Centrally locking and unlocking the vehicle from the inside
You can centrally lock or unlock the vehicle from the inside.
The central locking/unlocking button does not lock or unlock the fuel filler flap.
You cannot unlock the vehicle
centrally
from the inside if the vehicle has been
locked with the SmartKey or KEYLESS-GO.
It is only possible to lock the
vehicle
centrally if the front-passenger door is
closed.

To unlock: press button

To lock: press button 2.
If the front-passenger door is closed, the vehicle locks.
You can open a front door from inside the
vehicle even if it has been locked. Only open
the door when the traffic situation permits.
If the vehicle has been locked with the central
locking button:
• and the SmartKey is set to its factory setting, the entire vehicle is
unlocked if a front door is opened from the inside
• and the SmartKey is set to an individual setting, only the front door that is
opened from inside the vehicle is unlocked.
If the vehicle has been locked centrally with the SmartKey or with KEYLESS-GO, it is not unlocked when the release button for the central locking is used.
