2010 CHEVROLET CORVETTE Owners Manual

When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about a
minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. See Tire Pressure Monitor Operation
on
page 6‑74for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It makes sure that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
This comes on briefly
while starting the engine.
If it does not come on,
have the vehicle serviced
by your dealer/retailer. If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light can
prevent more serious damage to the vehicle. This
system assists the service technician in correctly
diagnosing any malfunction.
Notice:
If the vehicle is continually driven with this
light on, after a while, the emission controls might
not work as well, the 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 the vehicle warranty.
Notice: Modifications made to the engine,
transmission, exhaust, intake, or fuel system of
the vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle's emission
controls and can cause this light to come on.
Modifications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6‑3.

This light comes on during a malfunction in one of
two ways:
Light Flashing : A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
The following can prevent more serious damage to the
vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn off the ignition, wait at least 10 seconds, and
restart the engine. If the light is still flashing, follow the
previous steps and see your dealer/retailer for service
as soon as possible.
Light On Steady : An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required. An emission system malfunction might be corrected by
doing the following:
.Make sure the fuel cap is fully installed. See
Filling
the Tankon page 6‑9. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should
turn the light off.
.If the vehicle has been driven through a deep
puddle of water, the vehicle's electrical system
might be wet. The condition is usually corrected
when the electrical system dries out. A few driving
trips should turn the light off.
.Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run as
efficiently as designed and may cause: stalling
after start-up, stalling when the vehicle is changed
into gear, misfiring, hesitation on acceleration,
or stumbling on acceleration. These conditions
might go away once the engine is warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one full
tank of the proper fuel to turn the light off.
See Gasoline Octane on page 6‑7.
4-42

If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to fix
any mechanical or electrical problems that might have
developed.
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. See Ignition
Positions
on page 3‑23. Press the bottom of the
Acc. button on the instrument panel and hold the button down for five 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
briefly, less than five 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 Gauge
United StatesCanada
United States—Z06 and
ZR1 Models Canada —Z06 and ZR1
Models
{WARNING:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches fire.
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 gauge shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running.
Oil pressure should be 140 to 550 kPa (20 to 80 psi).
In certain situations such as long, extended idles on
hot days, it could read as low as 40 kPa (6 psi) 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. See Engine Oil on page 6‑19.
4-44

The engine oil pressure can also be displayed using the
GAGES button on the Driver Information Center (DIC).
See Driver Information Center (DIC) on page 4‑47.

Fuel Gauge
The fuel gauge shows
how much fuel the vehicle
has left while the engine
is on.
An arrow on the fuel gauge 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 filled 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 five things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gauge.
.At the service station, the gas pump shuts off
before the gauge reads the full.
.It takes a little more or less fuel to fill up than the
gauge indicated. For example, the gauge may
have indicated half full, but it took a little more or
less than half of the tank's capacity to fill the tank.
.The gauge pointer may move while cornering,
braking or speeding up.
.The gauge may not indicate the tank is empty
when the ignition is turned off.
.The gauge reading may change slightly within the
first several minutes after starting the vehicle.
See DIC Operation and Displays
on page 4‑47for
more information.

Boost Gauge (ZR1 Only)
United StatesCanada
For vehicles that have this gauge, it is located near the
driver side of the instrument panel cluster.
This gauge 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 gauge 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. See DIC Warnings and Messages
on page 4‑52for 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”
under Automatic Transmission Operation
on page 3‑26and“Head-Up Display (HUD)” in the index of the
