Drive Systems
Four-Wheel Drive
If the vehicle has four-wheel drive,
you can send the 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 this section 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 the
vehicle's powertrain. Do not drive
on clean, dry pavement in
Four-Wheel Drive for extended
periods of time. Notice:
If the vehicle has
four-wheel drive and a different
size spare tire is installed, do not
drive in four-wheel drive until the
flat tire is repaired and/or
replaced. The vehicle could be
damaged and the repairs would
not be covered by the warranty.
Never use four-wheel drive when
a different size spare tire is
installed on the vehicle.
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 flat
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.
The transfer case buttons are
located to the right of the steering
wheel on the instrument panel.

Total Weight on the
Vehicle's Tires
Be sure the vehicle's tires are
inflated to the upper limit for cold
tires. These numbers can be found
on the Certification/Tire label
located at the bottom of the center
pillar on the driver's side of the
vehicle, or seeVehicle Load Limits
on page 9‑18. Make sure not to go
over the GVW limit for the vehicle,
or the GAWR, including the weight
of the trailer tongue. If using a
weight distributing hitch, make sure
not to go over the rear axle limit
before applying the weight
distribution spring bars.
Towing Equipment
Hitches
It is important to have the correct
hitch equipment. Crosswinds, large
trucks going by and rough roads are
a few reasons why the right hitch
is needed.
Weight-Distributing Hitches
and Weight Carrying Hitches
A step bumper hitch can be used for
trailers up to 907 kg (2,000 lbs) total
weight, and 90 kg (200 lbs) tongue
weight.
Notice: If a step-bumper hitch is
used, the bumper could be
damaged in sharp turns. Make
sure there is ample room when
turning to avoid contact between
the trailer and the bumper.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Instructions about safety chains
may be provided by the hitch
manufacturer or by the trailer
manufacturer. For trailers up to
907 kg (2,000 lbs) safety chains may
be attached to the attaching points
on the bumper. For heavier trailers,
follow the trailer or hitch
manufacturer's recommendation for
attaching safety chains. Always
leave just enough slack so the rig
can turn. Never allow safety chains
to drag on the ground.

Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer.
See the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{WARNING
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a result
of too much flexing. There
could be a blowout and a
serious crash. SeeVehicle
Load Limits on page 9‑18.
(Continued)
WARNING (Continued)
.Underinflated tires pose the
same danger as overloaded
tires. The resulting crash
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when
the tires are cold.
.Overinflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact—such as when
hitting a pothole. Keep tires at
the recommended pressure.
.Worn or old tires can cause a
crash. If the tread is badly
worn, replace them.
.Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.
(Continued)
WARNING (Continued)
.Improperly repaired tires can
cause a crash. Only the
dealer or an authorized tire
service center should repair,
replace, dismount, and
mount the tires.
.Do not spin the tires in
excess of 55 km/h (35 mph)
on slippery surfaces such
as snow, mud, ice, etc.
Excessive spinning may
cause the tires to explode.

The examples show a typical
passenger vehicle tire and a
compact spare tire sidewall.
Passenger (P‐Metric) Tire Example
(A) Tire Size:The tire size is a
combination of letters and
numbers used to define a
particular tire's width, height,

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 Identification
Number (TIN)
:The letters and
numbers following the DOT
(Department of Transportation) 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.
(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 10‑65.

emergency use when a regular
road tire has lost air and gone
flat. If the vehicle has a compact
spare tire, see
Compact Spare
Tire on page 10‑85 andIf a Tire
Goes Flat on page 10‑69.
(C) Tire Identification Number
(TIN)
:The letters and numbers
following the DOT (Department
of Transportation) code are the
Tire Identification Number (TIN).

manufactured. The TIN is
molded onto both sides of the
tire, although only one side may
have the date of manufacture.
(D) Maximum Cold Inflation
Load Limit
:Maximum load that
can be carried and the
maximum pressure needed to
support that load. (E) Tire Inflation
:

compact spare tire should be
inflated to 420 kPa (60 psi).
For more information on tire
pressure and inflation see
Tire
Pressure on page 10‑54.
(F) Tire Size
:A combination of
letters and numbers define a
tire's width, height, aspect ratio,
construction type, and service
description. The letter T as the
first character in the tire size
means the tire is for temporary
use only.
(G) 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.
