1995 PONTIAC FIREBIRD trailer

Three important considerations have to do with weight:
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,500 pounds (680 kg)
under normal driving conditions. It should never weigh
more than 1,000 pounds (450 kg) when driven on long
grades at high ambient temperatures. 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 capacity
weight of your vehicle. The capacity weight 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 will tow a trailer, you must subtract the tongue
load from your vehicle’s capacity weight because your
vehicle will be carrying that weight, too. Ske “Loading
Your Vehicle” in the Index for more information about
your vehicle’s maximum load capacity.

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 “wdght-distributing” hitch, the trailer
. tongue (A) should weigh 12% 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.
Total Weight on 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 Certifiidtion 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.
Hitclids
It’s imbortant 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 my 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 the
bumper.

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 pounds (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 instal, 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
thg 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.

Foliawing 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
Hoid the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the lek 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 Turns
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.
ProCarManuals.com

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. 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 driving
in THIRD
(D) instead of OVERDRIVE (or, as you need
to, a lower gear). Or, if you have
a manual transmission
with FIFTH (or SIXTH) gear and you are towing a
trailer, it’s better not to use FIFTH (or
SIXTH) gear.
Just drive in FOURTH (drive in FIFTH 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 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), 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;
0 Shift into a gear; and
0 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.

If No Steam Is Coming From Your Engine
If you
get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1.
2.
3.
If you have an air conditioner, turn it off.
Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
If you're in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (03)
or DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about ten minutes.
If the warning doesn't come-back on, you
can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there's still no sign of steam, you can idle the engine
for
two or three minutes while you're parked, to see if
the warning stops. But then, if you still have the
warning,
turn oflthe engine and get everyone out of the
vehide
until it cools down.
You may decide not to lift the hood but to get 'service
help right away.

Engine Oil Additives
Don’t add anything to your oil. Your Pontiac dealer is
ready to advise if you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop and go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
If any one of these is true for your vehicle, then you
need
to change your oil and filter every 3,000 miles
(5 000 km) or 3 months -- whichever comes first.
If none of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
comes first.
your car.
Engine Coolant Heater
An engine coolant heater can be a big help if you have
to park outside in very cold weather,
0 OF (- 1 8 O C) or
colder.
If your vehicle has this option, see “Engine
Coolant Heater” in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or
a local recycling
center for help.
