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.

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

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.

When disposing of vehicle or parts of the airbag system, it is important
to comply with the national legal requirements.When are the airbags deployed?The airbag system is designed in such
a way that the driver and front passenger
airbag are deployed in the event of a
frontal collision
of major severity.
In the case of a
violent side crash
, the front side airbag* on the side of the car at
which the collision occurs, is deployed toge
ther with the rear side airbag and the
head airbag*. In certain accident situa
tions, the front airbags, side airbags as well as the relevant
head airbag may be
deployed together.
The airbags
are not deployed
in the case of
minor
frontal and side collisions, in the
case of rear-end collisi
ons and vehicle rollover.
Deployment factors It is not possible to state globally which
deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents vary greatly. An important role in this case
, for example, is played by factors such as
the type of object (hard, soft) against whic
h the vehicle impacts or the type of object
against which the vehicle impa
cts, the angle of impact,
the relative vehicle speed
during the accident etc. A decisive factor for the deployment of the airbags is the deceleration which occurs during a collision. The control unit analyses
the nature of the collision and activates
the relevant restraint system. If the vehi
cle deceleration which occurs and is meas-
ured during the collision remains below the prescribed reference values specified in the control unit, the airbags are not
deployed although the vehicle may well
suffer severe damage to the bodywork
as a consequence of the accident.
The airbags are not deployed if:•
ignition off,
•
a minor frontal collision,
•
a minor side collision,
•
a rear-end collision,
•
Rollover of the vehicleNote
•
A grey white, non harmful gas is released when airbag is inflated. This is
perfectly normal and is not an indi
cation of a fire in the vehicle.
•
The dash panel must be replaced afte
r the front passenger airbag has been
deployed.•
In the event of an accident in which the airbags are deployed: − The interior lighting comes on (if the switch for the interior light is in the door contact position), − The hazard warning light is switched on, − All the doors are unlocked, − the battery in the luggage compartment* is switched off, − the fuel supply to the engine is interrupted.

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you maintain control of your vehicle in situations in borderline driving situations such as when negotiating a curve too fast. The risk of skidding is reduced and your car thus offers greater driving stability depending on the conditions of the road surface. This occurs at all speeds. The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL),
•
Traction control system (TCS),
•
Active driver-steering recommendation (DSR),
•
Antilock brake system (ABS),
•
Brake Assist,
•
Uphill-Start off-Assist.
Operating principle The ESP switches on automatically when the engine is started and then conducts a self-test. The ESP control unit processes data from the individual systems. It also processes additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin
g pressure and the steering angle.
The direction which the driver wishes to ta
ke is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual behaviour of the vehicle. If differences exis
t, such as the car beginning to skid, the
ESP will automatically brake the appropriate wheel. The car is stabilised again by the forces which take effect when the wheel is braked. Intervention into the brake system takes place primarily on the outer front wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle to break away) while occurs this is on the inner re
ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied by noises. The ESP operates in combination with the ABS
⇒page 197. If there is a fault in the
ABS system, the ESP also does not operate. The ESP warning light lights up in the instru
ment cluster when there is a fault on the
ESP
 ⇒page 39.
Switching off You can switch the ESP off and on again
as you wish, by pressing the button
⇒ fig. 190
. The ESP warning light lights up in th
e instrument cluster when the ESP is
switched off
 ⇒page 39.
The ESP should normally always be switched
on. It may be good practice in certain
exceptional cases, such as when you wish
to have wheel slip, to switch off the
system. Examples:

when driving with snow chains
•
when driving in deep snow or on a loose surface
•
when it is necessary to rock a ca

then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle. Even if a vehicle fitted with ESP you should still always adapt your style of driving to the condition of the
road surface and the traffic situation.
This particularly applies when driving on slippery and wet roads. The increased safety offered must not tempt you to take greater risks than other- wise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling
circumferences of the tyres can lead to an
undesirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-
ment of tyres and wheels) can influence the function of the ESP
⇒page 241,
“Accessories, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock pr
events an individual wheel from
slipping.Models fitted with ESP are equipped with electronic differential lock (EDL). General The EDL makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio
ns of the road surface are unfavourable.
Operating principle The EDL is activated automatically, that is
without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should only
one
drive wheel begin spinning on a slippery surface there will be an
appreciable difference in the speed of the driven wheels. The EDL function brakes the slipping wheel and the differential transmits a greater driving force to the other driven wheel. This control proces
s is also accompanied by noises.
Overheating of the brakes The EDL switches off
automatically if unusually severe
stresses exist in order to
avoid excessive heat generation in the
disc brake on the wheel which is being
braked. The vehicle can continue to be driv
en and has the same characteristics as a
vehicle not fitted with EDL. The EDL switches on again
automatically as soon as the brake has cooled down.
WARNING
•
Depress the accelerator carefully when accelerating on uniformly slip-
pery road surfaces, such as ice and sn
ow. The driven wheels might still spin
despite the EDL and affect the stability
of the vehicle - risk of an accident!
•
You should always adapt your style of driving to the condition of road
surface and to the traffic situation even
when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•
If the ABS or ESP warning light comes on,
this may also indicate a fault in the
EDL. Please have the car inspected as s
oon as possible by a specialist garage.

rated when the engine is running.
WARNING
•
Never switch off the engine before the vehicle is stationary.
•
The brake booster only operates when the engine is running. Greater
physical effort for braking is required
when engine is switched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.Antilock brake system (ABS)ABS prevents the wheels locking when braking.General The ABS contributes significan
tly to enhancing the active
safety of your vehicle.
Compared to a car not fitted with the ABS brake system, you are able to retain optimal steering ability even during a fu
ll brake application on a slippery road
surface because the wheels do not lock up. You must not expect, however, that the br
aking distance will be shorter under all
circumstances as a result of the ABS. Th
e braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be longer. Operating principle The brake pressure will be reduced on a wheel which is rotating at a speed which is too low for the speed of the vehicle and tend
ing to lock. This control cycle is notice-
able from a
pulsating movement of the brake pedal
which is accompanied by
noises. This is consciously intended to provide the driver with the information that the wheels are tending to lock (ABS control range). You must always keep the brake pedal depressed to enable the ABS to optima
lly control the brake application in this
braking range. Never interrupt the application of the brakes!
WARNING
•
The ABS can also not overcome the physic
al limits of your vehicle. Please
do not forget this, particularly when driv
ing on icy or wet road surfaces. If the
ABS is operating within the control ra
nge, adapt your speed immediately to
the conditions of the road surface and the traffic situation. The increased safety offered by the ABS must not tempt you to take greater risks than otherwise - risk of an accident!•
The normal braking system is still fully
functional if there is an ABS fault.
Visit a specialist garage as quickly as po
ssible and adjust yo
ur style of driving
to take account of the ABS fault in the meantime since you will not know how great the damage is.

Brake Assist*During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the braking force and thus makes it possible to rapidly produce the pressure required in the brake system. The majority of drivers do
apply the brakes in good time in dangerous situations,
but do not depress the brake pedal with su
fficient pressure. Consequently, it is not
possible for the car to achieve its maxi
mum deceleration and the car covers a
greater distance than necessary. The Brake Assist is activated by the very quick operation of the brake pedal. In such cases, a much greater braking pressure ex
ists than during a normal brake applica-
tion. This makes it possible, even with a relatively low resistance of the brake pedal, to produce an adequate pressure in the brake system in the shortest possible time, which is required for maximum deceleration of the car. You must apply the brake pedal firmly and hold it in
this position in order to achieve the shortest possible
braking distance. The Brake Assist is able to help you achieve a shorter braking distance in emergency situations by rapidly producing the pressure
required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of the Brake Assist is automatically switched off and the brakes operate in the normal way. The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist function is also not available.
Further information on the ESP
⇒page 193.
WARNING
•
The Brake Assist is also not able to overcome the physical limits of your
car in terms of the braking distance required.•
Adapt your speed to the conditions of the road surface and to the traffic
situation.•
The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise.
Uphill-Start
off-Assist*
The uphill-start off-assist makes it much easier to start off on steep hills. The system assists a start off by holding the brake pr
essure produced by the brake pedal actu-
ation for approx. 2 seconds after releasing the brake pedal. The driver can therefore move his foot from the brake pedal to th
e accelerator pedal and start off on the
slope, without having to actuate the hand
brake. The brake pressure drops gradually
the more you operate the accelerator pedal. If the vehicle does not start off within 2 seconds, it starts to roll back. The uphill-start off-assist is active in the ev
ent of a 5% slope, if the vehicle door is
closed. It is alwa
ys active on slopes when in forward or reverse start off. When
driving downhill, it is inactive.Electromechanical power steeringThe power steering enables you to steer
the vehicle with le
ss physical force.
With the electromechanical power steering, the steering assist is automatically adapted to the speed and to the steering angle. It is still possible to fully steer the vehicle if the power steering fails or if the engine is not running (vehicle being towed in). The
only difference is that greater physical
effort is required. If there is a fault in the power steering, the warning light
 or  lights up in the
instrument cluster
⇒page 36.
WARNING
Contact your specialist
garage if the power steering is defective.
