The air distribution handle is used to change the direction of the air flow.
With its help you can set one of five air supply modes:
Front Zone (
)
When this mode is set, air is supplied through the central and side ventilation grilles.
Two-level blowing (
)
Air flows in two directions. Half of the flow goes through the lower vents, and the rest of the flow goes through the central and side vents.
Leg area (
)
The main air flow comes through the lower vents. Air comes through the windshield defroster nozzles, side vents and rear vents. For normal air flow to the rear of the cabin, the space under the front seats must be free
Legs/window blowing (
)
In this mode, the main part of the air flow is directed through the windshield defroster nozzles, the door window defroster nozzles and the footwell air nozzles. A small amount of air is also directed to the side nozzles.
Glass blowing (
)
The main part of the air flow is directed through the windshield defroster nozzles and the door window defroster nozzles. A small amount of air is also directed to the side nozzles.
