In the case of user programming by means of the buttons on the ACC panel it is only possible to select the opposite of what the ACC control module has selected in AUTO mode. Using the ISAT, the ACC control module can be user-programmed irrespective of the AUTO setting.
Important | ||
User programming carried out with the ISAT will be erased if deprogramming is done with the buttons on the ACC panel. |

The ISAT command "PARKING HEATER" enables changes to be made in the ACC's parking heater mode. When battery positive is applied to pin 3 of the ACC control module, it goes into parking heater mode (see Technical description, ACC for further information). Two different control processes can be chosen with the ISAT:
• |
100%% HEAT (basic setting) The control module sets the blended-air flap to the position for maximum heat.
|
• |
CONTROLLED HEAT The control module adjusts the blended-air flap according to the selected cabin temperature.

With the ISAT command "CABIN TEMPERATURE" it is possible to adjust how the cabin temperature sensor perceives the cabin temperature. If the cabin temperature sensor offset is increased, the temperature in the cabin will be increased by the corresponding number of degrees. The adjustment is done in steps of 0.1 ° C. Suitable adjustment intervals are ±0.3 ° C.
Important | ||
This adjustment should be done with good judgement. The adjustment is possible up to ± 3 ° . Too large an adjustment however leads to the ACC system reacting totally differently when starting from cold. Much stronger cold respective heat as well as greater ventilation effect can be achieved. |

With the ISAT command "TEMP SCALE" it is possible to change the temperature shown in the ACC unit's display between Celsius and Fahrenheit. This can also be done by pressing the buttons for temperature up and temperature down simultaneously for at least two seconds.

With the ISAT command "RECIRCULATION" the recirculation flap can be controlled by the speed of the car so that the ACC control module always closes the flap when the car's speed is 0 km/h.
Note | ||
Since the ABS control module counts all speeds below 3 km/h as stationary, the ACC control module will open and close the recirculation flap at about 3 km/h. |
