If interior monitoring is activated, a visual alarm and an audible alarm are triggered when movement is detected in the interior. This is the case, for example, when someone enters the interior.
Activation:
- Make sure that
- the side windows are closed
- the panoramic sliding roof is closed
This will prevent the alarm from being triggered unintentionally.
- Lock the vehicle with the key.
Interior monitoring is activated approximately 30 seconds later.
Deactivation:
- Unlock the vehicle with the key.
Interior monitoring is deactivated automatically.

Deactivation:
- Remove the key from the ignition switch.
- Press button 1.
Indicator lamp 2 flashes briefly.
- Lock the vehicle with the key.
Interior monitoring is deactivated.
Interior monitoring remains deactivated until
- the vehicle is unlocked again.
- a door has been opened and then closed
- the vehicle has been locked again
To prevent the alarm from being triggered unintentionally, deactivate interior monitoring before locking the vehicle when
- people or animals must remain inside
- the side windows must remain open
- the panoramic sliding roof must remain open
