The Dual Zone Electronic Climate Control System
uses several sensors to control operation and
display information.
Solar Load Sensor
This sensor is located on the top right side of the
defroster grille. The defroster grille is on the top of the
instrument panel.
The sensor monitors the sun’s solar radiation and uses
this information as
part of the automatic climate control
system when operating in the
AUTO mode.
Be careful not to put anything over the sensor. It cannot
compensate for changes in the amount of heat the
vehicle is absorbing from the sun when covered.
Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor
is used for the outside air temperature readings
shown on the digital display for the automatic climate
control system. If
the outside temperature goes up, the displayed
temperature will not change until:
The vehicle’s speed is above 20 mph (32 km/h) for
one and a half minutes.
0 The vehicle’s speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature display
is updated immediately.
If your vehicle has been turned off for more than
three hours, the current outside temperature will be
shown when you start the vehicle. If it has been turned
off for less than three hours, the temperature will be
recalled from the previous vehicle operation.
Inside Temperature Sensor
This sensor is located just left of the ignition switch.
The automatic climate control system uses this sensor
to receive information
so if you block or cover it, the
system will not function properly.

Downloaded from www.Manualslib.com manuals search engine When you enter a vehicle in cold weather, turn the
blower fan to the highest speed for a few moments
before driving
off. This helps clear the intake outlets
of snow and moisture, and reduces the chance of
fogging the inside of the windows.
Keep the area around the base of the center
instrument panel console and air path under the seats
clear of objects. This helps air circulate throughout
your vehicle.

Downloaded from www.Manualslib.com manuals search engine vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. If
this occurs, return
to your authorized Corvette dealer for diagnosis to
determine the cause of failure. In the event it is
determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not
his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on. If
this occurs, return to your authorized
Corvette dealer for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming
in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol,
and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask
an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.

Downloaded from www.Manualslib.com manuals search engine Extended Mobility Tires
Your vehicle, when new, had Goodyear Extended
Mobility Tires (EMT). There’s no spare tire, no tire
changing equipment and no place to store a tire in the
vehicle. Extended Mobility Tires perform
so well
without any air that a Tire Pressure Monitor (TPM) is
used to alert you if a tire has lost pressure.
The Tire Pressure Monitor (TPM) 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 and
with Industry and Science Canada.
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 interference, and
(2)
this device must accept any interference received,
including interference that may cause undesired operation.
This device complies with RSS-210 of Industry and
Science Canada. Operation is subject to the following
two conditions: (1) this device may not cause
interference, and (2) this device must accept any
interference received, including interference that may
cause undesired operation of the device. Changes or modifications
to this system
by other than an
authorized service facility could void authorization to
use this equipment.
If a tire’s inflation pressure is between
5 psi (35 kPa)
and 25 psi (170 kPa), you will see a message on the
Driver Information Center. This message will show
which tire is underinflated and two chimes will sound.
An example would
be LOW TIRE PRESSURE-LR.
This would mean that the inflation pressure in your left
rear tire is between 5 psi (35 Pa) and 25 psi (170 Pa).
If the inflation pressure in the tire drops below
5 psi
(35 Ea), the message would read FLAT TIRE-LR and
four chimes will sound.
See “Driver Information
Center” in the Index.
The TPM will also alert you if a tire’s pressure is higher
than
42 psi (290 Wa). The message will show which tire
is overinflated and two chimes will sound. An example
would be HIGH PRESSURE-LR. This would mean that
the inflation pressure in your left rear tire is higher than
42 psi (290 kPa). See “Driver Information Center” in
the Index.
If a tire pressure message appears on the Driver
Information Center, stop as soon as you can. Have
the
tire pressures checked and set to those shown on your
Tire Loading Information label. See “Inflation
-- Tire
Pressure” in the Index.

Downloaded from www.Manualslib.com manuals search engine Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause .annoying reflections in the windshield
and even make it difficult to see through the windshield
under certain conditions.
Cleaning Interior Plastic Components
Use only a mild soap and water solution on a soft
cloth
or sponge. Commercial cleaners may affect the
surface finish.
Cleaning Soft-Touch Paint Surfaces
Use only mild soap and water to clean the Soft-Touch
paint surfaces in your Corvette.
Cleaning the Security Shade and
Convenience Net
Wash with warm water and mild detergent, rinse
with cold water and tumble dry on low. Do not use
chlorine bleach.
Care of Safety Belts
Keep belts clean and dry.
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they might not be able
to provide adequate protection.
Clean safety belts only with mild soap and
lukewarm water.
Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner (GM
Part No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films on
interior glass.
Don’t use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped
off later. If
abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.
