There are three HUD modes that you can choose to
view in the HUD display. By pressing the MODE
button, you can scroll through these modes in the
following order:
Street Mode supports
audio and navigation
functions with your
choice of tachometer
settings.
Track Mode 1 supports
the G-Force gage and
minor gages with a
circular tachometer.
Track Mode 2 supports
G-Force gages and
minor gages with
a linear tachometer.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 and2—Nominor 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.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.

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 186andScheduled Maintenance on
page 433.
?(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.
182

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 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 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 433for 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 330.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
on your vehicle. The pictures help to 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 the 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 the details show 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 as 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 vehicle’s warning lights
and gages. They can be a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information Center
(DIC) on page 207for more information.

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.
