You will see this light flash for a few seconds when you
turn your ignition to
“Run” or “Start.” Then the light
should
go out, which means the system is ready.

How The Air Bag System Works
Where is the air bag?
The driver’s air bag is in the middle of the steering
wheel.
When is an air bag expected to inflate?
The air bag is designed to inflate in moderate to severe
frontal or near-frontal crashes. The air bag will only
inflate if the velocity
of the impact is above the designed
34

nitrogen gas used to inflate the air bag will have vented
into the passenger compartment, and the bag will be
deflated within seconds after
the collision. Nitrogen
makes up about
80% of the air we breathe and is not
hazardous.
As the nitrogen vents from the bag, small
particles are also vented into the passenger
compartment.
A CAUTION:
’
0
I’
Don’t attach anything to the steering wheel
pad.
It might injure the driver if the air bag
inflates.
The air bag
is designed to inflate only once.
After
it 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 the air bag module and
possibly other parts. The service manual
has information about the need to replace
other
parts.
Let only qualified technicians work on your
air-bag system. Improper service can mean
I
.‘that your air bag system won’t work
properly.
See your dealer fgr service.
Servicing Your Buick with the Air Bag
System
Please tell or remind anyone who works on your Buick
that
it has the air bag system. There are parts of the air
bag system
in several places around your vehicle. You
don’t want the system to inflate while someone is
working on your vehicle. The air bag system does not
need regular maintenance, Your Buick dealer and the
1993 LeSabre Service Manual have information about
the air bag system, including repair or disposal.
A CAUTION:
For up t0.2 minutes after the ignitlon key is
turned off and the battery 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. Be sure
to follow the proper service
procedures.
When electrical work is done under the hood or inside
your vehicle, the ignition should be
in “Lock” if
possible.

Operation
The
driver’s door will unlock when UNLOCK is
pressed.
If pressed again quickly, all doors will unlock.
All doors will lock when LOCK is pressed. The trunk will unlock when the opened trunk symbol
is pressed,
but only when the ignition is

Matching Transmitter(s) To Your Vehicle
Each key chain 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 the remaining
transmitter with
you when you go to your dealer. When
the dealer matches the replacement transmitter to your
vehicle,
the remaining transmitter must also be matched.
Once the new transmitter
is coded, the lost transmitter
will not unlock your vehicle.
You can match a transmitter
to as many different
vehicles as you own, provided they are equipped with
exactly
the same model system. (General Motors offers
several different models of these systems on their
vehicles.) Each vehicle can have only two transmitters
matched to
it.
To match a transmitter, use the following instructions,
1. Have both transmitters that will be matched to the
car present, even if only one is new. Remove the car
keys from
the ignition and have them with you.
2. Find the 12 pin diagnostic connector above the
accelerator pedal.
