transmission S tronic-transmission
Introduction
Appl ies to vehicles: with S tro nic tr ansmiss ion
Your vehicle is equipped with an electronical­
ly-controlled DSG transmission called S tronic.
Two independent clutches transfer the power
between the engine and transmission. It al­
lows the vehicle to accelerate without a no­
ticeable interruption in traction .
The 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 economica l
driving mode. The transmission upshifts at a
lower RPM and downshifts at a higher RPM to
improve fuel efficiency.
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) o page 115,
Shifting manually (tiptronic mode).
Selector lever positions
A pp lies to vehicles: with S tro nic tr ansmiss ion
Fig. 105 Instrument cluste r: selector leve r positions
The instrument cluster display shows the cur­
rent selector lever position and current gear .
P -Park
The wheels are mechanically locked in this po­
s iti on. You can only shift into Park when the
vehicle is
stationary o &..
To shift in and out of the P selector lever posi­
tion, press the interlock button in the selector
lever
while pressing the brake peda l.
R- Reverse
Only shift into reverse gear when the vehicle is
stationary and the engine is running at idle
speed
o &. .
To select the R selector lever position, press
the interlock button
while pressing the brake
pedal. The back-up lights switch on in the R
pos ition if the ignition is switched on .
N -Neutral
The transmission is in idle in this position.
D/S - Normal position for driving forward
In the D/S selector lever position, the trans ­
mission can be operated either in the normal
D mode or in the S sport mode. To select the S
sport 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 .
Se lect the
sport mode S for sporty driving.
The vehicle makes full use of the engine'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/
h) or be stationary
o &. .

Under certain circumstances, (such as driving
in the mountains or towing a tra iler), it may
be usefu l to switch temporarily to the manual

When parking on a level surface, simply place
the selector leve r in the P pos ition. On in­
clines, activate the parking bra ke first and
then move the selector lever to the P posit ion

nism from being loaded too heavily and wi ll
~ make it easier to move the selector lever out

A WARNING
- The vehicle can roll even when the en­
gine is sw itched 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 running at idle . To
prevent the vehicle from "c reeping", you
must keep your foot on the brake when
the engine is running and the se lector
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
immed iate ly, even if the parking brake is
set. Th is could resu lt in a crash.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the engine is running.
- Never engage the R or P selector leve l
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 ra ki ng distance or causes complete fa il­
ure of the brake system.
- I f you must stop on an in cl ine, always
hold the vehicle in place with the foot
bra ke or parking brake to p reven t it from
rolling back .
- Neve r hold the vehicle on an incline with
a slipping clutch . The clutch opens a uto -

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. The selector lever must be
firmly in the
P pos it ion and locked in
place and the pa rking brake must be set
¢ page 214. Otherwise, the veh icle
cou ld beg in moving when the eng ine
speed is high, even with the parking
brake set.
@ Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator peda l while a driving gear
i s selected. This can cause the automatic
transmission to overheat and can dam­
age it. Set the park ing brake or press the
brake pedal to prevent t he veh icle from
r o lli ng .
- Allow ing the vehicle to roll when the en­
gine is stopped and the selector lever is

matic transmission beca use it is not lu­
bricated unde r those circu mstances.
- The transm ission can ove rheat and be
damaged under certa in driving and traf­
fic conditions such as frequent starts,
creeping for a long time, or s top-and -go

(D Tips
For safety reasons, the park ing brake re­
leases automatically only when the driver's
door is closed and dr iver's safety be lt is
fastened.
Hill descent control
Applies to veh icles: w ith S tronic transm iss io n
Hill descent control assists the driver when
driving down hills .
Hill descent contro l is activated when these­
lector lever is in the Dor 5 position and you
press the brake pedal. The transm ission auto­
matically selects a gear that is su itab le for the
incl ine. Hill descent cont ro l tries to ma inta in
t h e speed ac hieved at the t ime of b raking,
within physica l and tec hni cal limitations. If
may sti ll be necessary to ad just the speed
with the brakes . Because hill descent control
cannot shift down farther than 3rd gea r, it
may be necessary to sh ift into t iptronic mode
i n very steep areas . In this case, shift into 1st
or 2nd gear in t iptron ic mode to use the en­
gine's brak ing force to relieve the brakes .
Hill descent contro l sw itches off once the h ill
levels out or you press the accelerator pedal.
On vehicles with a cruise contro l system*
¢ page 85, hill descent control is also activat ­
ed when the speed is set.
A WARNING
--
H ill descent control cannot overcome
physical lim itations, so it may not be ab le
to maintain a constant speed unde r a ll
conditions. A lways be ready to apply the
b rakes.
