Backglass Wiper Blade Replacement
See "Windshield Wiper Blade Replacement" in this
section for instructions
on how to change the backglass
wiper blade. The backglass wiper blade
will not lock in
a vertical position like the windshield wiper blade. so
care should be used when pulling it away from
the vehicle.
Tires
Y~LI~ new vehicle comes with high-quality tires made by
a leading tire nnanufacturer.
If you ever have questions
about your tire warranty and where to obtain service, see
your warranty booklet for details.

A CAUTION:
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating
as a result of too much friction.
You could have an air-out and a serious
accident. See “1,oading Your Vehicle” in
the Index.
Underinflated 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.
Overinflated 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.
Inflation -- Tire Pressure
The Cel-tification/Tire label. which is 011 the driver‘s
door edge, above the door latch. shows the correct
inflation
pressures for your tires when they’re cold.
“Cold“ lneans your vehicle has been sitting for at least
three hours or driven no more than 1 mile ( 1 .6 km).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not.
If‘ your tires
don’t have enough air (underinflation), you can
get the following:
Too much flexing
Too much heat
0 Tire overloading
Bad wear
0 Bad handling
0 Bad fuel economy.
NOTICE: (Continued)
6-4 1

I NOTICE: (Continued) I
If your tires have too much air (overinflation),
you
can get the following:
0 Unusual wear
0 Bad handling
0 Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or n101-e. Also. check the
tire pressure
of the spare tire.
I! you have a compact spare tire. it should be at 60 psi
(420
k Pa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can't tell
if your tires are properly inflated
simply
by looking at thcm. Radial tires may look
properly inflated even when they're underintlatecl.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks
by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires s11o111d be rotated every 6,000 to 8,000 miles
( IO 000 to 13 000 km). Any time you notice unusual
we;^. rotate your tires as soon as possible and check
wheel alignment.
Also check for damaged tires or
wheels. See "When 1t.s Time for New Tires" and
"Wheel Replacement" later
in this section for
more information.
Thc purpose
of' reg~~lar rotation is to achieve more
uniform wear
fur all tires on the vehicle. The first
rotation
is thu most important. See "Schecluled
Maintenance Services"
in the Index for scheduled
rotation intervals.

6-42

I1
If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certificatioflire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque’’ in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come
off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle.
In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt
off. (See
“Changing a Flat Tire” in the Index.)
6-43

When It's Time for New Tires
One way to tell when it's
time for new tires is to
check the treadwear
indicators, which will
appear
when YOLII- tires have
only 1/16 inch ( I .6 mm) or
less
of tread remaining.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
around the tire.
You can see cord or hbric showing through the
tire's rubber.
The tread or sidewall is cracked. cut or snagged deep
enough
to show cord or fabric.
The tire has a bump. bulge or split.
The tire has a puncture, cut or other damage that
can't be repaired well because of the size or location
of the darnage.
Buying New Tires
To find out what kind ;m.l size of tires you need, look at
the CertificatiodTire label.
The tires installed on your vehicle when
it was new had
a Tire Performance Criteria Specification (TPC Spec)
number
on each tire's sidewall. When you get new tires,
your vehicle
will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction. ride and other things during normal service
on
your vehicle. If your tires have an all-season tread
design, the
TPC number will be followed by an "MS"
(for mud and snow).
If you ever replace your tires with those not hktving a
TPC Spec number. make sure [hey are the same size.
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
c get ones with that same TPC Spec number. That way
6-44

Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have
a crash.
Using tires
of different sizes may also cause
damage to
your vehicle. Be sure to use the same
size and type tires
on all wheels.
It’s all right to drive with your compact spare
(if you have one). It was developed for
use on
your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed
by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear. traction and temperature performance. (This
applies only to vehicles
sold in the United States.) The
grades are molded on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system does not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal
rim diameters of 10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary
with respect to these
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
c Urades, they rnust also conform to Federal safety
Treadwear
The treadwear grade is a comparative rating based
on
the wear rate of the tire when tested under controlled
conditions on
a specified government test course. For
example.
a tire graded 150 would wear one and a half
( 1 1/2) times as well on the government course as a tire
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and clilnate.
