| Display zone | Significance | Explanatory notes |
| 1 | Actual feedback value of defroster flap control motor potentiometer -G135- (in defroster flap control motor -V107-) | | l
| Display value greater than “9” and less than “251” |
| l
| Maximum permissible deviation “3” units from specified feedback value (only in range greater than “70” but less than “190”) |
|
| 2 | Specified feedback value for defroster flap control motor potentiometer -G135- (calculated by operating and display unit, Climatronic control unit -J255-) | | l
| Display range “10 ... 155 ( ...165)” |
| –
| The “Upper stop” is not reached in control mode; the flap is not moved as far as the stop even in defrost mode. |
|
| 3 | Value determined during “Basic setting” and stored in the operating and display unit, Climatronic control unit -J255- for the defroster flap control motor potentiometer -G135- with control motor set to “Lower stop” (defroster flap closed) | | l
| Display value greater than “9” and less than “71” |
|
| 4 | Value determined during “Basic setting” and stored in the operating and display unit, Climatronic control unit -J255- for the defroster flap control motor potentiometer -G135- with control motor set to “Upper stop” (defroster flap open) | | l
| Display value greater than “189” and less than “246” |
