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 138.
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 126. 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 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 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 clutch 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 vehicle 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 clut ches, 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 positions
The 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 wise 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 138 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 makes 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.

Passive Safety165
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
For your own safety and to reduce the risk of injury in the event of an accident, we
recommend the following setting:
•Adjust the steering wheel so that the distance between the steering wheel and
your chest is at least 25 cm ⇒page 164, fig. 168 .
•Position the driver seat in the forward/back direction so that you are able to
press the pedals with your legs at a slight angle .
•Adjust the backrest so that you are able to reach the highest point of the steering
wheel with your arms at a slight angle.
•Adjust the head restraint so that the top edge of the head restraint is at the same
level as the upper part of your head ⇒fig. 169 .
•Fasten the seat belt correctly ⇒page 170, “How are seat belts correctly
fastened?”.
Manual driver seat adjustment ⇒page 12, “Adjusting the front seats”.
Electrical driver seat adjustment ⇒page 77, “Adjusting front seats electrically*”.
WARNING
•The front seats and the head restraints must always be adjusted to match
the body size of the seat occupant as well as the seat belts must always be
correctly fastened in order to provide an optimal protection for you and your
occupants.
•The driver must maintain a distance of at least 25 cm to the steering
wheel ⇒page 164, fig. 168 . Not maintaining this minimum distance will
mean that the airbag system will not be able to properly protect you -
hazard!
•When driving, hold the steering wheel with both hands firmly on the
outer edge in the 9 o'clock and 3 o'clock position. Never hold the steering
wheel firmly in the 12 o'clock position or in another way (e.g. in the middle
of the steering wheel or at the inner steering wheel edge). In such cases,
injuries to the arms, the hands and the head can occur when the driver
airbag is deployed.
•The backrests must not be angled to o far back when driving otherwise
this will affect proper operation of the seat belts and of the airbag system -
risk of injury!
•Ensure that there are no objects in the footwell as any objects may get
behind the pedals during a driving or braking manoeuvre. You would then
no longer be able to operate the clutch, to brake or accelerate.
Correct seated position for the front passenger
The front passenger must maintain a distance of at least 25 cm from
the dash panel so that the airbag offers the greatest possible safety
when an airbag is deployed.
For the safety of the front passenger and to reduce the risk of injury in the event of
an accident, we recommend the following setting:
•Adjust the front passenger seat as far as possible to the rear.
•Adjust the head restraint so that the top edge of the head restraint is at the same
level as the upper part of your head ⇒fig. 169 .
•Fasten the seat belt correctly ⇒page 170, “How are seat belts correctly
fastened?”.
In exceptional cases the front pass enger airbag can be deactivated ⇒page 181,
“Deactivating an airbag”.

– Release the clutch particularly gent ly when starting off or depress the
accelerator particularly gently if yo ur vehicle is fitted with an auto-
matic gearbox.
Driver of the towed vehicle
– Switch the ignition on so that the steering wheel is not blocked and you can also operate the turn signal lights, the headlight flasher, the
windscreen wipers and wi ndscreen washer system.
– Take the vehicle out of gear or move the selector lever into position N
if your vehicle is fitted with an automatic gearbox.
– Note that the brake servo unit and power steering only operate if the engine is running. You will require si gnificantly greater physical force
to depress the brake pedal and to steer the vehicle if the engine is not
running.
– Ensure that the tow rope is always kept taught.
Tow rope or tow bar
A tow bar is safest way of towing a vehicle and also minimizes any shocks. You can
use a tow rope only if a suitable tow bar is not available.
The tow rope must be elastic to protect the vehicle. Thus one should only use
plastic fibre rope or a rope made out of a similarly elastic material.
Only attach the tow rope to the towing eyes provided for this purpose ⇒page 254
and ⇒page 255.
Driving style
Towing another vehicle requires a certain amount of practice. Both drivers should
be familiar with the particular points about towing a vehicle. Unskilled drivers
should not attempt to tow in another vehicle or to be towed in.
One should be constantly vigilant not to allow impermissibly high towing forces or
jerky loadings. There is always a risk of excessive stresses and damage resulting at
the points to which you attach the tow ro pe or tow bar when you attempt to tow a
vehicle which is not standing on a paved road.
Caution
If the gearbox of your vehicle no longer contains any oil because of a defect, your
vehicle must only be towed in with the driven wheels raised clear of the ground, or
on a special vehicle transporter or trailer.
Note
•Please comply with any legal requirements particularly regarding the switched
on signal systems, when towing in or tow-starting another vehicle.
•The tow rope must not be twisted as it may in certain circumstances result in the
front towing eye being unscrewed out of your vehicle.
Front towing eye
The towing eye is stored in the box for the vehicle tool kit.
