Risk of accident
Do not leave children unsupervised in the
vehicle. They could open a door from the in-
side – even if it is locked – and thereby en-
danger themselves and others.
i
You can open a door from the inside at any
time, even if it has been locked.
i
If you have previously locked the vehicle
from the outside with the remote control or the
KEYLESS GO key*, you cannot unlock it centrally
from the inside.
i
The vehicle can only be locked centrally if
the front-passenger door is closed.
