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.

Driving with worn brake pads or with a faulty brake system can cause accidents and serious
injuries.
•If you have reason to believe that the brakes are worn down or the brake system is faulty,
go to a qualified workshop immediately and have the brake system checked and have any
worn brake pads replaced.
WARNING
Incorrect parking can cause serious injuries.
•Never remove the vehicle key from the ignition lock when the vehicle is in motion. The
steering lock may be activated and you will no longer be able to steer or control the
vehicle.
•Never park the vehicle where parts of the exhaust system can come into contact with
inflammable material underneath the vehicle, e.g. leaves, dry grass, spilt fuel.
•Always apply the handbrake fully when the vehicle is parked.
•Never leave children or people requiring assistance alone in the vehicle. They could
release the handbrake, move the selector lever or gearshift lever and thus set the vehicle
in motion. This can lead to accidents and serious injuries.
•Always take all vehicle keys with you every time you leave the vehicle. The engine can still
be started and electrical equipment such as the window controls still can be operated,
potentially causing serious injury.
•Never leave children or people requiring assistance alone in the vehicle. They could
become trapped in the vehicle in an emergency and may not be able to get themselves to
safety. For example, locked vehicles may be subjected to very high or very low
temperatures, according to season. This can cause serious injuries and illness or
fatalities, especially for small children.
WARNING
•To avoid unintentional movement when parking the vehicle, first apply the handbrake firmly
and then remove your foot from the brake pedal.
•Always take care when driving in car parks with protruding kerbstones or bollards. Objects
that protrude from the ground can damage the bumper and other components when
parking the vehicle. In order to avoid any damage, stop the vehicle before the wheels
touch the bollards or kerbs.
•Drive carefully through dips in the road, over driveways, ramps, kerbstones and other
objects. Low-lying vehicle components such as the bumper, spoiler and parts of the
running gear, engine or exhaust system could be damaged.
NOTICE

Information on the brakes
First read and observe the introductoryinformation and safety warnings⇒
Introduction
New brake pads cannot generate the full braking effect during the first 200 to 300 km and must first
be run in ⇒. However, you can compensate for the slightly reduced braking force by applying
more pressure to the brake pedal. During the run-in period, the braking distance is longer when
the brakes are depressed fully or during emergency braking than with brakes that have been fully
run in. In the run-in period, the brakes should not be depressed fully and situations that create a
heavy load on the brakes should be avoided. For example, when driving too close to the vehicle
ahead.
The rate of wear of the brake pads depends to a great extent on the conditions under which the
vehicle is operated and the way in which the vehicle is driven. With regular urban trips, short
journeys and a sporty driving style, the brake pads must be checked by a qualified workshop more
regularly than stated in the service schedule.
When driving with wet brakes, for example after driving through water, after heavy rainfall or after
washing the vehicle, the braking effect may be delayed as the brake discs will be wet, or possibly
iced up (in winter). The brakes must be dried as quickly as possible by careful braking at higher
speed. Please ensure that no following vehicle and no other road user is put at risk as a result of
this action ⇒.
Any layer of salt accumulated on the discs and pads will delay the braking effect and increase the
braking distance. If the brakes on the vehicle have not been applied for a long time on roads that
have been gritted with salt, the layer of salt must be reduced through careful braking ⇒.
Corrosion on the brake discs and dirt in the brake pads are facilitated through long periods of
inactivity, low mileage and low load levels. If the brake pads have been hardly used, or if they are at
all corroded, Volkswagen recommends that the brake discs and brake pads be cleaned by braking
strongly several times from high speed. Please ensure that no following vehicle and no other road
user is put at risk as a result of this action ⇒.
Fault in the brake system
A brake circuit may have failed if you have to reduce speed and the vehicle does not brake as
normal (sudden increase in braking distance). This is indicated by the warning light . Go to the
nearest qualified workshop immediately to have the fault corrected. Drive at low speed when doing
this and anticipate much longer braking distances and an increase in the pressure required on the
pedal.
Brake servo
The brake servo will only function when the engine is running and reinforces the pressure applied
by the driver on the brake pedal.
If the brake servo is not functioning 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 ⇒.
The components of the exhaust system become very hot. This can cause fires and serious
injuries.
•Never park the vehicle where parts of the exhaust system can come into contact with any
inflammable material underneath the vehicle, e.g. leaves, dry grass, spilt fuel.
WARNING
•To avoid unintentional movement when parking the vehicle, first apply the handbrake firmly
and then remove your foot from the brake pedal.
•Always take care when driving in car parks with protruding kerbstones or bollards. Objects
that protrude from the ground can damage the bumper and other components when
parking the vehicle. In order to avoid any damage, stop the vehicle before the wheels
touch the bollards or kerbs.
•Drive carefully through dips in the road, over driveways, ramps, kerbstones and other
objects. Low-lying vehicle components such as the bumper, spoiler and parts of the
running gear, engine or exhaust system could be damaged.
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

Before using a particular brake fluid, check that the specifications printed on the container
correspond to the vehicle requirements.
Brake fluid that is compliant with VW standard 501 14 is available from Volkswagen dealerships.
If this brake fluid is not available and it is necessary to use another high-quality brake fluid instead,
brake fluid that is compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4 can
be used.
Not all brake fluids that are compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116
DOT 4 have the same chemical composition. Some of these brake fluids may contain chemicals
that can damage or destroy brake system components over time.
Volkswagen therefore recommends the use of brake fluid that is compliant with
VW standard 501 14 to ensure sustained optimal operation of the brake system.
Brake fluid that is compliant with VW standard 501 14 fulfils the requirements of DIN ISO 4925
CLASS 4 or US standard FMVSS 116 DOT 4.
Brake fluid level
The brake fluid level must always be between the MIN and MAX marking on the brake fluid
container or above the MIN marking ⇒.
The brake fluid level cannot be checked accurately in all models as engine components may
partially conceal the brake fluid container. If the brake fluid level cannot be read exactly, please
proceed to a qualified workshop.
The brake fluid level drops slightly when the vehicle is being used as the brake pads wear and the
brakes are automatically adjusted.
Changing the brake fluid
The brake fluid must be changed as indicated in the service schedule ⇒BookletService schedule,.
The brake fluid should be changed by a qualified workshop. Volkswagen recommends using a
Volkswagen dealership for this purpose. Only brake fluid that conforms with the required
specification should be used.
Brake fluid can pollute the environment. Any spilt service fluids must be cleaned up and
disposed of properly.
Brake failure or reduced braking effect can be caused by the brake fluid level being too low or
by brake fluid that is too old or unsuitable.
•The brake system and brake fluid level must be checked regularly.
•The brake fluid should be changed regularly, according to the service schedule
⇒BookletService schedule,.
•Heavy use of the brakes may cause a vapour lock if the brake fluid is left in the system for
too long. Vapour locks reduce levels of braking power, considerably increase braking
distance and can cause the brake system to fail completely.
•Please ensure that the correct brake fluid is used. Only use brake fluid that is explicitly
compliant with VW standard 501 14.
•Any other brake fluid or a low-quality one can affect the functioning of the brakes and
reduce their effectiveness.
•If a brake fluid compliant with VW standard 501 14 is not available, use a high-quality
brake fluid compliant with DIN ISO 4925 CLASS 4 or the US standard FMVSS 116 DOT 4,
but only in exceptional circumstances.
•The refilled brake fluid must be new.
WARNING
Brake fluid is toxic.
•In order to reduce the risk of poisoning, never use bottles or other containers to store
brake fluid. These containers could encourage other people to drink out of them, even if
they are labelled otherwise.
•Brake fluid must always be stored in its original sealed container and kept out of the reach
of children.
WARNING
Brake fluid that has leaked or been spilt can damage the vehicle paintwork, plastic parts and
tyres. Brake fluid that has leaked or been spilt should be cleaned off the vehicle paintwork and
other components immediately.
NOTICE

Avoid unnecessary loads
The lighter the vehicle, the more economical and environmentally-friendly it is. An extra weight of
100 kg can increase fuel consumption by up to 0.3 l/100 km.
Remove all unnecessary objects and loads from the vehicle.
Remove any unnecessary special equipment and accessories
The more aerodynamic a vehicle, the lower its fuel consumption. Special equipment and
accessories, such as roof carriers or bicycle carriers, make the vehicle less aerodynamic.
You should therefore remove any special equipment and luggage carriers that are not in use,
especially if you are going to be driving at high speeds.
Steering
 Introduction
This chapter contains information on the followingsubjects:
⇒ Warning and indicator lamps
⇒ Information on steering
Depending on its equipment level the vehicle may have power steering.
The power steering is not hydraulic. It is an electromechanical system. The advantage of this
steering system is that no hydraulic hoses, hydraulic oil, pumps, filter or other parts are required.
The electromechanical system reduces fuel consumption. A hydraulic system requires constant oil
pressure in the system, whereas an electromechanical steering system only needs an energy
supply while steering.
The power steering provided by the electromechanical steering system automatically adjusts to the
vehicle speed, steering wheel torque and steering wheel angle. The electromechanical steering
only functions when the engine is running.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
When the start/stop system is active, the engine is switched off whenever the vehicle is stationary.
The engine then restarts automatically as soon as it is required.
The function is automatically activated every time the ignition is switched on. The instrument cluster
display shows information about the current status ⇒ Indicator lamps.
Always switch off the start/stop system manually when driving through water.
Vehicles with a manual gearbox
•When the vehicle is stationary, disengage the gear and release the clutch pedal. The engine is
stopped.
The intelligent technology of the pull-away assist systems cannot overcome the laws of
physics. Never let the extra convenience afforded by pull-away assist systems tempt you into
taking any risks when driving – this can cause accidents.
•Unintentional vehicle movements can cause serious injury.
•The pull-away assist systems cannot replace the full concentration of the driver.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
•A pull-away assist system cannot hold the vehicle in all hill start situations or brake it
sufficiently on all slopes going downhill (e.g. if the ground is slippery or icy).
WARNING
Failure to observe the warning lamps could lead to your vehicle breaking down in traffic, and
to accidents and serious injuries.
•Never ignore any warning lamps that are lit up.
•Stop the vehicle as soon as it is possible and safe to do so.
WARNING
Failure to observe the illuminated indicator lamps could lead to the vehicle being damaged.
NOTICE

•If vehicles are travelling towards you in the same lane.
•If the surrounding vehicles are very dirty and therefore not very reflective.
•If there is a lot of dust.

Dust and pollen filter
The dust and pollen filter reduces the level of impurities in the outside air entering the vehicle.
The dust and pollen filter must be changed regularly to avoid impairing the performance of the air
conditioning system.
The dust and pollen filter must be changed more frequently than stated in the service schedule if
the efficiency of the filter declines prematurely due to the vehicle being used in areas with high
levels of air pollution.

If the cooling system is switched off, the outside air that is drawn into the vehicle is not
dehumidified. To prevent the windows misting over, Volkswagen recommends that you leave the air
conditioning (compressor) switched on. Press the button. The indicator lamp in the button
must light up.
Maximum heat output, which is needed to defrost the windows as quickly as possible, is only
available when the engine has reached its operating temperature.
Poor visibility through all windows increases the risk of collisions and accidents, which can
cause serious injuries.
•Always ensure that all windows are free of ice, snow and mist to ensure good visibility.
•Maximum heat output, which is needed to defrost the windows as quickly as possible, is
only available when the engine has reached its operating temperature. Do not start your
journey until you have good visibility.
•Always ensure that the heating and fresh air system or the air conditioning system and the
heated rear window are used correctly in order to have good visibility.
•Never use the air recirculation mode for an extended period. If the cooling system is
switched off, the windows can mist up very quickly in air recirculation mode and reduce
visibility considerably.
•Always switch off the air recirculation mode when it is not required.
WARNING
Stale air can quickly cause tiredness and lack of concentration in the driver, which in turn can
cause collisions, accidents and serious injuries.
•Never switch off the blowers or switch on the air recirculation mode for an extended period
as this prevents fresh air from entering the vehicle interior.
WARNING
•Switch off the air conditioning system if you suspect that it has been damaged. This can
help to prevent further damage. The air conditioning system should be checked by a
qualified workshop.
•Repairs to the air conditioning system require specialist knowledge and special tools.
Volkswagen recommends using a Volkswagen dealership for this purpose.
