Malfunction Indicator Lamp (Service Engine Soon Light)
I
SERVICE
ENGINE SOON
Your Oldsmobile 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 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:
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Retailer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Retailer or qualified service center diagnosis and
service may be required.

hauled as soon as it is possible.
If the lightstops 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
1 previous steps, and drive the vehicle to your retailer 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 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 .evap.orate 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.

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 retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Oil Warning Light c
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.

When the ignition is on but the engine is not running,
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
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.
If you make a hard
stop, the light may come on for a
moment. This is normal.
A The oil light could also come on in two other situations:

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.

Damage to your engine from neglected oil
problems can be costly and is not covered by

Air Conditioning
On very hot days, open the windows long enough to’let
hot, inside air escape. This reduces the time the
compressor has to run, which should help fuel economy.
For quick cool-down on very hot days, use
MAX with
the temperature knob all
the way in the blue area. If this
setting is used for long periods of time, the air in your
vehicle may become too
dry.
For normal cooling on hot days, use VENT with the
temperature knob in the blue area and the A/C button
pushed in. The system will bring in outside air and
cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI-LEVEL with the temperature knob set
for comfort and the A/C button pushed in. The system
will bring in outside air and direct it to your upper body,
while sending slightly warmed air
to your lower body.
You may notice this temperature difference more at
some times than others.
Heating
On cold days, use FLOOR with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it’s
cold outside (0°F (-18°C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in the Index.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Your vehicle also has the
flow-through ventilation system described later in
this section.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the
red area. To warm passengers while keeping the
windows clean, use DEFOG.

Manual Control
If you prefer to manually control the heating, cooling and ventilation in your vehicle, set the system to the
temperature and fan speed you want. Next, push the
desired airflow direction pushbutton. The system will
try to maintain the temperature you set using the mode
you select. The following suggestions will help the
system run more efficiently in manual mode.

Understanding Radio Reception
F" Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (1 6 to 65 km). 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 if you ever get it.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe sound level before your hearing adapts to it.
To help avoid hearing loss or damage:
0 Adjust the volume control to the lowest setting.
0 Increase volume slowly until you hear comfortably
and clearly.
I NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can add
what you want.
If you can, it's very important to
do it properly. Added sound equipment may
interfere with the operation
of your vehicle's
engine, Delco radio or other systems, and even
damage them. Your vehicle's systems may interfere
with the operation
of sound equipment that has
been added improperly.
So, before adding sound equipment, check with
your retailer and be sure to check Federal rules
covering mobile radio and telephone units.
