Backglass Wiper Blade Replacement 1. Lift the wiper blade assembly up and out of the park
rest position.
2. Pull the wiper blade assembly away from the
backglass. The backglass wiper blade will not
lock in a vertical position, so care should be used
when pulling it away from the vehicle.
3. Turn the wiper blade assembly, and pull it off of the
wiper arm. Hold the wiper arm in position and push
the blade away from the wiper arm. 4. Replace the wiper blade.
5. Return the wiper blade assembly to the park rest
position.

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 tires can cause
overheating as a result of too much
exing. You could have an air-out and
a serious accident. See Loading the
Vehicle on page 5-33 .
Underin ated 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 tires are cold. See
Inflation - Tire Pressure on page 6-62 .
CAUTION: (Continued) CAUTION: (Continued)
Overin ated 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 your tread is badly worn, or if your tires
have been damaged, replace them.
See High-Speed Operation on page 6-63 for
in ation pressure adjustment for high speed
driving.
22-Inch Tires If your vehicle has the optional 22-inch
P285/45R22 size tires, they are classi ed as
touring tires and are designed for on-road use.
The low-pro le, wide tread design is not
recommended for off-road driving. See Off-Road
Driving on page 5-13 , for additional information.

Tire Sidewall Labeling Useful information about a tire is molded into the
sidewall. The following illustration is an example
of a typical P-Metric tire sidewall.
(A) Tire Size :
The tire size code is a combination
of letters and numbers used to de ne 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
Speci cation) :
Original equipment tires designed
to GM’s speci c tire performance criteria have
a TPC speci cation code molded onto the sidewall.
GM’s TPC speci cations 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 Identi cation Number (TIN) :
The letters
and numbers following DOT code are the Tire
Identi cation 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 6-73 .Passenger (P-Metric) Tire
