How the Air Bag System Works
Where are the air bags?
The driver's air bag is in the middle of the steering wheel. The right front passenger's air bag is
in the instrument
panel on the passenger's side.

If something is between an occupant and an air
bag, the bag might not inflate properly or it
might force the object into that person. The path
*of an inflating air bag must be kept clear. Don’t
put anything between an occupant and
an air
bag, and don’t attach or put anything on the
steering wheel hub
or on or near any other air
bag covering.
When should
an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near-frontal crash. The
air bag will inflate
only
if the impact speed is above the system’s designed
“threshold level.”
If your vehicle goes straight into a
wall that doesn’t move or deform, the threshold level is
about
9 to 15 mph (14 to 24 km/h). The threshold level
can vary, however, with specific vehicle design,
so that
it can be somewhat above or below this range. If your
vehicle strikes something that will move or deform, such
as a parked car, the threshold level
will be higher. The
air bag is not designed to inflate in rollovers, side
impacts or rear impacts, because inflation would not
help the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply bqause of the damage
to a vehicle or because of what the‘repair costs were.
Inflation is determined by the angle of the impact and
how quickly the vehicle slows down in frontal or
near-frontal impacts.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. The sensing
system triggers a release of gas from the inflator, which
inflates the air bag. The inflator, air bag and related
hardware are all
part of the air bag modules inside the
steering wheel and in the instrument panel in front of the
right front passenger.

How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Air bags supplement the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. But air bags would
not help you in many types of collisions, including
rollovers, rear impacts and side impacts, primarily
because an occupant’s motion is not toward those air
bags. Air bags should never be regarded as anything
more than a supplement
to safety belts, and then only in
moderate to severe frontal or near-frontal collisions.
What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so
quickly that some people may not even realize the
air bag inflated. Some components of the air bag
module
-- the steering wheel hub for the driver’s
air bag, or the instrument panel for the right front
passenger’s bag
-- will be hot for a short time. The
parts of the bag that come into contact with you may
be warm, but not
too hot to touch. There will be some
smoke and dust coming from vents
in the deflated air
bags. Air bag inflation doesn’t prevent the driver from
seeing or from being able to steer the vehicle, nor does
it stop people from leaving
the vehicle.
I-
When an air bag i. ates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as it
is safe to do so.
If you have breathing problems but can’t get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window
or door.
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 they
inflate, 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 a crash sensing and
diagnostic module, which records information about
the
air bag system. The module records information
about the readiness
of the system, when the sensors
are activated and driver’s safety belt usage at
deployment.
Let only qualified technicians work on your air
bag system. Improper service can mean that your
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, the bag may not
work properly. You may have to replace the air
bag module in the steering wheel or both the
air
bag module and the instrument panel for the
right front passenger’s
air bag. Do not open or
break the
air bag coverings.
Servicing Your Air Bag-Equipped Buick
Air bags affect how your Buick should be serviced.
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. Your
Buick dealer and the Century Service Manual have
information about servicing your vehicle and the air bag
system. To purchase a service manual, see “Service and
Owner Publications” in the Index.
I
For up to 10 minutes 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 wires wrapped with yellow tape
or yellow connectors. They are probably
part of
the air bag system.
Be sure to follow proper
service procedures, and make sure the person
performing work for you
is qualified to do so.
The air bag system does not need regular maintenance.

Trunk Lock
To unlock the trunk from
the outside, insert the door
key and turn
it. You can also
press the car symbol on
your remote keyless
entry transmitter.
Theft
Vehicle theft is big business, especially in some cities.
Although your Buick has a number
of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways
you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do it. When
you park your Buick and open the driver’s door,
you’ll hear
a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transaxle. And remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them
in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it’s best
to lock it up and take your keys.
But what if
you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your trunk
or glove
box.
0 Lock the glove box.
0 Lock all the doors except the driver’s.
0 Then take the door key and remote keyless entry
transmitter with
you.

New Vehicle “Break-In”
NOTICE:
Your modern Buick doesn’t need an elaborate
“break-in.” But it will perform better in the long
run if you follow these guidelines:
0 Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don’t make full-throttle starts.
200 miles (322 km) or so. During this time
your new brake linings aren’t yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement. Follow this breaking-in guideline every
time you get new brake linings.
See “Towing
a Trailer’’ in the Index for
more information.
Avoid making hard stops for the first
0 Don’t tow a trailer during break-in.
Ignition Positions
A L
With the ignition key in the ignition switch, you can turn
the switch
to five positions:
ACC
(A): This position lets you use the radio and
windshield wipers when the engine is off. To use
ACC
(Accessory), push in the key and turn it toward you.
Your steering wheel will stay locked.
2-17
ProCarManuals.com

LOCK (B): Before you put the key into the ignition
switch, the switch is in
LOCK. It’s also the only position
from which you
can remove your key. This position
locks your ignition, steering wheel and transaxle. It’s
a
theft-deterrent feature.
OFF (C): This position lets you turn off the engine but
still turn
the steering wheel, It doesn’t lock the steering
wheel like
LOCK. Use OFF if you must have your
vehicle pushed or towed.
RUN (D): This position is where the key returns after you
start your vehicle. With the engine off, you can use RUN
to display some of your warning and indicator lights.
START (E): This position starts your engine.
A warning chime will sound if you open the driver’s
door when the ignition is
in OFF, LOCK or ACC and
the key is in the ignition.
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. But 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.
In case you cannot remove
your key from the ignition,
find the access
slot which is located underneath the
steering column below the lock cylinder.
To use this slot, remove the trim cap. Insert
a key or
screwdriver into the access slot and rotate the lock
cylinder.
You will now be able to remove your key from
the ignition. Be sure to replace the trim cap after use.
