2007 CHEVROLET CORVETTE fuel cap

Pressing the arrows will delete AUTO from the
digital display. The fan graphics with the fan speed
bars will be shown. To increase the fan speed
so that more air ows into the vehicle, press the
up arrow on the fan switch. To decrease the
fan speed and airow, press the down arrow.
The AUTO button must be pressed to return to the
automatic fan control.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 186andScheduled Maintenance on
page 433.
?(Recirculation):Press this button to turn the
recirculation mode on or off. When the climate
control system is in recirculation mode an indicator
light will come 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.
^(Air Conditioning Off):Press this button
to turn the air conditioning compressor off.
Press AUTO to return to automatic operation.
When in AUTO, the air conditioning compressor
will come on automatically, as needed.
Air conditioning does not operate at temperatures
below about 35°F to 40°F (2°C to 4°C).
In temperatures above 40°F (4°C), the air
conditioning cannot be turned off in defrost and
defog, as it helps to remove moisture from the
vehicle. It also helps to keep the windows clear.
You may notice a slight change in engine
performance when the air-conditioning compressor
shuts off and turns on again. This is normal.
The system is designed to make adjustments to
help with fuel economy while still maintaining
the selected temperature.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.

If the Light Is On Steady
You also may be able to correct the emission
system malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 324.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed.
A loose or missing fuel cap will allow fuel to
evaporate into the atmosphere. A few driving
trips with the cap properly installed should turn
the light off.
Did you just drive through a deep puddle of
water?
If so, your vehicle’s electrical system may be wet.
The condition will usually be corrected when
the electrical system dries out. A few driving trips
should turn the light off.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 321. Poor fuel
quality will cause the engine not to run as efficiently
as designed. You may notice this as stalling after
start-up, stalling when you put the vehicle into gear,
misring, hesitation on acceleration, or stumbling
on acceleration. (These conditions may go away
once the engine is warmed up.) This will be
detected by the system and cause the light to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.

Here are ve things that some owners ask about.
All these things are normal and do not indicate
that anything is wrong with the fuel gage.
At the gas station, the gas pump shuts off
before the gage reads the full symbol.
It takes more (or less) fuel to ll up than the
gage reads. For example, the gage reads
half full, but it took more (or less) than half
of the tank’s capacity to t it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate the tank is empty
when the ignition is turned off.
The gage reading may change slightly within
the rst several minutes after starting the
vehicle.
SeeDIC Controls and Displays on page 208for
more information.
Driver Information Center (DIC)
The Driver Information Center (DIC) gives you
the status of many of your vehicle’s systems.
It is also used to display driver personalization
features and warning/status messages. The
DIC display is located on the instrument panel
cluster below the speedometer and tachometer,
directly above the steering column. The DIC
buttons are located on the instrument panel,
to the right of the instrument panel cluster.
The DIC comes on when the ignition is turned on.
After displaying CORVETTE BY CHEVROLET,
the DIC will display the current driver and
the information that was last displayed before
the engine was turned off.

CHANGE ENGINE OIL
This message displays when the life of the engine
oil has expired. SeeScheduled Maintenance on
page 433. After an oil change, the engine oil
life system must be reset. See “Engine Oil Life”
underDIC Controls and Displays on page 208.
Also, seeEngine Oil on page 333andEngine Oil
Life System on page 340for more information.
CHECK BRAKE FLUID
This message displays, a chime sounds, and the
brake system warning light on the instrument
panel cluster turns on if the ignition is on to inform
the driver that the brake uid level is low. See
Brake System Warning Light on page 196. Have
the brake system serviced by your dealer as
soon as possible. SeeBrakes on page 361.
CHECK COOLANT LEVEL
This message displays when the engine coolant
level is low. Have the cooling system serviced
by your dealer as soon as possible. SeeEngine
Coolant on page 347.
CHECK GAS CAP
This message displays if the fuel cap has not
been fully tightened. Check the fuel cap to make
sure that it is on properly. Once tightened, it takes
at least one overnight park to reset or clear this
message. If both the CHECK GAS CAP message
and the malfunction indicator lamp in the
instrument panel cluster are on, you may need to
see your dealer for service. SeeMalfunction
Indicator Lamp on page 200for more information.
CHECK OIL LEVEL
This message displays and two chimes sound if
the oil level in the vehicle is low. Once the vehicle
senses a change in the engine oil level, the
light remains off.
If this message appears after starting the engine,
the engine oil level may be too low. You may
need to add oil. SeeEngine Overheating on
page 350.
To acknowledge the message, press the RESET
button. The message reappears every 10 minutes
until this condition changes.

The tethered fuel cap is located behind a hinged
fuel door on the driver’s side of the vehicle.The fuel door release
button is located on
the instrument panel
to the left of the
steering wheel.
Push the button to
release the fuel door.
There is also a manual
fuel door release tab.
It is located against
the upper trim in
the rear compartment
on the driver’s side
of the vehicle. Pull
the tab to release
the fuel door.
To remove the fuel cap, turn it slowly
counterclockwise. The fuel cap has a spring
in it; if the cap is released too soon, it will
spring back to the right.
325

While refueling, let the cap hang by the tether
below the fuel ll opening.
{CAUTION:
Fuel can spray out on you if you open the
fuel cap too quickly. If you spill fuel and
then something ignites it, you could be
badly burned. This spray can happen if
your tank is nearly full, and is more likely
in hot weather. Open the fuel cap slowly
and wait for any hiss noise to stop.
Then unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon as
possible. SeeWashing Your Vehicle on page 411.
When replacing the fuel cap, turn it clockwise
until it clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the fuel caphas been left off or improperly installed. This would
allow fuel to evaporate into the atmosphere. See
Malfunction Indicator Lamp on page 200.
The CHECK GAS CAP message will be displayed
on the Driver Information Center (DIC) if the fuel
cap is not properly installed. SeeDIC Warnings and
Messages on page 214for more information.
{CAUTION:
If a re starts while you are refueling,
do not remove the nozzle. Shut off the
ow of fuel by shutting off the pump
or by notifying the station attendant.
Leave the area immediately.
Notice:If you need a new fuel cap, be sure
to get the right type. Your dealer/retailer can
get one for you. If you get the wrong type,
it may not t properly. This may cause your
malfunction indicator lamp to light and may
damage your fuel tank and emissions system.
SeeMalfunction Indicator Lamp on page 200.
