Passlock TM
Your vehicle is equipped with the Passlock
theft-deterrent system.
Passlock
is a passive theft-deterrent system. The system
is armed once the
key is removed from the ignition.
Passlock enables fuel if the ignition lock cylinder
is
turned with a valid key. If a correct key is not used, fuel
is disabled.
During normal operation, the SECURITY light will go
off after the engine is started.
If the engine stalls and the SECURITY light flashes,
wait about
10 minutes until the light stops flashing
before trying to restart the engine. Remember to release
the key from the START position
as soon as the
engine starts.
If the engine does not start after three (3) tries, the
vehicle needs service.
If you are driving and the SECURITY light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock system is not
working properly and must be serviced by your retailer.
Your vehicle is not protected by Passlock at this time.
You may
also want to check the fuse (see “Fuses
and Circuit Breakers” in the Index). See your retailer
for service.
If the SECURITY light comes on while the engine is
running, a problem has been detected and the system
may need service. See your retailer for service.
In an emergency, call the Oldsmobile Roadside
Assistance Center at
1 -800-442-OLDS (6537).

Warning Lights, Gages
and Indicators
This part 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 come
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 start the
engine 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
this 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.
Your vehicle also has
a driver information system that
works along with the warning lights and gages. See
“Driver Information System”
in the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about
20 seconds, then it
will flash for about 55
seconds. If the driver’s belt
is already buckled, neither
the chime nor the light will
come on.

Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
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 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. 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. This may
prevent more serious damage to your vehicle. This
system
is also designed to assist your service technician
in correctly diagnosing any malfunction. 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.

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. Retailer or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.

If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 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 clo so,
stop the vel?icle. 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
retailer or qualified service center for service.
If the Light Is On Steady
YOLI may be able to correct the emission system
malfunction by considering
the following:
Did you recently
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.
A loose or
missing fuel cap
will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed 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.
Have you recently changed brands
of fuel?
If so, be s~~re to file1 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 YOLI experience one or more of these conditions,
change the fuel brand
yo^^ 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.

Engine Oil Pressure Gage
The oil pressure gage shows
the engine
oil pressure in
psi (pounds per square inch)
when the engine
is running.
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problems causing low
oil pressure.
I
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.

Understanding Radio Reception
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.
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). Tcd1
buildings or hills can interfere with FM signals, causing
the sound to come and go.
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:
Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
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 Electronics 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 amd telephone units.
