1994 BUICK CENTURY towing

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 on!y
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 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.
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:
Weight of the Trailer
Your vehicle can tow normally up to 1,000 pounds
(450kg). If your vehicle has a
3100 V6 engine with a
four-speed automatic transaxle and is equipped with the
optional heavy-duty engine cooling system,
it can tow
up to 2,000 pounds (900 kg).
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.

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. Always leave just enough slack
so you can turn with your rig. And, never allow safety
chains
to drag on the ground.
Trailer Brakes
Does your trailer have its own brakes? 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
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.
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 transaxle overheating.
If you are towing a trailer that weighs more than 1,000
pounds (450
kg) and you have an automatic transaxle
with Overdrive, you may prefer to drive in “D” instead
of Overdrive.
An overdrive transmission is required if
towing a trailer more than 1,000 pounds (450 kg).

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 then 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;
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 transaxle fluid (don’t overfill),
engine oil, belt, 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 Buick
Try to have a GM dealer or a professional towing
service tow your Buick. The usual towing equipment is
a sling-type
(A) or 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 aftermarket 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:
0 That your vehicle has front-wheel drive.
0 The make, model, and year of your vehicle.
0 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.

ProCarManuals.com

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 35 mph (56 km/h) or
farther than
50 miles (80 km) or your transaxle will be
damaged. If these limits must be exceeded, then the
front wheels have to be supported on a dolly.
Front Towing Hookups
Before hooking up to a tow truck, be sure to read all the
information in “Towing Your Buick” earlier in this part.
1. Attach T-hook chains behind the front wheels into
the bottom
of the floor pan on both sides.
