| Compressor | : ON |
| Air outlet | : DEF |
| Air inlet | : FRE (Fresh air intake) |
| Blower fan speed | : AUTO |

WHEN AMBIENT TEMPERATURE IS 3°C (37°F) OR MORE, OR ENGINE COOLANT TEMPERATURE IS 56°C (133°F) OR MORE
| Compressor | : ON |
| Air outlet | : AUTO |
| Air inlet | : 20% FRE (20% fresh air intake) |
