Front seats
In addition to the redesigned seat cushions and back-
rests, the sides of the seats in particular have been
redeveloped with firm side bolsters for improved
comfort and functional lateral support.
The front seats are equipped with partially electric
seat adjustment as standard and have a manually
operated lumbar support. Fully electric seat adjust-
ment with memory function and a corresponding
pneumatic lumbar support are offered as special
equipment.
On the top of the backrests are the NECK-PRO head
restraints with their new continuous inclination adjust-
ment.
As an option, the front seats can also be ordered as
multicontour seats or active multicontour seats.

Multicontour seat, code (409)
The driver and front passenger seats can be ordered
as multicontour seat as special equipment.
The multicontour seat offers the ability to further
improve comfort by adjusting the length of the seat
cushion and the contour of the backrest individually
and steplessly to fit the body shape of the driver and
front passenger.
This seat adjustment for the driver and front
passenger is accomplished by inflating and deflating
air chambers that are integrated in the front of the
seat cushion and the surface of the backrest. The seat
cushion contains an air chamber for the thigh area.
More air chambers are located in each side and on the
surface of the backrest. The controls are installed on
the side of the seat cushion between the side bolsters
and the center console.
Active multicontour seat, code (432)
The active multicontour seat is a development of the
multicontour seat. As well as seat contour adjustment,
the active multicontour seat contains a massage func-
tion and automatic adjustment of the lateral support
of the backrest to suit the current driving situation.
When the vehicle dynamics function is activated, the
air pressure in the side bolsters of the backrest is
changed electropneumatically according to the
steering angle, the lateral acceleration and the speed
of the vehicle. When the active multicontour seat
vehicle dynamics function is switched off, the pres-
sure in both chambers in the backrest returns to the
pressure that existed before the function was acti-
vated.
