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withdrawn from the ignition switch, then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.
