1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into
a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
4. After you’ve used the coolant heater, be sure to
store the cord as it
was before to keep it away
from moving engine parts. If
you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind
of oil you have, and some other things. Instead of
trying to list everything here; we ask that you contact
your Buick dealer
in the area where you’ll be parking
your vehicle. The dealer can give
you the best advice for
that particular area.

NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat.
You may have to
replace them, and you could also damage other
parts
of vour vehicle.
If you are towing a trailer and are parking on any hill,
see “Towing a Trailer” in the Index. That section shows
what to do first to keep the trailer from moving.

It can be dangerous to get out of your vehicle if‘
the shift lever is not fully in PARK (P) with the
parking brake
firmly set. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly.
You or others could be
injured.
To be sure your vehicle won’t move, even
when you’re on fairly level ground, use the steps
that
follow. If you’re pulling a trailer, see
“Towing
a Trailer” in the Index.

Leaving Your Vehicle With the
Engine
Running
A CAUTION
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move
suddenly if the shift lever
is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don’t leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you’ve moved the shift lever into the PARK (P)
position, hold the regular brake pedal down. Then, see if
you can move the shift lever away from PARK (P)
without first pulling it toward
you. If you can, it means
that the shift lever wasn’t fully locked into PARK
(P).
Note: If for some reason you leave your vehicle running
and
it is not in PARK (P) and the parking brake is
applied, your doors will automatically lock when you
close the door.
Torque Lock
If you are parking on a hill and you don’t shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. You may find it difficult to pull the shift
lever
out of PARK (P). This is called “torque lock.” To
prevent torque lock, set the parking brake and then shift
into PARK (P) properly before
you leave the driver’s
seat.
To find out how, see “Shifting Into PARK (P)” in
the Index.
When you are ready
to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours
a little uphill to take some of the
pressure from the transaxle,
so you can pull the shift
lever out of PARK (P).

Anti-Lock Brake S A
LOW
TRACTION
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the anti-lock brakg system active light will come on.
Slippery road conditions may exist if this light comes
on,
so adjust your driving accordingly. The light will
stay
on for a few seconds after the system stops
adjusting brake pressure.
The anti-lock brake system active light also comes on
briefly when
you turn the ignition key to RUN. If the
light doesn’t come
on then, have it fixed so it will be
there to tell you when the system
is active.
Engine Coolant Temperature
Warning
Light
This warning light is
designed to tell you that
your engine coolant has
overheated or your radiator
cooling fan is not working.
If you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and turn the engine off as soon as possible.
The section “Problems on the Road,” in this manual
explains what to do. See “Engine Overheating” in
the Index.

pointer moves into the red area, your engine is too hot!
That reading means the same thing
as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, and stop your
engine as soon as possible.

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).

Engine Overheating
You will find a coolant temperature gage or the
warning light about a hot engine on
your Buick’s
instrument panel.
If St1 .-m Is 1 - - ng Fro Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn
it off and get everyone away
from the vehicle until
it cools down. Wait until
there is no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
