2001 BUICK LESABRE replace battery

1-27
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.

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 or
resynchronization is necessary. See the instructions
that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
The numbers on the back of your transmitter correspond to
DRIVER #1 and DRIVER #2 on the DIC (if equipped).
For more information see ªDICº 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.

2-14 Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.
See your dealer to have additional transmitters matched
to your vehicle.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.

2-15
For battery replacement, use one Duracell
battery,
type DL
-2032, or a similar type.To replace the battery, do the following:
1. Insert a coin into the notch near the key ring.
Turn the coin counterclockwise to separate the
two halves of the transmitter.
2. Once the transmitter is separated, use a pencil eraser
to remove the old battery. Do not use a metal object.
3. Remove and replace the battery. Replace it as the
instructions inside the cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Check the operation of the transmitter.

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 any 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.

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.

Jump Starting
If your vehicle's battery has run down, you may want to
use another vehicle and some jumper cables to start your
vehicle. But please use the following steps to do it safely.
You will not see the battery under the hood of your
vehicle, since it is located under the rear seat on the
passenger's side.
CAUTION:
Batteries can hurt you. They can be
dangerous because:

They contain acid that can burn you.

They contain gas that can explode or ignite.

They contain enough electricity to
burn you.
If you don't follow these steps exactly, some or all
of these things can hurt you.
NOTICE:
Ignoring these steps could result in costly
damage to your vehicle that wouldn't be covered
by your warranty.
The ACDelco battery in your vehicle has a
built
-in hydrometer. Do not charge, test or jump
start the battery if the hydrometer looks clear or
light yellow. Replace the battery when there is a
clear or light yellow hydrometer and a
cranking complaint.
Trying to start your vehicle by pushing or pulling
it won't work, and it could damage your vehicle.
