Transmission S tronic
Introduction
The automat ic transm iss ion is controlled elec
tronically. The transmiss ion upshifts or down
shifts automatically depend ing on which drive
p rogram is se lected.
When a
moderate driving sty le is used, the
transmission selects the most econom ica l
d riving mode.
It w ill then change up early and
de lay the downshifts to g ive better f uel econ
omy .
The transmis sion swi tches to a sporty mode
after a k ick-down or when the dr iver uses a
sporty driving sty le characterized by quick ac
celerator peda l movements, heavy accelera
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the drive r can a lso se lect the gears
manually ( tiptronic mode ) ~ page 87.
The S tronic is a dual-clut ch tra nsmission.
P ower is transfe rred using two clutches that
work independently from one another . They
rep lace the torq ue converter used in conven
tional automatic transmiss ions and allow the
vehicle to accelerate without a noticeable in
terruption in traction.

When accelerating, the transmission does
not
automatically shift to the next gear shortly
before the max imum pe rm itted engine RPM is
reached.
If you have selected a lower gear than the cur
rent one, the automatic transmission will shift
down only when the engine w ill not be over
revved.
With kick-down , the transm ission shifts into a
lower gear depend ing on speed and engine
RPM .
(D Tips
Tiptronic is inoperat ive when the transmis
sion is in the fail-safe mode .
, Kick-down
Kick-down enables maximum acceleration.
When you depress the accelerator peda l be
yond the resistance point, the automatic
transmission downshifts into a lower gear, de
pending on vehicle speed and eng ine speed .
The upshift into the next higher gear takes
place once the max imum specified engine
speed is reached .
.&_ WARNING
Please note that the whee ls can spin if
kick-down is used on a smooth slippery
road -there is a risk of skidding.
