CHEVROLET CORVETTE 2005 - Manual (Page 154)

If the outside temperature goes up, the displayed
temperature will not change until:
• The vehicle’s speed is above 10 mph (16 km/h)
five minutes.
• The vehicle’s speed is above 32 mph (52 km/h) for
two and a half minutes.
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 floor/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
floor/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 floor 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.
