at the top or bottom, respectively.

your individual preferences by adjusting the lat-
eral-support pads.
Press the front or rear end of the switch.
Backrest width decreases or increases accord-
ingly.
Head restraints
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Adjust the head restraint in such a way
that its center is at approx. ear level. Oth-
erwise, there is an increased risk of injury in the
event of an accident. Only remove a head
restraint if no one will be sitting on the seat in
question. Reinstall the head restraint before
transporting anyone on that seat. Otherwise,
the passenger will be without protection from
the head restraint.<
