Low oil pressure may be the result of a combination
of low oil level and abrupt changes in the vehicle's
direction. When this warning is displayed, you should
not operate the engine at high rpm or make fast abrupt
moves. As soon as possible, you should check the oil
level. See ªEngine Oilº in the Index.
LOW OIL LEVEL: Press RESET to acknowledge
that you have read the message and to remove it from
the display. The message will reappear every 10 minutes
until this condition changes. Once the vehicle senses
a temperature change in the engine oil, the light will
remain off.
You will hear two chimes when this message is
displayed. If this message appears after starting your
engine, your engine oil level may be too low. You may
need to add oil. See ªEngine Overheatingº in the Index.

Head-Up Display (HUD) (If Equipped)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. The HUD consists of the
following information:

Speedometer

Turn Signal Indicators

High
-Beam Indicator Symbol

Tachometer

Oil, Temperature and Fuel Gages

Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle's best performance level has been
reached to shift the transmission into the next
higher gear. The SHIFT light will display at an
engine speed of about 5,750 rpm (6,250 rpm
on Z06), just prior to reaching the engine fuel
cut
-off mode. To better understand the vehicle's
power curves, see ªCapacities and Specificationsº
in the Index.

Fuel Level
The selections that you choose will remain in the
HUD display until they are changed.
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 icon will illuminate in
the HUD. View your Driver Information Center (DIC)
for more information.

(Defog): This setting divides the air between the
windshield and lower outlets with a small amount of air
directed toward the side window vents. This is useful
when fog appears on the windshield or side glass due to
rain or snowy conditions.
(Defrost): Use this setting to quickly remove fog or
frost from the windshield. This setting directs most of
the airflow to the windshield with a small amount of air
directed toward the lower and side window outlets.
Mode Buttons
These buttons control the air intake, the air conditioning
and the rear window defogger operation.
(Outside Air): Press this button and it will bring
outside air into the vehicle. The light on the button will
come on when operating. Use this setting while trying to
defrost or defog windows to help clear moisture.
(Recirculate): Press this button to limit the amount
of outside air entering the vehicle by recirculating most
of the air inside the vehicle. The light on the button will
come on when operating. This setting is helpful when
you are trying to cool the air quickly or to limit odors
entering the vehicle. Recirculate cannot be used while in
the defrost or defog modes.Operating the system in the recirculation mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
system to either the defog or defrost mode and increase
the fan speed. To avoid re
-fogging of the windows,
operate the system in the outside air mode.
A/C (Air Conditioning): This button turns the
air conditioning compressor off or on under most
conditions. The light on the A/C button comes on
when the compressor is operating. The air conditioning
does not operate at temperatures below approximately
35
F to 40
F (2
C to 4
C). The air conditioning
cools and dehumidifies the air coming into the vehicle.
The air conditioning cannot be turned off in defrost,
as it helps to remove moisture from the vehicle. It also
helps to keep the windows clear.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures.
See ªRear Window Defoggerº later in this section for
more information.

3-8
Function Buttons
These buttons control the climate control ON/OFF,
air intake, front defrost, rear defrost and the air
conditioning operation.
OFF: Press the OFF button to turn off the climate
control system. This is the only setting that fully
shuts off the fan. The digital display will show only the
outside temperature. You can still adjust the driver set
temperature, the passenger temperature offset and the
air intake mode while in OFF.
A/C (Air Conditioning): This button turns
the air conditioning compressor off or on under most
conditions. The light on the A/C button will come on
when the compressor is operating in either the automatic
or manual mode. The air conditioning does not operate
at temperatures below approximately 35
F to 40
F
(2
C to 4
C). The light on the A/C button will flash if
pressed when air conditioning is not available. The air
conditioning cools and dehumidifies the air coming into
the vehicle. 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.If the system is operating in the AUTO mode, turning
the air conditioning off will delete AUTO from the
digital display and show current mode and fan settings.
The AUTO button must be pressed to return to the
automatic mode operation.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures.
(Outside Air): Press this button to provide outside
air. The light on this air intake button will come on to
show when it is operating. When in the AUTO mode,
the system automatically selects outside air instead of
recirculate, as required, to control the temperature in the
vehicle. By pressing outside air, the system will lock
into the outside air mode. Any adjustment to the air
intake must then be made manually. Outside air should
be used when trying to defrost or defog windows to help
reduce moisture inside of the vehicle.

Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling discs. Pick up discs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
Fixed Mast Antenna (Z06)
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, you can straighten it out by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast is still
tightened to the rear quarter panel.
