Interior Monitoring System, Description



Interior Monitoring System, Description

The interior monitoring system is an integral part of the anti-theft alarm system. The systems consists of two sensors into which the function of the rear reading lights are integrated. Setting the operating mode of the reading lights is performed on each of the sensors separately.

The interior sensors work on the ultrasonic wave principle. The alarm of the anti-theft alarm system will be triggered if movement is detected in the interior when the system is active.

The interior sensors can be switched off via a switch in the B pillar/door sill and via the adaptation (function 10, channel number 05). To do this the ignition key must be withdrawn from the ignition switch, then operate switch and lock the vehicle.

The sensors will be switched on again the next time the vehicle is unlocked. A waiting time of at least 30 seconds must be observed before commencing tests when the vehicle is locked.
