Automatic Transmission
S tronic, tiptronic
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 (tiptronic mode) r:::> page 113.
Various automatic transmissions may be in­
stalled, depending on the mode l:
S tronic transmission
The 5 tronic is a dual-clutch transmission .
Power is transferred using two clutches that
work independently from one another . They
replace the torque converter used in conven­
tional automatic transmissions and allow the
vehicle to accelerate without a noticeable in­
terruption in traction.
tiptronic transmission
In the tiptronic transmission, power is trans­
ferred by a torque converter.

- Do not ride the brakes or press the brake
peda l too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substant ially re­
duces braking performance, increases
braking d istance or causes comp lete fail­
ure of the brake system.
- To prevent the veh icle from rolling back
when stopping on inclines, always hold it in place with the brake peda l or parking
brake.
- Never hold the veh icle on an incl ine with
