@ Section 3 Comfort Controls and Audio Systems
In this section you'll find out how to operate the comfort
control and audio systems offered with your Aurora. Be
sure to read about the particular systems supplied with
your vehicle.
Comfort Controls
This section tells you how to operate your climate
control system. Your climate control system uses
ozone-friendly
R- 134a refrigerant.
Automatic Electronic Climate Control
Your Aurora is equipped with a Dual Zone Automatic
Electronic Climate Control System. You can use the
automatic setting or override the automatic setting
by using the manual controls. Your vehicle also has
the flow-through ventilation system described later
in this section.

If the display ever starts flashing after the automatic
electronic climate control system is started, there is a
problem with the electronic climate control system and
you should see your dealer for service.
AUTO-PUSH Knob
By pressing the AUTO-PUSH knob, you have selected
the electronic climate control system to be in the
automatic mode. The climate control system
will
automatically control the air temperature, air distribution

Automatic Operation
Press the AUTO-PUSH knob when you want the system
to automatically adjust to changes in the temperature
inside the vehicle, the outside temperature and the sun
load on the vehicle. When the system
is set for 4%
automatic operation, air will come from the floor, upper
or the windshield outlets depending on the temperature
inside the vehicle, the outside temperature and the sun
load. Fan speed will vary as the system reaches and
.................
maintains the comfort setting you have selected.
. 7* -
....................................................................... \
To find your comfort setting, start with the system in
automatic mode by depressing the AUTO-PUSH knob.
Adjust
the comfort setting by using the red and blue
buttons located below the digital display until you reach a
value of
75 OF (24"C), on the display. Give the vehicle
about
20 minutes to stabilize and then adjust the comfort
setting
if necessary, through the use of the red and blue
buttons. The display will show
the comfort setting for five
seconds and then it will show the outside temperature.
In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length
of the delay
depends on the engine coolant temperature and the
outside temperature. Rotating the AUTO FAN knob will
override this delay by turning off the automatic fan
mode and changing the fan speed. Your
automatic electronic climate control system has
two sun sensors located on the top of the instrument
panel that detect direct sunlight. To keep you and your
passengers comfortable, the system may supply cooler
air to the
side towards the sun. Be careful not to put
anything over these sun sensors. The automatic
electronic climate control system may not operate
correctly if these sensors are covered.
To change the automatic electronic climate control
display from an English display to a Metric display, hold
down the OFF button located in the Driver Information
Center for five seconds. The display in the Driver
Information Center will also change from an English to
a Metric display.
To return to an English display, repeat
the above procedure.

You may override the automatic airflow distribution by
rotating the AUTO-PUSH knob. After you rotate this
knob, the comfort setting will be displayed for five
seconds then the outside temperature will be displayed.
The fan control will remain in the automatic control
mode unless you rotate the AUTO FAN knob to select a
manual fan speed.
@*
fl Upper: Directs airflow through the upper air
outlets located in the instrument panel and door panels.
fl Bi-Level: Directs the airflow through both the
upper air outlets and the lower floor outlets. There is
also a small amount
of air directed to the front defroster
and the side window defrosters.
$/ Heat: Directs most of the airflow to the lower
floor outlets with some airflow directed to the side
window defrosters. There is also a small amount of
airflow directed to the front defroster.
eo
@?
' / Defog: Directs the majority of the airflow to the
lower floor outlets and the front defroster. A small
amount of airflow is directed
to the side window
defroster outlets. This mode can be useful to remove the
moisture from the inside
of the windshield when the
outside temperature is cold or the humidity is high.
DEF (Defrost): Directs the majority of the airflow
to the windshield with some airflow to the side window
defrosters and lower floor outlets. To increase the fan
speed, rotate the AUTO FAN knob to the right.
RECIRC: Press this button to limit the amount of
outside air entering your vehicle. This is helpful when
you are trying to cool the interior of the vehicle quickly
or limit the amount of outside air entering your vehicle
for some other reason. The RECIRC button and the
AUTO-PUSH knob may be selected at the same time.
The system will remain in RECIRC
for 12 minutes or
until the ignition is turned off, then the system will
return back
to the previously selected mode. RECIRC
may be selected in all manual airflow modes except
FRONT Defrost.

Operating the RECIRC mode in cold temperatures or
under high humidity conditions may cause moisture to
form on the inside of the windshield. If this condition
occurs, deselect the RECIRC button.
A/C ON: Press this button to turn the air conditioning
on and off. If the system is operating in the automatic
mode, the A/C
ON indicator light will automatically
illuminate.
In the auto mode, the A/C compressor will
only operate when the system determines it is needed.
OFF: Rotate the AUTO-PUSH knob to the OFF
position. Turning the system off will cause the fan to
turn off and the airflow to be directed out the lower floor
outlets. The system will still try to keep the interior of
the vehicle at the previously chosen comfort setting. The
outside temperature will show in the display when the
system is
OFF.
Air Conditioning
The air conditioner cools, dehumidifies and filters the
air for the inside of the vehicle.
The air conditioning compressor is enabled in all
modes unless the A/C
ON button is in the off position
(indicator light will not be illuminated). However, the
air conditioning compressor will not operate when the
outside temperature is below 44°F
(7 "C). When the
air conditioner is on, you may sometimes notice slight
changes in your vehicle's engine speed and power. This
is normal, because the system is designed to cycle the
compressor on and off
to keep the desired cooling and
help fuel economy.
On very hot days, open the windows long enough to let
the hot
air out. This reduces the time required to cool the
interior of the vehicle to a comfortable level.
If the
system is in the automatic mode (AUTO-PUSH knob
indicator light
is on), during very hot days the system
will automatically
go to the RECIRC mode and the
temperature door will
be positioned at the full cold position
for maximum cooling. You can choose the extreme comfort setting of
60°F ( 16 " C), but the system will not cool any
faster by choosing the extreme comfort setting.

Heating
In cold weather, if the automatic mode is selected
(AUTO-PUSH knob indicator light is on), the system
will automatically direct the airflow out
of the lower
floor outlets and the temperature door will be positioned
at the full hot position. You can choose the extreme
comfort setting of
90°F (32°C) but the system will
not warm up
any faster by selecting the extreme
comfort setting.
In cold weather, the system will delay turning on the
fan to avoid blowing cold air. The length
of the delay
depends on the engine coolant temperature and the
outside temperature. The fan speed will increase as the
temperature
of the engine coolant increases. Rotating the
AUTO
FAN knob will override this delay by turning
off the automatic
fan control mode and changing the
fan speed.
t
Ventilation System
Your Aurora’s flow-through ventilation system always
allows outside air to flow through your vehicle when
it
is moving, even when the system is in the OFF position. The
direction
of the air can be controlled by adjusting or
closing the outlets in the instrument panel. Rotate the
control between the front outlets upward to open the
outlets and downward to close the outlets. Adjust the
direction
of airflow from side to side with the controls in
each outlet.
