2010 CHEVROLET CORVETTE sensor

Twilight Sentinel®
Twilight Sentinel®can turn the lamps on and off for you.
A light sensor on top of the instrument panel makes the
Twilight Sentinel
®work, so be sure it is not covered.
With Twilight Sentinel
®, the following will happen:
.When it is dark enough outside, the front turn
signal lamps (DRL) will go off, and the headlamps
and parking lamps will come on. The other lamps
that come on with headlamps will also come on.
.When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch is
in the AUTO position.
If the vehicle is started in a dark garage, the automatic
headlamp system come on immediately. Once the
vehicle leaves the garage, it takes about one minute for
the automatic headlamp system to change to DRL if it
is light outside. During that delay, the instrument panel
cluster may not be as bright as usual. Make sure the
instrument panel brightness control is in full bright
position. See Instrument Panel Brightness
on
page 4‑15.
You can idle the vehicle with the lamps off, even when
it is dark outside. After starting the vehicle, turn the exterior lamp control
band on the multifunction lever to off and then release
it. The lamps will remain off until the control band is
turned to off again.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, the lamps
will remain on until:
.The exterior lamp switch is moved from off to the
parking lamp position, or
.A delay time that you select has elapsed.
See “Personal Options” underDIC Vehicle
Personalization
on page 4‑71to select the delay time
that you want. You can also select no delay time.
If you turn off the ignition with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
The regular headlamp system should be turned on
when needed.

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 16°C (60°F) and 32°C (90°F). Choosing
the coldest or warmest temperature setting will
not cause the system to heat or cool any faster.
A setting of 23°C (73°F) 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 floor 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.Manual Operation
Driver Power/Temperature : Press the driver
temperature knob to turn the climate control system off.
This is the only setting that completely shuts off the fan.
The digital display shows only the outside temperature.
The driver and the passenger set temperature and the
air intake mode can still be adjusted when the climate
control is off.
Passenger Power/Temperature : Press the passenger
temperature knob to turn the passenger's climate
control system on or off. Turn the knob to increase or
decrease the temperature for the passenger. If the
passenger's climate control system is off, the driver's
temperature knob will control the temperature for the
entire vehicle.
x 9 w (Fan) :Press to increase or decrease the fan
speed. The fan speed setting will appear in the display.
Pressing the arrows will delete AUTO from the digital
display. The fan graphics with the fan speed bars will be
shown. The AUTO button must be pressed to return to
the automatic fan control.
If the airflow seems low when the fan speed is at the
highest setting, the passenger compartment air filter
may need to be replaced. For more information, see
Passenger Compartment Air Filter
on page 4‑28and
Scheduled Maintenance on page 7‑3.

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 19 km/h (12 mph) for
five minutes.
.The vehicle's speed is above 52 km/h (32 mph) 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.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger only works when the engine
is running.
=(Rear Window Defogger) :
Press to turn the
rear window defogger on or off. Be sure to clear
as much snow from the rear window as possible.
An indicator light comes on to show that the rear
window defogger is on.

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, see Airbag System on page 2‑44.
The airbag readiness light
flashes for a few seconds
when the engine is
started. If the light does
not come on then, have
it fixed immediately.
{WARNING:
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
inflate in a crash, or they could even inflate
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. See DIC Warnings and Messages
on
page 4‑52for more information.
