Introduction to the topic  
In the following situations it is recommended to  
deactivate the passenger compartment monitoring  
and the anti-tow system:  
The tailgate is unlocked and locked together with  
the doors.  
— When people or animals remain inside the  
On vehicles with the "Keyless Access" keyless entry  
and start system, the tailgate unlocks automatically  
when opened ÿ p. 78.  
— When the vehicle has to be loaded onto another  
means of transport.  
If individual door opening or opening of one side of  
the vehicle is activated in the opening and closing  
settings of the infotainment system, the button on  
the vehicle key must be pressed twice to unlock the  
— When transporting the vehicle.  
— When the vehicle has to be towed with a  
suspended axle.  
— When the vehicle is to be parked in a two-  
storey garage space.  
On vehicles with the "Keyless Access" system, the  
sensor surface on the inside of the driver's or front  
passenger's door handle must be actuated twice .  
— When the vehicle has to be left in a car wash.  
Risk of false alarms from interior monitoring  
The interior monitor will only work correctly if the  
vehicle is completely closed.  
Observe the legal provisions. A false alarm may  
occur in the following situations:  
Unlocking, opening or closing the tailgate  
improperly or without paying due attention can  
cause accidents and serious injuries.  
· Open or close the tailgate only when there is no  
one in the area of its travel.  
— If any window or the glass roof is partially or  
completely open.  
— If light objects are left in the vehicle, e.g. eg,  
loose or hanging papers in the interior mirror.  
· After closing the tailgate, make sure that it has  
been closed correctly. The tailgate should be  
flush with the adjoining parts of the bodywork.  
— If the vibrate function of a mobile phone that has  
been left inside the vehicle is activated.  
· Always keep the tailgate closed while driving.  
It is not possible to permanently deactivate  
the interior monitor and the anti-tow system.  
· Never open the tailgate with cargo, such as  
bicycles, attached to it. The gate could close  
on its own due to the additional weight. If  
necessary, secure the tailgate or remove the  
load beforehand.  
If, when activating the anti-theft alarm, a  
door or the boot lid is still open, only the  
alarm will be activated. The anti-tow system will  
only activate once all the doors and the tailgate  
have been closed.  
· Close and lock the tailgate and all doors when  
the vehicle is not in use. When doing so, make  
sure that no one remains in the vehicle.  
Depending on the equipment, when the  
interior monitor and anti-tow system are  
switched off, the "safe" security system is also  
deactivated ÿ p. 84.  
· Always keep a close eye on children when they  
play in or next to the vehicle, especially if the  
tailgate is open. Children could get into the  
trunk, close the tailgate and be locked in.  
Depending on the season of the year, a closed  
vehicle can reach very high or very low  
temperatures that can cause very serious  
injuries and illnesses or even death, especially  
to small children.
