2003 Chevrolet Corvette Owner ManualM

Unless the passenger's air bag has been turned off,neverput a rear-facing child restraint in this vehicle.
Here's why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the passenger's air
bag in¯ates. This is because the back of the
rear-facing child restraint would be very close
to the in¯ating air bag. Do not use a
rear-facing child restraint in this vehicle unless
the passenger's air bag has been turned off.
If a forward-facing child restraint is suitable for
your child, always move the passenger seat as
far back as it will go.
{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 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
passenger's position (for example, don't
secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced.
See ªAir Bag Off Switchº in the Index.
1-35

Additional windshield breakage may also occur from the
passenger air bag.
·Air bags are designed to in¯ate only once. After an
air bag in¯ates, 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 bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
·Your vehicle is equipped with a diagnostic module,
which records information about the air bag
system. The module records information about the
readiness of the system, when the system
commands air bag in¯ation and driver's safety belt
usage at deployment. The module also records
speed, engine rpm, brake and throttle data.
·Let only quali®ed technicians work on your air bag
systems. Improper service can mean that an air
bag system won't work properly. See your dealer for
service.
Notice:If you damage the covering for the driver's
or the passenger's air bag, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel or both the air bag
module and the instrument panel for the
passenger's air bag. Do not open or break the air
bag coverings.
Air Bag Off Switch
Your vehicle has a switch in the glove box that you can
use to turn off the passenger's air bag.
This switch should only be turned to AIR BAG OFF if
the person in the passenger's position is a member of a
passenger risk group identi®ed by the national
government as follows:
1-44

To turn the 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 7-10.
{CAUTION:
For up to 10 seconds 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 yellow wires,
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.
1-47

Changes or modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
If you ever notice a decrease in the remote keyless
entry transmitter range, try doing one of the following:
·Check the distance. You may be too far from
your vehicle. You may need to stand closer during
rainy or snowy weather.
·Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
·Check to determine if battery replacement is
necessary. See ªBattery Replacementº under
Remote Keyless Entry System Operation on
page 2-5.
·Check to make sure that an electronic device such
as a cellular phone or lap top computer is not
causing interference.
·If you're still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System
Operation
Your vehicle has a Remote Keyless Entry (RKE) system
that allows you to lock and unlock your doors, unlock
your hatch/trunk lid, turn the panic alarm on and off and
disarm or arm your theft-deterrent system. The range
distance is as much as 100 feet (30 m) away.
Your vehicle comes
standard with two
transmitters, and up to
three can be matched to
your vehicle.
See ªMatching Transmitter(s) to Your Vehicleº later in
this section.

The key must be clean and dry before it's inserted in
the ignition or the engine may not start. If the SECURITY
light comes on, the key may be dirty or wet.
If this happens and the starter won't work, turn the
ignition off. Clean and dry the key, wait three minutes
and try again. If the starter still won't work, wait
three minutes and try the other ignition key. At this time,
you may also want to check the fuses. See
Fuses
and Circuit Breakers on page 5-86. If the starter won't
work with the other key, your vehicle needs service.
If your vehicle does start, the ®rst ignition key may be
faulty. See your dealer or a locksmith who can
service the PASS-Key
ž.If you accidentally use a key that has a damaged or
missing resistor pellet, you will see no SECURITY light.
You don't have to wait three minutes before trying
the proper key.
If the resistor pellet is damaged or missing, the starter
won't work. Use the other ignition key, and see your
dealer or a locksmith who can service the PASS-Key
žto
have a new key made.
If the SECURITY light comes on while driving, have
your vehicle serviced as soon as possible.
If you lose or damage a PASS-Key
žignition key, see
your dealer or a locksmith who can service PASS-Keyž.
In an emergency, call Chevrolet Roadside Assistance.
See
Roadside Assistance Program on page 7-6for more
information.
2-18

Ignition Positions
With the key in the ignition
switch, you can turn it to
four different positions.
OFF:This is the only position from which you can
remove the key.
If you have an automatic transmission, the ignition
switch can't be turned to OFF unless the shift lever is in
PARK (P).
ACC (ACCESSORY):This is the position in which you
can operate your electrical accessories.{CAUTION:
If you have a manual transmission removing
the key from the ignition switch will lock the
steering column and result in a loss of ability to
steer the vehicle. This could cause a collision. If
you need to turn the engine off while the vehicle
is moving, turn the key to ACC.
Notice:If your key seems stuck in OFF and you
can't turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of this works, then
your vehicle needs service.
ON:This is the position to which the switch returns
after you start the engine and release the key. The
switch stays in ON while the engine is running. But even
when the engine is not running, you can use ON to
operate your electrical accessories and to display some
instrument panel cluster messages and telltales.
START:This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON for normal driving.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows a deployed air bag symbol.
The system checks the air bag's electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the air bag
modules, the wiring and the diagnostic module. For
more information on the air bag system, see
Air
Bag System on page 1-39.
This light will come on
when you start your
vehicle, and it will ¯ash for
a few seconds. Then
the light should go out.
This means the system
is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not in¯ate in a crash, or they
could even in¯ate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.
The air bag readiness light should ¯ash for a few
seconds when you turn the ignition key to ON. If the
light doesn't come on then, have it ®xed so it will
be ready to warn you if there is a problem.
