ignition CHEVROLET CORVETTE 2005 6.G Owner's Guide

If the light comes on while you are driving and you have
a CHECK BRAKE FLUID message showing on the
DIC, pull off the road and stop carefully. You may notice
that the pedal is harder to push. Or, the pedal may
go closer to the oor. It may take longer to stop. If the
light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 4-36.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service.
Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the light stays on, turn the ignition off. Or, if the light
comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on,
or comes on again while you are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
“SERVICE ANTILOCK BRAKES” underDIC Warnings
and Messages on page 3-54.
The anti-lock brake system warning light will come on
briey when you turn the ignition on. This is normal.
If the light does not come on then, have it xed so it will
be ready to warn you if there is a problem.

Tire Pressure Light
This light should come on
briey as you start the
engine. It will then come on
only when a at or low
tire pressure condition
exists.
SeeTire Pressure Monitor System on page 5-60for
more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with 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.

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 2-21. 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 press the bottom of
the ACC button only briey, less than ve seconds, the
accessory 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 your battery or if your
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 GM dealer can prepare the
vehicle for inspection.

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.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 3-49for 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.
If a problem is detected, a warning message will appear
on the DIC display. Be sure to take any message that
appears on the display seriously and remember that
clearing the message will only make the message
disappear, not correct the problem.
