2007 CHEVROLET CORVETTE air condition

These delays prevent false readings. If the
temperature goes down, the 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.
There is also an inside temperature sensor
located to the 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.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity and moisture condensing on the cool
window glass. This can be minimized if the climate
control system is used properly. There are two
modes to clear fog or frost from your windshield.
Use the oor/defog mode to clear the windows of
fog or moisture and warm the passengers. Use
defrost to remove fog or frost from the windshield
more quickly. To prevent fogging on the inside of
the windows in modes other than oor/defog and
defrost, make sure the air conditioning compressor
is on and recirculation mode is off.
Press the mode button until the defog mode
appears on the display.
-(Floor/Defog):This mode directs the air
equally between the windshield and the oor
outlets with a small amount to the side window
outlets. When you select this mode, the system
turns off recirculation and runs the air-conditioning
compressor unless the outside temperature is
at or below freezing. The recirculation mode
cannot be selected while in the defog mode.
1(Defrost):Pressing this button directs most
of the air to the windshield, with a small amount
directed to the side window outlets. The light on the
button will come on and the digital display will show
the defrost mode symbol and fan speed when the
front defrost mode is being used. In this mode, the
system will automatically turn off the recirculation
and run the air-conditioning compressor, unless
the outside temperature is at or below freezing.
Recirculation cannot be selected while in the
defrost mode. Pressing this button again will return
the system to the last operating mode.
For severe ice conditions, turn the driver’s
temperature knob to 90°F (32°C) while in
defrost mode.
Do not drive the vehicle until all the windows
are clear.

This light should come on briey, as a check to
show you it is working, as you start the engine.
If the light does not come on, have it repaired.
This light will also come on during a malfunction
in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis
and service may be required.
Light On Steady— An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service may
be required.
If the Light Is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to
do so, stop the vehicle. Find a safe place to
park your vehicle. Turn the engine off, wait at
least 10 seconds and restart the engine. If the
light remains on steady, see “If the Light Is
On Steady” following. If the light is still ashing,
follow the previous steps, and see your dealer
for service as soon as possible.

If this occurs, return to your authorized GM dealer
for diagnosis. If it is determined that the condition is
caused by the type of fuel used, repairs may not be
covered by your warranty.
Additives
To provide cleaner air, all gasolines in the
United States are now required to contain additives
that will help prevent engine and fuel system
deposits from forming, allowing your emission
control system to work properly. In most cases,
you should not have to add anything to your
fuel. However, some gasolines contain only the
minimum amount of additive required to meet U.S.
Environmental Protection Agency regulations.
To help keep fuel injectors and intake valves clean,
or if your vehicle experiences problems due to
dirty injectors or valves, look for gasoline that is
advertised as TOP TIER Detergent Gasoline.
Also, your dealer has additives that will help
correct and prevent most deposit-related problems.
Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gasolines
may be available in your area. General Motors
recommends that you use these gasolines if they
comply with the specications described earlier.However, E85 (85% ethanol) and other fuels
containing more than 10% ethanol must no
be used in vehicles that were not designed for
those fuels.
Notice:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in the fuel system and also damage
plastic and rubber parts. That damage would
not be covered under your warranty.
Some gasolines that are not reformulated for
low emissions may contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
General Motors recommends against the use of
such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of
the emission control system may be affected.
The malfunction indicator lamp may turn on.
If this occurs, return to your dealer for service.
