Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people in need of special assistance if
the vehicle has been locked with the key. As
ar esult, they may not be able to free them-
selves in the event of an emergency. As a
result, they could be seriously or even fatally
injured by prolonged exposure to extremely
high or low temperatures, for example. In this
case, rescuing people from outside the vehi-
cle is difficult.
Deactivat ethe 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.
G

from the road and traffic conditions and you
could lose control of the vehicle as aresult of
the seat moving. This could cause an acci-
dent. G

others could be trapped and thereby injured.
Children in particular could unintentionally
press the button stoelectrically adjust the
seats and become trapped.
