To Use the Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord
is attached to the diagonal brace near the
coolant recovery tank.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
I
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.
I
4. Before starting the engine, be sure to unplug and
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.

Move the lever up as far as it will go.
3. Move the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is
in PARK (P).
Leaving Your Vehicle With the
~ r-gine Rul:--'--T
I I
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 enginc
running, be sure your vehicle is in
PARK (P) anu 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).

Engine Coolant Temperature Light Engine Coolant Temperature Gage
h -
TEMP
This light
tells you that your
engine coolant has
overheated or your radiator
cooling fan is not working.
The light should come on
briefly when your ignition
is turned on to show you
that it is working.
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!
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. 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. The
light will come on briefly
when your ignition is turned
on to show
you that it is
working properly.
Low Traction Light
LOW TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on.
(Also see “Anti-Lock Brake
System Active Light”
earlier
in this section.)
Slippery road conditions may exist if the low traction
light comes on,
so adjust your driving accordingly. The
light will stay on for a few seconds after the anti-lock
system stops adjusting brake pressure.
The
LOW TRAC 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 anti-lock brake system is active.

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 green 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 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.
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.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK (P) yet.
Have someone place chocks under the
trailer’s wheels.
When the wheel chocks are
in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and shift
to PARK (P).
Release the regular brakes.
