Adjusting the seatback width increases or decreases lateral support.
Shoulder support
The adjustable upper seatback supports the occupant's back at shoulder level. This relieves tension in the shoulder muscles.
The shoulder support also adjusts the distance between the head and the head restraint.
Lumbar support

The seatback contour can be changed to provide optimum support for the natural curve (lordosis) of the lower spine.
Support for the upper pelvis and spine allows you to adopt an upright and relaxed posture.
