Engine Coolant Heater (Option)
In very cold weather,
0°F (-1 8°C) or colder,
the engine coolant
heater can help. You’ll
get easier starting and
better fuel economy
during engine warm-up.
Usually, the coolant heater should be plugged
in a
minimum of four hours prior to starting your vehicle.
To Use the Coolant Heater
I. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
Plugging the cord into an ungrounded 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.

SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND
(2) on hills.
It can help control your speed
as you go down steep
mountain roads, but then you would
also want to use
your brakes
off and on.
NOTICE:
Don’t drive in SECOND (2) for more than
25 miles (41 km), or at speeds over 55 mph
(88 km/h), or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE
(@) or
THIRD (3) as much as possible.
Don’t shift into SECOND
(2) unless you are
going slower than
65 mph (105 km/h), or you can
damage your engine. FIRST
(1): This
position gives you even more power
(but lower
fuel economy) than SECOND (2). You can
use it on very steep hills, or in deep snow or mud. If the
shift lever
is put in FIRST ( 1 ), the transaxle won’t shift
into first gear
until the vehicle is going slowly enough.
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against
a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into PARK
(P)
to hold your vehicle in position on a hill.

Leaving Your Vehicle With the Engine
Running
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 (or, if you have the
console shift lever, without first pushing the button). If
you can, it means that the shift lever wasn’t fully locked
into PARK
(P).
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)
bqfore 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 System Active Light
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the anti-lock brake system
active light will come on.
Engine Coolant Temperature Light
-
TEMP
This light tells you that your
engine coolant has
overheated or your radiator
cooling fan
is not working.
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. If
you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine
as soon as possible.
In “Problems
on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

Engine Coolant Temperature Gage

TEMPERATURE
You have a gage that shows
the engine coolant temperature. If the gage
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, stop your
vehicle and turn
off the engine as soon as possible.
In “Problems on the Road,”
this manual shows what to
do. See “Engine Overheating” in
the Index.
Low Coolant Warning Light
LOW
COOLANT
If this light comes on, your
system is low on coolant
and the engine may
overheat. See “Engine
Coolant” in ‘the Index and
have your vehicle serviced as soon as you can.

Making mrns
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.
nrn 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 green arrows on your
instrument pariel 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 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 lbs. (450 kg), you may prefer to drive in
THIRD
(3) instead of AUTOMATIC OVERDRIVE (a)
(or, as you need to, a lower gear).
ProCarManuals.com

Engine Overheating
YOU will find a coolant temperature gage and a warning
light about a hot engine on your instrument panel. See
“Engine Coolant Temperature Gage” and “Engine
Coolant Temperature Warning Light” in the Index.
You also have a LOW COOLANT warning light on
your instrument panel. See “Low Coolant Light” in
the Index.
If Steam Is Coming From 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.
