1996 BUICK CENTURY Owners Manual

If You Do Decide To Pull A Trailer
If you do, here are some important points:
e 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 kmh) 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 (88 km/h)) to
save wear on your vehicle’s parts.
Three important considerations have to do with weight:
the weight of the trailer,
the weight of the trailer tongue
and the total weight on your vehicle’s tires.
Weight of the Trailer
Your vehicle can tow normally up to 1,000 lbs. (450 kg).
If your vehicle has a
3.1 L 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 lbs. (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.

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 weight-carrying hitch, the trailer
tongue
(A) should weigh 10% of the total loaded trailer
weight
(€3). If you have a weight-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 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 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.
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
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.
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.
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 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 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 Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Buick dealer. The 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 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 lbs. (450 kg) and you have an automatic transaxle
with overdrive, you may prefer to drive in
THIRD (3)
instead of AUTOMATIC OVERDRIVE (@I). An
overdrive transmission is required if towing a trailer more
than
1,000 lbs. (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
2. Have someone place chocks under the trailer wheels.
PARK
(P) yet.
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).
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:
m Start your engine;
0 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.

Section 5 Problems on the Road
Here you’ll find what to do about some problems that
can occur on
the road.
Hazard Warning Flashers
Your hazard warning flashers let you warn others. They
also let police know
you have a problem. Your front and
rear turn signal lamps will flash on and off.
Press the button in to make your front and rear turn
signal lamps flash on and
off.

ProCarManuals.com

Your hazard warning flashers work no matter what
position your key is in and even if the key isn’t in.
To turn off the flashers, pull out on the collar. When
the hazard warning flashers are on, your
turn signals
won’t work.
Other Warning Devices
~f you carry reflective triangles, you can set one up
at the side of the road about
300 feet (100 m) behind
your vehicle.
Jump Starting
If your battery has run down, you may want to use
another vehicle and
some jumper cables to start your
Buick. But please use the following steps to do
it safely.
A CAUTION:
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
They contain gas that can explode or ignite.
They contain enough electricity to burn you.
If you don’t follow these steps exactly, some
or all
of these things can hurt you.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
