Four-Wheel Drive
If your vehicle has four-wheel drive, you can send
your engine’s driving power to all four wheels for
extra traction. To get the best performance out of
four-wheel drive, you must be familiar with its
operation. Read the part that follows before using
four-wheel drive. You should use two-wheel-drive
high for most normal driving conditions.
Notice:Driving on clean, dry pavement in
four-wheel drive for an extended period of
time can cause premature wear on your
vehicle’s powertrain. Do not drive on clean,
dry pavement in Four-Wheel Drive for
extended periods of time.
Notice:If your vehicle has four-wheel drive
and the compact spare tire is installed on
your vehicle, do not drive in four-wheel drive
until you can have your at tire repaired and/or
replaced. You could damage your 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 your vehicle.The transfer case buttons are located to the right
of the steering wheel on the instrument panel.

The airbag system is designed to work properly
under a wide range of conditions, including off-road
usage. Observe safe driving speeds, especially
on rough terrain. As always, wear your safety belt.
Off-road driving can be great fun. But it does
have some denite hazards. The greatest of
these is the terrain itself.
“Off-roading” means you have left the great
North American road system behind. Traffic lanes
are not marked. Curves are not banked. There
are no road signs. Surfaces can be slippery, rough,
uphill, or downhill. In short, you have gone right
back to nature.
Off-road driving involves some new skills. And
that is why it is very important that you read
this guide. You will nd many driving tips and
suggestions. These will help make your off-road
driving safer and more enjoyable.Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary
maintenance and service work done. Check to
make sure all underbody shields, if the vehicle
has them, are properly attached. Be sure you
read all the information about your four-wheel-drive
vehicle in this manual. Is there enough fuel?
Is the spare tire fully inated? Are the uid levels
up where they should be? What are the local
laws that apply to off-roading where you will be
driving? If you do not know, you should check
with law enforcement people in the area. Will you
be on someone’s private land? If so, be sure
to get the necessary permission.

Tire Sidewall Labeling
Useful information about a tire is molded into
its sidewall. The examples below show a typical
passenger vehicle tire and a compact spare
tire sidewall.(A) Tire Size:The tire size 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.
Passenger Vehicle Tire Example
378

(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 seeUniform Tire Quality
Grading on page 395.
(G) Maximum Cold Ination Load Limit:
Maximum load that can be carried and the
maximum pressure needed to support that load.(A) Temporary Use Only:The compact spare
tire or temporary use tire has a tread life of
approximately 3,000 miles (5 000 km) and should
not be driven at speeds over 65 mph (105 km/h).
The compact spare tire is for emergency use
when a regular road tire has lost air and gone at.
See “Compact Spare Tire” underSpare Tire on
page 420for additional information.
(B) Tire Ply Material:The type of cord and number
of plies in the sidewall and under the tread.

(C) Tire Identication Number (TIN):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.
(D) Maximum Cold Ination Load Limit:
Maximum load that can be carried and the
maximum pressure needed to support that load.
(E) Tire Ination:The temporary use tire or
compact spare tire should be inated to 60 psi
(420 kPa). For more information on tire pressure
and ination seeInation - Tire Pressure on
page 384.
(F) Tire Size:A combination of letters and
numbers dene a tire’s width, height, aspect
ratio, construction type and service description.
The letter T as the rst character in the tire
size means the tire is for temporary use only.
(G) 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.Tire Size
The following illustration shows an example of a
typical passenger vehicle tire size.
(A) 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 70,
as shown in item C of the illustration, it would mean
that the tire’s sidewall is 70 percent as high as
it is wide.

Ination - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-ination or over-ination is all right.
It is not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazardsA vehicle specic Tire and Loading Information
label is attached to your vehicle. This label shows
your vehicle’s original equipment tires and the
correct ination pressures for your tires when they
are cold. The recommended cold tire ination
pressure, shown on the label, is the minimum
amount of air pressure needed to support
your vehicle’s maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example
of the Tire and Loading Information label,
seeLoading Your Vehicle on page 293. How
you load your vehicle affects vehicle handling
and ride comfort. Never load your vehicle
with more weight than it was designed to carry.
When to Check
Check your tires once a month or more.
Also check the tire pressure of the spare tire.
If your vehicle has a compact spare tire, it
should be at 60 psi (420 kPa). SeeSpare Tire
on page 420for additional information.

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 ination 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.
Tire Pressure Monitor System
Your vehicle has a Tire Pressure Monitor
System (TPMS). This system uses radio and
sensor technology to check tire pressure levels.
TPMS sensors are mounted onto each tire
and wheel assembly on your vehicle, except
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 will illuminate the low tire pressure
warning light located in the instrument panel
cluster, and at the same time display the LOW
TIRE warning message on the Driver Information
Center (DIC). The low tire pressure warning
light and the LOW TIRE warning message appear
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 Controls and Displays
on page 198andDIC Warnings and Messages
on page 202.
