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.

in a place where the signal can’t get to
the antenna, it won’t unlock the doors.
Always remember to take your keys

does come on for a second or two, then
the PKE system is still on.
You can also check whether the system is
on or
off by closing the door and walking
away with the keys and transmitter.
If the
doors lock, the system is on.
If you are working around your vehicle
and keeping your keys with you, you
might want to turn the PKE system
off.
If you don’t, the transmitter will keep
locking and unlocking your doors.

In very cold weather, 0 “F (- 18 “C) or
colder, the engine coolant heater can help.
You’ll get easier starting and better fuel
economy during engine warm-up.
Usually, the coolant heater should be
plugged in a minimum of four hours prior
to starting your vehicle.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
3. Plug it into a normal, grounded

Daytime Running Lights (Canada)
The Canadian Federal Government has

At dusk, the exterior lights will come on
automatically and the front turn signal
lights will go out. At dawn, the exterior
lights will go out and the front turn signal
lights will come on (if the headlight
switch is
off).
Of course, you may still turn on the
headlights any time
you need to.
To idle your vehicle with the DRL off, set
the parking brake while the ignition is
in
the “Off” or “LOCK” position. Then start
the vehicle. The DRL will stay
off until
you release the parking brake.

Low Tire Pressure Warning Light
(Option)
The LTPWS has a sensor on each road
wheel that transmits to a receiver
on the
instrument panel. The system operates on
a radio frequency subject to Federal
Communications Commission (FCC)
Rules.
This device complies with Part
15 of the
FCC Rules. Operation
is subject to the
following two conditions:
1. This device may not cause harmful
2. This device must accept any
interference,
and
interference received, including
interference that may cause undesired
operation.
Changes or modifications to this system

this equipment.
LOWIFLAT
TIRE
..
The Low Tire Pressure Warning System
(LTPWS) monitors air pressure in each
road tire while you’re driving your
Corvette. The “LOW/FLAT TIRE” light
will come
on whenever tire pressure in
any road tire goes below
25 psi (175 kPa)
and it will stay
on until you turn off the
ignition. The light may come on if any
LTPWS parts aren’t working properly.

Downloaded from www.Manualslib.com manuals search engine Features and Controls
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.

quick cool-down on
very hot days. This
setting recirculates most of the air inside
your vehicle. If it is used for long
periods of time, the air may become dry.
This setting directs air through the upper
air vents. It will not work when outside
temperatures are below
40°F (5 “C).

the system will lower the inside
temperature up to
5°F (3°C) below
the setting on the display.
Outside Temperature: This sensor is

what you usually see on the display.
If the outside temperature goes up,
the displayed temperature will not
change until:
Vehicle speed is above 25 mph
(40 kmh) for at least 3 minutes,
or
Vehicle speed is above 45 mph
(72
