Replacement blades come in different types and are
removed in different ways. Here is how to remove
the wiper blade:
1. Pull the windshield wiper arm connector away from
the windshield.
2. Squeeze the grooved areas on each side of the
blade and turn the blade assembly away from the

make sure the grooved areas are fully set in the
locked position.
For the proper type and size, seeMaintenance
Replacement Parts on page 6-17.
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. For additional information refer to the tire
manufacturer.
{CAUTION:
Poorly maintained and improperly used tires
are dangerous.
Overloading your vehicle’s tires can
cause overheating as a result of too
much exing. You could have an air-out
and a serious accident. SeeLoading the
Vehicle on page 4-34.
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 vehicle’s tires are
cold. SeeInflation - Tire Pressure on
page 5-76.
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 the tire’s tread is badly worn, or if your
vehicle’s tires have been damaged,
replace them.
5-67

20-Inch Tires
If your vehicle has the optional 20-inch
P275/55R20 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 or commercial
uses such as snow plowing. SeeOff-Road Driving
on page 4-13andAdding a Snow Plow or Similar
Equipment on page 4-40for additional information.
Notice:If the vehicle has low-prole tires,
they are more susceptible to damage from
road hazards or curb impact than standard
prole 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 vehicle
warranty does not cover this type of damage.
Keep tires set to the correct ination pressure
and, when possible avoid contact with curbs,
potholes, and other road hazards.
Tire Sidewall Labeling
Useful information about a tire is molded into the
sidewall. The following illustrations are examples
of a typical P-Metric and a LT-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.
Passenger (P-Metric) Tire
5-68

(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,
seeUniform Tire Quality Grading on page 5-89.
(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
seeInflation - Tire Pressure on page 5-76and
Loading the Vehicle on page 4-34.
