2008 CHEVROLET CORVETTE ignition

When the desired HUD display has been selected,
release the MODE button.
Within each mode, the display, can be further
customized by pressing the PAGE button. Pressing this
button in each mode will turn off and on the following:
Street Mode — No tachometer, circular tachometer,
and linear tachometer.
Track Modes 1 and 2 — No minor gage, coolant
temperature, transmission oil temperature, engine
oil temperature, and engine oil pressure.
While in Track Mode 1 or 2, the maximum G value
achieved during the current ignition cycle can be
displayed by pressing and holding the PAGE button.
The maximum G display will be shown until the
PAGE button is released. The maximum G value
display will be identical to the normal G value
display, except the maximum G gage digits (X.XX G)
and corresponding G gage bar will overwrite the
current G value.Be sure to continue scanning the displays, controls and
driving environment just as you would in a vehicle
without HUD. If you never look at your instrument panel
cluster, you may miss something important, such as
a warning light. Under important warning conditions,
the CHECK GAGES warning will illuminate in the HUD.
View your Driver Information Center (DIC) for more
information.

Clean the inside of the windshield as needed to remove
any dirt or lm that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry
it. Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.
If the ignition is on and you can not see the HUD
image, check to see if:
Something is covering the HUD unit.
The HUD dimmer control is adjusted properly.
The HUD image is adjusted to the proper height.
Ambient light is low, in the direction your vehicle
is facing.
A fuse is blown. SeeFuses and Circuit Breakers
on page 5-100.
Keep in mind that your windshield is part of the HUD
system. SeeWindshield Replacement on page 5-55.
Accessory Power Outlet(s)
The accessory power outlet can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The accessory power outlet is located inside the center
console storage compartment, on the forward left side.
To use the outlet, remove the tethered cap. When not
using it, always cover the outlet with the protective cap.
Notice:Leaving electrical equipment plugged in
for an extended period of time while the vehicle is
off will drain the battery. Power is always supplied to
the outlets. Always unplug electrical equipment
when not in use and do not plug in equipment that
exceeds the maximum 20 ampere rating.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer/retailer for additional
information on accessory power outlets.

These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
There is also an inside temperature sensor located to
the left of the ignition switch. The automatic climate
control system uses this sensor to receive information,
so if you block or cover it, the system will not function
properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
and moisture condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm the
passengers. Use defrost to remove fog or frost from the
windshield more quickly. To prevent fogging on the
inside of the windows in modes other than oor/defog
and defrost, make sure the air conditioning compressor
is on and recirculation mode is off.Press the mode button until the defog mode appears on
the display.
-(Floor/Defog):This mode directs the air equally
between the windshield and the oor outlets with a small
amount to the side window outlets. When you select
this mode, the system turns off recirculation and runs
the air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the defog mode.
1(Defrost):Pressing this button directs most of the
air to the windshield, with a small amount directed to the
side window outlets. The light on the button will come
on and the digital display will show the defrost mode
symbol and fan speed when the front defrost mode is
being used. In this mode, the system will automatically
turn off the recirculation and run the air-conditioning
compressor, unless the outside temperature is at
or below freezing. Recirculation cannot be selected
while in the defrost mode. Pressing this button again
will return the system to the last operating mode.
For severe ice conditions, turn the driver’s temperature
knob to 90°F (32°C) while in defrost mode.
Do not drive the vehicle until all the windows are clear.

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” under
DIC Vehicle Personalization on page 3-75.
To read the odometer with the ignition off, turn on the
parking lamps.
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/retailer 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 6500 rpm for the
base model and 7000 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 Reminders
Safety Belt Reminder Light
When the engine is started, 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 is 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.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey when the engine
is started.
That 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.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is
not on, the vehicle still has brakes, but not antilock
brakes. If the regular brake system warning light is also
on, the vehicle does not have antilock brakes and
there is a problem with the regular brakes. SeeBrake
System Warning Light on page 3-41.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-57for all
brake related DIC messages.
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 3-57
for 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 5-31for more
information.
Tire Pressure Light
This light comes on briey
when the engine is started.
This light also comes on when one or more of the tires
are signicantly underinated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDIC
Warnings and Messages on page 3-57for more
information.
Stop and check the tires as soon as it is safe to do so.
If underinated, inate to the proper pressure.
SeeTires on page 5-58for more information.
If a problem is detected with the Tire Pressure Monitor
System, this light ashes for approximately 60 seconds
and then stays on for the remainder of the ignition
cycle. SeeTire Pressure Monitor System on page 5-68
for more information. United States

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.
The check engine light
comes on to indicate
that there is an OBD II
problem and service
is required.
Malfunctions often are indicated by the system before
any problem is apparent. This can 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 a while, the emission controls
might not work as well, your vehicle’s fuel economymight 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 5-3.
This light comes on briey, as a check to show it is
working, as you start the engine. If the light does not
come on, have it repaired. This light also comes
on during a malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and could damage the emission control system on
your vehicle. Diagnosis and service might be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service might be required.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might 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 2-22. 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 — if you 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, 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/retailer can prepare the vehicle for inspection.
