Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill.
If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and
the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual transmiss’ion.
2. Have someone place chocks under the trailer wheels.
3, When the wheel C~OGBS are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes, Then apply your parking
brake, and then shift to
PARK (P), or REVERSE (R)
for a manual transmission.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation
are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belts, cooling system
and brake adjustment. Each
of these is covered in this
manual, and the Index will help you find them quickly,
If you’re trailering, it’s a good idea to review these
sections before
you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

Here you will find information about the care of your Pontiac. This section begins with service and fuel information,
and then it shows how to check imDortant fluid and lubricant levels. There is also technical information about your I
vehicle, and a part devoted to its appearance care.

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 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:
0 You can see the indicators at three or more places
around the tire.
0 You can see cord or fabric showing through the
tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged deep
enough to show cord
or fabric.
0 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.
Mixing tires could cause you to lose control while
driving.
If you mix tires of dif€erent sizes or types
(radi,al
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 0n 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 lirnited-pro'duction 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 gov'esnrnent 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 in
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 sal belts. 1 v'ou 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 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.
