Automatic gearboxAutomatic gearbox*Information for driving with the 6-speed automatic gearbox* Your car is equipped with a
conventional 6-
speed automatic
gearbox.The maximum speed is reached in the 5th gear. The 6th gear serves as an economic driving programme, which is intended to reduce the fuel consumption. Shifting up and down
through the gears is performed auto-
matically. You can also, however, switch the gearbox over into the Tiptronic mode
. This mode makes it possible for you to also shift gears
manually

Starting-off and Driving – Depress the brake pedal fully and keep it depressed. – Press the Shiftlock button (button in
handle of the selector lever),
move the selector lever into the desired position, e.g.
D ⇒
page 134,
and then release the Shiftlock button.
– Wait a moment until the gearbox has shifted (a slight engagement
nudge can be felt).
– Release the brake pedal and depress the accelerator

.
Stopping for a short time – The selector lever position
N does not have to be selected when stop-
ping just for a short time, such as at
a cross roads. It is absolutely suffi-
cient to hold the stopped vehicle st
ationary by depressing the foot
brake. The engine can, howeve
r, be allowed just to idle.
Parking – Depress the brake pedal and hold it depressed. – Apply the handbrake firmly. – Press and Shiftlock button in the
selector lever, mo
ve the selector
lever to
P and then release the Shiftlock button.
The engine can only be
started
when the selector lever is in position
P or N
⇒ page 124. It is sufficient to engage selector lever position
P when parking on a flat surface.
When parking on a slope you should first apply the handbrake firmly and then move the selector lever into position
P. This is to ensure that there is no excessive
pressure acting on the lock mechanism and
that it is easier to subsequently move
the selector lever out of position
P.
If the selector lever position
N is selected by accident wh
ile driving it is first neces-
sary to release pressure on the accelerato
r pedal and wait for idling speed of the
engine to be reached before engaging a drive position in the selector lever.
WARNING
•
Do not depress the accelerator when changing the position of the
selector lever if the car is stationary and the engine is running - risk of acci- dent!•
Never move the selector lever into position R or P when driving - risk of
an accident!•
When the engine is running and the vehicle is stationary, it is necessary
to hold the car with the brake pedal in all the positions of the selector lever (except P and N) since the power transmission is never completely inter- rupted, also not when the engine
is idling - the vehicle "creeps".

Technical Data
Information for driving with the automatic gearbox DSG* The abbreviation DSG means Direct shift gearbox (Direct shift gearbox). Two independent clutches are needed for the power transmission between the engine and the gearbox.
These replace the torque converter
of the conventional automatic gearbox. Their shifting is matched in such a way that there are no jerks when shifting the gear and the power trans-mission of the engine to the front wheels is not interrupted. Shifting up and down through the gears is perf
ormed automatically. You can also,
however, switch the gearbox over into the
Tiptronic mode
. This mode
makes it possible for you to also shift gears manually
⇒
page 136.
Starting-off and Driving – Depress the brake pedal fully and keep it depressed. – Press the Shiftlock button (button
in handle of the selector lever),
move the selector lever into the desired position, e.g. in
D, and then
release the Shiftlock button.
– Release the brake pedal and depress the accelerator

Stopping for a short time – The selector lever position
N does not have to be selected when stop-
ping just for a short time, such as at
a cross roads. It is absolutely suffi-
cient to hold the stopped vehicle stationary by depressing the foot brake. The engine can, however, be allowed just to idle.
Parking – Depress the brake pedal and hold it depressed. – Apply the handbrake firmly. – Press and Shiftlock button in the selector lever, move the selector
lever to
P and then release the Shiftlock button.
The engine can only be
started
when the selector lever is in position
P or N
⇒ page 124. At temperatures below -10 °C the engine can only be started in the selector lever position
P.
It is sufficient to engage
selector lever position
P when parking on a flat surface.
When parking on a slope you should first apply the handbrake firmly and then move the selector le
ver into position
P. This is to ensure that there is no excessive
pressure acting on the lock mechanism and
that it is easier to subsequently move
the selector lever out of position
P.
If the selector lever position
N is selected by accident while driving it is first neces-
sary to release pressure on the accelerato
r pedal and wait for idling speed of the
engine to be reached before engaging a drive position in the selector lever.
WARNING
•
Do not depress the accelerator when changing the position of the
selector lever if the car is stationary an
d the engine is running - risk of acci-
dent!•
Never move the selector lever into position R or P when driving - risk of
an accident!•
If you are stopping at a hill (downhill section), never try to hold the car
stationary with the gear engaged by me
ans of the “accelerator”, this means
by letting the clutch slip. This can lead
to overheating of the clutch. If there is
a risk of overheating of the clutch due
to overload, the clut
ch is opened auto-
matically and the vehicle rolls backward - risk of accident!•
If you must stop at a slope, depress and hold the brake pedal, so that you
can prevent the vehicle from rolling back.
Caution
•
The double clutch on the automatic gear
box DSG is equipped with an overload
protection. If you make use of
the uphill function on a vehi
cle which is stationary or
driving slowly uphill, it will result in an
increase of thermal stress of the clutches.
•
An overheating of the clutches can be detected by the flashing of the selector
level indicator and the “jerk” of the clutches, finally the clutches are opened. The power transmission from the engine to the front wheels is interrupted and as a

result of this the vehicle can no longer be
driven. If the clutch opens automatically,
depress the brake pedal, wait a few se
conds and only then continue driving.
Selector lever positionsThe current selector lever position is in
dicated in the information display of the
instrument cluster
⇒fig. 154
. In the positions
D and
S the gear you have already
engaged will be additionally displayed on the display. P - Parklock The driven wheels are locked mechanically in this position. The Parklock must only be engaged when the vehicle is stationary

I f y o u w i s h t o m o v e t h e s e l e c t o r l e v e r i n to
or out of this position, you must press the
Shiftlock button in the handle of the selector lever and at the same time depress the brake pedal. If the battery is used, the selector leve
r cannot be moved out of the position
P.
R - Reverse Reverse gear must only be engaged when
the vehicle is stationary and the engine
idling
⇒
.
The brake pedal must be depressed and at the same time the Shiftlock must be pressed, if you wish to obtain the selector lever positions
R, P or N.
When the ignition is switched on and the selector lever is in position
R, the reverse
lights will come on. N - Neutral The transmission is in Neutral in this position. The brake pedal must be depressed (if the lever is in its position for longer than 2 seconds) in order to move the selector lever out of the position
N into the position
D or R, with the ignition switched on, on a vehicle travelling at less than 5 km/hour
or on a stationary vehicle. D - Drive, position for driving forward When the selector lever is in this position, the forward gears are shifted up and down automatically in line with engine load, vehicle speed and the dynamic shift programme. You must depress the brake pedal if you wish to move into position
D from
N when
the vehicle is travelling
at less than 5 km/hour or is stationary

.
In certain circumstances (e.g. when driving in mountainous regions or when towing a trailer) it may be beneficial to
select the manual shift programme
⇒page 136 for
a short time in order to adapt the gearbox ratios manually to the driving situations. S - Position for sporty style of driving Shifting up later into a higher gear make
s it possible to fully exploit the power
potential of the engine. The gearbox also then shifts down at higher engine speeds as in the position
D.
