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

Comfort Controls
This section tells you how to make your air system work
for you.
With these systems, you can control the heating,
cooling and ventilation in your vehicle. Your vehicle
also has a flow
-through ventilation system described
later in this section.
Manual Comfort Controls
Fan Knob
(Fan): The left knob controls the force of air you
want. Turn the knob clockwise to increase fan speed or
counterclockwise to decrease fan speed. The fan must be
turned on for the air conditioning compressor to operate.Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn it counterclockwise
(toward the blue area) for cooler air. Turn it clockwise
(toward the red area) for warmer air.
Mode Knob
The right knob selects the location of where the air will
enter the vehicle.
(Vent): This setting directs most of the air through
the instrument panel outlets with a very small amount of
air directed to the lower outlets.
(Bi-Level): This setting directs air into the vehicle
in two ways. Cooler air is directed toward your upper
body through the instrument panel outlets, while warmer
air is directed through the lower outlets.
(Floor): This setting directs most of the air through
the lower ducts to the floor area of the vehicle with
some of the air also directed toward the windshield and
side window vents.

A Typical Cold Weather Example:
Your vehicle has been parked outside overnight in
cold weather (below 32
F/ 0
C) and you have set the
driver temperature at 73
F (23
C) and have selected
the AUTO mode. The system will automatically adjust
the temperature output to maximum heating. The fan
will start at a low speed. This is to avoid blowing cold
air into the vehicle. The length of the delay depends on
the amount of time since the engine was last started, the
outside temperature and the engine coolant temperature.
As the coolant warms up, the fan speed will gradually
increase. Air will flow to the floor with some air to
the windshield to prevent fogging under most
normal conditions.
As the interior of the vehicle warms up to the set
temperature, the fan speed will decrease and the
temperature output may become cooler. If the interior
temperature continues to warm up due to heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically defog
or bi
-level).A Typical Hot Weather Example:
The vehicle has been parked outside all day in hot
weather (above 80
F/ 27
C) and you have set the
driver temperature at 73
F (23
C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum cooling. The fan will
start at a low speed momentarily to push the hot air to
the floor of the vehicle and then go to a higher fan speed
with cold airflow out of the instrument panel outlets.
A small amount of airflow will continue through the
lower ducts to cool the floor area.
The air intake may start in the recirculated mode for
maximum cooling performance. As the interior of the
vehicle cools down to the set temperature, the fan speed
will decrease and the temperature output may become
warmer. The air intake may shift from recirculation to
outside air mode. If the interior continues to cool due to a
decrease in the amount of heat the vehicle is absorbing
from the sun or a decrease in the outside temperature, the
system could switch to other air delivery modes (typically
bi-level or defog).

Manual Settings
With the automatic electronic dual climate control
system, there are several manual settings you can use
to control the system and override the AUTO operation.
You can program the fan speed, air delivery mode, air
intake mode and control the air conditioning operation
using these settings. The system will still determine the
temperature output level based on the driver
-set
temperature and the passenger temperature offset.
(Fan Speed): Press the button with the fan symbol
on it to manually lock in the current fan speed and to
stop the automatic fan speed control. 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 flows into
the vehicle, press the up arrow on the fan switch.
To decrease the fan speed and airflow, press the down
arrow. The AUTO button must be pressed to return
to the automatic fan control.MODE: Press the MODE button to manually lock in
the current air delivery setting and to stop the automatic
mode control. Pressing the MODE button will delete
AUTO from the digital display and the mode graphics
will be shown. To change the setting, press the MODE
button again. The AUTO button must be pressed to
return to the automatic mode selection.
(Vent): This setting directs most of the air through
the instrument panel outlets and a very small amount to
the lower outlets.
(Bi-Level): This setting directs air into the vehicle
in two ways. Cooler air is directed toward your upper
body through the instrument panel outlets, while warmer
air is directed through the lower outlets.
(Floor): This setting directs most of the air to the
floor area and some of it toward the windshield and side
window vents.
(Defog): This setting divides the air between
the windshield and lower outlets and a small amount
toward the side window vents. This is useful when fog
appears on the windshield or side glass due to rain or
snowy conditions.
