Automatic transmission
Introduction
Applies to: vehicles wit h automatic transmiss ions
The automatic transmission is controlled elec-
tronically . Upshifting and downshifting occur au-
tomatically.
When a
moderate driving style is used, the
transm ission selects the most economica l driving
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
In the "S" se lector lever posit ion, the transm is-
sion switches to a sporty mode after a kick-down
or when the driver uses a
sporty driving style
characterized by quick accelerator pedal move-
ments, heavy acceleration, frequent changes in
speed and traveling at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) ¢ page 88, Manual
shifting (tiptronic mode).
The S tronic is a dual-clutch transmission. Power
is transferred using two clutches that work inde-
pendently from one another. They replace the
torque converter used in conventional automatic .,.
