A CAUTION:
Air bags inflate with great force, faster than the blink of an eye.
If yoii’re too close to an inflating air bag, it could seriously
injure
you. Safety belts help keep you in position for an air bag
inflation in a crash. Always wear your safety belt, even with an
air bag, and sit as
far back as you can while still maintaining
control
of your vehicle,
Air Bag System Light
There is an air bag readiness light on the instrument panel, which shows
“Inflatable Restraint”. The system checks itself and the light tells you if
there
is a problem.
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.
A CAUTION:
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.
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 14 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.
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(s). 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 impact of sufficient severity, sensors strategically located on
the vehicle detect that the vehicle
is suddenly stopping as a result of a
reaction of the sodium azide sealed in the inflator. The reaction produces
nitrogen gas, which inflates the cloth bag. The inflator, cloth bag, and
related hardware are all part of the air bag inflator module packed inside
the steering wheel.

How does an air bag restrain?
occupants can contact the steering wheel. The air bag supplements the
protection provided by safety belts. Air bags distribute the force of 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.
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. There

Some components
of the air bag module in the steering wheel hub 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. The 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

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 that your air bag system won’t
work properly. See your dealer for sewice.

Sewicing Your Cadillac with the Air Bag System
Please tell or remind anyone who works on your Cadillac that it has the c)
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 Cadillac dealer and the
1993 Cadillac Service Manual
have information about the air bag system, including repair or disposal.

A CAUTION:
For up to 2 minutes after the ignition 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.

bag readiness light on the instrument panel.
If you don’t see this light
