The STC control module continuously sends out bus information on the position of the soft top, i.e. raised, in motion or lowered.
Information is used by ACC which assumes the following condition when the soft top is unlocked from the windscreen frame.
-
AUTO goes out.
-
The temperature value is substituted with the position of the air-mixing damper in steps of 1 to 10, where 10 is max. heat.
-
The air-mixing damper will assume the position 0-10 closest to the position it had when the soft top was raised.
-
The air recirculation flap will assume the position for fresh air.
-
A/C is disengaged.
-
The electrically heated rear window/door mirrors are turned off.
When the soft top is raised, the ACC system resumes the settings it had before the soft top was lowered, provided that the ignition has not been turned off
during that time. If the ignition has been turned off when the soft top was down, the ACC will assume the AUTO position when the soft top is closed.
All manual selections except electrically heated rear window/door mirrors and recirculation can be performed while the soft top is down.
