Airbags  
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.  
For vehicles with automatic transmis-  
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.  
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.  
If it is necessary during a side impact, a  
side airbag will be triggered on the side  
where the collision occurs.
