2003 BUICK LESABRE light

Traction Control System (TCS)
Warning Light
For vehicles equipped with
the traction control system,
this warning light should
come on brie¯y when
the engine is started.
If the warning light doesn't come on then, have it ®xed
so it will be ready to warn you if there's a problem.
If it stays on, or comes on when you're driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning
light is on, the system will not limit wheel spin. Adjust
your driving accordingly.The traction control system warning light may come on
for the following reasons:
·If you turn the system off by pressing the button
located on the end of the gearshift lever, the
warning light will come on and stay on. To turn the
system back on, press the button again. The
warning light should go off. See
Traction Control
System (TCS) on page 4-9for more information.
·If there's a brake system problem that is speci®cally
related to traction control, the traction control
system will turn off and the warning light will come
on. If your brakes begin to overheat, the traction
control system will turn off and the warning light will
come on until your brakes cool down.
·If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

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.
3-41

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
Filling Your Tank on page 5-7. 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.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-4. 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, mis®ring, 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,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to ®x 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 light is on or not working properly.
3-42

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.
3-43

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
Canada
3-45

DIC Vehicle Personalization
The DIC can be used to program the following personal
choice features available with your vehicle:
·Automatic Door Locks
·Window Lock Out
·Security Feedback
·Delayed Locking
·Perimeter Lighting
·Memory Seats
·Outside Curb View Assist Mirror
·Driver ID
·Language Selection
The personal choice settings displayed on the DIC are
determined by the transmitter used to enter the
vehicle. Each remote keyless entry transmitter was
pre-programmed to belong to DRIVER 1 or DRIVER 2
and is numbered on the back. After the unlock button on
a remote keyless entry transmitter is pressed and the
ignition is in RUN, the DIC will display the identi®ed
driver and recall the settings previously programmed for
that driver. The settings can also be recalled by
brie¯y pressing one of the MEMORY buttons located on
the driver's door.If you unlock the vehicle using your door key instead of
your transmitter, the DIC will not change drivers and
will recall the information from the last transmitter used
or the last driver using the memory seat controls. If
this happens and you were not the last driver of
the vehicle, simply press your correct driver number on
the memory seat controls or press the unlock button
on your remote keyless entry transmitter.
Use the following steps for personalization programming
instructions.
1. Turn the ignition on and keep the transaxle in
PARK (P).
2. Inform the DIC which driver you are by pressing the
unlock button on your remote keyless entry
transmitter or the appropriate memory seat control.
3. Press and hold the ENG/MET button for ®ve
seconds. WELCOME TO BUICK OPTION
FEATURE will appear in the display.
4. The ®rst choice to be made will be DRIVER
ID 1 or 2. Press the ENG/MET button to toggle
between your selections within a display and
RESET to choose the current selection and move
on to the next personal choice feature.
