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 . The doors can
then be opened from the inside after the vehi- cle has been locked from the outside. The
anti-theft alarm system is triggered if the door
is opened from the inside. Switch off the
alarm (Y page 85).

cle, they may be able to set the vehicle in
motion if, for example, they:

R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If you attach heavy or large objects to the key, the key could be unintentionally turned in the
ignition lock. This could cause the engine to
be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to the
key. Remove any bulky keyrings before insert-
ing the key into the ignition lock.

fields. Otherwise, the remote control func-
tion could be affected.

Start/Stop button General notes
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehi-
cle. This occurs, for example, when starting
the engine.

the ignition lock
R the key must be in the vehicle
R the vehicle must not be locked with the key

Start/Stop button, the engine starts immedi-
ately.
