Important safety notes
G
WARNING
Only for the United Kingdom: if the vehicle
has been locked with the key or with KEY-
LESS-GO, the double lock function is activa-
ted 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. 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. The doors can then be
opened from the inside after the vehicle has
been locked from the outside.
G
WARNING
If children are left unsupervised in the vehicle,
they could:
R open a door from inside the vehicle at any
time, even if it has been locked
R start the vehicle using akey which has been
left in the vehicle
R release the parking brake 88

Important safety notes
G
WARNING
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could adjust the seats and
become trapped. G
WARNING
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted
from the road and traffic conditions and you
could lose control of the vehicle as a result of
the seat moving. This could cause an acci-
dent. G
WARNING
If you adjust the seat height carelessly, you or
others could be trapped and thereby injured.
Children in particular could unintentionally
press the buttons to electrically adjust the
seats and become trapped.
Take care that:
R while moving the seats, your hands do not
get under the lever assembly of the seat
adjustment system.
R children in the vehicle do not slide their
hands under the levers. G
WARNING
Make sure that nobody can become trapped
when adjusting the seats.
Observe the notes on airbags.
Secure children as recommended; see the
"Children in the vehicle" section. G
WARNING
Make sure that the back of your head is sup-
ported at eye level by the central area of the head restraint. If your head is not supported
correctly by the head restraint, you could suf-
fer a severe neck injury in the event of an
accident. Never drive if the head restraints are
not engaged and set correctly.
G
WARNING
As eat belt can only offer its intended degree
of protection when the backrest is almost ver-
tical and the occupant is sitting upright. Avoid
seat positions that do not allow the seat belt
to be routed correctly. Adjust the backrest so
that it is as upright as possible. Never travel
with the backrest reclined too far backwards.
You could otherwise be seriously or even
fatally injured in the event of an accident or
sudden braking.
! To avoid damage to the seats and the seat
heating, observe the following information:
R do not spill any liquids on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
