ng 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,
though. 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
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
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
graded
100. The relative performance of tires depends
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 Jn
road characteristics and climate.

Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel.. Sprays containing silicones or
waxes may cause annoying reflections
in the windshield
and
even make it difficult to see through the windshield
under certain conditions.
Care of Safety Belts
Keep belts clean and dry.
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate protection.
Clean safety belts only with mild soap and
lukewarm water.
~~~ ~
Glass
Glass should be cleaned often. GM Glass Cleaner (GM
Part
No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films. Don’t
use abrasive cleaners
on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped off later.
If
abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.
Cleaning the Outside of the
Windshield, Backglass and
Wiper Blades
If the windshield is not clear after using the windshield
washer, or
if the wiper blade chatters when running, wax
or other material may be on the blade or windshield.
Clean the outside of the windshield
with GM
Windshield Cleaner, Bon-Ami Powder@ (GM Part
No. 105001 1). The windshield is clean if beads do not
form when
you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked
in full-strength windshield washer solvent. Then rinse the
blade with water..
Wiper blades should be checked on a regular basis and
replaced when worn.

Maintenance Schedule
Short TripKity Definition
Follow the Short TripKity Maintenance Schedule if any
one
of these conditions is true for your vehicle:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such
as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons yo~l should follow this schedule if
you operate your vehicle under any of these conditions
is
that these conditions cause engine oil to break
down soonex

repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag covers, and
have them repaired or replaced, (The air bag system
does not need regular maintenance.)
