2005 CHEVROLET CORVETTE engine

If your vehicle is equipped
with a navigation radio,
many of the turn-by-turn
navigation features
will also be displayed on
the HUD if you are in
Street Mode.
Be sure to continue scanning your 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 not see 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.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 your 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 your 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.

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, see
Passenger Compartment Air Filter on page 3-31and
Scheduled 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.
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.

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.
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 is equipped with 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 your 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
odor and 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 5-12.
To check or replace the air lter, do the following:
1. Disengage the passenger compartment air lter
housing cover retainer clips (1).
2. Remove the passenger compartment air lter
housing cover.

3. Remove the passenger compartment air lter from
the housing.
4. Insert the new lter into the housing.
5. Reinstall the passenger compartment air lter
housing cover.
6. Engage the passenger compartment air lter
housing cover retainer clips.
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 3-49.

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 3-69.
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. 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 be provided
for several seconds to remind people to buckle their
safety belts. The driver safety belt light will also be
provided and stay on for several seconds, then it will ash
for several more. You should buckle your seat belt.
This chime and light will be
repeated if the driver
remains unbuckled and the
vehicle is in motion.
If the driver’s belt is buckled, neither the chime nor the
light will be provided.

{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the passenger’s
frontal airbag and side impact airbag
(if equipped), it means that something may
be wrong with the airbag system. The
passenger’s frontal airbag and side impact
airbag (if equipped) could inate even though
the switch is off. If this ever happens, do not
let anyone whom the national government has
identied as a member of a passenger airbag
risk group sit in the passenger’s position
(for example, do not secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 1-48.
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),
you are going 15 to 19 mph (24 to 31 km/h) and
you are 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 2-30
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.
