, overhead console, frontsensors, side impact sensors,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.
In addition, the vehicle may have apassenger sensing system for thefront outboard passenger position,which includes sensors that are partof the passenger seat. Thepassenger sensing system may notoperate properly if the original seattrim is replaced with non-GMcovers, upholstery, or trim; or withGM covers, upholstery, or trimdesigned for a different vehicle. Anyobject, such as an aftermarket seatheater or a comfort-enhancing pador device, installed under or on topof the seat fabric, could alsointerfere with the operation of thepassenger sensing system. Thiscould either prevent properdeployment of the passengerairbag(s) or prevent the passengersensing system from properly
turning off the passenger airbag(s).SeePassenger SensingSystem082.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0416for additionalimportant information.
If a snow plow is added to thevehicle, the airbags should still workproperly. The airbag systems weredesigned to work properly under awide range of conditions, includingsnow plowing with vehicles thathave the optional snow plow preppackage (RPO VYU). Do notchange or defeat the snow plow's“tripping mechanism.”If you do, itcan damage the snow plow and thevehicle, and may cause an airbagdeployment.
If you have to modify your vehiclebecause you have a disability andyou have questions about whetherthe modifications will affect thevehicle's airbag system, or if youhave questions about whether theairbag system will be affected if thevehicle is modified for any other

{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
Tire and Loading InformationLabel
Label Example
Avehicle-specificTireand
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 seeTires0397
andTire Pressure0405.
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 axles. See
“Certification/Tire Label”later in

occupants and cargo should
never exceed XXX kg or
XXX lbs." on your vehicle’s

for details regarding winter tireavailability and proper tire selection.Also, seeBuying New Tires0415.
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.
Low-Profile Tires
If the vehicle has P275/55R20,
P285/50R20, or P285/45R22
size tires, they are classified as
low-profile tires.
Caution
Low-profile tires are more
susceptible to damage from road
hazards or curb impact than
standard profile tires. Tire and/or
wheel assembly damage can
occur when coming into contact
with road hazards like potholes,
or sharp edged objects, or when
sliding into a curb. The warranty
does not cover this type of
damage. Keep tires set to the
correct inflation pressure and
when possible, avoid contact with
curbs, potholes, and other road
hazards.
All-Terrain Tires
This vehicle may have all-terraintires. These tires provide goodperformance on most road surfaces,weather conditions, and for off-roaddriving. SeeOff-Road Driving0251.
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. SeeTireInspection0411.
Tire Sidewall Labeling
Useful information about a tire is
molded into the sidewall. The
examples show a typical
passenger and light truck tire
sidewall.

Tire Designations
Tire Size
The examples show a typical
passenger vehicle and light
truck tire size.
Passenger (P-Metric) Tire
(1) Passenger (P-Metric) Tire:
The United States version of a
metric tire sizing system. The
letter P as the first character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association.
(2) Tire Width:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio:Atwo-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 tire illustration, it
would mean that the tire's
sidewall is 75 percent as high as
it is wide.
(4) Construction Code:Aletter
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.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Light Truck (LT-Metric) Tire
(1) Light Truck (LT-Metric)
Tire:The United States version
