Note | t
| The codes “Germany”, “Europe”, “Canada” or “Great Britain” are used for other vehicle systems. There are no differences between them at present with respect to the air conditioner. With this code, the “air recirculation” function is erased on switching off the ignition and the temperature display in the dash panel insert and the operating and display unit, Climatronic control unit -J255- is switched to ° C (centigrade). The temperature display unit in the operating and display unit, Climatronic control unit -J255- can be altered → Chapter. |
| t
| If the code for “Japan” is transmitted by the control unit in dash panel insert -J285-, the “air recirculation” function remains stored when the ignition is switched off and, after switching on the ignition with this key, the operating and display unit, Climatronic control unit -J255- switches to recirculated-air mode again. |
| t
| If the code for “USA” is transmitted by the control unit in dash panel insert -J285-, air conditioner regulation is set to somewhat “cooler” and the temperature display is switched to ° F (Fahrenheit). The temperature display unit in the operating and display unit, Climatronic control unit -J255- can be altered → Chapter. |
| t
| If the code for “Australia” or “Saudi Arabia” is transmitted by the control unit in dash panel insert -J285-, air conditioner regulation is set to somewhat “cooler”. |
| t
| If the code for a right-hand drive vehicle is transmitted, the control unit in dash panel insert -J285- alters the actuation of the control motors (different connector assignment at control motors). The operating and display unit, Climatronic control unit -J255- no longer detects the absence of the air flow flap control motor -V71- as being a fault and the seat occupied sensor for the driver's and front passenger's heated seat cushions is interchanged. |
| t
| The heating of the coolant after a cold start calculated by the operating and display unit, Climatronic control unit -J255- differs depending on engine version. |
| t
| Proceed as follows if the encoding of the operating and display unit, Climatronic control unit -J255- is to be switched for example to a different country version (e.g. to USA characteristic curve, regulation somewhat cooler in summer) without changing the code in the control unit in dash panel insert -J285-: |
| –
| Alter the encoding in the control unit in dash panel insert -J285- to the desired code (e.g. for USA). |
| –
| Perform basic setting of operating and display unit, Climatronic control unit -J255-. |
| –
| Alter the encoding in the control unit in dash panel insert -J285- back to the original code. |
