For the 1948 model, Cadillac
introduced the I
which set the trend in automotive
styling €or nearly two decades.
This
was followed by the 1949 model with
the two door hardtop Coupe DeVille

high compression V8 engine.
Engineering innovations, con-
veniences and styling dominated the
'50s and '60s. Cruise control, auto-
matic climate control,
tilt and
telescoping steering wheels, twilight
sentinel and four door hard tops
all
debuted in these years. In 1957 the
Eldorado Brougham featured

An Air Cushion Restraint Sys-

1975 and 1976 Cadillacs.
Analog Electronic Fuel Injec-

1975 Cadillacs

national size 1976 Seville. In

the Trip Computer option incor-

How The Air Bag System Works
.l
n
r
Where is the air bag?
The driver’s air bag is in the middle of the steering wheel. Your vehicle
has a front passenger air bag, it is located in the instrument panel on the
passenger’s side.
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 kmk). 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

Downloaded from www.Manualslib.com manuals search engine 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. 2-
_I What makes an air bag inflate?
In a frontal or near-frontal impact of sufficient severity, sensors
- strategically located on the vehicle detect that the vehicle is suddenly
stopping as a result of a crash. These sensors complete an electrical
circuit, triggering 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 collisions, 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
and near-frontal collisions.
What will you see after an air bag inflation?
__ than a supplement to safety belt protection in moderate to severe frontal
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
will be small amounts of smoke coming from vents in the deflated air
bags. 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

compartment.
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

Please tell or remind anyone who works on your Cadillac 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 Cadillac dealer and the
1993 Cadillac Service Manual
have information about the air bag system, including repair or disposal.

A CAUTION: I
I 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. Avoid wires wrapped with yellow
tape, or yellow connectors. They are probably part of the air bag system.
Your vehicle has a driver’s air bag and a right front passenger’s air bag.
Both air bags must be disconnected
if the ignition has to be on for
electrical work or if the steering column is to be disassembled.
Disconnect both air bags like this:
Turn off the ignition.
Remove the SIR (air bag) fuse (see “Fuses and Circuit Breakers” in

When the work
is complete, if the air bag system was disconnected, be
sure to reattach everything and replace the fuse before turning the
ignition
on. When you turn the ignition key on, be sure you see the
inflatable restraint light on the instrument panel. If you don’t see this
light flash and then go out as usual, have your air bag system repaired.

feature is in use.
When you want to open a rear door when the security lock is on:
1. Unlock the door from the inside.
2. Then open the door from the outside.
To cancel the rear door lock:
1. Unlock the door from the inside and open the door from the outside.
2. Move the lever all the way down.
- 3. Do the same for the other rear door.
The rear door locks will now work normally.
THEFT
Vehicle theft is big business, especially in some cities. Although your
Cadillac 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 walk away from 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 Cadillac 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 transmission. 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.
Lock the glove box.
Lock all the doors except the driver’s.
