Comfort Seats (standard on E38 750iL, other models if equipped)
This option provides additional back support in the
shoulder area. An additional adjustment in the upper
backrest allows forward “contour” that is controlled by
a rocker switch in the side panel.
When the ignition is on or off, the two way rocker switch
can be pushed until the desired setting is achieved (for-
ward/backward tilt). The motor drive operates the same
as the seat motors.
The shoulder support adjustment is also stored in
memory for recall.
Active Seat (E38 - if equipped)
Purpose of the System
Actively changing the surface of the seat helps to prevent muscle tension and fatigue par-
ticularly on long trips or sitting in one position for a long period of time. The seat causes
weight transfers which are slight and imperceptible enhancing driving comfort. The basic
seating position is not changed by this.
In the seat’s upholstery beneath the surface of the seat is a cushion of fluid on the left and
right. The fluid is slowly circulated back and forth between the cushions by a pump.
