BUICK LESABRE 2002 Owner's Manual

2-78
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.
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 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 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 ªDIC Displays and
Controlsº in the Index.
The oil pressure light will come on briefly 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 fixed so it will be there to warn you if there is
a problem.

2-80
When this light comes on and stays on, 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 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.
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 qualified
dealership for necessary repairs to maintain top
vehicle performance.
This light will come on briefly when the ignition is
turned on to show that it is working properly.
Security Light
Your vehicle may have
a content theft
-deterrent
alarm system. With this
system, the SECURITY
light will flash as you open
the door (if your ignition
is off).
For more information see ªContent Theft
-Deterrentº in
the Index.

2-81 Cruise Light
The CRUISE light comes
on when you set the
vehicle's cruise control.
See ªCruise Controlº
in the Index.
Fuel Gage
United States CanadaThe 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 fill 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 fill 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.

2-82
Driver Information Center (DIC)
(If Equipped)
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 Personal Choice Programmingº later in
this section.
DIC Displays and Controls
There are two lines in the DIC display. The DIC
displays the driver number identified when entering the
vehicle. You can have your dealer program your name to
appear on this display line. See your dealer for more
information.
When you turn the ignition on, the DIC will display
your DRIVER NUMBER. 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 now accumulate miles until the next reset.

is viewed as a long term approximation of your overall
driving conditions. To learn the average fuel economy
from a new starting point, press the RESET button while
the average fuel economy is displayed in the DIC.
Press the FUEL INFO button until the display
shows FUEL ECONOMY INST. Instantaneous fuel
economy varies with your driving conditions, such as
acceleration, braking and the grade of the road being
traveled. The RESET button does not function in
this mode.
Press the FUEL INFO button until the display shows
FUEL RANGE. The fuel range will calculate the
remaining distance you can drive without refueling. This
calculation is based on the average fuel economy for 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

is 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.

according to the maintenance schedule (see
ªMaintenance Scheduleº in the Index), you will have to
reset the oil life monitor. To reset the Oil Life System
(Index), see ªOil Life Systemº or ªEngine Oil, When to
Changeº in the Index.
Press the GAGE INFO button until TIRE PRESSURE
appears in the display. TIRE PRESSURE NORMAL is
displayed when the check tire pressure system believes
your vehicle's tire pressures are normal. If a potential
tire pressure problem is detected, the display will show
CHECK TIRE PRESSURE.If you see the CHECK TIRE PRESSURE message, you
should stop as soon as you can and check all your tires
for damage. (If a tire is flat, see ªIf a Tire Goes Flatº in
the Index.) Also check the tire pressure in all four tires
as soon as you can. See ªInflation
-- Tire Pressureº
and ªCheck Tire Pressure Systemº in the Index.
There are times when you will have to reset (calibrate)
the Check Tire Pressure System. See ªCheck Tire
Pressure Systemº in the Index.
RESET: This button, used along with other buttons, will

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.

2-86
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.
DIC Personal Choice Programming
The DIC can be used to program the following personal
choice features available with your vehicle:

Automatic Door Locks

Window Lockout

Security Feedback

Delayed Locking

Perimeter Lighting

Memory Seats (If Equipped)

Tilt Mirrors (If Equipped)

Driver ID ON/OFF

Language SelectionFor vehicles not equipped with a DIC, see ªPersonal
Choice Programmingº in the Index.
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 button with the
unlock symbol on a remote keyless entry transmitter is
pressed and the ignition is in RUN, the DIC will display
the identified driver and recall the settings previously
programmed for that driver. The settings can also be
recalled by briefly 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 button with the unlock symbol
on your remote keyless entry transmitter.
