transmission S tronic-transmission
Introduction
Applies to vehicles: with S tronic transmiss ion
Your vehicle is equipped with an electronical­
l y -controlled DSG transmission called S tronic.
T wo independent clutches transfer the power
between the engine and transmission. It al­
lows the vehicle to accelerate without a no­
ticeable interruption in traction .
T he transmission upshifts or downshifts auto­
matically. The driving style continuously influ­
ences the selection of the driving program .
When a
moderate driving style is used, the
transmission selects the most econom ica l
driving mode. The transmission upshifts at a
lower RPM and downshifts at a higher RPM to
improve fuel effic iency .
T he 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 114,

mission can be operated either in the normal
D mode or in the S sport mode. To select the S
spor t mode, pull the selector lever back brief­
ly. Pulling the lever back again will select the
normal D mode . The instrument cluster dis­
play shows the selected driving mode.
In the
normal mode D, the transmission auto­
matically selects the suitable gear ratio . It de­
pends on engine load, vehicle speed and driv­
ing style .
Select the
sport mode S for sporty driving .
The vehicle makes full use of the eng ine's
power. Shift ing may become noticeable when
acce lerat ing.
To move from selector lever position N to D,
you must press the brake pedal and the vehi­ cle must be traveling less than 1 mph (2 km/

If the selector lever is not in the P position
when you open the driver's door, the vehicle
could ro ll. In vehicles with a convenience key*,
the following message appears:
Sh ift to P,
othe rwise veh icle c an roll a way. Door s do not
lock if le ver is not in P.
You will also hear a
warn ing tone.

Under certain circumstances, (such as driving
in the mountains or towing a tra iler), it may
be usefu l to sw itch temporarily to the manual
shift p rogram in order to adjust the gears to
the dr iving condit ions by hand
¢ page 114.
When parking on a level surface, simply place
the selector lever in the P pos ition. On in­
clines , activate the parking bra ke first and
then move the selector lever to the P pos it ion
¢ page 80 . This prevents the locking mecha­
nism from being loaded too heavi ly and will
make it easier to move the selector lever out
of the P position.
A WARNING
- The vehicle can roll even when the en­
g ine is switched off.
- Unintended vehicle movement can lead
to serious injuries .
- Never leave your vehicle with the engine running while in gear. If you must leave
your veh icle when the engine is running,
set the parking brake and move these­
lector lever to the P position .
- Power is still transferred to the wheels
when the engine is runn ing at idle. To
prevent the vehicle from "c reeping", you
must keep you r foot on the brake when
the engine is running and the selector lever is in the D, Sor R position or "tip­
tronic" mode is selected . -
-Do not inadvertently press the accelera­
tor peda l when the vehicle is stationary.
Otherwise the vehicle wi ll start to move
immediate ly, even if the parking brake is
set. Th is could result in a crash.
- Do not press the accelerator pedal when
changing the se lector lever position
while the veh icle is stationary and the
engine is running.
- Never engage the R or P selector level positions while dr iv ing. It could cause a
crash .
- Before driving 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
pedal too often or too long when driving
downhill . Constant braking causes the
brakes to overheat and substantially re­
duces braking pe rformance, increases
b rak ing distan ce or causes complete fa il­
ure of the brake system.
- I f you must stop on an in cl ine, always
hold the vehicle i n place with the foot
brake or park ing brake to p revent it from
rolling back .
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto ­
matica lly when it becomes too hot from

ed .
-If the engine must run while you are
working in the eng ine compartment with
the hood open, make sure a gear is not engaged . T he selecto r leve r must be
firmly in the P pos ition and locked in
pla ce and t he pa rking brake must be set
Qpage217. Otherwise, the veh icle
cou ld beg in moving when the eng ine
speed is high, even with the parking
brake set.
W Note
- When stopping on an incline, do not try
to ho ld the vehicle in place by pressing
the accelerator peda l w hile a dr iving gear
i s selected. This can cause the automatic
transmission to overheat and can dam­
age it. Set the parking b rake or press the
brake pedal to p revent the veh icle from
ro lling .
- Allow ing the ve hicle to roll when the en­
gine is stopped and the selector lever is
i n the N position will damage the auto­
matic transmission beca use it is not lu­
b ricated unde r tho se c ircumstances.
- The t ransm ission can overheat and be
damaged under certa in d riving and traf­
fi c condition s suc h as frequent s tarts ,

Automa tic tran sm iss ion 113
Hill descent control
App lies to vehicles : wi th 5 tronic tra nsmi ssio n
Hill descent control assists the driver when
driving down hills .
Hill descent control is activated when these­
l ector lever is in the D or S position and you
press the brake peda l. The transmission auto ­
matically selects a gear that is suitable for the
i ncl ine. Hill descent cont ro l t ries to ma inta in
t h e speed ac hieved a t the t ime of b raking,
within physic al and tec hnical lim it a tions. If
may sti ll be ne cessa ry to adju st the speed
with t he b rakes . Because hi ll descent control
cannot sh ift down farthe r than 3rd gear, it
may be necessary to sh ift into t iptronic mode
in very steep areas. In this case, shift into 1st
o r 2nd gear in tiptro nic mode to use the en­
gine's brak ing force to relieve the brakes .
Hill descent control switches off once the hi ll
levels out or you press the accelerator pedal.
On vehicles with a cruise contro l system*
Q page 83, hill descent control is also activat ­
ed when the speed is set .
A WARNING
-
Hill descent control cannot overcome
physical lim itations, so it may not be ab le
to maintain a co nsta nt speed unde r all
conditions . A lways be ready to apply the
b rakes .
