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 func
tion 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 de
tected 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.

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

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 lockAutomatic 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 33 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 select
or 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 programmeThe 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 freq
uent 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.

WARNING
Even with this function the vehicle ca
nnot steer itself! The
driver is further-
more responsible for the steering of the vehicle!BrakesWhat 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 br
akes 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. 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 yo
u 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 41, “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 th
eir 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 slig
ht 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 EnvironmentA new engineThe 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 spee
d 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 tyresNew 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 padsAllow 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 increasing 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.
