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 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. 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
wing 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.
AI natic Transaxle Operation . ~
Your automatic transaxle
will have a shift lever on the
2-22
ProCarManuals.com

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 kmk), 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 (l), 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 out of PARK (P)
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) 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 parking pawl in the transaxle, so you
can pull the shift lever out of PARK (P).

Traction Control System Warning Light
(If Equipped: 3800 Supercharged
Engine Only)
TRAC
OFF
The traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the traction
control button, the warning light will come on and
stay on.
To turn the system back on, press the button
again. The warning light should go off. (See
“Traction Control System” in the Index for
more information.)
If there’s a brake system problem that is specifically
related to traction control, the traction control system
will turn
off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.

Engine Coolant Temperature Light
h -
TEMP
This light tells you that
your engine coolant has
overheated or your radiator
cooling fan is not working.
The light will come
on
briefly when your ignition
is turned on to show you
that it is working.
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
.. 1. TEMP
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
I OW 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.
Malfunction Indicator Lamp (Service Engine Soon Eight)
SERVICE ENGINE
SOON
Your Buick is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called OBD
I1 (On-Board
Diagnostics-Second Generation) and
is intended
to assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. (In Canada,
OBD I1 is replaced by
Enhanced Diagnostics.) The
SERVICE ENGINE
SOON light comes on and a chime will sound to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician
in correctly
diagnosing any malfunction.

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 kmh) 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. Apply your regular brakes, but don’t shift into
PARK (P)
yet.
2. Have someone place chocks under the
trailer’s wheels.
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 shift to PARK
(P).
5. Release the regular brakes.
