NOTICE:
Your engine is designed to work with the
electronics in your vehicle.
If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer.
If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of
this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle’’ in the Index.
Engine Coolant Heater (Option)
In very cold weather, 0” F (-‘18 O C) or colder, the engine
coolant heater can help. You’ll get easier starting and
I
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.

THIRD (3) or DRIVE (D): If your automatic transaxle
does not have AUTOMATIC OVERDRIVE
(@),
DRIVE (D) is for normal driving, at all speeds, in most
street and highway situations.
If your automatic transaxle has overdrive, THIRD
(3) is
also used for normal driving, however, it offers more
power and lower fuel economy than AUTOMATIC
OVERDRIVE
(a).
Here are some times you might choose THRD (3) or
DRIVE
(D) instead of AUTOMATIC OVERDRIVE (a):
- When driving on hilly, winding roads.
- When towing a trailer, so there is less shifting
between gears.
- When going down a steep hill.
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.
2-18
ProCarManuals.com

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 selector lever is put in FIRST (I), 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 to hold your vehicle in
position on a hill.
Parking Brake
To set the parking brake,
hold the regular brake pedal
down with your right foot
and push down the parking
brake pedal with your left
.foot. If the ignition is on,
the.brake system warning
light will come on.
To release the parking
brake, hold the regular
brake pedal down. Pull the
brake release lever.

Engine Coolant Temperature Gage
II k
TEMPERATURE -Z
Domestic Canadian
This
gage 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, and stop your
engine as soon as possible.
The section “Problems on the Road,” in this manual
explains what to do. See “Engine Overheating” in
the Index.
Malfunction.Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE
SOON
Domestic Canadian
Your
Buick is equipped with a computer which
monitors operation
of the fuel, ignition and emission
control systems.
2-54
ProCarManuals.com

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 to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem
is apparent, which may prevent more
serious damage
to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0
0 Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your vehicle. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and service may be required.

If the Light Is Flashing If the Light Is On Steady
The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as soon
as it is possible.
If the light stops flashing and remains on steady, see
“If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key off, wait at least
10 seconds and restart the engine.
If the light remains on steady, see “If the Light
Is On
Steady” following. If the light
is still flashing follow the
previous steps, and drive the vehicle
to your dealer or
qualified service center for service. You
may be able to correct the emission system
malfunction by considering the following:
Did you just put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left off or improperly installed. This will
allow fuel to evaporate into the atmosphere. A few
driving trips should turn the light off.
Did you just drive through a deep puddle
of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light
off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently
as designed since small amounts of
air are sucked into the
fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel
cap properly. It
will take a few driving trips to turn the light off.
ProCarManuals.com

Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause
the light
to turn on.
If
you experience this condition, change the fuel brand
you
use. It will require at least one full tank of the
proper fuel
to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper
test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that may have developed.
Engine Oil Pressure Light
If you have a problem with
your oil, this oil pressure
warning light may stay
on
after you start your engine,
or come
on when you are
driving. Stop your vehicle
and shut
off the engine if
this light stays on.
This indicates that oil is
not going through your
engine quickly enough
to keep it lubricated.
The engine could be low on oil, or could have
some other oil problem. Have your vehicle
serviced immediately.

Fuel Gage

BUNLEADED FUEL ONLY
II
Domestic Canadian
Your fuel gage tells you about how much fuel you have
left, when the ignition is on. When the indicator nears
EMPTY (E), you still have a little fuel left, but you
should get more soon. Here are four
things that some owners ask about. None
of these show a problem with your fuel gage and
are
normal operating characteristics:
At the service station, the gas pump shuts off before
the gage reads FULL (F).
It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took
a
little more or less than half the tank's capacity to fill
the tank.
The gage moves a little when you turn a corner,
0 The gage doesn't go back to EMPTY (E) when you
speed
up or brake.
