Safety Warning

Central Locking Button
A new function for the central locking system is the ability to activate central locking from the trunk.
The central locking button is located on the underside of the trunk. Whether or not the button is present depends on which equipment is installed on the vehicle.
Pressing the central locking button locks and centrally locks all vehicle doors.
The button status is evaluated by the Car Access System. If the vehicle is in sleep mode, it must first be woken up.
The Car Access System recognizes that the central locking button has been pressed and locks and centrally locks the car as appropriate.
| Option | Central locking button | |
|---|---|---|
| Comfort Access (CA) | Central locking button | |
| Automatic Trunk Actuation (HKL) | Button for HKL actuation is located next to central locking button | |
