2009 CHEVROLET CORVETTE sensor

When the vehicle is rst started, the display shows the
driver’s temperature setting, the outside temperature,
the fan speed and the air delivery, for about 10 seconds.
The outside temperature is shown in the center of the
display. The digital display will show the readings
in Fahrenheit or Celsius. See “Personal Options”
underDIC Vehicle Personalization on page 3-71for
information on changing your display.
Automatic Operation
AUTO (Automatic):Press the AUTO button to place
the entire system in the automatic mode. When
automatic operation is active, the system automatically
controls the inside temperature, the air delivery
mode, and the fan speed.
After a ten second display of the current settings,
the word AUTO, the driver’s temperature setting
and the outside temperature will be shown.The system operates to reach the set temperature as
quickly as possible. The AUTO control system works
best with the windows up and the removable roof
installed or the convertible top up.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 60°F (16°C) and 90°F (32°C). Choosing
the coldest or warmest temperature setting will
not cause the system to heat or cool any faster.
A setting of 73°F (23°C) is suggested.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system starts
out blowing air at the oor but may change modes
automatically as the vehicle warms up to maintain
the chosen temperature setting. The length of
time needed for warm up depends on the outside
temperature and the length of time that has elapsed
since the vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensor” later in
this section.

The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine.
This is normal.
?(Recirculation):Press to turn the recirculation
mode on or off. An indicator light comes on to show that
recirculation is on. This mode prevents outside air
from entering your vehicle. It can be used to prevent
outside air and odors from entering your vehicle and to
help cool the air inside your vehicle more quickly.
Recirculation mode is not available in defrost or
defog mode.
Sensors
The solar sensor on the vehicle monitors the solar heat
and uses the information to maintain the selected
temperature when operating in AUTO mode by
automatically adjusting the temperature, fan speed and
air delivery system. The system may also supply
cooler air to the side of the vehicle facing the sun.
The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located on the
top of the instrument panel near the windshield or the
system will not work properly.There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps to maintain the temperature inside the vehicle.
Any cover on the front of the vehicle could give a false
reading in the temperature.
If the outside temperature goes up, the displayed
temperature will not change until:
The vehicle’s speed is above 12 mph (19 km/h) for
ve 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.

Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the airbag
modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 1-44.
The airbag readiness light
ashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
xed immediately.{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inate in a crash, or they could even inate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come
on. SeeDIC Warnings and Messages on page 3-54

The ZR1 also has an electronic brake pad wear sensor
system. When pads are worn, the CHANGE BRAKE
PADS message displays in the Driver Information Center.
SeeDIC Warnings and Messages on page 3-54.Some driving conditions or climates can cause a brake
squeal when the brakes are rst applied or lightly applied.
This does not mean something is wrong with the brakes.
Brake linings should always be replaced as complete
axle sets.
Brake Rotor Wear
ZR1 models have ceramic brake rotors. Rotors should
be visually inspected whenever the brake pads are
replaced. Rotors also need to be weighed before brake
pads are replaced to conrm that the rotor mass is
greater than the wear-out mass printed on the rotor.
The rotor can be reused if the weight of the rotor is above
the mass limit. Rotor inspection and weighing methods
can be found in the service manual. SeeService
Publications Ordering Information on page 7-15.

To locate the nearest GM or run-at servicing facility, call
Roadside Assistance. For phone numbers and Roadside
Service details seeRoadside Assistance Program on
page 7-7.
{CAUTION:
Run-at tires are constructed differently than other
tires and could explode during improper service.
You or others could be injured or killed if you
attempt to repair, replace, dismount, or mount a
run-at tire. Let only an authorized run-at service
center repair, replace, dismount, and mount run-at
tires.
The valve stems on your run-at tires have sensors that
are part of the Tire Pressure Monitor System (TPMS).
SeeTire Pressure Monitor System on page 5-73.
These sensors contain batteries which are designed
to last for 10 years under normal driving conditions.
See your dealer/retailer if you ever need to have a wheel
replaced, or if the sensors ever need replacement.
Notice:Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in the
vehicle’s run-at tires. This damage would not be
covered by warranty. Do not use liquid sealants
in the vehicle’s run-at tires.
Ination - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-ination or over-ination is all right.
It is not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazards
