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.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. See
ªFilling Your Tankº in the Index. It will take a few
driving trips to turn the light off.

2-94
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
ªFuelº 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.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 or CHECK ENGINE
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
5.7L V8 Engine shown
3800 V6 Engine similarCanada
5.7L V8 Engine shown
3800 V6 Engine similar
This gage tells you if there could be a problem with your
engine oil pressure. The gage shows the engine oil
pressure in psi (pounds per square inch) or kPa
(kilopascals) when the engine is running.
On the 3800 V6 engine, the oil pressure should be
20 to 120 psi (140 to 827 kPa). On the 5.7L V8 engine,
oil pressure should be 20 to 80 psi (140 to 550 kPa).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still be
considered normal.It may vary with engine speed, outside temperature and
oil viscosity, but readings above the red area show the
normal operating range. Readings in the red area tell
you that the engine is low on oil, or that you might have
some other oil problem. See ªEngine Oilº in the Index.
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.

2-96 Low Oil Light
This warning light should
come on briefly while you
are starting your engine.
If the light doesn't come on,
have it repaired.
If the light stays on after starting your engine, your
engine oil level may be too low. You may need to add
oil. See ªEngine Oilº in the Index.
NOTICE:
The oil level monitoring system only checks
the oil level when you are starting your engine.
It does not keep monitoring the level once the
engine is running. Also, the oil level check only
works when the engine has been turned off long
enough for the oil to drain back into the oil pan.
Oil Change Light
This OIL CHANGE light
should come on briefly as a
bulb check when you start
the engine. If the OIL
CHANGE light doesn't
come on, have it serviced.
If the OIL CHANGE light comes on and stays on

oil changed.
For additional information, see ªEngine Oil, When to
Changeº in the Index. After changing the engine oil, the
system must be reset. See ªHow to Reset the Oil Change
Lightº in the Index.
