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 80).
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 79).
All countries: G

R open doors, thereby endangering other per-
sons or road users
R get out and be struck by oncoming traffic
R operate vehicle equipment and become
trapped, for example
In addition, the children could also set the
vehicle in motion, for example, if they:
R release the parking brake
R shift the automatic transmission out of park
position P or shift manual transmission into
neutral
R start the engine
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

become trapped, especially if they are unat-
tended. There is a risk of 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 the driver's seat is not engaged, it can move unexpectedly while the vehicle is in motion.
This could cause you to lose control of the
vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the engine. G

accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.

hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem. G

injury.
Make sure that no one has any part of their
body within the sweep of the seat when
adjusting it. G
WARNING
The head restraints cannot provide the inten-
ded protection unless they are fitted and
adjusted correctly. There is an increased risk of injury to the head and neck in the event of
an accident or sudden braking, for example.

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. The seats should only be occupied by
