2007 CHEVROLET CORVETTE engine

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.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
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 90. 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 — if you pressthe 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,
be sure to press and release the Acc. button again
to turn the ignition off and avoid draining the
vehicle’s battery.
Your vehicle will not pass this inspection if the
OBD (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 you have recently replaced
the battery or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This may take several days of routine
driving. If you have done this and your vehicle
still does not pass the inspection for lack of
OBD system readiness, your dealer can prepare
the vehicle for inspection.

Engine Oil Pressure GageThe 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 333.
The engine oil pressure can also be displayed
using the GAGES button on the Driver Information
Center (DIC). SeeDriver Information Center (DIC)
on page 207.

{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become
so hot that it catches re. You or others
could be burned. Check your oil as
soon as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
Security Light
For information
regarding this light,
seeTheft-Deterrent
Systems on page 87.
Fog Lamp Light
The fog lamp light
will come on when
the fog lamps are
in use.
The light will go out when the fog lamps are
turned off. SeeFog Lamps on page 171for
more information.
205

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.
