REAR FOOTWELL AIR VENT FUNCTION - GF83.10-P-2110-01GC

Function

The air supply to the rear footwell air vent can be opened and closed via the air distribution switch.

There is no separate adjusting facility. Temperature-controlled air comes out of the rear footwell air vent.

REAR FOOTWELL AIR VENT FUNCTION - GF83.10-P-2110-01GI

The air supply to the rear footwell air vent can be adjusted by operating the rear compartment air distribution
switch (

) and the rear air distribution flap actuator motor (M2/21) that it actuates.

The quantity of air can be adjusted by operating the blower button (

) and the rear blower motor (M2/1) that

it actuates.

Pressing the Auto button (

) causes the automatic air conditioning push-button control module to regulate

the supply of air to the rear footwell air vent and the air quantity.

Temperature-controlled air comes out of the rear footwell air vent.

REAR FOOTWELL AIR VENT LOCATION - GF83.10-P-2110-02GH

The rear footwell air vent (three vents) is integrated in the rear footwell air duct (5) and is beneath the center

REAR NOZZLE FUNCTION - GF83.10-P-2111-01GI

Function

The air flow direction of the rear nozzle (1) can be directed up, down, left or right as required using two
individually-adjustable slatted shutters (2, 3).

The air distribution between the rear compartment and the rear footwell can be adjusted by operating the rear
compartment air distribution switch (

) and the rear air distribution flap actuator motor (M2/21) that it

actuates.

The quantity of air can be adjusted by operating the blower button (

) and the rear blower motor (M2/1) that

it actuates.

Operating the Auto button (

) causes the AAC push-button control module (N22) to regulate the air

distribution and air quantity.

RECIRCULATING AIR SWITCH FUNCTION - GF83.10-P-2117-01GH

Function

Pressing the recirculating air switch (

) actuates the fresh air/recirculating air flap actuator motor (M39),

which opens the recirculating air flap using a mechanical operating mechanism and simultaneously closes the
fresh air supply.

If the manual recirculating air system is active the diode illuminates in the recirculating air switch (

).

RECIRCULATING AIR SWITCH LOCATION - GF83.10-P-2117-02GH

The recirculating air switch (

) is in the heater control unit (S98).
