1997 PONTIAC FIREBIRD tire pressure

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.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
Remember: Anti-lock doesn’t change the time
you need
to get your foot up to the brake pedal or always decrease stopping distance.
If you
get too close to the vehicle in
front
of you, you won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal
down and let anti-lock work for you.
You may feel
the system working, or you may notice some noise,
but this is normal.
When your anti-lock system
is adjusting brake pressure
to help avoid a
braking skid, this light will come on.
See
“Low Traction Light” in the Index.
Traction Control System
(Option: LTI V8 Engine)
Your vehicle may have a traction control system that
limits wheel spin. This
is especially useful in slippery
road conditions. The system operates only
if it senses
that one or
both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the
system works the rear brakes and reduces engine power
(by closing the throttle and managing engine spark)
to limit wheel spin.

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 do not have 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.
Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddies or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips
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.
“Tires” in the Index.)
Have good tires with proper tread depth. (See
4-19

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,
Before 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 first 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.
Here are
some things you can check before a trip:

Two labels on your vehicle show how much weight it
may properly
carry. The Tire-Loading Information l'abel
found on 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.

The other label is the Certification label, found on the
rear edge of the driver's door. It tells you the gross
weight capacity of your vehicle,
called GVWR (Gross
Vehicle Weight Rating). The GVWR includes the weight
of the vehicle, all occupants, fuel and cargo. Never
exceed
the GVWR for your vehicle, or the Gross Axle
Weight Rating
(GAWR) for either the front or rear axle.
And, if you do have a heavy load, you should spread
it out. Don't ca more than 100 lbs. (45 kg) in your
rear area.

Compact Spare Tire
Although the compact spare tire 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 kPa).
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 speeds
up to 65 mph
(105 km/h) 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. (When the
compact spare
is used on the rear axle, see Notice
below.) 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. When the compact
spare is on the rear axle, the optional
traction control system will cycle and limit acceleration
for about the first 15 seconds of driving after each
engine start.
NOTICE:
If the compact spare is used as a rear tire, do not
drive faster than
50 mph (SO km/h). Damage to
the rear axle may occur
if the compact spare is
driven faster than 50 mph
(80 kmh).

It is recommended that the upper limit not exceed plus
0.4 degrees from the center of the bubble. Other drivers
may flash their high beams at you if your adjustment
is
much above plus 0.4 degrees.
Tires
Your new Pontiac comes with high-quality tires made
by a leading tire manufacturer.
If you ever have
questions about your tire warranty and where to obtain
service, see your Pontiac Warranty booklet for details.
Pa - - ly maintained and imp1 ,derly L,Ld tires
are dangerous.
Overloading your tires can cause overheating
as
a result of too much friction. You could have
an air-out and
a serious accident. See “Loading
Your Vehicle” in the Index.
CAUTION: (Continued) CAUTION:

Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on 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 1 mile ( 1.6 km).
If you’ll be driving at speeds higher than
100 mph
(160 kdh) where it is legal, raise the cold inflation
pressure
of each tire to 35 psi (240 kPa). When you
end this very high-speed driving, reduce the
cold
inflation pressures to those listed on the Tire-Loading
Information label.
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 the following:
Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
0 B,ad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
0 Unusual wear
0 Bad handling
Rough ride
0 Needless damage from road hazards.

When to Check
Check your tires once a month or more.
uon’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may
look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, 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.
If you don’t have P245/5OZR16 or P275/40ZR17
Goodyear Eagle GS-C tires, use the rotation pattern
shown above for your tires.
