The movement sensor triggers the alarm when movement is detected in the passenger compartment. A valuable addition to the basic equipment.
The level sensor triggers the alarm if the position of the car changes, for example in the event of attempted wheel theft or an attempt to tow the car away.
Using the electric switch, it is possible to turn off alarm sensors as well as the BLL-function. Used to avoid accidental triggering of the alarm, e.g., if the dog is left in the car or when travelling on a ferry. (The button is standard on cars with BLL.)
