2007 CHEVROLET CORVETTE fuel

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.

Instrument Panel Cluster
Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance
how the vehicle is running. You will know how fast you are going, about how much fuel you have left and
many other things you will need to know to drive safely and economically. The instrument panel cluster
indicator warning lights, gages and DIC messages are explained on the following pages.

Speedometer and Odometer
Your speedometer lets you see your speed in
either miles per hour (mph) or kilometers per
hour (km/h). For more information see “Personal
Options” underDIC Vehicle Personalization
on page 234.
To read the odometer with the ignition off, turn
on the parking lamps.
You may wonder what happens if your 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 if the odometer must be replaced in
your vehicle.
Tachometer
The tachometer displays the engine speed in
thousands of revolutions per minute (rpm).
Notice:Fuel will shut off at about 6600 rpm
for the base model and 7100 rpm for the
Z06 model. If you continue to drive your vehicle
at the fuel shut off rpm, you could damage
your engine. Be sure to operate your vehicle
below the fuel shut off rpm or reduce your
rpm quickly when the fuel shuts off.
Safety Belt Reminder Light
When the ignition is turned on, a chime will come
on for several seconds to remind people to
fasten their safety belts, unless the driver’s safety
belt is already buckled.
The safety belt light will
also come on and stay
on for several seconds,
then it will ash for
several more.
This chime and light will be repeated if the driver
remains unbuckled and the vehicle is in motion.
If the driver’s belt is already buckled, neither
the chime nor the light will come on.

One-to-Four Shift Light
(Manual Transmission)
When this light comes
on, you can only shift
from FIRST (1) to
FOURTH (4) instead of
FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to
turn off this feature. This helps you get the
best possible fuel economy.After shifting to FOURTH (4), you may downshift
to a lower gear if you prefer.
Notice:Forcing the shift lever into any gear
except FOURTH (4) when the 1 TO 4 SHIFT light
comes on may damage the transmission.
Shift only from FIRST (1) to FOURTH (4) when
the light comes on.
This light will come on when:
The engine coolant temperature is higher than
169°F (76°C),
the vehicle is going 15 to 19 mph
(24 to 31 km/h) and
the vehicle 21 percent throttle or less.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation
of the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The check engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.Notice:If you keep driving your vehicle with
this light on, after awhile, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead
to costly repairs that might not be covered by
your warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and can cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This could also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 319.

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.

Lights On Reminder
This light comes on
whenever the parking
lamps are on.
SeeHeadlamps on Reminder on page 169for
more information.
Highbeam On Light
This light comes on
when the high-beam
headlamps are in use.
SeeHeadlamp High/Low-Beam Changer on
page 162for more information.
Fuel Gage
Your fuel gage tells you
about how much fuel
you have left when
the engine is on.
When the needle approaches the low fuel symbol,
a chime will sound and LOW FUEL will appear
on the Driver Information Center (DIC) display.
At this time, you still have a little fuel left, but you
should get more soon.
Press the RESET button to acknowledge a DIC
message(s). Pressing the RESET button will
also turn off a DIC message but the LOW FUEL
message will come on again in 10 minutes if
you have not added fuel to the vehicle.
206

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.
