Important safety notes
United Kingdom only:
G 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 out-
side, the double lock function is activated as
standard. It is then not possible to open the
doors from inside the vehicle. You can deac-
tivate the double lock function by deactivat-
ing the interior motion sensor (
Y
page 90).
The doors can then be opened from the inside
after the vehicle has been locked from the
outside. The anti-theft alarm system is trig-
gered if the door is opened from the inside.
Switch off the alarm (
Y
page 89).
