tires PONTIAC FIREBIRD 1998 User Guide

Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and a
couple
of reflective warning triangles. And, if you will
be driving under severe conditions, include a
smdi bag
of sand, a piece of old carpet or a couple of burlap bags
to help provide traction. Be sure
you properly secure
these items
in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have
good traction.
However, if there is snow or ice between your tires and
the road, you can have
a very slippery situation. You’ll
have
a lot less traction or “grip” and will need to be
very careful.
4-26

What’s the worst time for this? “Wet ice.” Very cold
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all. You can get wet ice when it’s about
freezing
(32°F; 0” C) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
If you have traction control, keep the system on. It will
improve your ability to accelerate when driving on a slippery road. Even though your vehicle has a traction
control system, you’ll want to slow down and adjust
your driving to the road conditions. See “Traction
Control System”
in the Index.
If you don’t have the traction control system, accelerate
gently. Try not to break the fragile traction. If you
accelerate too fast, the drive wheels
will spin and polish
the surface under the tires even more. Your
anti-lock brakes improve your vehicle’s stability
when you make a hard stop on a slippery road. Even
though you have the anti-lock braking system, you’ll
want to begin stopping sooner than you would
on dry
pavement. See “Anti-Lock” in the Index.
0 Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On
an
otherwise clear road, ice patches may appear in
shaded areas where the sun can’t reach: around
clumps of trees, behind buildings
or under bridges.
Sometimes the surface of a curve or an overpass may
remain icy when the surrounding roads are clear. If
you see a patch of ice ahead of you, brake before you
are on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.

'q s Manual for tire pressure needed at
l~lH(100 mph) or higher speeds, where legal, and for additional tire information
Two labels on your vehicle show how much weight it
may properly
carry. The Tire-Loading Information label
found on the rear edge of 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 carry more than
100 lbs. (45 kg) in your
rear area.

Towing a Trailer
A CAUTION:
F-
If you don’t use the correct equipment and drive
properly, you can lose control when you
pull a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
You may also damage your vehicle; the resulting
repairs would not be covered
by your warranty.
Pull a trailer
only if you have followed all the
steps in this section.
Ask your dealer for advice
and information about towing a trailer with
your vehicle.
Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what the
vehicle trailering capacity
is for your vehicle, you
should read the information in “Weight of the Trailer”
that appears later
in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and it has to be used properly.
That’s the reason for
this part. In it are many
time-tested, important trailering tips and
safety rules.
Many
of these are important for your safety and that of
your passengers. So please read this section carefully
before
you pull a trailer.
Load-pulling components such
as the engine,
transmission, rear axle, wheel assemblies
and tires are
forced to work harder against the drag
of the added
weight.
The engine is required to operate at relatively
higher speeds and under greater loads, generating extra
heat. What’s more,
the trailer adds considerably to wind
resistance, increasing the pulling requirements.

If You Do Decide To Pull A Trailer

There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you’ll be driving. A good source for this
information can be state or provincial police.
Consider using a sway control. You
can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during the first
1,000 miles
(1 600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first
500 miles (800 km) that you
tow a trailer, don’t drive over
50 mph (80 km/h) and
don’t make
starts at full throttle. This helps your
engine and other parts
of your vehicle wear in at the
heavier loads.
0 Obey speed limit restrictions when towing a trailer.
Don’t
drive faster than the maximum posted speed
for trailers (or no more than
55 mph (90 km/h)) to
save wear on your vehicle’s parts.
Three important considerations have to do with weight:
0 the weight of the trailer,
the weight of the trailer tongue
and the total weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
1,500 lbs. (680 kg)
under normal driving conditions. It should never weigh
more than
1,000 lbs. (450 kg) when driven on long
grades at high ambient temperatures (Above
90” F
(32” C). But even that can be too heavy.
It depends on how you plan to use your
rig. For
example, speed, altitude, road grades, outside
temperature
and how much your vehicle is used to
pull a trailer
are all important. And, it can also depend
on any special equipment that you have on your vehicle.
4-33

Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the upper
limit 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 The rear bumper on your vehicle is not intended for
hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only
a frame-mounted
hitch that does not attach to the bumper.
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.
Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer
so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer’s recommendation for attaching safety
chains and do not attach them to the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 lbs. (450 kg)
loaded, then it needs its own brakes -- and they must
be adequate. Be sure to read and follow the instructions
for the trailer brakes
so you’ll be able to install, adjust
and maintain them properly. Because you have anti-lock
brakes, do not try to tap into your vehicle’s brake
system. If you do, both brake systems won’t work
well, or at all.

Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Befm setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving
is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment.
If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets
you check your
electrical connection at the
same time.
During
your trip, check occasionally to be sure that the
load is secure,
and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden
turns.
Passing
You’ll need more passing distance up ahead when
you’re towing
a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond
the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then,
to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to
the right. Always back up slowly and, if
possible, have someone guide you.

Towing Your Vehicle
Try to have a GM dealer or a professional towing
service tow your vehicle.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
instructions may not be correct.
Before
you do anything, turn on the hazard
warning flashers.

If a Tire Goes Flat Changing a Flat Tire
It’s unusual
for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the
flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to
go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely. If
a tire goes flat, avoid further
tire and wheel damage
by driving slowly to a level place.
Turn on your hazard
warning flashers.
I
A CAUTION:
Changing a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people. You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift lever in
PARK (P), or shift a manual transmission to
FIRST (1) or REVERSE (R).
3. I’urn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other
side of the
vehicle, at the opposite end.
5-27

Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together. If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to
spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck,
NOTICE: but you must use caution.
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.
A CAUTION:
m
If you let your tires spin at high speed, they can
explode, and you or others could
be injured.
And, the transmission or other parts
of the
vehicle can overheat. That could cause an
engine compartment fire or other damage.
When you’re stuck, spin the wheels
as little as
possible. Don’t spin the wheels above
35 mph
(55 kmh) as shown on the speedometer.
