Reduced Alarm Function

The switch for reduced alarm is in the front lighting panel in the roof. The switch is used to temporarily deactivate the vehicle tilt sensor, mass movement sensor module (MMS) alternatively ultrasonic sensor module (IMS), deadlock function and glass breakage loop (only C30) when the vehicle is locked. The switch has an integrated LED to indicate when the function is activated.

The function is activated during a lock cycle - from when the button is pressed and the vehicle locked until the vehicle is unlocked again. When the ignition is turned to position II a message is displayed in the driver information module (DIM) that full protection is activated.

An example would be when a person or pet was being left in a locked vehicle. This may also be required if the car is being transported by ferry to prevent the vehicle tilt sensor triggering the alarm.
