light BUICK PARK AVENUE 1997 Service Manual

Malfunction Indicator Lamp
(Service Engine Soon Light)
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.
1 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 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.
0 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
The following may prevent more serious damage to
your vehicle:
e Reducing vehicle speed.
e Avoiding hard accelerations.
0 Avoiding steep uphill grades.
0 If you are 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. Find a safe place to park your vehicle.
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.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following: 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.
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 one or more of these conditions,
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.

Oil Pressure Light
OIL
This light tells you if there
could be a problem with
your engine oil pressure.
There are three ways the oil pressure light can come on
briefly, which are normal and don’t show a problem.
They are:
The light comes on when you turn your key to RUN.
It goes off once you turn the key 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.
If you’re “idling” at a stop sign, the light may blink
on and then off.
If you make a hard stop, the light may come on
for a moment.
When this light comes on and stays on, and a chime
sounds, it means oil isn’t
going through your engine
properly. You could
be low on oil, or you might have
some other oil problem. See your dealer for service.
Don’t keep driving if the oil pressure is
low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

Service Vehicle Soon Light
SERVICE
VEHICLE SOON
This light will come on if
you have certain
non-emission related
vehicle problems.
I
These problems may not be obvious and may affect
vehicle performance or durability. Consult a qualified
Buick dealership for necessary repairs to maintain top
vehicle performance. The light will come on briefly
when your ignition is turned on to show that it is
working properly.
Fuel Gage
UNLEADED FUEL ONLY
Your fuel gage shows
about how much fuel is in
your tank.
It works only when the ignition is on. When the
indicator moves to the edge of the low fuel warning
band, the low fuel light will turn on and a chime will
sound. You still have a little fuel left, but you need to get
more fuel right away.
A concern owners have had about the fuel gage is that it
takes more (or less) gas to fill up than the gage indicated.
For example, the gage may have indicated
half full, but it took more
(or less) than half of the tank's
capacity to fill it. This situation is normal and indicates
nothing wrong with the fuel gage.

Head-Up Display (HUD)
(If Equipped)
If the HUD image is too bright, or too high in
your field
of view, it may take you more time to
see things you need to see when it's dark outside,
Be sure to keep the
HUD image dim and placed
low in your field
of view.
If your vehicle is equipped with the HUD, you can see
some of the driver information that appears on your
instrument cluster as a reflection in the windshield.
The information may be displayed
in English or metric
units and consists of the following:
Speedometer Reading
Turn Signal Indicators
High Beam Headlamp Indicator
Check Gages Message The
HUD shows these images
when they are lighted on
the instrument panel cluster.
Be sure to continue scanning your displays, controls and
driving environment just as you would in a vehicle
without
HUD. If you never look at your instrument
panel, you may not see something important, such as a
warning light.

Comfort Controls
This section tells you how to operate your comfort
controls. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
With these systems, you can control the heating, cooling
and ventilation in your Buick. Your vehicle also has a
flow-through ventilation system described later in
this section.
Personal Choice Comfort Controls
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings for temperature, air delivery mode, fan and passenger climate control
(ordoff) status. The Personal Choice settings recalled
are determined by the transmitter used to enter the
vehicle. After the
UNLOCK button of a remote keyless
entry transmitter is pressed, and the ignition is in
RUN,
the climate control will adjust to the last settings of the
identified driver. The settings can also be changed by
briefly pressing one of the
MEMORY seat switches
located on the driver’s door panel. When adjustments
are made, the new settings
are automatically saved for
the driver.
Dual Automatic ComforTemp Climate Control
Your Buick has the dual automatic comfortemp climate
control system. The following information tells you how
it works.
You will hear a beep each time a button is pushed and a
small light on the button will indicate which buttons are
active. The lights are on all buttons except
TEMP, FAN
and
AIR FLOW. The display will show fan speed,
comfort level setting and airflow direction for a few seconds whenever any button, except for the rear
defog, is pushed, and then it will display the outside
temperature. The outside temperature reading is most
accurate when the vehicle is moving.
During stops, when driving slow, or when the engine is
first started after a short trip, the outside temperature
reading can be affected by road or engine heat. In order
to ensure proper automatic climate control operation, the outside temperature display may not update as quickly
as expected.
