Lumbar support

The curvature of the seat backrest can be ad‐
justed in such a way that it supports the lumbar
region of the spine. The lower back and the
spine are supported for upright posture.
▷ Press the front/rear section of
the switch.
The curvature is increased/
decreased.
▷ Press the upper/lower sec‐
tion of the switch.
The curvature is shifted up/
down.
Backrest width
Change the width of the backrest using the side
wings to adjust the lateral support.
To make it easier to enter and exit the vehicle,
the backrest width temporarily opens fully.
Shoulder support
Also supports the back in the shoulder area:
▷ Results in a relaxed seating position.
▷ Reduces strain on the shoulder muscles.
