BUICK CENTURY 1993 Owners Manual

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 t\
o
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 fit, 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 nrns
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 Mler
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 Mh) to reduce the possibility of
engine and transaxle overheating.
If you are towing a trailer that weighs more than 1,OOO
pounds (450 kg) and you have an automatic transaxle
with Overdrive, you may prefer
to drive in “D” instead
of Overdrive.
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”
2. Have someone place chocks under the trailer wheels. (Park) 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
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
brake, and then shift to
“P” (Park).
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.

you should know. Positive

negative
(-) will go to negative (-) or a metal engine
part. Don’t connect

would damage the battery and maybe other
parts, too.

Don't let the other end
touch anything until the
next step. The other end of
the negative cable
doesn't
go to the dead battery. It
goes to a heavy unpainted
metal part on the engine of

battery.
9. Attach the cable at least 18 inches (45 cm) away from
the dead battery, but not near engine parts that move.
The electrical connection is just
as good there, but
the chance
of sparks getting back to the battery is
much less.
