Function description for dynamic multicontour seat, general
The dynamic multicontour seat combines the advantages of a comfortable multicontour seat with those of a sport seat. Here, a base pressure in the lateral support cushions automatically adjusts the seat's lateral support. The dynamics function enhances the lateral support when cornering. For this, the lateral support is improved during cornering by means of an automatic pressure increase of the lateral support cushions (side bolsters) on the outside of the curve. Intensity can be adjusted in two stages. This essentially happens as a function of the current vehicle speed and the lateral acceleration.

To prevent any tension in the back during long journeys, the multicontour seat is equipped with a massage (pulse mode) function. As long as the massage function is active, the contour of the 7-layer massage insert is sequentially altered by inflating, maintaining and relieving the pressure.

Intensity can be adjusted in two stages. The pulsation takes place in pressure jumps in the upward or downward direction. Dwell time can be adjusted via diagnosis.

Adherence to the set pressure values as well as the specified pressures of the individual cushion areas is continuously being regulated.

The various air cushions can be adjusted via the dynamic multicontour seat button group.

When the pulse function is switched on (massage function), the following are actuated automatically:
- 7 rows of massage air cushions located one above the other

The dynamic multicontour seat system is available in a version for the left seat and a version for the right seat.

The air supply, required for inflating the air cushions, is supplied by the dynamic multicontour seat pneumatic pump. The adjusted contours can be saved.

Priorities
When several buttons are actuated at the same time, only the adjustment motion with the highest priority is executed.
Priority 1: Lateral backrest support
Priority 2: Lumbar support
Priority 3: Seat cushion (except code (494) USA version, passenger side)
Priority 4: Dynamic multicontour seat
Priority 5: Massage function (pulses)

PRE-SAFE
In critical situations, the air cushions in the side areas are inflated before the imminent accident in order to provide a favorable seat position and to secure the occupants in their position. For more detailed information refer to the PRE-SAFE system description.
