One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less
of tread remaining.
You need a new tire
if any of the following statements
are true:
You can see the indicators at three or more places
You can see cord or fabric showing through the
The tread or sidewall is cracked, cut or snaggea
around the tire.
tire’s rubber. 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 damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information 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, get ones with that same TPC Spec number. That way
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 having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.

Downloaded from www.Manualslib.com manuals search engine Cleaning Glass Surfaces
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 on
interior glass.
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 and Wiper Blades
If the windshield is not clear after using the
windshield washer, or
if the wiper blade chatters
when running, wax, sap or other material may’ be
on the blade or windshield.
Clean the outside
of the windshield with GM
Windshield Cleaner, Bon Ami@ Powder (non-scratching
glass cleaning powder),
GM Part No. 105001 1. The
windshield
is clean if beads do not form when you rinse
it with water. Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with
a cloth soaked in full-strength windshield
washer solvent. Then rinse the blade with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. (See “Recommended
Fluids and Lubricants” in the Maintenance Schedule
booklet.)
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep
it clean by washing
it often with lukewarm or cold water.
