Introduction
Applies to vehicles: with S tro nic/t iptronic
The automat ic transmission is controlled elec-
tronically. The transmission upshifts or down-
shifts automatically depending on which drive
program is se lected.
When a moderate driving style is used, the
transmission selects the most economica l
driving mode. It will then change up early and
de lay the downshifts to give 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
(t iptronic mode)

vehicle to accelerate without a noticeable in-
terruption in traction.

In the tiptronic transmission,
power is trans-
ferred by a torque converter.
