1Lowest temperature received via convenience data bus system since activation
–  Display zone not used with all auxiliary heater versions
t  Display = -XX .... +XXX °C
–  The ambient temperatures transmitted by the control unit in dash panel insert -J285- and the operating and display unit, Climatronic control unit -J255- of the air conditioner/heater are compared and the lowest value is displayed.
–  Allowance is only made for the coolant temperature transmitted by the control unit in dash panel insert -J285- if a valid value is supplied (refer to display zone “3” in display group “009”)
2Current engine speed transmitted by control unit in dash panel insert -J285- via convenience data bus system
t  Display = XXXX rpm
–  The control unit in dash panel insert -J285- transmits the engine speed by way of the convenience data bus system to the other control units.
3Remaining auxiliary heater operating time for this heating period in seconds transmitted by control unit in dash panel insert -J285- via convenience data bus system
t  Display = 0
–  Auxiliary heater switched off
t  Display = 1 ..... 3600
–  Deactivation of auxiliary heater by control unit in dash panel insert -J285- in so many seconds
–  The dash panel insert calculates the remaining operating time by way of the operating time set in the control unit in dash panel insert -J285- and transmits this by way of the convenience data bus system to the auxiliary heater control unit -J364-.
4Display zone not used

  Note
t  The auxiliary heater operating time is calculated on the basis of the setting in the driver information system (DIS) by the control unit in dash panel insert -J285-. The adjustable ON time (currently 15....60 min (900....3600 sec.)) is transmitted by way of the convenience data bus system to the auxiliary heater control unit -J364- together with the activation signal.
t  The auxiliary heater is switched on and off by the control unit in dash panel insert -J285-. If the control unit in dash panel insert -J285- transmits an activation signal for more than 3600 sec., the auxiliary heater control unit -J364- switches off the auxiliary heater on completion of the safety margin (160 to 400 sec. depending on version of auxiliary heater control unit -J364-).
t  The maximum operating time entered in the auxiliary heater control unit -J364- and thus permissible of 3870 sec. at present may, depending on version of auxiliary heater control unit -J364-, also be slightly longer or shorter.
