Automatic Transmission
S tronic ®, tiptronic
Introduction
Applies to vehicles: with S tronic/tiptronic
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 ear ly 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 se lect the gears
manually (t iptronic mode ) i=> page 113.
Various automatic transmissions may be in­
stalled, depending on the model:
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 .

yo ur vehicle when the engine is running,
act ivate the parking brake and move the

- Before driv ing down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
peda l too often or too long when dr iving
down a hill. Constant braking causes the
brakes to ove rheat and s ubstant ially re­
duces braking per formance, increases
braking distance or causes comp lete fail ­
ure of the brake system.
- To prevent the veh icle from rolling back
when stopping on inclines, a lways hold it
in place with the bra ke peda l or parking
brake.
- Never hold the ve hicle on an inc line with
a slipping clutch . The clutch opens auto­
matically when it becomes too hot from

erwise, any increase in engine speed may
set the veh icle in motion, even with the

vate the pa rking brake or press the bra ke
peda l to preven t the vehicle from roll ing.
- Allowing th e vehicle to ro ll when the en­
gine is stopped and the selecto r lever is
in N will d amage the tr ansmission be­
cause it is not l ubricated unde r those cir ­
