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withdrawn from the ignition switch, then 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.

functions:  

  

  

 Central locking using SAFE system 

(lock once) LED activation then 50ms 
on and 950ms off, when the safe 
condition is obtained 

  

  

 Central locking not using SAFE system 

(lock twice) LED goes out.
