When the boot is opened the light in the luggage compartment comes on and goes out when the boot is closed.The light inside the glove compartment comes on when it is opened and goes out when it is closed.The lights in the sun visors are operated by lowering the actual visors. The Body Computer continuously acquires the battery voltage signal to compare it with its own reference level; if the battery voltage level is below the minimum value, it intervenes sending a signal to disable a series of loads: these include the glove compartment light and the sun visor lights; the deactivation function, for a timed period of 15 minutes (reset and reactivated at each door opening or door release command using the remote control) is only activated with the ignition switched OFF.
