Risk of injury
Only for the United Kingdom: if the vehicle
has been locked with the key, the double lock
function is activated as standard. It is then not
possible to open the doors from inside the
vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people requiring special assistance, if
the vehicle has been locked with the key. As
a result, they may not be able to free them-
selves in the event of an emergency. They
could be seriously or even fatally injured by
prolonged exposure to extremely high or low
temperatures, for example. In this case, res-
cuing people from outside the vehicle is diffi-
cult.
Deactivate the interior motion sensor before
you lock the vehicle with the key. The doors
can then be opened from the inside after the
vehicle has been locked from the outside with
the key. If the vehicle has been locked with KEYLESS-
GO, the doors can be opened from inside the
vehicle. G

they could:
R open a door from inside the vehicle at any
time, even if it has been locked

left in the vehicle

They could thereby endanger themselves and
others. Never leave children unsupervised in
