For vehicles with automatic transmis-
sion
*, Adaptive Transmission Control
(ATC) makes the optimum gear selec-
tion based on a number of factors. In
this process, it considers your individ-
ual driving style as well as current
driving conditions.
ATC recognizes your personal driving
style from the positions and movements
of the accelerator pedal, deceleration
when braking, and lateral acceleration
through curves. ATC makes the appro-
priate selection based on various shift
characteristics, which range from com-
fort- to performance-oriented.

In order to include driving conditions in
its calculations, ATC registers curves
and both uphill and downhill gradients.
For example, if you maintain speed
through a curve, the transmission does
not shift up.
On uphill gradients, it shifts up only
when the engine speed increases in
order to make more efficient use of
power reserves. On downhill gradients,
ATC shifts down when the speed of the
vehicle increases and the driver must
apply the brakes.
