Rapid acceleration can cause loss of traction and skidding, particularly on slippery roads. This
can cause you to lose control of the vehicle, which can lead to accidents and serious injuries.
•The kickdown function or fast acceleration should only be used if the visibility, weather,
road and traffic conditions permit.
WARNING
Never ride the brake pedal. Do not overuse the brake pedal. Constant braking will cause the
brakes to overheat. This can considerably reduce the brake effect, increase the braking
distance and, in certain circumstances, cause the brake system to fail completely.
WARNING
•Never let the brakes rub by applying light pressure to the brake when it is not necessary to
brake. This will increase levels of wear.
•Before driving down a long, steep gradient, reduce speed and change to a lower gear or in
vehicles with an automated manual gearbox in Tiptronic mode, move the selector lever to a
lower position. This will make use of the engine braking effect and relieve the load on the
brakes. The brakes could otherwise overheat and possibly fail. The brakes should only be
used to slow or stop the vehicle.
NOTICE

Fault in the automated manual gearbox
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Emergency programme
There may be a fault in the system if warning and indicator lamps for the automated manual
gearbox light up in the vehicle cluster ⇒ Warning and indicator lamp. When certain faults occur, the
automated manual gearbox runs in an emergency programme. The vehicle can still be driven in the
emergency programme, but only at reduced speed and not in all gears.
With an automated manual gearbox it may then be the case that the vehicle can no longer be
driven in all gears.
In all cases the automated manual gearbox should be checked by a qualified workshop
immediately.
Overheating in the automated manual gearbox
The automated manual gearbox can overheat, for example if the vehicle regularly pulls off from the
starting position or in stop-and-go traffic. Overheating is indicated by a warning lamp displayed
in the instrument cluster. An acoustic warning may also be heard. Stop the vehicle and allow the
gearbox to cool down ⇒.
The vehicle does not move forwards or backwards even though a position
has been selected
If the vehicle will not move in the required direction, the system may have selected the position
incorrectly. Depress the brake pedal and reselect the position.
If the vehicle still does not move in the required direction, there is a system fault. Seek expert
assistance and have the system checked.
Gear-change indicator (manual gearbox)
First read and observe the introductoryinformation and safety warnings⇒
Introduction
In some vehicles, the instrument cluster will show which gear should be selected while the vehicle
is in motion to reduce fuel consumption.
DisplayMeaning
The current gear is optimal.
A higher gear is recommended.
A lower gear is recommended.
Rapid acceleration can cause loss of traction and skidding, particularly on slippery roads. This
can cause you to lose control of the vehicle, which can lead to accidents and serious injuries.
•Always adjust your driving style in accordance with the flow of traffic.
•The kickdown function or fast acceleration should only be used if the visibility, weather,
road and traffic conditions permit.
•You should never endanger other road users through the acceleration of your vehicle or
through your driving style.
WARNING
If you stop the vehicle on an incline, do not attempt to stop it from rolling back by depressing
the accelerator while a position is still selected. The automated manual gearbox could
overheat and be damaged.
NOTICE
•If the display indicates that the gearbox is overheating for the first time, the vehicle will
have to be parked safely or driven faster than 20 km/h (12 mph).
•If the lamp signal and acoustic warning are repeated approximately every 10 seconds, the
vehicle must immediately be parked safely and the engine switched off. Allow the gearbox
to cool down.
•In order to prevent damage to the gearbox, you should not drive on until the lamp goes out.
You should not pull away or drive the vehicle at very low speeds while the gearbox is
overheated.
NOTICE

An acoustic warning is given if the car is driven faster than approximately 6 km/h (4 mph)
with the handbrake applied.
Parking
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Please adhere to relevant legislation when stopping and parking your vehicle.
Stopping the vehicle
The steps should only be carried out in the specified order.
•Stop the vehicle on a suitable surface ⇒.
•Depress and hold the brake pedal until the engine has stopped.
•Apply the handbrake firmly ⇒ Handbrake.
•With an automated manual gearbox, move the selector lever to position D or R.
•Switch off the engine and take your foot off the brake pedal.
•Remove the vehicle key from the ignition lock.
•Turn the steering wheel slightly if necessary to engage the steering lock mechanism.
•With a manual gearbox, select first gear for flat ground and uphill inclines, or reverse gear for
downhill inclines, and then release the clutch.
•Please ensure that all occupants, in particular children, leave the vehicle.
•Take all vehicle keys with you when you leave the vehicle.
•Lock the vehicle.
Additional points for ascending and descending inclines
Before switching off the engine, turn the steering wheel so that the front wheels will roll against the
kerb if the parked vehicle starts to move.
•When facing downhill, turn the wheels so that they face the kerb.
•When facing uphill, turn the wheels so that they face the centre of the road.
Incorrect use of the handbrake can cause accidents and serious injuries.
•The handbrake should never be used to brake the vehicle, except in emergencies. The
braking distance is considerably longer as only the rear wheels are braked. Always use
the foot brake.
•Never drive the vehicle with the handbrake lightly applied. This can overheat the brakes
and adversely affect the brake system. It can also cause premature wear to the rear brake
pads.
•Never activate the accelerator from the engine compartment if a position or gear has been
selected and the engine is running. The vehicle can start to move even if the handbrake is
applied.
WARNING
To avoid unintentional movement when parking the vehicle, first apply the handbrake firmly
and then remove your foot from the brake pedal.
NOTICE

If the front brake pads are tested, the rear brake pads should be tested at the same time.
Regularly check the thickness of the brake pads through the openings in the rims or from the
underside of the vehicle. If necessary, remove the wheels to carry out a comprehensive check.
Volkswagen recommends using a Volkswagen dealership for this purpose.
Brake assist systems
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The brake assist systems ESC, ABS, EBV, BAS, TCS, TC and EDL will only function when the
engine is running. They make a considerable contribution to active driving safety.
Electronic stability control (ESC)
The ESC helps to reduce the risk of skidding and to improve driving stability by braking individual
wheels in certain driving situations. The ESC detects critical driving situations such as oversteer,
understeer and wheelspin. The system supports the stabilisation process for the vehicle by targeted
braking or by reducing engine torque.
ESC has its limitations. It is important to realise that ESC cannot overcome the laws of physics.
ESC will not be able to assist in every situation faced by a driver. For example, ESC will not be able
New brake pads will not have the optimal braking effect when first fitted.
•New brake pads cannot generate the full braking effect during the first 320 km and must
first be run in. A reduced braking effect can be increased by applying more pressure to the
brake pedal.
•You must drive particularly carefully when driving with new brake pads in order to reduce
the risk of accidents, serious injuries and loss of control of the vehicle.
•Never drive too close to other vehicles when running in new brake pads, and never create
a driving situation that will place a heavy load on the brakes.
WARNING
Overheated brakes reduce the braking effect and considerably increase the braking distance.
•When driving downhill the brakes are placed under particular strain and become hot very
quickly.
•Before driving down a long, steep gradient, reduce speed and change to a lower gear or
move the selector lever to a lower position. This will make use of the engine braking effect
and relieve the load on the brakes.
•Non-standard or damaged front spoilers could restrict the airflow to the brakes and cause
them to overheat.
WARNING
Wet brakes or brakes coated with ice or road salt react more slowly and require longer
braking distances.
•Carefully apply the brakes to test them.
•Always dry brakes and clean off any coating of ice and salt with a few cautious
applications of the brake when visibility, weather, road and traffic conditions permit.
WARNING
Driving without the brake servo can considerably increase the braking distance and thus
cause accidents and serious injuries.
•Never allow the vehicle to roll if the engine is switched off.
•If the brake servo does not function or the vehicle is being towed, the brake pedal will have
to be depressed more forcefully as the braking distance will be increased due to the lack
of assistance for the brake system.
WARNING
•Never let the brakes rub by applying light pressure to the brake when it is not necessary to
brake. Continual pressure on the brake pedal will overheat the brakes. This can
considerably reduce the brake effect, increase the braking distance and, in certain
circumstances, cause the brake system to fail completely.
•Before driving down a long, steep gradient, reduce speed and change to a lower gear or
move the selector lever to a lower position. This will make use of the engine braking effect
and relieve the load on the brakes. The brakes could otherwise overheat and possibly fail.
The brakes should only be used to slow or stop the vehicle.
NOTICE

to assist every time that there is a sudden change in the road surface quality. If a section of dry
road is suddenly covered with water, mud or snow, ESC will not be able to assist in the same
manner as on a dry road. If the vehicle aquaplanes (drives on a layer of water rather than on the
road surface), ESC will not be able to assist in steering the vehicle as the contact to the road
surface has been interrupted and it is therefore no longer possible to steer or brake the vehicle.
Always adapt your speed and driving style to suit visibility, weather, road and traffic conditions. ESC
cannot defy the laws of motion, improve the available power output, or keep the vehicle on the road
if insufficient care and attention on the part of the driver causes the vehicle to leave the road.
Instead, ESC increases the possibility of keeping the vehicle under control and, in extreme on-road
driving situations, it assesses the driver’s steering input and helps the vehicle to continue in the
required direction. If the vehicle is driving at a speed that leads it to leave the road before the ESC
can provide any kind of support, the ESC will be unable to provide any assistance.
The ABS, BAS, TCS and EDL systems are integrated into the ESC. The ESC is always on.
Anti-lock brake system (ABS)
The ABS prevents the wheels from locking when the brakes are applied up until the point where the
vehicle is nearly stationary and assists the driver in steering the vehicle and keeping it under
control. This means that the vehicle is less likely to spin, even when the brakes are depressed fully:
•Depress and hold the brake pedal with force. Do not take your foot off the brake pedal or
reduce the force on the brake pedal!
•Do not pump the brake pedal or reduce the pressure on the brake pedal!
•Steer the vehicle while the brake pedal is fully depressed.
•The ABS will switch off when the brake pedal is released or if the pressure on the brake pedal is
reduced.
If the ABS is taking corrective action, there is a pulsing movement in the brake pedal and some
noise. However, ABS will not necessarily guarantee shorter braking distances in all conditions. The
braking distance could even be longer when braking on gravel or on fresh snow covering an icy or
slippery surface.
Electronic brake pressure distribution system (EBD)
Every vehicle's centre of gravity moves forwards whenever the brake is operated. This means that
the rear wheels are in danger of locking due to the lower traction. The electronic brake pressure
distribution system controls the brake pressure for the rear wheels and thereby ensures the
optimum distribution of brake pressure between the front and rear axles. Under normal conditions,
the system will prevent the rear from breaking away if too much brake pressure if applied to the rear
wheels. The electronic brake pressure distribution system is included in the ABS' scope of
functions.
Brake Assist system (BAS)
The brake assist system can help to reduce the braking distance. The brake assist system
reinforces brake pressure hydraulically when the driver depresses the brake pedal quickly in an
emergency situation. As a result, full braking power is made accessible very quickly, brake pressure
is increased and the braking distance reduced. In this way, the ABS is activated more quickly and
more effectively.
Do not reduce the pressure on the brake pedal. The brake assist system will switch off the
hydraulic brake servo automatically when the brake pedal is released or if the pressure on the
brake pedal is reduced.
Traction Control System (TCS) or Traction Control (TC)
The TCS or TC reduces the engine output if wheelspin occurs and adapts the output to suit road
surface conditions. TCS or TC helps the car to start moving, accelerate and climb gradients in
unfavourable road conditions.
Electronic differential lock (EDL)
The EDL is available for normal driving on straight roads. EDL brakes the wheel that has lost
traction and distributes the driving force to the other drive wheel. To prevent the disc brake of the
braked wheel from overheating, the EDL cuts out automatically if subjected to excessive loads. The
EDL will switch on again automatically when the brake has cooled down.

Switch off the engine, ignition and the mobile telephone before filling the tank and leave them
switched off during the process ⇒.
