Anti-theft alarm
Depending on the vehicle equipment level, the vehicle may have an anti-theft alarm.
The anti-theft alarm is activated automatically when the vehicle is locked using the vehicle key.
The anti-theft alarm outputs acoustic and visual warning signals for up to five minutes.
When does the system trigger an alarm?
If a door is opened.
If the bonnet is opened.
If the boot lid is opened.
If the ignition is switched on with a valid vehicle key. (The alarm may sound briefly.)
If the 12-volt vehicle battery is disconnected.
If there is movement inside the vehicle (in vehicles with interior monitoring) Interior monitoring

If movements are detected in the vehicle interior when the vehicle is locked, the interior monitoring
system will trigger an alarm Fig.
The anti-tow alarm will be triggered if the vehicle is lifted.
Switching on the interior monitoring system and anti-tow alarm
Close the stowage compartments in the roof console so that the sensors can function.
Close the windows, glass roof, doors and boot lid
Press the locking button once.
The interior monitoring system and anti-tow alarm are activated.
Temporarily switching off the interior monitoring system and anti-tow alarm
The interior monitoring and the anti-tow alarm can be switched off temporarily in the Vehicle
settings menu in the Infotainment system Infotainment system controls and displays
To avoid false alarms, deactivate interior monitoring and the anti-tow alarm in the following
situations:
If any people or animals are to remain inside the vehicle.
If the vehicle is to be loaded onto another vehicle, transported or towed away.
If the vehicle is to be parked in a car wash or a two-storey garage.
If one or more windows or the glass roof are fully or partly open.

nobody obstructs the path of the window, especially if a window is being closed when
the roll-back function is not active.
The roll-back function does not prevent fingers or other body parts from being pressed against the
window frame and being injured.

The roll-back function is also activated if the windows are closed using the vehicle key for
convenience closing.
Troubleshooting
One-touch opening and closing does not work
One-touch opening and closing is deactivated if the 12-volt vehicle battery has been disconnected or
discharged while the windows were not fully closed. The function must then be reset:
Switch on the ignition.
Close all windows and doors.
Pull up the button for the respective window and hold it in this position for several seconds.
Release the button, then pull it up again and hold it in this position. The one-touch function is now
ready for operation again.
The one-touch function can be restored for individual windows or for several windows at the same
time.
Closing windows without roll-back function
Attempt to close the window again within a few seconds by holding the button. The roll-back
function will be deactivated for a small part of the path of the closing window.
If the closing procedure takes longer than several seconds, the roll-back function will be reactivated.
If it is still stiff or obstructed, the window will stop and open again automatically.
Please go to a qualified workshop if the window still cannot be closed.

The lights go out when the vehicle is locked or after a delay of a few minutes when the vehicle key is
removed from the ignition lock. This prevents the 12-volt vehicle battery from discharging.
