just push the button
on the buckle.

the door on it, you can damage both the belt and your vehicle.
SUPPLEMENTL INFUTABLE
RESTMNT SYSTEM
(AIR BAGS)
This section explains the Supplemental Inflatable Restraint (SIR), or “air
bag,” system. Your Cadillac has an air bag for both the driver and the
right-front passenger.
Here’s the most important thing to know:

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument panel, which has
“INFL REST.” or “INFLATABLE RESTRAINT” on it. The system
checks for electrical malfunctions, and the light tells you
if there is a
problem.
INFLATABLE
RESTRAINT
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.
Remember,
if the air bag readiness light doesn’t come on when you start
your vehicle, or stays on,
or comes on when you are driving, your air bag
system may not work properly. Have your vehicle serviced right away.

Where is the air bag?
The driver’s air bag is in the middle of the steering wheel. The right-front
passenger’s air bag
is located in the instrument panel on the passenger’s side.

Downloaded from www.Manualslib.com manuals search engine 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 threshold level. When impacting straight
into a wall that does not move or deform, the threshold level for most
GM vehicles is between 9 and 15 mph (14 and 23 km/h). However, this
velocity threshold depends on the vehicle design and may be several
miles-per-hour faster or slower. In addition, this threshold velocity will be
considerably higher if the vehicle strikes an object such as a parked car
which will move and deform on impact.
The air bag is also not designed
to inflate in rollovers, side impacts, or rear impacts where the inflation
would provide no occupant protection benefit.
The air bag sensing system uses separate triggering paths to assure that
sufficient electrical current is available to inflate both air bags. The air
bags inflate in rapid succession. However,
in crashes just above the air
bag deployment threshold, it is possible that the triggering signal may
only last long enough to deploy either the driver or passenger air bag, but
not both. Air bags are least needed in these crashes. In severe frontal and
near-frontal crashes
-- in which air bags provide the most benefit -- the
separate triggering paths help assure that both air bags always inflate.
In any particular crash, the determination of whether the air bag should have
inflated cannot be based solely on the level
of damage on the vehicle@).
Inflation is determined by the angle of the impact and the vehicle’s
deceleration,
of which vehicle damage is only one indication. Repair cost is
not a good indicator
of whether an air bag should have deployed.

Downloaded from www.Manualslib.com manuals search engine What makes an air bag inflate?
In a frontal or near-frontal impact of sufficient severity, the air bag
sensing system detects that the vehicle is suddenly stopping as a result
of
a crash. The sensing system triggers a chemical reaction of the sodium
azide sealed in the inflator. The reaction produces nitrogen gas, which
inflates a cloth bag. The inflator, cloth bag, and related hardware are all
part
of the air bag inflator modules packed inside the steering wheel and
in the instrument panel in front
of the passenger.
How does an air bag restrain?
In moderate to severe frontal or near-frontal collieions, even belted
occupants can contact the steering wheel or the instrument panel. The air
bag supplements 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
provide protection in many types of collisions, including rollovers and
rear and side impacts, primarily because an occupant’s motion is not
toward the air bag. Air bags should never be regarded as anything more
than a supplement to safety belt protection in moderate to severe frontal
and near-frontal collisions.
What will you see after an air bag inflation?
After the air bag has inflated, it will then quickly deflate. This occurs so
quickly that some people may not even realize that the air bag inflated.
Some components of the air bag module in the steering wheel hub for the
driver’s air bag or the instrument panel for the passenger’s bag may be
hot for a short time, but the portion of the bag that comes into contact
with you will not be hot
to the touch. There will be small amounts of
smoke and dust coming from vents in the deflated air bags. The air bag
will
not impede the driver’s vision or ability to steer the vehicle, nor will it
hinder the occupants from exiting the vehicle.

Downloaded from www.Manualslib.com manuals search engine In many crashes severe enough to inflate an air bag, windshields are
broken by vehicle deformation. Additional windshield breakage may
occur in vehicles with passenger air bags because the windshield acts as a
reaction surface for the inflating air bag.

The 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 has information about the need to replace other parts.
Your vehicle is equipped with a diagnostic module, which records
information about the air bag system if the air bag deploys in a crash.
The module records information about the readiness
of the system,
which sensors activated the deployment, and whether the driver’s
safety belt was in use.
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 cover for the driver’s or the right-front
passenger’s air bag, they may not work properly.
You may have
to replace the air bag on the steering wheel or both the air bag
and the instrument panel for the passenger‘s air bag.
Do not
open or break the air bag covers.
