1994 BUICK PARK AVENUE towing

Your car can tow a trailer if it is equipped with the 3800
(L27) engine or (L67) Supercharged engine and 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 section. 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, transaxle,
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
If you do, here are some important points.
There are many different laws 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 if your trailer will
weigh
2,000 pounds (900 kg) or less. You should
always use a sway control if your trailer will weigh
more than
2,000 pounds (900 kg).
You can ask a hitch dealer about sway controls.
Don’t tow a trailer at all during the first 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
0 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.
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
1,000 pounds (450 kg),
unless you have the optional
3,000 pound (1350 kg)
trailer towing package. 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.

advice, or you can write us at Buick Motor Division,

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. See “Loading
Your Vehicle” in the Index for more information about
your vehicle’s maximum load capacity.
A
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 “weight-distributing” hitch, the trailer
tongue (A) should weigh
12% of the total loaded trailer
weight
(B).

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 you 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
so
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform,
safety chains, electrical connector, lights, 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 lights 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 Turns
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 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 lights
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.
Your vehicle has bulb warning lights. When you plug
trailer lights into your vehicle’s lighting system, its bulb
warning lights may not
let you know if one of your
lights goes out.
So, when you have trailer lights plugged
in, be sure to check your vehicle and trailer lights from
time to time to be sure they’re all working. Once you
disconnect the trailer lights, the bulb warning lights
again can tell you
if one of your vehicle lights is out.
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 to “D or 3” (Drive)
and reduce your speed to around
45 mph (70 km/h) to
reduce the possibility of engine and transaxle
overheating.
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 “P”
(Park) yet.
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 the shift to
“P” (Park).
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 transaxle fluid (don’t overfill),
engine oil, 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.

Towing Your Park Avenue
Try to have a GM dealer or a professional towing
service tow your Buick. The usual towing equipment is
a sling-type
(A), wheel-lift (B) or car carrier (C) tow
truck.

If your vehicle has been changed or modified since it
was factory-new by adding after market items like fog
lamps, aero skirting, or special tires and wheels, these
instructions and illustrations may not be correct.
Before you do anything, turn on the hazard warning
flashers.
When you call, tell the towing service:
That your vehicle has front-wheel drive.
0 The make, model, and year of your vehicle.
Whether you can still move the shift lever.
0 If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains detailed towing
instructions and illustrations. The operator may want to
see them.

When your vehicle is being towed, have the ignition key off.
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
transaxle should be
in Neutral and the parking brake released.
Don’t have your vehicle towed on the front wheels,
unless you must.
If the vehicle must be towed on the
front wheels, don’t go more than
55 mph (88 km/h) or
farther than
500 miles (800 km) or your transaxle will
be damaged. If these limits must be exceeded, then the
front wheels have
to be supported on a dolly.
