2009 CHEVROLET CORVETTE engine

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.

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.
The rear window defogger turns off about 10 minutes
after the button is pressed when traveling less than
30 mph (48 km/h). If turned on again, the defogger only
runs for about ve minutes before turning off. The
defogger can also be turned off by turning off the engine.
The vehicle has heated outside rearview mirrors.
The mirrors will heat to help clear fog or frost from the
surface of the mirrors when the rear window defogger
button is pressed.
For vehicles with a power convertible top, the rear
window defogger and heated mirrors are automatically
disabled when the power convertible top is moving
or down.Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by the vehicle warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.Outlet Adjustment
Use the tab located on the air outlets to change the
direction of the airow.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.

Passenger Compartment Air Filter
The passenger compartment air lter removes certain
particles from the air including pollen and dust particles.
Reductions in airow, which may occur more often in
dusty areas, indicate that the lter may need to be
replaced. SeeScheduled Maintenance on page 6-4
for information on how often to replace the lter.
Notice:Driving without a passenger compartment
air lter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the
old lter with a new one.
The passenger compartment air lter is located on the
passenger side of the engine compartment near the
battery. SeeEngine Compartment Overview on
page 5-14.To check or replace the air lter:
1. Remove the cover retainer clips (A) from the
passenger compartment air lter cover.
2. Remove the cover.

3. Remove the lter and install the new air lter.
4. Replace the lter cover.
5. Attach the retainer clips.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is started
to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.

Speedometer and Odometer
The speedometer shows the speed in either miles per
hour (mph) or kilometers per hour (km/h). For more
information see “Personal Options” underDIC Vehicle
Personalization on page 3-71.
To read the odometer with the ignition off, turn on the
parking lamps.
If the vehicle needs a new odometer installed, the
mileage total of the new odometer will be set to the
original miles (kilometers) of the old odometer. See your
dealer/retailer if the odometer must be replaced in the
vehicle.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Notice:Fuel shuts off at about 6500 rpm for the
base model, 7000 rpm for the Z06 model, and
6600 rpm for the ZR1 model. If the vehicle continues
to be driven at the fuel shut off rpm, the engine
could be damaged. Be sure to operate the vehicle
below the fuel shut off rpm or reduce the vehicle’s
rpm quickly when the fuel shuts off.

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
for more information.

If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be a
problem with the lights or the passenger sensing
system. See your dealer/retailer for service.
{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 3-35
for more information, including important safety
information.
Voltmeter Gage
The voltmeter shows the
voltage output of the
battery. It shows the
voltage output of the
charging system while the
engine is running.
The reading changes as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, the instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) reads BATTERY VOLTAGE
LOW when the vehicle is at 10 volts or below. Have it
checked right away. Driving with the voltmeter reading at
10 volts or below could drain the battery and disable
the vehicle.Base and Z06
