2000 BUICK REGAL ignition

2-64 Traction Control System Active Light
When your traction control
system is limiting wheel
spin, this light will come on.
Slippery road conditions may exist if the traction
control system active light comes on, so adjust your
driving accordingly.
The light will stay on for a few seconds after the traction
control system stops limiting wheel spin.
Low Traction Light
This light will also come on
when the Traction Control
System is limiting wheel
spin. You may feel or hear
the system working, but this
is normal.
Slippery road conditions may exist if the low traction
light comes on, so adjust your driving accordingly.
The light will stay on for a few seconds after the traction
control system stops limiting wheel spin. See ªTraction
Control Systemº in the Index.
The low traction 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 when
the Traction Control System is active.

2-65 Engine Coolant Temperature Light
This light tells you that
your engine coolant has
overheated or your radiator
cooling fan is not working.
The light will come on briefly when your ignition is
turned on to show you that it is working.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Engine Coolant Temperature Gage
You have a gage that
shows the engine coolant
temperature. If the gage
pointer moves into the red
area, your engine is too hot!
That reading means the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.

2-66 Low Coolant Warning Light
If the LOW COOLANT light comes on, your system is
low on coolant and the engine may overheat. See
ªEngine Coolantº 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
The low tire inflation
monitor system can
alert you to a large
change in the pressure
in one tire.
After the system has ªlearnedº 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 low tire inflation
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 (110 km/h).
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 ªIf a Tire Goes Flatº in the Index.)
Also check the tire pressure in all four tires as soon as
you can. See ªInflation
- Tire Pressureº in the Index.
The light will stay on until you turn off the ignition or
reset the system. See ªLow Tire Inflation Monitor
Systemº in the Index.

2-67 Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (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.
NOTICE:
Modifications made to the engine, transaxle,
exhaust or fuel system of your vehicle or the
replacement of the original tires with other than
those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.

2-68
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.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

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 ªIf the Light Is On Steadyº 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 ªIf the Light
Is On Steadyº 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 recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. 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.

2-70 Low Oil Pressure 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:

The light will come on briefly when you turn on
the ignition to show you that is 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.CAUTION:
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 you oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

2-71 Low Oil Level Light
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 ªEngine Oilº in the Index.)
If the light does not come on briefly, 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
The CHANGE OIL SOON
light should come on briefly
as a bulb check when you
start the engine. If the
light doesn't come on,
have it serviced.
If the CHANGE OIL SOON light comes on and stays
on after you start the engine, have the oil changed.
For additional information, see ªEngine Oil, When to
Changeº in the Index. To reset the Oil Life Monitor,
see ªEngine Oil Life Monitorº in the Index.

2-72 Security Light
The SECURITY light will
come on when you turn the
key to START and stay on
until the vehicle starts.
It will also flash if your ignition key is too dirty or wet
for the PASS
-Key
II system to read the resistor pellet.
See ªPASS
-Key IIº in the Index.
If the resistor pellet is damaged or missing, the light will
come on.
Cruise Light
The CRUISE light comes
on whenever you set your
cruise control. See ªCruise
Controlº in the Index.
Performance Shift Light (If Equipped)
The PERF SHIFT light
comes on when you press
the performance shift
button to indicate that your
vehicle is in performance
shifting mode.
See ªPerformance Shiftingº in the Index.
Service Vehicle Soon Light
The SERVICE VEHICLE
SOON light will come on
if you have certain
non
-emission related
vehicle problems.
These problems may not be obvious and may affect
vehicle performance or durability. Consult a qualified
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.
