(CONT.)

your:. air
bag system. .If you don’t get them,
the air bag system won’t be there

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.
