Headlight “On” Warning
If you open the door while leaving the lights on, you will
hear a warning chime.
Daytime Running Lights (Canada Only)
The Canadian Federal Government has decided that “Daytime Running Lights” (DRL)
are a useful feature, in
that DIU can make your vehicle more visible to
pedestrians and other drivers during daylight hours. DRL
are required on new vehicles sold in Canada.
Your DRL work with a light sensor on top
of the
instrument panel. Don’t cover it up. The low beam
headlights will come on at reduced brightness
in daylight
when:
The ignition is on
The headlight switch is off, and
The parking brake is released.
At dusk, the exterior. lights will come bn &.nomatically
and the low
beams will change to full brightness. At
dawn, the exterior lights will go out and the low beams
will change to
the reduced brightness of DRL (if the
headlight switch is off).
Of course, you may still turn on the headlights any time
you need to.
To idle your vehicle with DRL off, set the parking brake
while the ignition is in the
“Off’ or “Lock” position.
Then start the vehicle. The
DRL will stay off until you
release the parking brake.

Speedometer and Odometer
Your speedometer lets you see your speed in both miles per
hour (mph) and kilometers per hour (ludh). Your odometer
shows how
fkr your vehicle has been driven, in either
miles (used
in the U.S.) or kilometers (used in Canada).
Your Buick has a “tamper-resistant odometer? If you can
see silver lines between the numbers, probably someone
has
tried to turn it back. The numbers may not be true.
You
may wonder what happens if a vehicle has to have a
new odometer installed. If possible, the new one has to
be set to the same reading the old one had. If it can’t \
be,
then it’s set at zero, but a label on the driver’s door\
must show the old reading and when the new one was installed.
Trip Odometer
The trip odometer can tell
you how
far your vehicle
has been driven since you last set the trip odometer to
zero.
To set the trip odometer to
zero, press the reset knob to
the right of the trip
odometer.
Warning Lights, Gages and
Indicators
This section describes the warning lights and gages that may
be on your vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to your
warning lights and gages could
also save you or others
from injury.
Warning lights go on when there may be or is a problem
with one
of your vehicle’s functions. As you will see in
the details on the next few pages, some warning lights
come on briefly when you
turn the ignition key just to let
you know they’re working. If you are familiar with this
section, you should not be alarmed when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow the manual’s advice.
Waiting to do repairs can be costly-and even dangerous.
So please get to know your warning lights and gages.
They’re a big help.

Fuel Gage
Your fuel gage tells you about how much fuel you have
left, when the ignition is on. When the indicator nears
“E” (Empty), 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
“F” (Full).
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, speed
up or brake.
The gage doesn’t go back to “E” when you turn off the
ignition.
Engine Oil Pressure Light
If you have a problem with
your
oil, this light may stay
on after you start your
engine, or come on when
you are driving.
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 it fixed right
away.
The
oil light could also come on in three other situations:
When the ignition is on but the engine is not funning,
the light will come on as a test to show you it is
working, but the light will go out when
you turn the
ignition to “Start? If it doesn’t come on with the
107

ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.
Sometimes when the engine is idling at a stop, the light
may blink on and
off. This is normal.
If you make a hard stop, the light may come on for a
moment.
This is normal.
1 A CAUTIONS
Don't keep driving if the oil pmssure is low. If
you do, your engine can become QO hot that It
catches flm. "ybu or others could be burned.

I
Battery Light
The battery warning light
will come on briefly when
you
turn on the ignition,
but the engine is not
running, as a check to
show
you it is wcrking. Then it
should go out. If it stays on,
or comes on while you are
driving, you may have a
problem with the electrical
charging system. It could
indicate that you have a
or another electrical
. ., . loose generator drive belt
problem. Have it checked right away. Driving while this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to
turn off all your accessories, such as the radio
and air conditioner.

Volts Gage (Option)
When your engine is not
running, but
the ignition is
on (in the “Run” position),
the gage shows your
battery’s state of charge
in
DC volts. When the engine
is running, the gage shows
the condition of the
charging system. Readings
between the red warning
zones indicate the normal
operating range.
Readings in either red
warning zone indicate a possible problem in the electrical
system. Have your vehicle serviced immediately.
Brake System Warning Light
Your Buick‘s hydraulic
brake system is divided into
two parts. If one part isn’t working, the other part can still work and stop you. For
good braking, though, you
need both parts working
well.
If the warning light
goes on, there could be a
brake problem. Have your
brake system inspected right away.
This light should come on
as you start the vehicle. If it doesn’t come on then, have it
fixed
so it will be ready to warn you if there’s a problem.
This light will also come on when you set your parking
brake, and will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes 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 Buick” in the Index.)

The air conditioner compressor operates in all AIR COND
positions, and in DEF (Defrost) when the outside
temperature is above about 40°F (4.5"
C).
Ventilation
For mild outside temperatures, when little heating or
cooling is needed, slide the upper lever to
VENT. Air
flow is through the instrument panel outlets. Rotate the
control next to the outlets to turn on, adjust or
turn off
the air flow. Adjust the lower lever on the control panel
to the temperature desired.
Heating
When outside temperatures are cold, sliding the upper
lever to
HEATER and the lower lever to HOT will send
heated air through the heater ducts, and some through the
defroster vents.
VENT and HEAmR are labeled
ECONOMY positions because the air conditioner
compressor doesn't run
in these two settings. This
reduces engine load, resulting
in improved he1 economy.
If either setting fails to keep you comfortable, or causes
your windows
to fog up, slide the upper lever to one of
the
AIR COND positions, or to DEF (Defrost).
Defrosting
The DEF setting directs most of the air through the
defroster vents, and some through the heater ducts.
Defogging Windows with Four Season
Climate Control
To quickly defog the windshield, set the upper lever to
DEF and move the hn switch to HI. Slide the lower
lever
to HOT.
In damp, cool weather (temperatures about 45"-65"F,
7"- 18" C), you can use BI-LEV to defog the side windows.
Set the upper lever to
BI-LEV and the fan switch to HI.
Aim the side vents toward the side windows. For increased
air flow to the side vents, close the center vents.
Rear Window Defogger (Option)
--
The rear window defogger
uses
a warming grid to
remove fog from the rear
window.
In winter, it can
also keep ice from forming
on the rear window.
Press the
ON portion of the
switch. The indicator light
will glow. The rear window
defogger will
turn off
automatically after about
10
minutes of use. You can
also turn
it off by turning
off the ignition or pressing the
OFF portion of the
switch.
