Downloaded from www.Manualslib.com manuals search engine This vehicle has AIR BAGS for front occupants.
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
while you are driving, or doesn't come on when you first start your vehicle, see your Dealer for service.

in position for air bag inflation in a crash.

lir Bag System
'his section explains the air bag system.
our Corvette has an air bag for the
river and the passenger. Here are the
most important things to
know:

that the air bag inflated. Some
components of the air bag module
in the
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
not
impede the driver’s vision or ability to
steer the vehicle, nor will it hinder
‘the
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,
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
... 26
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
for service.
NOTICE:
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
on the steering
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
harmful?
The particles emitted during air bag
inflation are not harmful to most people.
Some people with respiratory ailments may experience difficulty breathing
if
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
Corvette
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
and
the air bag system. The air bag
system does not need regular
maintenance.

Transmitter Range
The transmitter range depends on your
vehicle and where you are standing. The
coupe
(A) has an antenna in the driver’s
door and one in the rear area. The
convertible
(B) has one antenna in each
door. The antennas do not require any
maintenance.
Range also depends on how you hold
the transmitter. For best performance,
when you come near your vehicle, hold
the transmitter straight up and down,
so
the keys hang down.
If the range seems to be decreasing,
check the battery
in the transmitter.
Range will decrease if the battery is
low. It will also decrease if more than
one transmitter is in the area. Don’t put
the transmitter in a metal container
because the transmitter won’t work.
Matching Transmitter(s) to Your
Vehicle
Each key chain transmitter is coded to
prevent another transmitter from
unlocking your vehicle. If a transmitter
is lost or stolen, a replacement can be
?urchased through your dealer.
Remember to bring any remaining
:ransmitters with you when you go to your dealer. When the dealer matches
the replacement transmitter
to your
vehicle, the remaining transmitters must
also be matched. Once the new
transmitter is coded, the lost transmitter
will not unlock your vehicle.
You can match a transmitter to as many
different vehicles as you own, provided
they are equipped with exactly the same
model -system. (General Motors offers
several different models of these
systems on their vehicles.) Each vehicle
can have only three transmitters
matched to it.
To match transmitters to your
vehicle:
1. Move all transmitters out of range.
2. Turn the ignition on.
3. Push “TRIP ODO’ on the Driver
Information Center twice.
4. Within five seconds press and hold
“FUEL INFO’ until the “PASSIVE
KEYLESS ENTRY” light comes on.
5. Turn the ignition off, but leave the
key in the ignition. The “PASSIVE
KEYLESS ENTRY” light should
begin to flash to show the system is
in programming mode.

For LTPWS to work properly, you must
drive your Corvette faster than
25 mph
(40 km/h) and for more than
2 miles
(4 km). The system will not warn you
before
you begin to drive that a tire is flat.
When the “LOW/FLAT TIRE’ light
comes on, check
the tire pressure in all
four road tires as soon as you can. Adjust
the tire pressure as needed to those shown
on the Tire-Loading Information label on
the driver’s door. If the light stays on after
the tire pressure is adjusted, see your
dealer.
NOTICE:
Driving with a flat tire may damage
the tire,
the wheel or the tire pressure
sensor installed inside the tire on the
wheel rim. Using tire sealants may
also damage
the sensor.
If you have EMTs, see “Extended
Mobility Tires”
in the Index. The
LTPWS sensor is directly opposite
the valve stem on the tire. Take care when
servicing or having your tires serviced.
The sensors may not work properly if
damaged. To prevent damage to the
sensors, see the 1994 Corvette Service
Manual for correct tire mounting and
dismounting procedures.
The “LOWRLAT TIRE” light may come
on if your vehicle is close to another
vehicle that has LTPWS and has a tire
with low pressure.
LTPWS can
warn you about a low tire,
but it does not replace normal tire
maintenance. See “Tires” in the Index.

Automatic Transmission Fluid
When to Check and Change
4 good time to check your automatic
:ransmission fluid level is when the
mgine oil is changed. Refer to the
Maintenance Schedule to determine when
co change your fluid. See “Scheduled
Maintenance Services” in the Index.
How to Check
Because this operation can be a little
iifficult, you may choose to have this
done at a Chevrolet dealership Service
Department.
[f you do it yourself, be sure to follow all
the instructions here, or you could get a
false reading on the dipstick.
NOTICE:
Too much or too little fluid can dam-
age your transmission.
Too much can
mean that some of the fluid could
come out and fall
on hot engine parts
or exhaust system, starting a fire. Be
sure to get an accurate reading if you
check your transmission fluid. Wait
at least 30 minutes before checking
the transmission fluid level if you have
been driving:
0 When outside temperatures are above
0 At high speed for quite a while.
0 In heavy traffic - especially in hot
To get the right reading, the fluid should
be at normal operating temperature, which is
180°F to 200°F (82°C to 93°C).
To check transmission fluid hot: Get
the vehicle warmed up by driving
about
15 miles (24 km) when outside
temperatures are above
50°F (10°C). If
it’s colder than
50°F (10°C)’ drive the
vehicle in
“D’ (Third Gear) until the
engine temperature gage moves and then
remains steady for ten minutes. Then follow the hot check procedures.
To check transmission fluid cold: A cold
check is made after the vehicle has been sitting for eight hours or more with the
engine
off and is used only as a reference.
Let the engine run at idle for five minutes
if outside temperatures are 50” F ( 1 OOC)
or more. If it’s colder than 50°F ( 10°C)’
you may have to idle the engine longer.
Should the fluid level be low during a
