1998 PONTIAC FIREBIRD Owners Manual

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.

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.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total or
gross
weight of your vehicle. The Gross Vehicle Weight
(GVW) includes the curb weight of the vehicle, any
cargo you may carry in it,
and the people who will be
riding
in the vehicle. And if you tow a trailer, you must
add the tongue load to the
GVW because your vehicle
will
be carrying that weight, too. See “Loading Your
Vehicle” in the Index for more information about your
vehicle’s maximum load capacity.
A B
If you’re using a weight-carrying hitch, the trailer
tongue
(A) should weigh 10 percent of the total loaded
trailer weight
(B). If you have a weight-distributing
hitch, the trailer tongue
(A) should weigh 12 percent of
the total loaded trailer weight
(B).
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.
4-34

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.
4-35

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.

Making &rns
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.
lbrn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Pontiac dealer. 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.
Driving On Grades
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
(D) instead of AUTOMATIC OVERDRIVE @
(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. Just drive in
FOURTH
(4) gear (or drive in FIFTH (5) if you have a
six-speed manual transmission) or, as
you need
to, a lower gear.
4-37

0 Shift into a gear; and
0 Release the parking brake.
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 transmission.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks 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) for an
automatic transmission, 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:
0 Start your engine;
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, drive 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
this information before you start your trip.
Check periodically to
see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.
