You can change the width of the backrest to suit
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.
Longitudinal adjustment from outside/
behind*
To move the front seats forward or backward
from outside or from one of the rear seats: with
the door open, press the front end 1 or rear end

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
