2003 BUICK LESABRE ignition

When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake doesn't
release fully. If you try to drive off with the parking brake
set, a chime will also come on until you release the
parking brake. If the light stays on after your parking
brake is fully released, it means you have a brake
problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
¯oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. See
Towing
Your Vehicle on page 4-31.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you've pulled off the road and stopped
carefully, have the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light(s) will
come on when your engine
is started and may stay
on for several seconds.
That's normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you're driving, stop as soon
as possible and turn the ignition off. Then start the
engine again to reset the system. If the light still stays
on, or comes on again while you're driving, your vehicle
needs service. If the regular brake system warning
light isn't on, you still have brakes, but you don't have
anti-lock brakes. If the regular brake system warning
light is also on, you don't have anti-lock brakes
and there's a problem with your regular brakes. See
Brake System Warning Light on page 3-37.
The anti-lock brake system warning light will come on
brie¯y when you turn the ignition key to RUN. This
is normal. If the light doesn't come on then, have it ®xed
so it will be ready to warn you if there is a problem.

Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature. If the pointer
moves into the shaded
area, the engine is too hot.
A temperature indicator light will turn on and a chime
will sound.
If you have been operating your vehicle under normal
driving conditions, and the temperature indicator
light comes on, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
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.
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. Standard version
shown, uplevel similar
3-40

Notice:Modi®cations made to the engine,
transaxle, exhaust, intake 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 this light to come on.
Modi®cations 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.
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 FlashingÐ A mis®re condition has been
detected. A mis®re increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
·Light On SteadyÐ An emission control system
malfunction has been detected on your vehicle.
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 ¯ashing and remains on steady, see ªIf
the Light Is On Steadyº following.
If the light continues to ¯ash, 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
¯ashing, follow the previous steps, and see your dealer
for service as soon as possible.

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 message center is continuously updated with the
vehicle's performance status.The following buttons are
on the DIC control panel
which is located to
the left of the steering
column:
ODO/TRIP (Odometer/Trip):When this button is
pressed, the display will show the total mileage, and
Trip 1 or Trip 2 miles. Trip 1 and Trip 2 will display the
miles traveled since the last reset. To reset the trip
odometer, press the ODO/TRIP button until the preferred
trip number (1 or 2) is shown in the DIC display, then
press the RESET button. The trip odometer will

If you would like to exit the selection mode without
moving through each of the personal choice features,
simply press a different button on the DIC or turn off the
ignition. Whatever personal choices you made will
still be retained, even without passing through each of
the features. In order for your personal choices to save,
you must press RESET after making your selections.
If you happen to move past a selection you would like to
make a personal choice for, press the unlock button
on your remote keyless entry transmitter or press
