Manual Operation Automatic Operation AUTO (Automatic): The system automatically controls fan speed, air delivery, and air conditioning in order to heat or cool the vehicle to the desired temperature.

Adjust the temperature to a comfortable setting between 21°C (70°F) and 27°C (80°F). Choosing the coldest or warmest temperature setting will not cause the system to heat or cool any faster.

The system starts out blowing air at the floor, but can automatically change modes Q / R (Temperature Control): The temperature can be adjusted separately for the driver and the passenger. Press to increase or decrease the automatic temperature settings. PASS (Passenger Climate Control): Press to set a different temperature for the passenger.
