2005 BUICK LESABRE key

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. SeeTowing
Your Vehicle on page 4-36.
{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 have 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 3-38.
The anti-lock brake system warning light will come on
briey 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.

Notice:Modications 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.
Modications 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 does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions and
may damage the emission control system on your
vehicle. Diagnosis and service may be required.
Light On Steady— 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 “If
the Light Is On Steady” 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 “If
the Light Is On Steady” following. If the light is still
ashing, follow the previous steps and see your
GM dealer for service as soon as possible.

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, 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). SeeDIC Controls and
Displays on page 3-47.
The oil pressure light will come on briey 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 lightcomeson 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.

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 GM 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
are 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
will know that something has caused your vehicle to
start to spin, so you should consider slowing down.DIC Vehicle Personalization
