engine CHEVROLET CORVETTE 2008 6.G Owner's Guide

The HUD controls are
located to the left of the
steering wheel.
To adjust the HUD so you can see it properly, do the
following:
1. Start the engine and press the HUD dimmer control
all the way up by pressing the (+) button.
The brightness of the HUD image is determined by
the light conditions in the direction the vehicle is
facing and where you have the HUD dimmer control
set. If you are facing a dark object or a heavily
shaded area, your HUD may anticipate that you are
entering a dark area and may begin to dim.
It is possible for sunlight to enter the HUD making it
difficult to see the image. The display will return
to normal when the sunlight is no longer entering
the HUD.2. Adjust the seat to a comfortable driving position.
If you change your seat position later, you may
have to re-adjust your HUD.
3. Press the up or down arrows to center the HUD
image in your view.
The HUD image can only be adjusted up and down,
not side-to-side.
4. Press the dimmer control downward until the HUD
image is no brighter than necessary.
To turn HUD off, press and hold the (–) button until the
HUD display turns off.
If the sun comes out or it becomes cloudy, you may
need to adjust the HUD brightness again using
the dimmer control. Polarized sunglasses could make
the HUD image harder to see.
The HUD information can be displayed in one of
six languages including English, Spanish, French,
German, Italian or Japanese. The speedometer can be
displayed in either English or Metric units.
To change the language and unit selections, see
“OPTION” underDIC Operation and Displays on
page 3-52.

x9w(Fan):Press the button with the fan symbol
to manually increase or decrease the fan speed.
Keep pressing the up or down arrow on this switch until
the desired fan speed appears on the display.
Pressing the arrows will delete AUTO from the digital
display. The fan graphics with the fan speed bars will be
shown. To increase the fan speed so that more air
ows into the vehicle, press the up arrow on the
fan switch. To decrease the fan speed and airow,
press the down arrow. The AUTO button must be
pressed to return to the automatic fan control.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter
may need to be replaced. For more information,
seePassenger Compartment Air Filter on page 3-32
andScheduled Maintenance on page 6-4.
?(Recirculation):Press this button to turn the
recirculation mode on or off. When the climate control
system is in recirculation mode an indicator light will
come on. This mode prevents outside air from entering
your vehicle. It can be used to prevent outside air and
odors from entering your vehicle and to help cool the air
inside your vehicle more quickly. Recirculation mode is
not available in defrost or defog mode.
^(Air Conditioning Off):Press this button to turn the
air conditioning compressor off. Press AUTO to return
to automatic operation. When in AUTO, the air
conditioning compressor will come on automatically,
as needed.
Air conditioning does not operate at temperatures below
about 35°F to 40°F (2°C to 4°C). In temperatures
above 40°F (4°C), the air conditioning cannot be turned
off in defrost and defog, as it helps to remove moisture
from the vehicle. It also helps to keep the windows clear.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
3-28

For quick cool down on hot days press the AUTO button
and adjust the temperature to a cool, comfortable setting.
To achieve maximum cool down, do the following:
1. Select the vent mode.
2. Select recirculation mode.
3. Select the A/C on.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become
too dry. To prevent this from happening, after the air
in your vehicle has cooled, turn the recirculation
mode off.
The air conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.Sensors
The solar sensor on your vehicle monitors the solar
radiation and uses the information to maintain the
selected temperature when operating in AUTO mode by
initiating needed adjustments to the temperature, the
fan speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing
the sun. The recirculation mode will also be activated,
as necessary. Do not cover the solar sensor located on
the top of the instrument panel near the windshield or
the system will not work properly.
There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps to maintain the temperature inside the vehicle.
Any cover on the front of the vehicle could give a false
reading in the temperature.
If the outside temperature goes up, the displayed
temperature will not change until:
The vehicle’s speed is above 12 mph (19 km/h)
for ve minutes.
The vehicle’s speed is above 32 mph (52 km/h)
for two and a half minutes.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
engine is running.
=(Rear Window Defogger):Press this button to turn
the rear window defogger on. Be sure to clear as much
snow from the rear window as possible. An indicator
light in the button will come on to let you know that the
rear window defogger is activated.
The rear window defogger will turn off about 10 minutes
after the button is pressed when traveling less than
30 mph (48 km/h). If turned on again, the defogger will
only run for about ve minutes before turning off.
The defogger can also be turned off by pressing the
button again or by turning off the engine.Your vehicle has heated outside rearview mirrors.
The mirrors will heat to help clear fog or frost from the
surface of the mirrors when the rear window defog
button is pressed.
If your vehicle has the power convertible top, the rear
window defogger and heated mirrors are automatically
disabled when the power convertible top is moving
or down.
Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by the vehicle warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.

Outlet Adjustment
Use the tab located on the air outlets to change the
direction of the airow.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter removes certain
particles from the air including pollen and dust particles.
Reductions in airow, which may occur more often in
dusty areas, indicate that the lter may need to be
replaced. SeeScheduled Maintenance on page 6-4for
information on how often to replace the lter.
Notice:Driving without a passenger compartment
air lter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the old
lter with a new one.
The passenger compartment air lter is located on the
passenger side of the engine compartment near the
battery. SeeEngine Compartment Overview on
page 5-14.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briey when you start the engine
just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section
that tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly — and even dangerous. So please get to know
your warning lights and gages. They are a big help.
Your vehicle has a Driver Information Center that works
along with the warning lights and gages. SeeDriver
Information Center (DIC) on page 3-51.

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.
3-36

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol. The
system checks the airbag’s electrical system for
malfunctions. The light indicates if there is an electrical
problem. The system check includes the airbag
sensor, the pretensioners, the airbag modules, the
wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 1-43.
This light comes on when
the vehicle is started,
and ashes for a
few seconds. The light
should go out when
the system is ready.
If the airbag readiness light stays on after the vehicle is
started or comes on while driving, the airbag system
may not work properly. Have your vehicle serviced
right away.{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away.
The airbag readiness light should ash for a few seconds
when the engine is started. If the light does not come on
then, have it xed immediately. If there is a problem with
the airbag system, an airbag Driver Information Center
(DIC) message may also come on. SeeDIC Warnings
and Messages on page 3-57for more information.
3-37

Voltmeter Gage
The voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel
cluster and other systems may shut down. The Driver
Information Center (DIC) will read BATTERY VOLTAGE
LOW when your vehicle is at 10 volts or below.
Have it checked right away. Driving with the voltmeter
reading at 10 volts or below could drain your battery
and disable your vehicle.
One-to-Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to turn off
this feature. This helps you get the best possible fuel
economy.
After shifting to FOURTH (4), you may downshift to a
lower gear if you prefer.
Notice:Forcing the shift lever into any gear except
FOURTH (4) when the 1 TO 4 SHIFT light comes
on may damage the transmission. Shift only from
FIRST (1) to FOURTH (4) when the light comes on.
This light will come on when:
The engine coolant temperature is higher than
169°F (76°C),
the vehicle is going 15 to 19 mph (24 to 31 km/h) and
the vehicle 21 percent throttle or less.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
This light should come on when you start the engine.
If it does not come on then, have it xed so it will
be ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-32
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.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. See
Towing Your Vehicle on page 4-29andDIC Warnings
and Messages on page 3-57for more information.
{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. United States
