לא סתם שאלתי, להלן קטע מתוך מדריך טכני של PSA על המערכת:
The function of the external temperature sensor is to provide information via the BSI
on the external conditions.
If the external temperature is under -10°C or over 30°C and there is a request for air
conditioning, engine Stop is forbidden.
If the temperature different is too high between the interior setting requested by the
occupants and the calculated interior temperature, in the engine Stop phase, the
engine may re-start rapidly.
But the difference between the setting and the actual temperature also depends on
the external temperature.
