Automatic
transmission
tiptronic
Introduction
The automatic transmission is controlled elec-
tronically. The transmission upshifts or down-
shifts automatically depend ing on which drive
program is selected. The power is transferred
by a torque converter .
When a
moderate driving style is used, the
transmission selects the most econom ical
driving mode. It will then change up early and
delay the downshifts to g ive better fuel econ-
omy.
The transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac-
celerator pedal movements, heavy accelera-
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) c:> page 140 .
