Key not authorised for the vehicle
If a key which is not authorised for this vehicle is inserted in the ignition
lock, it can be removed as follows:
● Automatic gearbox: the key cannot be removed from the ignition lock.
Press and release the selector lever locking button. Key can be removed
from the vehicle.
● Manual gearbox: Remove the key from the ignition.
WARNING
Unsuitable or careless use of the vehicle key could result in serious in-
jury.
● Always take all the keys with you whenever you leave the vehicle. The
engine could accidentally be started and electrical equipment such as
the windows could accidentally be operated resulting in serious injury.
● Never leave children or disabled people alone in the car. They could
be trapped in the car in an emergency and will not be able to get them-
selves to safety. For example, depending on the time of the year, temper-
atures inside a locked and closed vehicle can be extremely high or ex-
tremely low resulting in serious injuries and illness or even death, partic-
ularly for young children.
● Never remove the key from the ignition if the vehicle is in motion. The
steering may lock and it will not be possible to turn the steering wheel.
Note
● If the key is left in the ignition lock with the engine off for long periods,
the vehicle battery will run flat.
● For automatic gearbox vehicles the key can only be removed from the ig-
nition lock if the gear selector lever is in position P. In this case, press and
release the selector lever locking button. Starting the engine

WARNING
Cold start sprays could explode or cause a sudden increase in the engine
speed.
● Never use start boosters.
CAUTION
● An attempt to start the engine while driving or starting the engine imme-
diately after turning it off can cause damage to the engine or starter motor.
● When the engine is cold, avoid high revs and heavy acceleration and do
not make the engine work hard.
● Do not push or tow start the engine. Sunburnt fuel could damage the
catalytic converter.
For the sake of the environment
Do not warm the engine at idle speed; start driving immediately if the visi-
bility is OK. This helps the engine reach operating temperature faster and
reduces emissions.
Note
● For example, if the key battery is very worn or flat, the engine cannot be
started with the starter button. In this case, remove the ignition button from
the lock and insert the key.
● Electrical components with a high power consumption are switched off
temporarily when the engine starts.
● When the engine is started cold, there may be strong vibrations for a few
moments for technical reasons. This is quite normal, and no cause for con-
cern.
● At temperatures below +5 °C (+41 °F), smoke may be given off below the
vehicle when the additional heater is connected. Stopping the engine

3.In automatic gearboxes, put the selector lever in position P.4.Connect the electronic parking brake ⇒ page 184.5.Turn the key in the ignition lock to position ⇒ Fig. 128 0.6.With a manual gearbox, put the vehicle in first or reverse gear.
WARNING
Never switch off the engine while the vehicle is moving. You may lose
control of the vehicle and there is a risk of serious accident.
● The airbags and belt tensioners do not work when the ignition is
switched off.
● The brake servo does not work with the engine off. To stop, the brake
pedal must be pressed with more force.
● As the power steering does not work if the engine is not running, you
will need more strength to steer than normally.
● If the key is removed from the ignition, the steering may lock and it
will not be possible to steer the vehicle.
CAUTION
If the engine has been driven at high speed for a prolonged period of time,
it may overheat when turned off. To avoid engine damage, allow the engine
to run for approximately two minutes in neutral before switching it off.

If the paddles are not used for a period of time, the vehicle leaves Tiptronic
mode.
CAUTION
● When accelerating, the gearbox automatically shifts up into the next
gear shortly before the maximum engine speed is reached.
● When reducing speed manually, the gear box only shifts gear when the
engine can no longer exceed the maximum engine speed.
Driving with an automatic gearbox
The gearbox changes up or down gears automatically as the vehicle moves.
Driving down hills
The steeper the gradient, the lower the gear you will need. The lowest gears
increase the engine braking work. Never go down hills with the selector lev-
er in neutral N.

● You should reduce speed accordingly.
● Press the selector lever from position D to the right into the Tiptronic se-
lector gate ⇒ page 181.
● Gently pull the selector lever back to change down a gear.
● ALTERNATIVELY: Reduce using the steering wheel paddles ⇒ page 181.
Back-up programme
If all the selector lever positions on the instrument panel display are shown
with a light-coloured background, this means there is a fault in the system.
The automatic gearbox will operate in back-up mode. When the backup pro-
gramme is activated, it is possible to drive the vehicle, however, at low
speeds and within a selected range of gears.
For the DSG ®
dual clutch gearbox, in some cases, this may mean that the
reverse gear does not engage . The gearbox should be checked by a special-
ised workshop as soon as possible.
Overload protection for the 6-speed DSG gearbox ®
When the clutch is overloaded, the vehicle begins to jerk and the selector
lever position indicator begins to flash. To prevent damage to the clutch,
this interrupts the power transmission between the engine and the gearbox.
There is no more traction and it is not possible to accelerate. If the clutch is
opened automatically due to overloading, press the brake pedal. Wait a few
seconds before starting to move again.
Kick-down
The kick-down system provides maximum acceleration when the gear selec-
tor lever is in the positions D, S or in the Tiptronic position.
When the accelerator pedal is pressed right down, the automatic gearbox
will shift down to a lower gear, depending on road speed and engine speed.
This takes advantage of the maximum acceleration of the vehicle ⇒
.
When the accelerator is pressed to the floor, the automatic gearbox shifts to
the next gear only after the engine reaches the specified maximum engine
speed. Launch-Control Programme
The Launch-Control programme enables maximum acceleration while at a
standstill.
●
Switch off the ASR ⇒ page 184.
● Press and hold the brake pedal with your left foot.
● Place the selector lever in position S or Tiptronic.
● Press the accelerator with the right foot until the vehicle reaches an en-
gine speed of approximately 3200 rpm.
● Lift the left foot off the brake ⇒
. The vehicle starts with maximum ac-
celeration.
● Turn on the ASR after accelerating!
WARNING
Rapid acceleration can cause loss of traction and skidding, especially on
slippery ground. This could cause loss of control of the vehicle resulting
in an accident and considerable damage.
● Only use kick-down and rapid acceleration when weather conditions,
surface conditions and traffic conditions permit; accelerate and drive in a
manner that does not endanger other road users.
● Please remember that the driven wheels can slip and the vehicle can
skid if the ASR is turned off, especially on slippery ground.
● Turn on the ASR after accelerating!
CAUTION
● If you stop on a hill with a gear range engaged, do not try to prevent the
vehicle from rolling back by pressing on the accelerator. This could cause
overheating and damage the automatic gearbox.
● Never allow the vehicle to move with the gear selector lever in N, espe-
cially with the engine turned off. The automatic gearbox will not be lubrica-
ted and could be damaged.

Braking, stopping and parking
Introduction
The assisted braking systems include the anti-lock braking system (ABS),
the brake assist system (BAS), the electronic differential lock (EDL), the trac-
tion control system (ASR) and the electronic stability control (ESC).
Additional information and warnings:
● Towing mode ⇒ page 236
● Start assist systems ⇒ page 195
● Wheels and tyres ⇒ page 296
● Accessories, parts replacement, repairs and modifications ⇒ page 260
WARNING
Driving with worn brake pads or a faulty brake system may lead to seri-
ous accident.
● If lights, alone or accompanied by a warning message on the in-
strument panel display, please go immediately to a specialised work-
shop to check the brake pads and to replace them if they are worn.
WARNING
Careless parking can cause serious injury.
● Never remove the key from the ignition if the vehicle is in motion. The
steering lock may engage and locked the steering wheel making the vehi-
cle impossible to control.
● Always park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as wood, leaves, spilled
fuel, dried grass, etc).
WARNING (Continued)
● Always apply the electronic parking brake when you leave your vehi-
cle and when you park.
● Never leave children or disabled people alone in the vehicle. They
could release the electronic parking brake, activate the selector lever or
gear stick and start the vehicle moving. This could result in a serious ac-
cident.
● Always take all the keys with you whenever you leave the vehicle. The
engine could accidentally be started and electrical equipment such as
the windows could accidentally be operated resulting in serious injury.
● Never leave children or disabled people alone in the car. They could
be trapped in the car in an emergency and will not be able to get them-
selves to safety. For example, depending on the time of the year, temper-
atures inside a locked and closed vehicle can be extremely high or ex-
tremely low resulting in serious injuries and illness or even death, partic-
ularly for young children.
CAUTION
● Special care should be taken when parking in areas with high kerbs or
fixed barriers. Objects protruding from the ground may damage the bumper
or other parts of the vehicle during manoeuvres. To avoid damage, stop be-
fore the wheels touched the barrier or kerb.
● Special attention is required when driving through entrances, over
ramps, kerbs or other objects. The vehicle underbody, bumpers, mudguards
and running gear, and the engine and exhaust system could be damaged as
you drive over these objects.

companied by the corresponding audible warning.
● To stop the braking process, release the button or press the accelerator.
WARNING
The incorrect use of the electronic parking brake may result in serious ac-
cident.
● Never use the electronic parking brake to brake the vehicle except in
an emergency. The braking distance is considerably longer, because
braking is only applied to the rear wheels. Always use the foot brake.
● Never accelerate from the engine compartment with the engine run-
ning and a gear or a gear range engaged. The vehicle could move, even if
the parking brake is applied.
Note
● In vehicles with a manual gearbox: When the clutch pedal is released
and the accelerator pressed at the same time, the electronic parking brake
is automatically released.
● If the vehicle battery is flat, it will not be possible to disconnect the elec-
tronic parking brake. Use the jump-start ⇒ page 340.
● When the electronic parking brake is applied or released, noises may be
heard.
● If the electronic parking brake has not been used for a long while, the
system sometimes performs automatic and audible checks while the vehi-
cle is at a standstill. Parking
When parking your vehicle, all legal requirements should be observed.
To park the vehicle
Complete operations only in the sequence given.
●
Park the vehicle on a suitable surface ⇒
.
● Press and hold the brake pedal until the vehicle comes to a standstill.
● Connect the electronic parking brake ⇒ page 186.
● For an automatic gearbox, move the selector lever to position P.
● Switch off the engine and release the brake pedal.
● Remove the key from the ignition.
● If necessary, turn the steering wheel slightly to lock the steering.

Brake assist systems
The brake assist systems ESC, ABS, BAS, ASR and EDL only operate when
the ignition is switched on. They contribute significantly to increasing active
safety.
Electronic Stability Control (ESC)
ESC reduces the risk of skidding and increases the vehicle stability by brak-
ing individual wheels under specific driving conditions. ESC detects critical
handling situations, such as understeer, oversteer and wheelspin on the
driven wheels. The system stabilises the vehicle by braking individual
wheels or by reducing the engine torque.
The ESC has limits. It is important to realise that the ESC is also subject to
the laws of physics. ESC will not be able to deal with all situations with
which drivers may be faced. For example, if the road surface changes sud-
denly then ESC will not be useful in all cases. If the vehicle suddenly enters
a section covered by water, mud or snow then ESC will not provide assis-
tance in the same way as on dry ground. If the vehicle loses its grip on the
ground and moves on a film of water (aquaplaning), the ESC will not be able
to assist the driver to control the vehicle due to the loss of adherence with
the road surface preventing braking and steering. If the vehicle is driven
through series of bends at high speed, the ESC will not always be as effec-
tive: the vehicle reaction to aggressive driving is not the same as at reduced
speeds. When driving with a trailer, ESC does not provide the same amount
of vehicle control as without a trailer.
Adjust your speed and driving style to road, traffic and weather conditions.
ESC cannot push the limits of the laws of physics; improve the transmission
available or maintain the vehicle on the road if a lack of driver attention cre-
ates an inevitable situation. Otherwise, ESC assists in maintaining vehicle
control in extreme situations and uses the movements of the steering made
by the driver to maintain the vehicle moving in the desired direction. If the
vehicle is driven at such a speed that it will leave the road before ESC can
intervene then the system cannot provide assistance. The ABS, BAS, ASR and EDL systems are incorporated into the ESC. The ESC
is always on. The ESC should only be turned off using the ASR button
⇒
Fig. 137 when traction is insufficient. Always remember to turn on the
ASR once more when the vehicle has traction again.
Anti-lock brake system (ABS)
ABS can prevent the wheels from locking during braking until just before
the vehicle stops thus helping the driver to steer the vehicle and maintain
control. This means that, even during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not remove your foot from the
brake pedal or reduce braking force!
● Do not “pump” the brake pedal, or reduce braking force!
● Maintain vehicle direction when braking fully.
● When the brake pedal is released or when the brake force is reduced,
ABS is turned off.
ABS control can be observed by vibration of the brake pedal and noise. You
should never expect the ABS to reduce the braking distance under any cir-
cumstances. Braking distances will increase when driving on gravel, recent
snow or on icy and slippery ground.
When driving on loose ground, the all-terrain configuration of the ABS is au-
tomatically turned on. When ABS is activated, the front wheels may lock
briefly. This shortens the braking distance in off-road situations as the
wheels are prevented from digging into loose surfaces. All-terrain ABS only
intervenes when driving in a straight line. When the front wheels are turned,
the normal ABS is activated.
Brake assist system (BAS)
The brake assist system may reduce the required braking distance. The
brake assist system boosts the braking force if you press the brake pedal
quickly in an emergency. As a result, the braking pressure increases rapidly,
the braking force is multiplied and the braking distance is reduced. This en-
ables the ABS to be activated more quickly and effectively.
