Door Mounted Vents
The door vents are also controllable and can be set to suit the occupants
requirements.
A lever at the top of each door vent controls the distribution and volume of
air.
In the mid position, unrestricted airflow is available from the door vent and
the side window vent.
Moving the lever towards the window symbol progressively closes off the
door vent and biases airflow to the side window vent.
•
Moving the lever towards the symbol progressively closes off the airflow
to both side window and door vents. This lever position may be used during
demist operations to ensure maximum airflow to the windscreen.
