Soft top and climate control system interaction.

The Body Computer BCM sends through a B-CAN network all information concerning the roof
position. All information is used by the climate control system node NCL to manage the climate inside
the compartment in the best way. If the soft top is open, the climate control system node manages the
fans to preserve their operation. In case of a high difference outside temperature and the temperature
set by the driver on the climate control system node, with open soft top, the interior temperature
sensor would detect always a rather high temperature; thus, the fan would work always at high speed
and risk following damage. Under these conditions, the climate control system node decreases the fan
speed. The climate control system compressor is operated by the driver even if the soft top is open.

Heated rear window-soft top interaction.

The heated rear window, like all non-convertible versions, is 20 minutes in total, with the following
difference:
Fiat 500 – 10 minutes engine off + 10 minutes engine on
Fiat 500 C – 15 minutes engine off + 5 minutes engine on
The defrosting function, meant as heated rear window and heated mirrors, if installed, can be enabled
only if the soft top is closed.
If the function is operating and the soft top is opened, it deactivates. In this case, when the roof is
closed, to restore the defrosting function press the button again.
