The ESC or the TCS/TC can only function properly if all four wheels have the same tyres.
Any differences in the rolling radius of the tyres can cause the system to reduce engine power
unexpectedly.
If the ABS fails, the ESC, TCS, TC and EDL will also cease to function.
Control processes running in the systems described may cause operating noises.
Brake fluid
Fig. 101 In the engine compartment: cap on the brake fluid container
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Brake fluid will gradually absorb water from the surrounding air. The brake system will be damaged
if there is too much water in the brake fluid. The boiling point of the brake fluid is also considerably
reduced by the water content. Heavy use of the brakes may cause a vapour lock in the brake
system if the water content is too high. Vapour locks reduce levels of braking power, considerably
increase braking distance and can even cause the brake system to fail completely. Your own safety
and that of other road users depends on having a brake system that functions properly at all times
⇒.
Brake fluid specification
Volkswagen has developed a brake fluid that has been optimised for the brake system in the
vehicle. To ensure optimal operation of the brake system, Volkswagen recommends the use of
brake fluid compliant with VW standard 501 14.
Driving fast on icy, slippery or wet roads can lead to a loss of control of the vehicle and could
cause serious injury to the driver and passengers.
•Adapt your speed and driving style to suit visibility, weather, road and traffic conditions. Do
not let the extra safety afforded by the brake assist systems ABS, BAS, EDL, TCS, TC and
ESC tempt you into taking any risks when driving.
•The brake assist systems cannot defy the laws of motion. Slippery and wet roads will
remain dangerous, even when the ESC and other systems are active.
•Driving too fast on wet roads can cause the wheels to lose contact with the road surface
and aquaplane. A vehicle cannot be braked, steered or controlled once it has lost contact
with the road surface.
•Brake assist systems cannot prevent an accident if, for example, you are driving too close
to the vehicle in front or are driving too fast for the individual situation.
•Although the brake assist systems are very effective and can help to control the vehicle in
difficult driving situations, please always remember that the driving stability of the vehicle
depends on the tyre grip.
•When accelerating on a slippery surface, for example on ice and snow, press the
accelerator carefully. The wheels can spin even with active brake assist systems and this
can lead to a loss of control of the vehicle.
WARNING
ESC will be considerably less effective if other components and systems that affect driving
dynamics are not serviced correctly or are not functioning properly. This also applies, but not
exclusively, to the brakes, tyres and other systems that have already been named.
•Please always note that modifications and changes to the vehicle can affect the function of
the ABS, BAS, TCS, TC, EDL and ESC.
•Alterations to the suspension system or the use of non-approved wheel and tyre
combinations can affect the function of ABS, BAS, TCS, TC, EDL and ESC and reduce
their effectiveness.
•Suitable tyres are also crucial if ESC is to function optimally ⇒ Wheels and tyres.
WARNING

•The cooling function of the air conditioning system: if the air conditioning system is set to a very
high or low temperature it will require a lot of energy, which is generated by the engine.
Therefore the temperature setting in the vehicle should not vary too much from the outside
temperature. It may be a good idea to air the vehicle before setting off and then to travel a short
distance with the windows open. The air conditioning system should then be switched on once
the windows have been closed.
•Keep the windows closed when driving at high speeds. Having the windows open increases fuel
consumption.
•Switch the seat heating off as soon as it has served its purpose.
•Switch the rear window heating off as soon as the window has defogged and is clear of ice.
Other factors that increase fuel consumption (examples):
•Fault in engine management.
•Driving in hilly regions.
Driving in a fuel-efficient manner
Fig. 102 Fuel consumption in litres per 100 km at two different outside temperatures
First read and observe the introductoryinformation and safety warnings⇒
Introduction
By adopting an economical driving style and anticipating the traffic situation ahead, you can easily
reduce fuel consumption by 10-15 %.
Cars use most fuel when accelerating. If you think ahead when driving, you will need to brake less
and thus accelerate less. Wherever possible, let the car roll slowly to a stop, for instance when you
can see that the next traffic lights are red.
Avoid short journeys
Directly after a cold start, the engine has a very high fuel consumption. The engine reaches its
working temperature after a few kilometres, when fuel consumption will return to a normal level.
The engine and catalytic converter need to reach their proper working temperature in order to
minimise fuel consumption and emissions. The outside temperature is a key factor.
The different rates of fuel consumption for the same distance at both +20°C (+68°F) and at -
10°C (+14°F) are shown in ⇒ Fig. 102.
Therefore, avoid making too many short journeys and car share whenever possible.
Under the same conditions, the vehicle will use more fuel in winter than in summer.
Not only is it illegal in some countries to warm up the cold engine by running it while the vehicle is
stationary, it is also technically unnecessary and a waste of fuel.
Adjust the tyre pressure
The correct tyre pressure reduces rolling resistance and therefore also fuel consumption.
Ensure that any new tyres purchased have optimum rolling resistance.
Using low viscosity engine oils
Fully synthetic low viscosity engine oils reduce fuel consumption. Low viscosity engine oils
decrease frictional resistance in the engine and spread better and more quickly, especially for cold
starts. They are especially effective in vehicles that make a lot of short journeys.
Always ensure that the engine oil level is correct and that you keep to the service intervals (oil
change intervals).
When buying engine oil, always ensure that it complies with engine oil norms and has been
approved by Volkswagen.

ParkPilot
Introduction
This chapter contains information on the followingsubjects:
⇒ Operating ParkPilot
⇒ Acoustic and optical ParkPilot signals at the rear of the vehicle
The ParkPilot assists the driver when manoeuvring and parking.
The ultrasound sensors in the rear bumper transmit and receive ultrasonic waves. The system uses
the time difference between the ultrasonic waves (i.e. between the transmission and reflection from
obstacles and the point of reception) to continuously calculate the distance between the bumper
and the obstacle.

Cruise control system (CCS)
Introduction
This chapter contains information on the followingsubjects:
⇒ Indicator lamp
⇒ Using the cruise control system (CCS)
The cruise control system (CCS) helps to maintain a specific preset speed during forward travel at
approx. 20 km/h (15 mph) and higher.
The CCS only slows the vehicle by easing off the accelerator, not by actively braking ⇒.

Introduction
Lit upPossible cause
Cruise control system (CCS) is controlling the speed.
Several warning and indicator lamps will light up briefly as a functional check when the ignition is
switched on. They will switch off after a few seconds.
Using the cruise control system (CCS)
The use of the cruise control system can lead to accidents and serious injuries if traffic does
not allow you to drive at a safe distance from the vehicle in front at a constant speed.
•Never use the CCS in heavy traffic, on steep or winding roads, or on slippery road
surfaces e.g. on snow, ice, wet roads, loose chippings, or on flooded roads.
•Never use the CCS when driving off-road or on unsurfaced roads.
•Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and
traffic conditions.
•Always switch cruise control off after use to avoid unintentional operation.
•It is dangerous to use a set speed that is too high for the prevailing road, traffic or weather
conditions.
•The CCS cannot maintain a constant speed when travelling downhill. The vehicle speed
can increase under its own weight. Shift down a gear or brake the vehicle using the foot
brake.
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.
WARNING
Failure to observe the illuminated indicator lamps could lead to the vehicle being damaged.
NOTICE

If, in a potential collision scenario, the city emergency brake function detects that the driver is
applying the brakes with insufficient pressure, the system can increase the brake pressure in order
to reduce speed ahead of the collision. Hence the system can help minimise the consequences of
an accident.

The brake pedal travel decreases when the city emergency brake function is triggered. This
may make the brake pedal feel stiffer.
Automatic brake intervention by the city emergency brake function can be stopped by using
the clutch, the accelerator or steering intervention.
Unusual noises may be heard if the city emergency brake function is applying an automatic
braking procedure. This is normal and the noises are caused by the braking system.
Warning and indicator lamps
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The city emergency brake function is switched on every time the ignition is switched on. No display
will be shown to alert you of this.
The indicator lamp will be lit up if the city emergency brake function is switched off, is working or if
there is a fault in the system.

necessary, inspect the laser sensor (for
The intelligent technology of the city emergency brake function cannot change the laws of
physics or the system-related vehicle limitations. Never let the extra convenience afforded by
the city emergency brake function tempt you into taking any risks when driving. The driver is
always responsible for braking in time.
•The city emergency brake function cannot prevent accidents and serious injuries by itself.
•The city emergency brake function can carry out unwanted brake interventions in certain
complex situations, e.g. if a vehicle cuts very closely in front of you.
WARNING
Incorporating the city emergency brake function into your own driving style can cause
accidents and serious injuries. The system is not a substitute for the full concentration of the
driver.
•Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and
traffic conditions.
•The city emergency brake function does not react to persons, animals and vehicles
crossing or approaching in the same lane.
•Brake the vehicle by depressing the brake if the vehicle rolls forwards once the city
emergency brake function has been applied.
WARNING
Switch off the city emergency brake function if you suspect that the laser sensor has been
damaged. This can help to prevent further damage.
•Repairs to the laser sensor require specialist knowledge. Volkswagen recommends using
a Volkswagen dealership for this purpose.

Special driving situations
Fig. 110 A: vehicle in a bend B: motorbike in front is outside the range of the laser sensor
Fig. 111 Vehicles changing lanes
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The city emergency brake function has physical and system-specific limits. In certain situations, the
driver may therefore feel that the city emergency brake function reacts too late or unexpectedly.
You should therefore always be prepared to take full control of the vehicle if necessary.
The following driving situations demand particular vigilance:
When driving through bends
When driving into or out of a long bend, the laser sensor may react to a vehicle in the adjacent lane
⇒ Fig. 110A and thus brake the vehicle. The braking effect can be stopped by pressing the
accelerator or clutch pedal or by steering the vehicle.
Narrow vehicles and a zig-zag traffic situation
Narrow vehicles and vehicles travelling slightly to the left or right of your vehicle will only be
recognised by the laser sensor once they have entered the range of the sensor ⇒ Fig. 110B. This
particularly applies to narrow vehicles such as motorcycles.
When other vehicles change lanes
Vehicles that are very close to you when they move into your lane could cause the city emergency
brake function to be applied unexpectedly ⇒ Fig. 111. The braking effect can be stopped by
pressing the accelerator or clutch pedal or by steering the vehicle.
Possible laser sensor function impairments
The city emergency brake function will switch off temporarily if the function of the laser sensor is
impaired due to heavy rain, spray, snow or mud, for example. The indicator lamp will flash in
the instrument cluster display.
The city emergency brake function is ready to work again as soon as the laser sensor returns to
normal function. The indicator lamp goes out.
The following conditions could prevent the city emergency brake function
from reacting:
•If ESC is active.
•In tight bends.
•If the vehicle is reversing.
•When you drive faster than 30 km/h for a few seconds.
•If the accelerator is fully depressed.
•If the city emergency brake function is switched off or if there is a fault in the system ⇒ Warning
and indicator lamps.
•If the laser sensor is dirty, covered or overheated ⇒ Laser sensor.
•In snow, heavy rain or thick fog.
•If vehicles are travelling slightly to the left or right of your vehicle.
•If vehicles are crossing in front of your vehicle.
Accidents and serious injuries could occur if you do not switch off the city emergency brake
function during any of the situations named above.
•Switch off the city emergency brake function during critical driving situations.
WARNING

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.

General information on the heating and fresh air system
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The required interior temperature cannot be lower than the outside temperature as the heating and
fresh air system cannot cool or dehumidify the air.
Settings for optimal road visibility
•Set blower ⇒ Fig. 112② to level 1 or 2.
•Open and position all vents on the dash panel ⇒ Vents.
•Turn the air distribution controller ⇒ Fig. 112③ to the defrost position.
Information on the air conditioning system
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The cooling system for the vehicle interior only works when the engine is running and the blower is
switched on.
The air conditioning system operates most effectively with the windows and the electric panorama
sliding and tilting glass roof closed. However, if the vehicle has heated up after standing in the sun
for some time, the air inside can be cooled more quickly by opening the windows and the electric
panorama sliding and tilting glass roof for a short time.
Settings for optimal road visibility
Switching the cooling system on not only reduces the temperature of the vehicle interior, but also
the humidity. This improves comfort for the vehicle occupants and prevents the windows from
misting when the outside humidity is high.
•Switch off air recirculation mode ⇒ Air recirculation mode.
•Set the blowers to the required level.
•Open and position all vents on the dash panel ⇒ Vents.
•Turn the air distribution controller to the defrost position.
•Press the button to switch the cooling system on. The indicator lamp in the button
lights up.
The cooling system cannot be switched on
The following criteria may prevent the cooling system from being switched on:
•The engine is not running.
•The blower is switched off.
•The air conditioning system fuse has blown.
•The ambient temperature is lower than approximately +2℃ (+36°F).
•The compressor has been temporarily switched off because the coolant temperature is too high.
•There is a different fault in the vehicle. The air conditioning system should be checked by a
qualified workshop.
Things to note
If the humidity and temperature outside the vehicle are high, condensation can drip off the
evaporator in the cooling system and form a pool underneath the vehicle. This is normal and does
not indicate a leak.
The windscreen may mist up after starting the engine due to residual humidity in the air
conditioning system. Switch the defrost function on in order to clear the windscreen of condensation
or mist as quickly as possible.
