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 back‐
rest using the side wings to ad‐
just 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.

Active seat

Active adjustment of the seat cushion's con‐
tours reduces muscular tension and fatigue to
help prevent lower back pain.
