brake PONTIAC FIREBIRD 1997 Service Manual

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can
make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These
parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know
is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a
steep or long kill.
Coasting downhill! in NEUTRAL (N) or with
the ignition
off is dangerous. Your brakes will
have to do all the work of slowing
down. They
could get
so hot that they wouldn’t work well.
You would then have poor braking or even
none
going down a hill. You c’ould crash. Always have
your engine running and your vehicle in gear
when you! go downhill.

your engine assist your brakes on a steep
4-24

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.
Allow greater following distance on any
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.

road.

Towing a Trailer
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.
Pull
a trailer only if you have followed all the
steps in this section.
Ask your Pontiac dealer for
advice and information about towing
a trailer
with your vehicle.
NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this part, and see your Pontiac
dealer
for important information about towing a
trailer with your vehicle.
Your vehicle can tow a trailer if it is equipped with the
3800 and 5.7L engines and proper trailer towing
equipment.
To identify what the vehicle trailering capacity
is for your vehicle,
you should read the inforrnation 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.
4-32

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 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
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
monofid.e (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.
Before 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.
4-36

Driving On Grades Making Turns
I NOTICE:
Making very sharp turns while trailering could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal. Do
this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
Turn Signals When Towing a nailer
The green arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working. Reduce
speed and shift
to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes
so much
that they would get hot and
no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility
of engine and transmission overheating.
If you are towing a trailer and you have an automatic
transmission with overdrive, you may prefer to drive in
THIRD
(3) instead of AUTOMATIC OVERDRIVE (a)
(or, as you need to, a lower gear). Or, if you have a
manual transmission with FIFTH
(5) or SIXTH (6) gear
and you are towing a trailer, it’s better not to
use FIFTH
(5) or SIXTH (6) gear. Just drive in
FOURTH
(4) (drive in FIFTH (5) if you have a
six-speed manual transmission) or, as you need to,
a lower gear.

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.

A vehicle
can fall from a car car
adequately secured. This can cause a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before
it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks, They will damage drivetrain and
suspension components.
When your vehicle is being towed, have the ignition key
turned to the
OFF position. The steering wheel should
be clamped in a straight-ahead position, with a clamping
device designed for towing service.
Do not use the
vehicle’s steering column
lock for this. The transmission
should
be in NEUTRAL (N) and the parking
brake released.

Attach a separate safety chain around outboard end of
each lower control
arm.
