WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
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 mirror 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
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level. 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 seat belt is routed
across the center of your shoulder.
! To prevent damage to the seats and the seat
heating, observe the following notes:
R Do not spill liquids onto the seats. Dry the
seats as soon as possible if liquid does get
spilled on the seats.
R If the seat covers are damp or wet, do not
switch on the seat heating. Also, do not use
the seat heating to dry the seats.
R Clean the seat covers as recommended;
see keyword "Care".
R Do not transport heavy loads on the seats.
Do not place pointed objects on the seat
cushions such as knives, nails or tools.
Where possible, use the seats only for car-
rying passengers.
R When operating the seat heating, do not
cover the seats with insulating materials,
e.g. blankets, coats, bags, protective cov-
ers, 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.
