CHEVROLET CORVETTE 2009 6.G Owners Manual

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is
in the passenger compartment. SeeIgnition
Positions on page 2-22. Press the bottom of the
Acc. button on the instrument panel and hold
the button down for ve seconds. The instrument
panel, including the check engine light, will light up
and the ignition will be on, but the engine will not
start — press the bottom of the Acc. button only
briey, less than ve seconds, the accessory power
mode will be turned on, but not the ignition.
After the bulb check, press and release the Acc.
button again to turn the ignition off and avoid
draining the vehicle’s battery.
The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if the battery has recently
been replaced or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This can take several days of routine
driving. If this has been done and the vehicle still
does not pass the inspection for lack of OBD II
system readiness, your dealer/retailer can prepare
the vehicle for inspection.

Engine Oil Pressure Gage
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
The engine oil pressure gage shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi (140 to 550 kPa).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still
be considered normal. It may vary with engine speed,
outside temperature and oil viscosity, but readings
above the shaded area show the normal operating
range. Readings in the shaded area tell you that the
engine is low on oil, or that you might have some other
oil problem. SeeEngine Oil on page 5-20. United States

Fuel Gage
The fuel gage shows
how much fuel the vehicle
has left while the engine
is on.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
When the needle approaches the low fuel symbol, a
chime sounds and LOW FUEL appears on the Driver
Information Center (DIC) display. There is still a little fuel
left, but the vehicle’s fuel tank should be lled soon.
Press the RESET button to acknowledge a DIC
message(s). Pressing the RESET button also turns off a
DIC message but the LOW FUEL message comes on
again in 10 minutes if fuel is not added to the vehicle.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 service station, the gas pump shuts off
before the gage reads the full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated half full, but it took a little more or
less than half of the tank’s capacity to ll the tank.
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 Operation and Displays on page 3-49for more
information.

Boost Gage (ZR1 Only)
For vehicles that have this gage, it is located near the
driver side of the instrument panel cluster.
This gage indicates vacuum during light to moderate
throttle and boost under heavier throttle.
It displays the air pressure level in the intake manifold
before it enters the engine’s combustion chamber.
The gage is automatically centered at zero every time
the engine is started. Actual vacuum or boost is
displayed from this zero point. Changes in ambient
pressure, such as driving in mountains and changing
weather, will slightly change the zero reading.
Driver Information Center (DIC)
The Driver Information Center (DIC) display is located
on the instrument panel cluster and shows driver
personalization features and warning/status messages.
The DIC buttons are located on the instrument panel,
to the right of the cluster.
The DIC comes on when the ignition is turned on.
After displaying CORVETTE BY CHEVROLET, the DIC
shows the information that was last displayed before
the engine was turned off.
If a problem is detected, a warning message appears
on the DIC display. SeeDIC Warnings and Messages
on page 3-54for more information.
DIC Operation and Displays
Depending on the features on the vehicle, the drive
gear may display on the DIC. See “Manual Paddle Shift”
