Although numerous factors combine to
impose inherent limitations on the
of blood to the vertebral discs and the
muscles in the area of the spinal
column. Vehicle occupants can experi-
ence less muscle cramping, back pain
in the spine's lumbar region and
fatigue. The active seat thus provides a
significant contribution to your driving
comfort and safety.

be employed to minimize their effects:
The "Radio Data System" (RDS) makes
sure that, for broadcast stations
sending on several frequencies, the

several FM antennas integrated within
the rear window. An integral processor
automatically selects the antenna with
the best FM reception quality at any
given time. The selection of the antenna
takes place within milliseconds, and
is therefore not noticed by the radio
listener.

BMW's seats, designed to ensure less
fatigue during extended trips while
sitting with little movement. The seat is
no longer a passive element between
the road, the running gear and the
passenger. Instead, it creates minor
and imperceptible shifts in your weight

Fluid cushions are located below the
surface of the seat in the seat's uphol-

circulated slowly back and forth
between the two cushions by means of
a pump. This causes a movement of the
spinal column which is virtually imper-
