GF83.10-P-2182-02Q Air Ducting, Function

Function

Center nozzle
The direction of air flow can be controlled via the separately adjustable slats at the center nozzle as desired, either upwards, downwards to the left or right or even to the center.
Using the adjustment wheels, the center nozzle can be opened and closed, individually for each side.
To open, turn the adjustment wheels upward.
Using the cold-air mix adjustment wheel located in the center of the center nozzle, cold air can be mixed in, which then flows out of the ventilation nozzle at the front to provide a temperature difference between footwell and headroom (warm feet, cool head).

Fresh air vent
The fresh air vent can be opened and closed via the adjusting wheel which is located centrally.
No further adjustment options exist.
The draft appearances possibly caused by the center nozzle and side nozzles can be reduced by opening the fresh air vent.

Right and left lateral nozzle
The direction of air flow can be controlled via the separately adjustable slats at the lateral nozzle as desired, either upwards, downwards to the left or right or even to the center.
To open, turn the adjustment wheel upward.
The lateral nozzle is closed when the adjustment wheel is turned downward all the way.

Defroster vents for windshield and left and right side windows
The air supply to the windshield and left and right side windows defroster vents can be opened and closed via the defroster buttons on the AAC [KLA] control and operating unit (N22) (on vehicles without code (581b) comfort automatic air conditioning) or via the comfort AAC (C-AAC [K-KLA]) control and operating unit (N22/7) (on vehicles with code (581b) comfort automatic air conditioning).
A separate adjustment option does not exist.
Temperature-controlled air flows out of the defroster vents.

Under the following conditions cooled air can also flow out in automatic operation:

^ a configured automatic air distribution
^ dry weather (recognition of humidity by the humidity sensor (B31/2) or C-AAC [K-KLA] multifunction sensor (B31)) in order to keep the windows free from misting up.

As a result a longer opening time of the defroster vents is achieved and thus a more pleasant ventilation of the vehicle interior.

Footwell air outlet at front left and right
The air supply for the front footwell air outlet can be opened and closed via the air distribution switch in the AAC [KLA] control and operating unit (N22) or the comfort AAC (C-AAC [K-KLA]) control and operating unit (N22/7). A separate adjustment option does not exist. Temperature-controlled air flows out of the front footwell air outlet.

Rear footwell air outlet at left and right
The air supply for the rear legroom air outlet can be opened and closed via the air distribution switch in the AAC [KLA] control and operating unit (N22) or the comfort AAC (C-AAC [K-KLA]) control and operating unit (N22/7). A separate adjustment option does not exist. Temperature-controlled air flows out of the rear footwell air outlet.

Rear footwell air outlet at left and right
The air supply for the rear legroom air outlet can be opened and closed via the air distribution switch in the AAC [KLA] control and operating unit (N22) or the comfort AAC (C-AAC [K-KLA]) control and operating unit (N22/7). A separate adjustment option does not exist. Temperature-controlled air flows out of the rear footwell air outlet.

Rear compartment nozzle
The direction of air flow can be set by means of two individually- adjustable slats as desired, upwards, downwards, to the left and right.
The rear compartment nozzle can be opened and closed as well as the air quantity regulated using the air quantity adjusting wheel. To open, turn the air quantity adjusting wheel upwards.

Air inlet
The air inlet serves to route the fresh air required for ventilation purposes from the ventilation slots in the engine hood to the fresh air flap.
Any penetrating water is collected by the water collector and routed outwards by the water drainage.

Rear vent
The slatted-type flaps mounted in the rear vent open because of the head pressure of the air flowing through the vehicle ultimately allowing it to exit.
In the event of a vacuum in the vehicle, such as when driving with the window or sunroof open, the flaps will close on their own through gravitational forces. This way they prevent any exhaust fumes, dust or humidity from being drawn into the car.

Stowage compartment air vent
Open ventilation nozzle for stowage compartment: slide lever downward.
Close ventilation nozzle for stowage compartment: slide lever upward.

The air quantity which is supplied depends on:
^ the air distribution duct setting,
^ the air quantity setting,
^ the opening position of the storage compartment ventilation nozzle

The air required to ventilate the storage compartment is drawn from the rear nozzle air duct.
The air is able to escape into the rear footwell via a ventilation grill.
The air temperature corresponds approximately to the temperature-controlled air emitted from the rear nozzles. This cannot be separately adjusted.

As a result of the confined spatial conditions, extreme temperatures may occur in the stowage compartment. In the case of heat-sensitive goods, therefore, the ventilation nozzle may be closed during heater operation. Do not cover the storage compartment ventilation nozzle with objects.
