On vehicles with an automatic trans-

mission, the ATC (Adaptive Transmis-

sion Control) uses a number of factors

to calculate the gear which provides the

maximum efficiency. In this process, it

considers your individual 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. Based on different shift

characteristics – from comfort-oriented

to performance-oriented – ATC will se-

lect the appropriate gear.

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 in-

creases 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.
