Air Intake Control

~1min read

The air intake control button is used to select either fresh air mode (outside air) or recirculation mode (cabin air).

Recirculated Air Position

When the recirculated air position is selected, air from the interior will be drawn through the heating system and heated or cooled according to the selected function.

Outside (Fresh) Air Position

When the outside (fresh) air position is selected, air is drawn into the vehicle from outside and heated or cooled according to the selected function.

Information

Using the system in fresh air mode is recommended.

Running the heater continuously in the recirculated air position (without air conditioning) may cause the windshield and side windows to fog up, and the air inside the vehicle will become stale.

Also, prolonged use of air conditioning in recirculation mode will cause excessively dry air inside the vehicle.

WARNING

  • Continuous operation of the climate control system in the recirculated air position may allow humidity inside the vehicle to increase, which may fog the glass and reduce visibility.
  • Do not sleep in the vehicle with the air conditioning or heating system on. This may result in serious injury or death due to reduced oxygen levels and/or body temperature.
  • Continuous operation of the climate control system in the recirculated air position may cause drowsiness, and loss of vehicle control. Set the air intake control to the outside (fresh) air position as much as possible while driving.
