& WARNING Risk of accident due to
adjusting vehicle settings while the vehi‐
cle is in motion
You could lose control of the vehicle in the
following situations in particular:
If you adjust the driver's seat, the head
R
restraints, the steering wheel or the mir‐
ror while the vehicle is in motion.
If you fasten your seat belt while the vehi‐
R
cle is in motion.
Before starting the engine: adjust the
#
driver's seat, the head restraints, the
steering wheel and the mirror and fas‐
ten your seat belt.
& WARNING Risk of becoming trapped if
the seat height is adjusted carelessly
If you adjust the seat height carelessly, you
or other vehicle occupants could be trapped
and thereby injured.
Children in particular could accidentally
press the electrical seat adjustment buttons
and become trapped.
While moving the seats, make sure that
#
hands or other body parts do not get
under the lever assembly of the seat
adjustment system.
& WARNING Risk of injury due to head
restraints not being installed or being
adjusted incorrectly
If head restraints have not been installed or
have not been adjusted correctly, 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
#
installed.
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.
Seats and stowing
Do not interchange the head restraints of the
front and rear seats. Otherwise, you will not be
able to 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.
& WARNING Risk of injury or death due to
an incorrect seat position
The seat belt does not offer the intended
level of protection if you have not moved the
seat backrest to an almost vertical position.
You could slip beneath the seat belt and
injure yourself.
Adjust the seat properly before com‐
#
mencing your journey.
Always ensure that the seat backrest is
#
in an almost vertical position and that
the shoulder belt is routed across the
center of your shoulder.
