Download manual 2019 Nissan MaximaManual Description
The sunload sensor, located on the top center of the instrument panel, helps the system maintain a constant temperature. Do not put anything on or around this sensor. When the climate system is in automatic operation and the engine coolant temperature and outside air temperature are low, the air flow outlet may default to defroster mode for a maximum of 2 minutes 30 seconds.
This is not a malfunction. After the engine coolant temperature warms up, the air flow outlet will return to foot mode and operation will continue normally. When the outside and interior cabin temperatures are moderate to high, the intake setting may default to turn off air recirculation to allow fresh air into the passenger compartment.
You may notice air flow from the foot mode, bi-level mode or side demist vent outlets for a maximum of 15 seconds. This may occur when the previous climate setting was turned off. This is not a malfunction. After the initial warm air is expelled, the intake will return to automatic control, the air flow outlet will return to previous settings, and operation will continue normally. To exit, press any climate control button.
