2003 CHEVROLET EXPRESS CARGO VAN ignition

Medical Condition.A passenger has a
medical condition which, according to his or
her physician:
·causes the passenger air bag to pose a special risk
for the passenger; and
·makes the potential harm from the passenger air
bag in a crash greater than the potential harm
from turning off the air bag and allowing the
passenger, even if belted, to hit the dashboard or
windshield in a crash.
{CAUTION:
If the right front passenger's air bag is turned
off for a person who isn't in a risk group
identi®ed by the national government, that
person won't have the extra protection of an
air bag. In a crash, the air bag wouldn't be able
to in¯ate and help protect the person sitting
there. Don't turn off the passenger's air bag
unless the person sitting there is in a risk
group. See ªAir Bag Off Switchº in the Index.To turn off the right front passenger's air bag, insert
your ignition key into the switch, push in, and move the
switch to AIR BAG OFF.
1-71

The AIR BAG OFF light will come on to let you know
that the right front passenger's air bag is off. The
right front passenger's air bag will remain off until you
turn it back on again, and the AIR BAG OFF light
will stay on to remind you that the air bag is off.
{CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bag, it means
that something may be wrong with the air bag
system. The right front passenger's air bag
could in¯ate even though the switch is off.
If this ever happens, don't let anyone whom
the national government has identi®ed as a
member of a passenger air bag risk group
sit in the right front passenger's position
(for example, don't secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced.To turn the right front passenger's air bag on again,
insert your ignition key into the switch, push in,
and move the switch to the on position.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't want the system to
in¯ate while someone is working on your vehicle. Your
dealer and the service manual have information
about servicing your vehicle and the air bag system. To
purchase a service manual, see
Service Publications
Ordering Information on page 7-9.
{CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an
air bag can still in¯ate during improper
service. You can be injured if you are close to
an air bag when it in¯ates. Avoid wires
wrapped with yellow tape or yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is quali®ed to do so.
The air bag system does not need regular maintenance.

Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer.Remember to bring any remaining transmitters with
you when you go to your dealer. When the dealer
matches the replacement transmitter to your vehicle,
any remaining transmitters must also be matched. Once
your dealer has coded the new transmitter, the lost
transmitter will not unlock your vehicle. Each vehicle can
have a maximum of four transmitters matched to it.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver. The
receiver will not respond to a signal that has been
sent previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the LOCK and UNLOCK
buttons on the transmitter at the same time for seven
seconds. The door locks should cycle to con®rm
synchronization. If the locks do not cycle, see your
dealer for service.
