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.
Always drive with the head restraints fitted.
Ensure that the centre of the head restraints
support the back of each vehicle occupant's
head at eye level before driving off.
Do not interchange the head restraints of the
front and rear seats. Otherwise, you cannot
adjust the height and angle of the head
restraints correctly.
Adjust the head restraint fore-and-aft position
so that it is as close as possible to the back of
your head. G
WARNING
If the driver's seat is not correctly engaged, it could unexpectedly move while driving. This
could cause you to lose control of the vehicle. There is a risk of an accident.
Always ensure that the driver's seat is
engaged before starting the vehicle. G
WARNING
You could lose control of the vehicle while
driving if you:
R adjust the driver's seat, steering wheel or
mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirrors and fasten your seat
belt before starting the engine. G
WARNING
If you adjust the seat height carelessly, you or other vehicle occupants could be trapped andthereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the lever assembly of the seat adjustment sys-
tem.
G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder.
! 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 heat-
ing should also not be used to dry the seats.
R clean the seat covers as recommended;
see "Interior care".
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 passen-
gers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating materi-
als, e.g. blankets, coats, bags, seat covers,
child seats or booster seats.
! Make sure that there are no objects in the
footwell under or behind the seats when mov- ing the seats back. There is a risk that the
seats and/or the objects could be damaged.
