1994 GMC SIERRA belt

Dual lire Operation
If your vehicle has dual rear wheels, the outer tire will usually wear faster
than the inner tire. Your tires will wear more evenly and last longer
if you
rotate the tires periodically. If you’re going to be doing a lot of driving on
high-crown roads,
you can reduce tire wear by adding 5 psi (35 kPa) to the
tire pressure in the outer tires. Be sure to return to the recommended
pressures when
no longer driving under those conditions.
Buying New Tires
To find out what kind and size of tires you need, look at the
CertificationRire 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 a
“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.

Care of Safety Belts
Keep belts clean and dry.
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 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.
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
