, with the ignition switched on, on a vehicle travelling at less than 5 km/hour or on
a stationary vehicle.
The brake pedal must be depressed (if the le ver is in its position for longer than 2
seconds) in order to move the selector lever out of the position N into the position
R , with the ignition switched on, on a vehicl e 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 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.
The Shiftlock on the selector lever grip must be pressed when moving the selector
lever out of the position D into the position S.
WARNING
•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".
•You must on no account unintentionally operate the throttle (e.g. by
hand from the engine compartment) if a drive position is engaged when the car is stationary. The vehicle would ot
herwise immediately start off - also
when the handbrake is firmly applied - risk of an accident!
•You must move the selector lever into position P and firmly apply the
handbrake first before you or any othe r person opens the bonnet and starts
working on the engine when it is runn ing - risk of accident! Pay particular
attention to the warning instructions.
Selector lever lock
Automatic selector lever lock
With the ignition on, the selector lever is locked when it is in the positions P and N .
You must first of all depress the brake pedal in order to move the selector lever out
of this position. The warning light
⇒ page 26 lights up in the instrument cluster
as a reminder for the driver when the selector lever is in position P and N:
A time delay element ensures that the sele ctor lever is not blocked when rapidly
switching over the position N (e.g. from R to D). This does, for example, allow one
to seesaw out a stuck vehicle. The selector lever lock will click into place if the lever
is in the N position for more than 2 seconds without the brake pedal being pressed.
The selector lever lock is only active if th e vehicle is stationary or moving at speed
of less than 5 km/hour. The lock is switched off automatically into position N when
the car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the handle of selector lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
you press the Shiftlock button.
Keylock - Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the selector
lever is in position P. If the ignition key is withdrawn, the selector lever is blocked in
position P.

Kickdown function
The kickdown function provides you with maximum acceleration
power.
Depressing the accelerator pedal allows th e kickdown function to be activated in
the desired driving program. This function has precedence over the driving
programme and serves for maximum accelera tion of the vehicle when exploiting
the maximum power potential of the engi ne without taking into account the
current selector lever position ( D, S or Tiptronic ). The gearbox shifts down to one
or several gears in line with the driving state and the vehicle accelerates. The
gearbox does not shift up into the highes t gear until the engine has reached its
maximum revolutions for this gear range.
WARNING
Please note that using the kickdown fu nction can result in the driven wheels
spinning on a smooth or slippery road surface - risk of skidding!
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting up and
down through the gears is performed auto matically on the basis of pre-defined
driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the most
economical driving programme. Shifting up into a higher gear as soon as possible
and shifting down as late as possible will have a favourable effect on your fuel
consumption.
Adopting a sporty style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and frequent changes in speed, exploiting the
top speed of the car or depressing the a ccelerator pedal (kickdown function), will
cause the gearbox to switch over to this style of driving and shift down earlier with
frequent changes in gears in comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style of driving
is a continuous process. Irrespective of this it is, however, possible to switch or shift down into a dynamic shift programme by
depressing the accelerator rapidly. The
gearbox shifts down into a lower gear matching the speed of the car and this allows
you to accelerate rapidly (e.g. when overtaking) without having to depress the
accelerator pedal fully into the kickdown range. The original programme will be
reactivated to match your particular style of driving once the gearbox has shifted up
again.
When driving in hilly regions, the gears are selected to match uphill and downhill
sections. This avoids the gearbox frequently shifting up and down when negotiating
an uphill stretch. When driving downhill, it is possible to shift down into the
Tiptronic position, in order to exploit the engine brake torque.
Tiptronic
The Tiptronic allows the driver to also shift gears manually.

switch over to manual shifting by pressing the right rocker switch
for more than 1 second.
Emergency programme
An emergency programme exists in the event of a fault in the system.
The gearbox operates in a corresponding emergency programme if there are func-
tional faults in the gearbox electronics. This is indicated by all of the segments in the
display lighting up or going out.
A functional fault can ha ve the following effect:
•The gearbox only shifts into certain gears.
•The reverse gear R cannot be used.
•The manual shift programme (Tiptronic) is switched off in the emergency mode.
If the gearbox has switched over to emergency mode, drive to the nearest
specialist garage in order to have the fault rectified.
Selector lever-emergency unlocking (DSG)
In case of interruption of the power supply (e.g. flat vehicle battery, defec-
tive fuse) or defect of the selector lever lock, the selector lever can no
longer be shifted from the position P in the normal way and the vehicle
can no longer be moved. The selector lever must be unlocked in case of
emergency.

WARNING
Even with this additional function the vehicle cannot be steered automati-
cally! The driver is furthermore fully reponsible for the steering of the
vehicle!
Brakes
What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions
of the vehicle and your style of driving. Particularly if you drive a great deal in towns
and over short distances or if you adopt a sporty style of driving, it may be neces-
sary to have the thickness of the brake pads inspected at a specialist garage
between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain condi-
tions such as when driving through water, during heavy rain showers or after the
vehicle has been washed in an automatic vehicle wash, since the brake discs and
brake pads may be moist or even have a coating of ice on them in winter. You
should dry the brakes as soon as possib le (by applying and releasing the brakes
several times, if the road conditions and the traffic situation allows it).
There also may be a certain delay before the full braking efficiency is available when
driving on roads which have been treated wi th road salt if you have not used the
brakes for some considerable time beforeha nd. The layer of salt on the brake discs
and brake pads must first be rubb ed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been
parked for a long period and if you do not make much use of the braking system.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro-
sion is present ⇒. Faults in the brake surface
If you notice that the braking distance
has suddenly become longer and that the
brake pedal can be depressed further, it is possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist garage
without delay in order to have the problem rectified. Drive at a reduced speed while
on your way to the dealer and adapt your style of driving to the higher brake pedal
pressure required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The
level of the brake fluid is monitored electronically ⇒page 34, “Brake system ”.
WARNING
•Only apply the brakes for the purpos e of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users
in jeopardy.
•When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced
otherwise the braking sy stem could run too hot.
•Allow for the fact that new brake pads do not achieve their full braking
efficiency until approximately 200 kilo metres. New brake pads must be first
“run in” before they develop their optimal friction force. You can, however,
compensate for this slightly reduced braking force by increasing the pres-
sure on the brake pedal. This guidelin e also applies to any new brake pads
installed at a future date.
Caution
•Never allow the brakes to ru b by applying slight pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer
braking distance and excessive wear.
•Before negotiating a steep downhill sect ion, please reduce your speed, shift
down into the next lower gear (manual ge arbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of the

Driving and the Environment
A new engine
The engine has to be run in during the first 1 500 kilometres.
Up to 1 000 kilometres
– Do not drive faster than 3/4 of the mamimum speed of the gear in use,
that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1 000 up to 1 500 kilometres
– Increase the power output of the engine gradually up to the full
speed of the gear engaged, that is up to the maximum permissible
engine revolutions.
During the first operating hours the engine has higher internal friction than later
until all of the moving parts have harmonized. The driving style which you adopt
during the first approx.1 500 kilometres plays a decisive part in the success of
running in your car.
You should not drive at unnecessarily high engine revolutions even after the
running-in period is complete. The maximum permissib le engine speed is marked
by the beginning of the red zone on the scale of the revolutions counter. Shift up
into the next higher gear on a vehicle fitted with manual gearbox before the red
zone is reached. Extremely high engine revolutions are automatically governed, by
the way.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do
not drive at engine revolutions which are too low. Shift down as soon as the engine
is no longer running smoothly.
Caution
All the speed and engine revolution figure s apply only when the engine is at its
normal operating temperature. Never rev up an engine which is cold, neither when
the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a higher gear as
early as possible are ways to minimise fuel consumption and operating noise levels
and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first. You should
take account of this fact for the first 500 kilometres and drive particularly carefully.
New brake pads
Allow for the fact that new brake pads do not achieve their full braking efficiency
until approximately 200 kilometres. New brake pads must be first “run in” before
they develop their optimal friction force. You can, however, compensate for this
slightly reduced braking force by increa sing the pressure on the brake pedal.
This guideline also applies to any new brake pads installed at a future date.
During the running-in period , you should avoid excessive stresses on the brakes.
This includes, for example, violent braking, particularly from very high speeds, and
also when crossing mountain passes.

The fuel consumption can naturally also be
influenced by factors which are beyond
the driver's control. It is, for example, normal for the fu el consumption to increase
in winter and under worsened conditions such as poor road conditions, towing a
trailer, etc.
The technical requirements for low fuel usage and economic efficiency of the
vehicle have already been built into the ve hicle at the works. Special attention has
been given to minimising ne gative effects on the environment. It is necessary to
take note of the guidelines given in this chapter in order to make best use of these
characteristics and to maintain their effectiveness.
The optimal engine speed should be obtain ed when accelerating, in order to avoid
a high fuel consumption an d resonance of the vehicle.
Looking ahead when driving
A vehicle's highest fuel consumption occurs it accelerates.
Avoid accelerating and brakin g unnecessarily. If you drive with forsight you will not
need to brake so often and will also then not have to accelerate so much. Let your
vehicle coast to a stop, for example, if this is possible, when you see that the next
set of traffic lights is at red.
Shifting gears and saving energy
Shifting up early saves on fuel.
Manual gearbox
– Drive no more than about one length of your vehicle in first gear.
– Always shift up into the next higher gear at approx. 2 000 to 2 500 revs.
Automatic gearbox
– Depress the accelerator pedal slowly. Do not depress it beyond the
kickdown position, however.
An effective way of achieving good fuel economy is to shift up early. You will
consume more fuel if you drive at unnecessa rily high revolutions in any given gear.
The ⇒fig. 179 shows the ratio of fuel consumption to the speed of your vehicle in
the relevant gears. Fuel consumption in 1st gear is the highest, while that in 5th or
the 6th gear is the lowest.
Only depress the accelerator pedal slowly if your vehicle is fitted with an automatic
gearbox in order to automatically select an economic driving programme. You will
achieve good fuel economy by shifting up early and shifting down late.
Note
Also use the information supplied by the multi-functional indicator* ⇒page 14.
