2007 CHEVROLET CORVETTE ignition

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.

Anti-Lock Brake System
Warning Light
With the Anti-Lock
Brake System (ABS),
this light will come on
when the engine is
started and may stay on
for several seconds.
If the light stays on, turn the ignition off. 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 214.
The ABS 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.
Traction Control System (TCS)
Warning Light
This light should come
on briey as you start
the engine. If the
light does not come
on then, have it xed
so it will be ready
to warn you if there
is a problem.
If it stays on, or comes on and the Driver
Information Center (DIC) shows a SERVICE
TRACTION SYSTEM message when you
are driving, there is a problem with your Traction
Control System (TCS) and your vehicle needs
service. When this light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
If the driver turns off the TCS by pressing the
button on the console, the TCS light will come
on and the TRACTION SYSTEM OFF message
will show on the DIC. SeeDIC Warnings and
Messages on page 214for more information.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the shaded area,
your engine is too hot.
This means that your engine coolant has
overheated. If you have been operating your
vehicle under normal driving conditions, you should
pull off the road, stop your vehicle and turn off
the engine as soon as possible.
SeeEngine Overheating on page 350for more
information.
Tire Pressure Light
This light will come on
briey when you turn
the ignition on.
This light will also come on when one or more of
your tires are signicantly underinated.
A LOW TIRE PRESSURE message in the Driver
Information Center (DIC) will accompany the light,
seeDIC Warnings and Messages on page 214
Stop and check your tires as soon as it is safe to do
so. If underinated, inate to the proper pressure.
SeeTires on page 378for more information.
This light will ash for about 60 seconds and
then turn on solid if a problem is detected with
the Tire Pressure Monitor system.

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.

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.

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.
