2000 PONTIAC BONNEVILLE warning light

2-71 Tire Pressure Light (If Equipped)
The check tire pressure
system can alert you to
a large change in the
pressure of one tire.
After the system has been properly calibrated, the
TIRE PRESS light will come on if a pressure difference
(low pressure) is detected in one tire.
The light will stay on until you turn off the ignition or
reset (calibrate) the system. See ªCheck Tire Pressure
Systemº in the Index.
The TIRE PRESS light also comes on briefly when you
turn your ignition key to START. 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.
If the anti
-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. (Also, see
ªAnti
-Lock Brake System Warning Lightº in the Index).
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 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.

Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to
help your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON light is on or not
working properly.
Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.
Oil Pressure Gage
United States Canada
Readings above the red warning zone indicate the
normal operating range. Oil pressure may vary with
engine speed, outside temperature and oil viscosity.
A reading in the red warning zone may be caused by
a low oil level or another problem causing low oil
pressure. On vehicles with the systems monitor, the
CHECK GAGES light will come on and a warning
chime will sound.

2-75
On vehicles with the optional DIC, a CHECK GAGES
OIL PRESSURE message will be displayed and a
warning chime will sound. See ªDIC Warnings and
Messagesº in the Index for more information.
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 your 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.

light is part of the systems
monitor. This light comes
on for five seconds as a bulb
check each time the ignition
key is turned to RUN.
If the engine oil is more than 1 quart (0.95 L) low and
the engine has been shut off for at least eight minutes,
the CHECK OIL LEVEL light will come on and a
chime will sound the next time you start your vehicle.
If the CHECK OIL LEVEL light comes on, the engine
oil level should be checked at the dipstick then brought
up to the proper level, if necessary. See ªEngine Oilº in
the Index.
On vehicles with the optional DIC, the CHECK OIL
LEVEL light is replaced by an OIL LEVEL LOW
message. See ªDIC Warnings and Messagesº in the
Index for more information.

2-76
Service Vehicle Soon Light (If Equipped)
This light will come on
briefly as a bulb check
when your ignition is

-emissions related vehicle
problem. These problems may not be so obvious and
may not affect vehicle performance or durability.
Consult a qualified dealership for necessary repairs to
maintain top vehicle performance.
On vehicles with the supercharged engine and the
optional DIC, the SERVICE VEHICLE SOON light is
replaced by the SERVICE VEHICLE SOON message.
See ªDIC Warnings and Messagesº in the Index for
more information.
Low Washer Fluid Warning Light
(If Equipped)
This light is part of the
systems monitor. It will
come on and a warning
chime will sound when the
washer fluid container is
less than one
-third full.
On vehicles with the optional DIC, the WASHER
FLUID light is replaced by the WASHER FLUID LOW
message. See ªDIC Warnings and Messagesº in the

Fuel Gage
United States Canada
When the ignition is on, your fuel gage tells you about
how much fuel you have in your tank.When the gage reads in the yellow band, a warning
chime will sound and the CHECK GAGES warning
light will come on. You still have a little fuel left, but
you need to get more fuel right away.
On vehicles with the optional DIC, the CHECK GAGES
LOW FUEL message will be displayed when the fuel
gage reads in the yellow band. See ªDIC Warnings and
Messagesº in the Index for more information.
Here are some things that owner's ask about. None of
these show a problem with your fuel gage:

At the service station, the gas pump shuts off before
the gage reads full.

It take a little more (or less) fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more (or less) than half the tank's capacity to
fill the tank.

2-79 Boost Gage (If Equipped)
Vehicles equipped with
the supercharged engine
have this boost gage that
indicates vacuum during
light to moderate
throttle and boost under
heavier throttle.
The gage displays the air pressure level going into the
engine's combustion chamber.
The gage is automatically centered at zero every time
the ignition key is turned to RUN. Actual vacuum or
boost is displayed from this zero point. Changes in
ambient pressure, such as driving in mountains and
changing weather, will slightly change the zero reading.
Head-Up Display (Option)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If you have the optional Head-Up Display (HUD), you
can see some of the driver information also available on
your instrument panel cluster. The information may be
displayed in English or metric units and appears as a
reflection on the windshield. The HUD shows:

Speedometer Reading

Turn Signal Indicators

High
-beam Indicator Symbol

CHECK GAGES Message (for low oil pressure,
high coolant temperature, low oil level, high/low
battery, brake, ABS and air bag.)

Low Fuel Warning Symbol

Radio Frequency and Playback Mode

2-80
HUD shows these images when they are lighted on the
instrument panel.
The speedometer may display a difference of 1 mph
(1.6 km/h) from the HUD image. This is normal.
When the ignition key is turned to RUN, all possible
HUD images will come on, then the HUD will
operate normally.If you never look at your instrument panel cluster, you
may not see something important, such as a warning
light. So be sure to scan your displays and controls and
the driving environment just as you would in a vehicle
without HUD.
NOTICE:
Although the HUD image appears to be near the
front of the vehicle, do not use it as a parking aid.
The HUD was not designed for that purpose.
If you try to use it that way, such as in a
parking lot, you may misjudge distance and
run into something.
