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.

Security Light
Your vehicle may have a
content theft-deterrent
alarm system. With
this system, the
SECURITY light will ¯ash
as you open the door
(if your ignition is off).
For more information see
Content Theft-Deterrent on
page 2-18.
Cruise Control Light
The CRUISE light comes
on when you set the
vehicle's cruise control.
See ªCruise Controlº under
Turn Signal/Multifunction
Lever on page 3-7.
Service Vehicle Soon Light
This light will come on and
stay on if your vehicle has
certain non-emission
related problems.
These problems may not be obvious and may affect
vehicle performance or durability. Consult a quali®ed
dealership for necessary repairs to maintain top vehicle
performance.
This light will come on brie¯y when the ignition is turned
on to show that it is working properly.
3-44

Fuel Gage
The fuel gage shows about how much fuel is in your
tank. It works only when the ignition is on. When
the indicator moves to the edge of the low fuel warning
band, the low fuel warning light will come on and a
chime will sound. You still have a little fuel left, but you
need to get more fuel right away.Here are some things that some owners 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 takes more (or less) fuel to ®ll up than the gage
indicated. For example, the gage may have
indicated half full, but it took more (or less) than
half the tank's capacity to ®ll it.
·The gage moves up a little when you turn a corner,
speed up or make a hard stop.
·The gage doesn't go back to empty when you turn
off the ignition.
Driver Information Center (DIC)
Your vehicle may be equipped with a Driver Information
Center (DIC). The DIC will display information about
how your vehicle is functioning, as well as warning
messages if a system problem is detected. This feature
also allows two different drivers to store and recall
their own personal choice settings. See ªDIC Controls
and Displaysº following for more information. United States

DIC Controls and Displays
When you turn the ignition on, the DIC will display your
DRIVER NUMBER. You can have your dealer
program your name to appear on this display line. See
your dealer for more information.
The system will then perform a status check and display
any messages if a problem is detected. If there are
no problems detected, the display will return to the mode
selected by that driver the last time the ignition was
turned off.
If a problem is detected, a diagnostic message will
appear in the display. The following pages will show the
messages you may see on the DIC display.

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.
