Automatic Operation
The system automatically controls the fan speed, air delivery, air conditioning, and recirculation in order to heat or cool the vehicle to the desired temperature.
When the AUTO indicator light is on, the system is in full automatic operation. If the air delivery mode, fan speed, recirculation, or air conditioning setting is adjusted, the AUTO indicator turns off and the selected settings will appear on the display.
To place the system in automatic mode do the following:
1. Press AUTO.
2. Set the temperature. Allow the system time to stabilize. Adjust the temperature as needed for best comfort.
To improve fuel efficiency and to
cool the vehicle faster, recirculation
may be automatically selected in
warm weather. The recirculation
light will not come on. Press 
to
select recirculation; press it again to
select outside air.
TEMP
(Driver and Passenger
Temperature Control): The
temperature can be adjusted
separately for the driver and the
passenger. Press to increase or
decrease the temperature.
ZONE: Press to link all climate zone settings to the driver settings.
The ZONE indicator light will turn off. When the passenger settings are adjusted, the ZONE indicator light is on.
