parking brake set, a chime will also come on until you
release the parking brake. If the light and chime stay on
after your parking brake is
fully released, it means you
have a brake problem. If the light and chime come on
while driving, pull
off the road and stop carefully. You
may notice that the pedal is harder to push. Or, the pedal
may go closer to the floor. It may take longer to stop. If
the light is still on, have the vehicle towed for service.
(See “Towing Your Car” in the Index.)
1 &!A CAUTION:
Your brake system may not be working properly
if the brake warning light is on. Rriving with the
brake warning light on can lead to an accident. If
the light is still on after you’ve pulled off the road
and stopped carefully, have the vehicle towed for
service.
Anti-Lock Brake System Warning Light
1-
ANTI
LOCK
With anti-lock, this light will go on when you start your
engine and may stay on for several seconds or
so. That’s
normal. If the light doesn’t come on, have it fixed
so it
will be ready to warn you if there is a problem.
If the light stays on or comes
on when you’re driving,
stop as soon as possible and turn the key off. Then start
the engine
to reset the system. If the light still stays on,
or comes
on again while you’re driving, your Buick
needs service. Unless
the regular brake system warning
light is also
on, you will still have brakes, but not
anti-lock brakes. If the regular brake system warning
light
is also on, see “Brake System Warning Light”
earlier
in this part.

/I CAUTION:
If you let your tires spin at high speed when the
“TRACTION OFF“ warning light is on, they can
explode and you or others could be injured. And,
spinning your tires with the “TRACTION OFF”
warning light on can cause the transaxle to
overheat
or can cause other problems. That
could
cause an engine fire or other damage.
When you’re stuck,
spin the wheels as little as
possible. Don’t spin the wheels above 35 mph
(55 km/hl as shown on the speedometer.

TEMP
This light tells you that your engine coolant has
overheated or your radiator cooling fans are
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.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating”
in the Index.

Engine Coolant Temperature Gage
If you have the Gage Cluster, 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.

when the ignition is on, but the engine is not running, as
a check to show
you it is working. If it does not come on
at all, have
it fixed right away. If it stays on, or it comes

Engine Oil Pressure Light And Gage
i
This light tells you if there could be a problem with your
engine oil pressure.
If your car has the optional gage cluster, you can read
your oil pressure directly from the gage on your
instrument panel.
There are three ways this light can come
on briefly,
which is normal and doesn’t show a problem. They are:
1. The light comes on when you turn your key to
“Run.”
It goes off once you turn it to Start. That’s
just a check to be sure
the light works. If it doesn’t,
be sure to have
it fixed so it will be there to warn you
if something goes wrong.

2. If you’re “idling” at a stop sign, the light may blink
3. If you make a hard stop, the light may come on for a

But, when this light comes
on and stays on, it means
oil isn’t going through your engine properly.
You could
be low on oil, or you might have some other oil
problem.

A CAUTION:
Don’t keep driving if the 001 pressure is low. If
you do, your engine can become so hot that it

‘‘Check Oil Level” Light (Option)
CHECK
OIL LEVEL.,
The “Check Oil Level”
light is lit for three seconds
as a bulb check each time
the ignition key is turned to
the RUN position.
If
the light doesn’t come on, have your vehicle serviced.
If the engine
oil is more than one quart low, the light
will come
on briefly, then go off for 15 - 25 seconds,
and then come back
on for 20 - 40 seconds.
However,
if it has not been more than eight minutes
since the engine was
shut off, the system will not
register a low engine oil condition.
If the “Check Oil Level” light comes back on, the
engine oil should be checked at the dipstick and then
brought up
to the proper level if necessary. See
“Engine Oil”
in the Index.

“Change Oil Soon’’ Light (Option)
This light is activated by
the Engine Oil Life
Monitor System. It
indicates that the engine oil
has degraded enough to
require changing. See
“Engine Oil”
in the Index.
After changing the engine oil, the system should be
reset.
This will cause the “Change Oil Soon” light once
again, to be lit for just
the bulb check period of 3
seconds.
This
is determined by electronically monitoring engine
speed, coolant temperature and vehicle speed. Since the
change interval is dependent on driving habits and
conditions, the “Change Oil Soon” light may come on as
early as
2,000 miles or less for harsh circumstances.
The “Change Oil Soon” light is lit for three seconds as a
bulb check each time the ignition key is turned to
the
RUN position. If an oil change is required, it will stay
on for 60 seconds each time the engine is started. If the
“Change Oil Soon” light is on continuously, there is a
problem with the Oil Life Monitor System and service
is
required. The reset button
is inside this hole, which is under the
passenger’s side of the instrument panel, near the door.
With the ignition key in
the RUN position, but the
engine not started, use a pen
to push the reset button,
holding
it in for at least 5 seconds but not more than 60
seconds. After 5 seconds, the “Change Oil Soon” light
will flash
4 times and then turn off. This indicates that
the Oil Life Monitor System has been reset.

Auto
When the system is set for
automatic, air will come
from the floor outlets, the
instrument panel outlets, or
both.
Fan speed will vary
(unless a blower

the system gets to and

setting
you have selected.
Dual Zone
____
The front seat passenger
can control air temperature
in their seating area.
The display will show the set temperature and blower
speed.
In cold weather the system will delay turning on the fan,
to avoid blowing cold air. The length
of the delay
depends
on engine coolant temperature, outside
temperature, and time since the engine was last started.
Pushing a
LO or HI blower button will override this
delay, and cause the fan to start.
To rid the system of stale air in warm weather, air will
come out
of the floor outlets for a short time. The air temperature for
the right side of the front seat
can be set using the control on
the passenger’s door.
Both
DUAL ZONE and AUTO buttons will light up. To
turn off this part of the system , push the DUAL ZONE
button again.

Bi-Level
This setting is designed for use on sunny days when the
air is only moderately warm or
cool. On days like these,
the sun may adequately warm your upper body, but your
lower body may
not be warm enough.
The Bi-level setting directs outside air into your vehicle
in two ways. Cool air is directed toward your upper
body through the instrument panel outlets, while slightly
warmed air is directed through the heater outlet at your
feet.
The air conditioner compressor operates in all Air
Conditioning positions and the Defrost position when
the outside temperature is above
48 OF (9OC).
When you don’t need to cool the outside air, use the
VENT, HEAT, or DEFROST settings. Adjust the
temperature control for comfort. You’ll get better fuel
economy (gas mileage) if you’re
not cooling the outside
air. When
you cool the air, your engine runs a
refrigeration compressor, and it has to work harder.
Vent
For mild outside temperature, when little heating or
cooling is needed, use the
VENT setting. Air will flow
through the instrument panel outlets. Use
the air outlets to
turn on, adjust and turn
off the air flow. Adjust the
temperature lever to the desired temperature.
Heater
When outside temperatures are cold, pressing the HTR
setting and adjusting the temperature lever
will send
warm air through the floor outlets, and some through the
defroster vents.
Def
The Defrost setting directs most of the air flow toward
the windshield. Use defrost when
you want to remove
fog or ice from
the windshield. When it’s 48 OF (9 “C) or
warmer, you’ll get cooled air.
Defog
Air entering the car will be evenly split between the
floor outlets and the outlets near the windshield. You
can control the temperature of the air and the fan speed
to clear the foggy windows.
126

Rear Window Defogger (Option)
The lines you see on the
rear window warm the
glass. Press the button to
start warming your
1 window. After-10 minutes it
will go off by itself, or
pressing the button again
during the heating cycle will shut it off. If you need
additional warming time,
push the button again.
Scraping the inside of your rear window could
cut and damage the heater. Your warranty would
not cover this damage. Don’t put decals there
you might have to scrape them
off.
Audio Systems
Your Delco@ audio system has been designed to operate
easily and give years
of listening pleasure. But you will
get the most enjoyment out your system if you acquaint
yourself with it first. Find
out what your Delco @ system
can do and how
to operate all its controls, to be sure
you’re getting the most out of the advanced engineering
that went into
it.
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (16 to 65 km). And,
tall buildings or hills can interfere with
FM signals,
causing the sound to come and go.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble
to reduce this noise.
