AIR VENT OPERATION
The vents can be opened using the following procedure:
To open the vent, rotate the thumb wheel fully upwards, from the bottom (closed) position to the (top) open position.
After the vent has been opened using the thumb wheel, the direction control can be used to adjust the direction of air flow.
The vent can only be fully closed again using the thumbwheel. The vent can be closed regardless of the position of the directional control.
Do not insert or attach items to the vents, for example, pens, air fresheners, etc.
Do not use excessive force while operating the vent control or the thumb wheel.
