Switch For Reduced Alarm
The switch for reduced alarm is in the front lighting panel in the roof. The switch is only found in vehicles with deadlocks for central locking and/or an alarm system that consists of sensors (i. e. level above perimeter guard).
The switch is used to temporarily deactivate the vehicle tilt sensor and Mass movement sensor module (MMS) alternatively ultrasonic sensor module (IMS) functions. When the function is activated the doors are not deadlocked when the vehicle is locked. The function can only be activated when the ignition has been switched off and up to a minute after the ignition key has been taken out of the ignition switch. If a longer time has passed the ignition must be turned to position II and back to 0 before the function can be activated.
The switch has an integrated LED to indicate when the function is activated. A message is displayed in the display in the driver information module (DIM).
