WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle. If the vehicle has been locked from the outside,

ard. It is then not possible to open the doors
from inside the vehicle. You can deactivate the
double lock function by deactivating the interior
motion sensor (see the separate multimedia
system operating instructions). The doors can
then be opened from the inside after the vehicle
has been locked from the outside. The anti-theft alarm system is triggered if the door is opened
