How the Air Bag System Works
Q: Where is the air bag?
A The driver's air bag is in the middle
of the steering wheel.
Q: When is an, air bag expected to
inflate?
A: 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 irito a
wall
that does not move or deform, the
tbeshold level for most GM vehicles
is between 9 and 14 mph (14 and
23 ldh). However, thi,s velocity
threshold depends on
the vehicle
design
and may be several miles-per-
hour faster
or slower. In addition,
28
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 impacls where the
inflation would provide no occupant
protection benefit.
In any
particular ;crash, the
determination
of whetherthe ail bag
should have inflated cannot be based
solely on the level of dgrnage 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.
Q: What makes -an air bag inflate?
A: In a.frontal impact of sufficient
severity, sensors strategically located
an the vehicle. detect th& the vehicle
is. suddenly stopping .as a result of a
crash. These sensors complete an
electrical circuit, triggelling-
a
chemical reaction of the sodium-
az-ide sealed in the .inflator. The
reaction produces nitrogen
gas;
which inflates the cloth bag. The
inflator, cloth bag,
and related
hadwareare all
part of the air bag
inflator module packed inside the
steering wheel.

Q: How does an air bag restrain?
A: In moderate to severe frontal or
near=frontal collisions, even belted
occupants
can contact the steering
wheel. 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 hoderate to
severe frontal
and near-frontal
collisions.
Q: What wiu you see after an air bag
Mation?
A: Mer the air bag has inflated, it will
then quickly
deffate. This occurs so
quickly that some people may not
even realize that the air bag Sated.
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 bag. 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 ventdinto
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 we also
vented into the passenger
compartment.

How fhe Air Bag System Works
(CONT.)
CAUTION
Don’t attach .anything’to

the:air bag.module and possibly
other
parts. The service manual
has. information about the need
to
replace other parts.

Servicing Your Corvette with the
Air Bag System
Please tell or remind anyone who works
on your Corvette that
it fias 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
Chevrolet dealer and the 1993 Corvette
Service Manual have information about
the air bag system, including repair or
disposal.
When electrical work is done under the
hood or inside your vehicle, the ignition
should be in
Lock, if possible.
Avoid yellow wires, wires wrapped with
yellow tape, or yellow connectors. They
are probably part
of the air bag system.
But if the ignition has to be on for
electrical work, or if the steering column
is to be disassembIed, the air bag system
must be disconnected.

Downloaded from www.Manualslib.com manuals search engine To do this:
Turn off the ignition,.
Remove the SIR (air bag) fuse (.see
the
Index under Fuses G Circuit
Breukers) .
Disconnect the yellow connector at-
the base
of the steering column..
Whe~ 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 Driver Information Center. If you
don’t see this light flash and thea go out
,as usual, have y0.u~ air bag system
repaired,
Safety Belt Use During Pregnancy
Safety -belts work for-everyone,
including pregnant women. We
all
-occupants, they are more likely to be
seriously injured -if? they don’t wear
safety belts I
,A pregrgmt woman should wear a lap-
shoulder belt, .and the lap p.ortiun
-should be.wolin as low as possible
,throughout the pregnancy.
The bestway t~ protect the fetus is to
protect the mother; men a safety belt is
worn properly, it’s. more l.ikely that the
fetus
won’t be hurt in.3 crash. For-
-pregnant women, .as for anyone, the key
.to making safety be1tseffective.is
