When the PASS-Key
III system senses that someone is
using the wrong key, it shuts down the vehicle’s starter
and fuel systems. The starter will not work and fuel
will stop being delivered to the engine. Anyone using
a trial-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes. If
when trying to start the vehicle, the engine does not
start and the
SECURITY light comes on, the key may
have a damaged transponder. Turn the ignition off
and
try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse (see “Fuses and
Circuit Breakers” in the Index). If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does start, the first key may be faulty.
See your Buick dealer or a locksmith who can service
the PASS-Key I11 to have a new key made.
It is possible for the PASS-Key
111 decoder to learn the
transponder value of
a new or replacement key. Up to
ten additional keys may be programmed for the vehicle.
This procedure is for learning additional keys only. If all
the currently programmed keys are lost or do not
operate, you must see your Buick dealer or a locksmith
who can service PASS-Key
I11 to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
I11 to get a new key blank that is a cut
exactly as a current black colored driver’s key that
operates the system.
Do not use a gray colored valet
key for this procedure.

NOTICE:
I
Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
damage your starter motor.
2. If it doesn’t start right away, hold your key in
START for about three to five seconds at a time until
your engine starts. Wait about
15 seconds between
each try to help avoid draining your battery.
3. If your engine still won’t start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again, do the same thing, but
this time keep the pedal down for five or six seconds.
This clears
the extra gasoline from the engine.
After waiting about
15 seconds, repeat the normal
starting procedure.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle.
If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer.
If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to
do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.
Engine Coolant Heater (Option)
In very cold weather, 0°F (- 1 8 O C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum
of
four hours prior to starting your vehicle.

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 may also have 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.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows
AIR BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag” in the Index.
AIR
BAG
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should
go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away. The
air bag readiness light should flash for a few
seconds when you turn the ignition key to
RUN. If the
light doesn’t
come on then, have it fixed so it will be
ready to
warn you if there is problem.
Battery Warning Light
VOLT
When you turn the key to
RUN, this light will come
on briefly, to show the
battery charging system
is working.
When the light goes off and stays off, the charging
system is working.
If the light stays on, a chime will sound indicating you
need service, and you should take your Buick
to the
dealer at once. To save your battery until you
get there,
turn off all accessories and turn
off your climate
control system.

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.
ProCarManuals.com

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.
