low oil pressure BUICK LESABRE 2003 Owner's Manual

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, your GM dealer can prepare the
vehicle for inspection.
Oil Pressure Light
If your vehicle has the
standard instrument panel
cluster, this light will
come on if there is a
problem with your vehicle's
engine oil pressure.
If your vehicle has the optional gage cluster, you can
read your oil pressure directly from the Driver
Information Center (DIC). See
DIC Controls and
Displays on page 3-46.The oil pressure light will come on brie¯y when you turn
your key to RUN. That's just a check to be sure the
light works. This is normal and doesn't show a problem.
If it doesn't come on and then go off, be sure to have
it ®xed so it will be there to warn you if there is a
problem.
When this light
comeson andstayson, and a chime
sounds, it means oil isn't going through the engine
properly. The oil could be low, or there might be some
other oil problem. See your dealer for service.
{CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches ®re. 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.

the last 25 miles (40.25 km) driven, and the fuel
remaining in the fuel tank. The RESET button does not
function in this mode.
GAGE INFO (Information):Use this button to display
oil pressure, oil life, coolant temperature, tire pressure
and battery information.Press the GAGE INFO button until OIL PRESSURE
appears in the display. If there are no problems detected
with the oil pressure, the display will show OIL

detected, the display will show OIL PRESSURE
LOW. If you see the OIL PRESSURE LOW message,
your vehicle could be low on oil or the oil is not
going through the engine properly. See your dealer for
service.
Press the GAGE INFO button until COOLANT TEMP
appears in the display. If there are no problems detected
with the temperature, COOLANT TEMP NORMAL will
appear in the display. If the temperature is too high,
COOLANT TEMP HOT will appear in the display. If you

your vehicle and turn off your engine as soon as
possible. This manual explains what to do. See
Engine

Pressing any of the DIC control buttons will remove
the messages or warnings from the DIC display.SERVICE STABILITY SYSTEM ± 54:If you ever see
the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system (stop; turn off the engine; then start the
engine again). If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem.
You should see your dealer for service. Reduce
your speed and drive accordingly.
STABILITY SYSTEM ACTIVE ± 55:You may see the
STABILITY SYSTEM ACTIVE message on the Driver
Information Center. It means that an advanced,
computer-controlled system has come on to help your
vehicle continue to go in the direction in which you're
steering. This stability enhancement system activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of ice or
other slippery spot on the road. When the system is on,
you may hear a noise or feel a vibration in the brake
pedal. This is normal.
When the STABILITY SYSTEM ACTIVE message is on,
you should continue to steer in the direction you want
to go. The system is designed to help you in bad
weather or other difficult driving situations by making the
most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on, you'll
know that something has caused your vehicle to start
to spin, so you should consider slowing down.

.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
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.
The engine oil dipstick is
located right behind the
engine fans and in front of
the engine oil ®ller cap.
The top of the dipstick is a
round yellow loop. See
Engine Compartment
Overview on page 5-12for
more information on
location.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil
dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
