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 (

 ).
