PASS-Key@ I1
Your vehicle is equipped
with the PASS-Key
I1
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key I1 is a passive
theft-deterrent system. It
works when you insert or
remove the
key from
the ignition.
PASS-Key
I1 uses a resistor pellet in the ignition key
that matches a decoder
in your vehicle.
When the PASS-Key I1 system senses that someone
is
using the wrong key, it shuts down the vehicle’s starter and
fuel systems. For about three minutes, the starter won’t
work and fuel won’t
go to the engine. If someone tries to
start your vehicle again or uses another key during this
time, the vehicle will not start. This discourages someone
from randomly trying different keys with different resistor
pellets in
an attempt to make a match.
The ignition key must be clean and dry before it’s inserted
in the ignition or the engine may not start. If the engine
does not start and the SECURITY light is flashing, the key
may be dirty or wet. Turn the ignition off. Clean and
dry
the key. Wait about three minutes and try
again.
If the starter still won’t work, and the key appears
to be clean and dry, wait about three minutes and 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 starter won’t work with the other key, your
vehicle needs service. If your vehicle does start, the first
ignition key may be faulty. See your dealer or a
locksmith who can service the PASS-Key
11.
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won’t work. The
SECURITY light will then come
on. But you don’t have
to wait three minutes before trying another ignition key.
See your dealer or a locksmith who can service the
PASS-Key
I1 to have a new key made.
If you’re ever driving and the SECURITY light comes
on, you will be able to restart your engine if
you turn it
off. Your PASS-Key I1 system, however, is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by the PASS-Key I1 system.
If you lose or damage a PASS-Key
I1 ignition key, see
your dealer or
a locksmith who can service PASS-Key I1
to have a new key made. In an emergency, call the Buick
Premium Roadside Assistance Center at
1-800-252-
1 112. In Canada, call 1-800-268-6800.

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 the air bag symbol. 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 modules, the wiring
and the crash sensing and diagnostic module. For more
information on the air bag system, see “Air Bag” in
the Index.
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 a problem.
Charging System Light
4
+I
The charging system light
will come on briefly when
you turn on the ignition, as
a check to show you it’s
working. Then it should
go out.
If it stays
on, or comes on while you are driving, you
may have a problem with the charging system. It could
indicate that you have a loose drive belt or another
electrical 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.

Low Coolant Warning Light
LOW COOLANT
If this light comes on, your
system is low on coolant
and the engine may
overheat. See “Engine
Coolant”
in the Index and
have your vehicle serviced
as soon as you can.
The light will come on briefly when your ignition is
turned
on to show you that it is working properly.
Low Tire Light (If Equipped)
LOW
TIRE
The tire pressure monitor
system can alert you to
a
large change in the pressure
in one tire. After the system has “learned”
tire pressures with
properly inflated tires, the
LOW TIRE light will come
on if the pressure in one tire becomes
12 psi (83 kPa)
lower than the other three tires. The tire pressure
monitor system won’t alert you if the pressure in more
than one tire
is low, if the system is not yet calibrated, or
if the vehicle is moving faster than
70 mph (1 10 kdh).
When the
LOW TIRE light comes on, you should stop
as soon as you can and check all your tires for damage.
(If a tire is flat, see “If a Tire Goes Flat” in the Index.)
Also check the tire pressure in all four tires as soon
as
you can. See “Inflation - Tire Pressure” in the Index.
The light will stay on until you turn off the ignition or
reset the system. See “Tire Pressure Monitor System” in
the Index.
The
LOW TIRE light also comes on briefly when you
turn the ignition key to RUN. If the light doesn’t come
on then, have it fixed
so it will be there to tell you if the
pressure in a tire is low or high.

Malfunction Indicator Lamp (Service Engine Soon Light)
Your vehicle is equipped
with a computer which
SERVICE ENGINE fuel, ignition and emission
monitors
operation of the
SOON 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. 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.
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. Dealer or qualified service center diagnosis
and service may be required.
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.

Have you recently cnanged 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.
Qil Warning 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 the following
situations:
0
0 The light will come on briefly when you turn on the
ignition to show you that it is working properly.
(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.)
Sometimes when the engine is idling at a stop, the
light may blink on and off. This
is normal.

Low Oil Level Light
Don’t keep driving if the oil pressL-d 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.
LOW
OIL
Your engine is equipped
with an oil level monitoring
system. When the ignition
key
is turned on, the
LOW
OIL light will come
on briefly.
If the light does not come on briefly, have it fixed
so it
will be ready to warn you if there’s a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine
off. Check the oil level using the
engine oil dipstick. (See “Engine Oil” in the Index.) If
the light does not flash, have the
low oil level sensor
system repaired
so it will be ready to warn you if there’s
a problem.
The oil
level monitoring system only checks oil level
during the brief period between key on and engine
crank. It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned off for a
considerable period of time, allowing the oil normally in
circulation
to drain back into the oil pan.

Change Oil Soon Light
Your CHANGE OIL SOON
light should come on as a
CHANGE OIL
SOON
bulb check when you start
the engine.
Security Light
SECURITY
This light will come on
when you turn the key
to
START and stay on until the
vehicle starts.
If this light stays on for about
20 seconds after you turn
on the ignition, have the oil changed.
When to change your oil also depends on driving habits
and conditions because
they directly affect engine speed,
coolant temperature and vehicle speed. Because of this,
the CHANGE OIL
SOON light may come on as early as
2,000 miles (3,200 km) or less for harsh conditions.
Also see “Maintenance Schedule” in the Index for
further instructions on when
to change your oil.
To reset the CHANGE OIL SOON light, see “CHANGE
OIL SOON Light, How to Reset” in the Index. Also, see
“Oil Life Monitor”
in the Index. It
will also flash if your ignition key is too dirty or wet
for the PASS-Key I1 system to read the resistor pellet.
See “Pass-Key
11” in the Index.
If the resistor pellet is damaged or missing, the light will
come
on.
If you’re ever driving and the SECURITY light comes
on, you will be able to restart your engine
if you turn it
off. Your PASS-Key I1 system, however, is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by the PASS-Key I1 system.

Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster
if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist. But
you will use
it when you brake. Once the power assist is
used up,
it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test
is going on, and you may even notice that your
brake pedal moves or pulses a little. This is normal.
ANTI -
LOCK
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash. See “Anti-Lock
Brake System Warning
Light”
in the Index.

Before closing the hood, be sure all the filler caps
are on properly. Then just pull the hood down and close
it firmly.
3800 Supercharged (Code 1) Engine
(If Equipped)
Your vehicle may have a 3800 Supercharged engine.
The supercharger is a device which is designed to pump
more air into the engine than it would normally use.
This
air is mixed with fuel, which creates increased
engine power. Since the supercharger is a pump and is
driven from an engine accessory drive belt, increased
pressure
is available at all driving conditions.
The Powertrain Control Module (PCM), works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such as during
idling and light throttle cruising, the excess air that the
supercharger is pumping is routed through a bypass. All
of these controls working together provide high
performance character and fuel efficiency in the
3800
Supercharged L67 engine.
Engine Oil
LOW
OIL
If the LOW OIL light on the
instrument panel comes on,
it means you need to check
your engine oil level right
away. For more
information,
see “Low Oil
Level Light” in the Index.
You should check your engine oil level regularly; this
is
an added reminder.
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
