Automatic Operation
AUTO (Automatic): The system automatically controls the inside temperature, the air delivery, and the fan speed.
To use automatic mode:
1. Press the AUTO button.
When AUTO is selected, the current temperature(s) selected and AUTO is shown on the display. The current air delivery mode and fan speed also appear for approximately five seconds.
When AUTO is selected, the air conditioning and air inlet are automatically controlled.
The air conditioning runs when the outside temperature is over 4°C (40°F). The system is automatically set to outside air, unless it is hot outside and then the air inlet changes to recirculation mode to help quickly cool the vehicle.
The recirculation indicator light will come on.
2. Set the temperature for the driver and passenger.
To find a comfortable setting, start with a 22°C (73°F) temperature setting and allow about 20 minutes for the system to regulate. Use the driver side or passenger side temperature buttons to adjust the temperature setting as necessary. The system will remain at the selected setting.
Choosing the warmest or coolest temperatures does not cause the vehicle to heat or cool more quickly.
To avoid blowing cold air in cold weather, the system delays turning on the fan until warm air is available. Press the fan control to override this delay and select the fan speed.
