Operating tips
● When the engine coolant temperature and outside air temperature are low, the air flow from the foot outlets may not operate for a maximum of 150 seconds. However, this is not a malfunction. After the coolant temperature warms up, air flow from the foot outlets will operate normally.

The sunload sensor, located on the top of the instrument panel on the driver’s side, helps the system maintain a constant temperature. Do not put anything on or around this sensor.
