Airbags; Adaptive Transmission Control (Atc) - BMW Z3 COUPE 2002 Owner's Manual

ATC
*
164n
For vehicles with automatic transmis-
sion, Adaptive Transmission Control
(ATC) performs the optimum gear selec-
tion based on a number of factors. This
system reacts to your individual driving
style and the current driving conditions.
The ATC recognizes your individual
driving style from the positions and
movements of the accelerator pedal,
delays during braking, and the vehicle's
lateral acceleration when cornering.
ATC makes the appropriate selection
from different shift characteristics
which range from comfort-oriented to
performance-oriented.
In order to take driving conditions into
account, ATC registers corners and
both uphill and downhill gradients. For
example, if you maintain speed through
a curve, the transmission does not
upshift.
On uphill gradients, it shifts only when
the engine speed increases in order to
make more efficient use of power
reserves. On downhill gradients ATC
downshifts when the speed of the vehi-
cles increases causing the driver to
step on the brakes.

Airbags

Deceleration sensors continuously
monitor the physical forces acting upon
the vehicle. In the event of a severe
frontal impact, the gas generators of
the driver and passenger-side front
airbags are ignited simultaneously.
However, the passenger-side airbag is
only triggered if an additional sensor
has recognized that the passenger seat
is occupied.
If it is necessary during a side impact, a
side airbag will be triggered on the side
where the collision occurs.
