1995 PONTIAC GRAND-AM tire pressure

Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out in
front of you.
You slam on the brakes. Here’s what happens with ABS.
The anti-lock system can change the brake pressure faster
than
any driver could. The computer is programmed to
make the most of available tire and road conditions.
You can steer around the obstacle while braking hard.
A computer senses that wheels are slowing down. If one you brake, your computer keeps receiving updates on

Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road
is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn’t happen often. But it can if your
tires haven’t much tread or if the pressure in one or
more is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles, or other vehicles, and raindrops “dimple” the
water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning. The
best advice
is to slow down when it is raining.
Some Other Rainy Weather Tips
0 Turn on your low-beam headlamps -- not just your
parking lamps
-- to help make you more visible to
others.
0 Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared to have your view restricted
by road spray.
0 Have good tires with proper tread depth. (See
“Tires” in the Index.)

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane
well in advance. If you miss your exit do not, under
any circumstances, stop and back up. Drive on to the
next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to
think you are going
slower than you actually
are.
Befo’re Leaving on a Long Trip
Make sure you’re ready. Try to be well .rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that fiist part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have it done before starting out.
Of course,
you’ll find experienced and able service experts in
Pontiac dealerships all across North America. They’ll be
ready and willing to help if you need
it.

Tires: They are vitally important to a safe,

Are the tires all inflated to the

Two labels on your vehicle show how much weight it
may properly
carry. The Tire-Loading Information label
found on the rear edge of the driver's door tells
you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle.
It also gives you
important information about the number
of people that
can be in
your vehicle and the total weight that you can
carry. This weight is called the Vehicle Capacity Weight
and includes the weight of all occupants, cargo, and all
nonfactory-installed options.

If you’re using a “dead-weight” hitch, the trailer tongue
(A) should weigh 10% of the total loaded trailer weight
(B).
If you have a “weight-distributing” hitch, the trailer
tongue
(A) should weigh 12% of the total loaded trailer
weight
(E).
After you’ve loaded your trailer, weigh the trailer and
then the tongue, separately, to
see if the weights are
proper. If they aren’t, you may be able to get them right
simply by moving some items around in the trailer.
Total Weight an Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the
recommended pressure for cold tires. You’ll find these
numbers on the Certification label at the
rear edge of the
driver’s door or see “Loading
Your Vehicle” in the
Index. Then be sure you don’t go over the
GVW limit
for your vehicle, including the weight of the trailer
tongue.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going
by, and rough roads are a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
0
Will you have to make any holes in the body of your
vehicle when you install a trailer hitch? If you do,
then be sure
to seal the holes later when you remove
the hitch. If you don’t seal them, deadly carbon
monoxide
(CO) from your exhaust can get into your
vehicle (see “Carbon Monoxide” in the Index).
Dirt
and water can, too.
The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them. Use only a
frame-mounted hitch that does not attach to
$he
bumper.

Compact Spare Tire
Although the compact spare was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 Wa). After installing the compact spare on your
vehicle, you should stop as soon as possible and make
sure your spare tire is correctly inflated. The compact
spare is made to perform well at posted speed limits for
distances up to
3,000 miles (5 000 km), so you can
finish your trip and have your full-size tire repaired or
replaced where you want. Of course, it’s best to replace
your spare with a full-size tire as soon as you can. Your
spare will last longer and be in good shape in case you
need it again.
I NOTICE:
Don’t take your compact spare through an
automatic car wash with guide rails. The
compact spare can get caught on the rails. That
can damage the tire and wheel, and maybe other
parts of your vehicle.
Don’t use your compact spare on some other vehicle.
And don’t mix your compact spare or wheel with other
wheels or tires. They won’t fit. Keep your spare and its
wheel together.
NOTICE:
Tire chains won’t fit your compact spare. Using
them
will damage your vehicle and destroy the
chains too. Don’t use tire chains on your compact
spare.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the rear
edge of the driver’s door shows the correct inflation
pressures for your tires, when they’re cold. “Cold”
means your vehicle has been sitting for at least three
hours or driven no more than a mile.
I 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:
0 Too much flexing
0 Too much heat
Tire overloading
0 Bad wear
0 Bad handling
Bad fuel economy.
(Continued)
1 NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get:
0 Unusual wear
0 Bad handling
0 Rough ride
0 Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 Wa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will not tell you the
pressure, especially if you have radial tires
-- which
may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure to put them back
on. They help prevent leaks by keeping out dirt and
moisture.

Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(1 0 000 to 13 000 km) for any signs of unusual wear. If
unusual wear is present, rotate your tires as soon as
possible
and check wheel alignment. Also check for
damaged tires or wheels. See “When it’s Time for New
Tires”
and “Wheel Replacement” later in this section for
more information.
The purpose of regular rotation is to achieve more uniform
wear for all tires on the vehicle. The first rotation is the
most important.
See “Scheduled Maintenance Services” in
the Index for scheduled rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the
Index.
