A CAUTION: YOU NEED YOUR SAFETY BELT, EVEN WITH AN AIR BAG. AND HERE'S WHY:
Air bags are not designed to inflate in rollovers or in rear, side or low-speed frontal crashes.
Air bags inflate with great force, faster than the blink of an eye. If you're too close to an inflating air bag, it could seriously
An inflating air bag can seriously injure small children. Follow the instructions on the passenger safety belt Caution label.
REGULAR MAINTENANCE OF THE AIR BAG SYSTEM IS NOT REQUIRED. If the air bag readiness light comes on

that the air bag inflated. Some
components of the air bag module
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
impede the driver’s vision or ability to
steer the vehicle, nor will it hinder
occupants from exiting the vehicle.
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,
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
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

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.
Is the smoke from an air bag inflation
The particles emitted during air bag
inflation are not harmful to most people.
Some people with respiratory ailments may experience difficulty breathing
they stay in the vehicle with the windows
closed after air bag inflation.
So, if your
air bag inflates, you and any passengers
should exit the vehicle
if and when it is
safe to do
so. If you or your passengers
can’t get out of the vehicle, try to get
fresh air by opening a window, turning on
the fan, or opening a door.
Servicing Your Air Bag-Equipped
Air bags affect how your Corvette 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 Chevrolet dealer and the 1994 Corvette Service Manual have
information about servicing your vehicle
