BMW Active Seat

Safety belt tensioner
DSP sound system
*
This causes a movement of the spinal 
column which is barely detectable, to-
gether with an improvement in the flow 
of blood to the intervertebral disks and 
the muscle structure in the area of the 
spinal column.
The passengers do not suffer as much 
from muscle tension, back pain in the 
lumbar region or symptoms of fatigue. 
As a result, the Active Seat represents a 
significant contribution to driving com-
fort and driving safety.
The safety belt tensioner responds to 
collisions by tightening the belts to en-
sure that occupants remain firmly posi-
tioned in their seats. A gas-pressure 
system retracts the buckle assembly to 
tension the shoulder and lap belts 
within fractions of a second. This re-
duces the tendency to slide under the 
lap belt.

The DSP Professional premium sound 
system features a special amplifier 
combined with Digital Sound Process-
ing (DSP) and integrated speakers to 
surround you with crisp, true-to-life 
sound reproduction. 
The speaker system's subwoofers, 
woofers, midrange speakers and tweet-
ers furnish you with an impressively full-
bodied listening experience. The indi-
vidual components are oriented so as 
to produce the aural sensation that you 
would experience facing the stage in a 
concert hall. The system also automati-
cally adjusts the bass and treble set-
tings to compensate for changes in vol-
ume and vehicle speed.
