Extended user-programming


The ACC control module can also be programmed by the user so that certain automatic control functions can be changed. These selections are stored and used by the control module until the program is cancelled. Programming and cancelling the program are both selected by pressing ECON, air recirculation or rear window heating for longer than 1.2 seconds. In all three cases, the selection will be confirmed by the selected function symbol flashing 4 times and a message being displayed on SID for 5 seconds. The various extended functions are explained below:

ECON

The function is automatically selected when the outside temperature is below 10°C at the same time as the solar intensity is lower than 351 W/m 2 and returns when the temperature exceeds 13°C or if the solar intensity is higher than 351 W/m 2 .

Note

The ACC control module does not accept increased temperatures unless the vehicle speed exceeds 30 km/h.


Adjustment

The ACC unit can be adjusted with the diagnostics tool so that ECON is selected at other temperatures.

Air recirculation

This function is selected automatically when the vehicle speed is below 10 km/h and disengages when the vehicle speed exceeds 30 km/h.

Observe that fresh air is automatically selected if the temperature is below +7 °C. Returns to recirculation when the temperature exceeds +10°C.

Adjustment

The ACC unit can be adjusted with the diagnostics tool to automatically select air recirculation at other speeds.

Electrically heated rear window and door mirrors

The control module requests that the electrically heated rear window is engaged within 5 seconds after the engine has been started if the outside temperature is below 5°C and at the same time the cabin temperature is below 10°C. The engagement time depends on the outside temperature.

At +5°C the time is 5 minutes and at lower temperatures the time is increased to max 10 minutes when the outside temperature is lower than -10°C.

Note

Experience shows that half the ACC control modules returned during the warranty period have not been defective but user-programmed. Therefore, it is important that this function is explained to the customer.
