NOTE
If the ultrasonic sensors are set too sensitively, the alarm may be
triggered by passing vehicles. For this reason set the sensitivity carefully,
and not too high.
To find the right setting, proceed as follows:
➤ Deactivate the alarm system (see chapter "Deactivating MagicSafe" on page 44).
➤ Open the front side window about 20 cm.
➤ Activate the alarm system with the doors, bonnet and boot closed.
➤ Move an object into the vehicle interior from outside:
– If an alarm is triggered before you move the object into the vehicle, reduce
the sensitivity.
– If no alarm is triggered, increase the sensitivity.

NOTE for convertibles and vehicles with folding tops
For vehicles with cloth or plastic roofs, the sensitivity of the ultrasonic
sensors must be reduced significantly or be disabled altogether.
➤ Knock on the closed cover to check whether MagicSafe triggers the alarm when
the cover moves.
