service BUICK LESABRE 2002 Owner's Manual

1-28
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inflate (if battery power is available). You can lock
the doors again and turn the interior lamps off by using
the door lock and interior lamp controls.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.

Air bags are designed to inflate only once. After an
air bag inflates, you'll need some new parts for your
air bag system. If you don't get them, the air bag
system won't be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for your
vehicle covers the need to replace other parts.

Your vehicle is equipped with an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also equipped
with a crash sensing and diagnostic module, which
records information about the frontal air bag system.The module records information about the readiness
of the system, when the system commands air bag
inflation and driver's safety belt usage at
deployment. The module also records speed,
engine rpm, brake and throttle data.

Let only qualified technicians work on your air bag
systems. Improper service can mean that an air bag
system won't work properly. See your dealer for service.
NOTICE:
If you damage the covering for the driver's or
the right front passenger's air bag, or the air
bag covering on the driver's and right front
passenger's seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger's air bag, or both the air bag
module and seatback for the driver's and right
front passenger's side impact air bag. Do not
open or break the air bag coverings.

1-29 Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
air bag systems. To purchase a service manual, see
ªService and Owner Publicationsº in the Index.
CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag systems. Be sure to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do so.
The air bag systems do not need regular maintenance.
Center Front Passenger Position

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the left
or right, hold the transmitter higher, and try again.

Check to determine if battery replacement is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or
a qualified technician for service.Operation
If your vehicle is equipped with the DIC, the numbers
on the back of your transmitter correspond to
DRIVER #1 and DRIVER #2 on the DIC. For more
information see ªDriver Information Center (DIC)º in
the Index.
When the unlock symbol is
pressed, the driver's door
will unlock and the exterior
lights will flash twice.
If the unlock symbol is pressed again within five
seconds, all doors will unlock, the exterior lamps will
flash twice and the horn may sound. See ªSecurity
Feedbackº in the Index.
Pressing the unlock symbol button will also illuminate
the interior lamps. See ªIlluminated Entryº in the Index.

2-19
If a door is opened without the key or remote
keyless entry transmitter, the alarm will go off.
Your vehicle's lamps will flash and the horn will
sound for 30 seconds. The lamps and horn will
then turn off to save battery power.
Remember, the content theft
-deterrent system won't
activate if you lock the doors with a key or use the
manual door lock. It activates only if you use a power
door lock switch with a door open, or with the remote
keyless entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key
if the alarm has been set off.
Here's how to avoid setting off the alarm by accident:

If you don't want to activate the theft
-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.

Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm
by pressing the button with the unlock symbol on the
remote keyless entry transmitter. The alarm won't stop
if you try to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, roll down the driver's
window and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the car, close the door and wait for the
SECURITY light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should, but the
vehicle's lamps flash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse, see
ªFuses and Circuit Breakersº in the Index.
If the alarm does not sound or the vehicle's lamps do
not flash, the vehicle should be serviced by an
authorized service center.

PASS-Key
III
Your vehicle is equipped
with the PASS
-Key III
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key III is a passive
theft
-deterrent system. This
means you don't have to do
anything different to arm or
disarm the system. It works
when you insert or remove
the key from the ignition.
Your PASS
-Key III system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired operation.This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS
-Key III uses a radio frequency transponder in the
key that matches a decoder in your vehicle.
When the PASS
-Key III system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
When trying to start the vehicle if the engine does not
start and the SECURITY light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.

2-21
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse (see ªFuses and
Circuit Breakersº in the Index). If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does start, the first key may be faulty.
See your dealer who can service the PASS
-Key III to
have a new key made.
It is possible for the PASS
-Key III decoder to learn the
transponder value of a new or replacement key. Up to
10 additional keys may be programmed for the vehicle.
This procedure is for learning additional keys only.
Canadian Owners: If you lose or damage your keys,
only a GM dealer can service PASS
-Key III to have new
keys made. To program additional keys you will need
two current driver's keys. You must add a step to the
following procedure. After Step 2, repeat Steps 1 and 2
with the second current driver's key. Then continue
with Step 3.To program the new key, do the following:
1. Verify that the new key has ªPK3º stamped on it.
2. Insert the current driver's key in the ignition and
start the engine. If the engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
5. The SECURITY telltale light will turn off once the
key has been programmed. It may not be apparent
that the SECURITY light went on due to how
quickly the key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the SECURITY light
comes on and stays on, you will be able to restart your
engine if you turn it off. Your PASS
-Key III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS
-Key III system at this time.
If you lose or damage a PASS
-Key III key, see your
dealer to have a new key made.

2-23
(B) LOCK: This is the only position in which you
can remove the key. This position locks your ignition,
steering wheel and transaxle. It's a theft
-deterrent feature.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. Turn the key only with your hand.
Using a tool to force it could break the key or
the ignition switch. If none of this works, then
your vehicle needs service.
(C) OFF: This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK and it doesn't send any electrical
power to the accessories. The instrument panel cluster
will remain powered in LOCK to illuminate the gear
shift indicator. The cluster will also activate the parking
brake light when the parking brake is set. Use UNLOCK
if you must have your vehicle in motion while the
engine is not running.(D) RUN: This is the position the switch returns to after
you start your engine and release the switch. This is also
the position for normal driving. Even when the engine is
not running, you can use RUN to operate your power
accessories and to display some instrument panel
warning lights.
(E) START: This position starts your engine. When
the engine starts, release the key. The ignition switch
will return to RUN for normal driving.
Key Reminder Warning
If you leave your key in OFF, you will hear a warning
chime when you open the driver's door.
Always leave your key in LOCK. If you leave it in any
other position, you will drain your battery power.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key,
you will still have power to such accessories as the
power windows, audio steering wheel controls
(if equipped), clock, sunroof (option) and the radio
for up to 10 minutes. The instrument panel cluster
lights will stay on for a few seconds, then will go out.
Once you open a door, the power will shut off.
