& 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.
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.
To adjust the seat fore-and-aft position:
#
lift lever 1 and slide the seat into the
desired position.
Make sure that the seat is engaged.
#
To adjust the seat height: push or pull lever
#
2 until the desired position has been
reached.
