of the environment.
Catalytic converter
First read and observe the introductoryinformation and safety warnings⇒
Introduction
To help ensure long-term functionality in the exhaust system and the catalytic converter:
•Use unleaded petrol only ⇒ Fuel types and refuelling.
•Do not allow the fuel tank to run completely empty.
•Do not overfill engine oil ⇒ Engine oil.
•Do not tow start the vehicle. Use jump leads ⇒ Jump starting.
If you notice misfiring, uneven running or loss of power when the vehicle is moving, reduce speed
immediately. The vehicle should be inspected at the nearest qualified workshop
⇒ Troubleshooting. If this happens, unburnt fuel can enter the exhaust system and escape into the
atmosphere. The catalytic converter can also be damaged by overheating.
The emissions may have a sulphur-like smell even if the emission purification system is
working properly.
Particulate filter
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Function
The particulate filter filters out soot particles in the exhaust gas. Observe the following points to
ensure that the exhaust purification system will work properly for a long time:
AdBlue is an irritant and corrosive fluid that can damage the skin, eyes and breathing
passages upon contact.
•Always observe the instructions for use when using AdBlue. If containers are used
according to the instructions, it is unlikely that a user will come into contact with
AdBlue.
•AdBlue must be kept in the closed original container. Never use empty food
containers, bottles or other containers for this purpose.
•Always store in a safe place out of reach of children.
•If AdBlue gets into the eyes, immediately rinse the eyes with plenty of water for at
least 15 minutes and consult a doctor.
•If AdBlue gets onto the skin, immediately wash the area with plenty of water for at
least 15 minutes and consult a doctor if the skin becomes irritated.
•If AdBlue is swallowed, immediately rinse the mouth out with lots of water for at least
15 minutes. Do not induce vomiting unless instructed to do so by a doctor. Seek
medical assistance immediately.

Engine coolant
Introduction
This chapter contains information on the followingsubjects:
⇒ Coolant specification
⇒ Checking the coolant level and refilling coolant
You should only carry out work on the cooling system if you know exactly how to perform the
required tasks, are aware of the general safety procedures and have access to the correct
equipment, service fluids and suitable tools. Failing to carry out work correctly can cause serious
injuries ⇒. The work should be carried out by a qualified workshop if you are uncertain.
Volkswagen recommends using a Volkswagen dealership for this purpose.
Coolant and coolant additives can pollute the environment. Spilt service fluids must be
collected then disposed of properly and in an environmentally responsible way.
Coolant specification
First read and observe the introductoryinformation and safety warnings⇒

Engine coolant is toxic.
•Engine coolant should only be kept in sealed original containers in a safe place.
•Never store engine coolant in empty food containers, bottles or any other non-original
containers as people finding these containers may then drink the engine coolant.
•The engine coolant must be stored out of the reach of children.
•Please note that the amount of correct coolant additive used must be sufficient for the
lowest ambient temperature that you expect the vehicle to be exposed to.
•Coolant can freeze at extremely cold outside temperatures, causing the vehicle to
break down. Vehicle occupants with inadequate winter clothing could then freeze to
death as the heating will also no longer function.
WARNING

Mobile communication in the vehicle
Electromagnetic radiation
If a mobile telephone or radio device is used without being connected to the external aerial, the
electromagnetic radiation will not be optimally directed to the outside of the vehicle. Increased
levels of radiation in the vehicle interior can occur in particular in the event of poor reception, e.g. in
rural areas. This could constitute a health hazard ⇒.
Depending on the equipment, you may be able to use a suitable mobile phone interface to connect
the mobile telephone to the external aerial ⇒BookletInfotainment system,. The connection quality is
improved and the range of the mobile communication device is increased.
Using a telephone
Many countries require a hands-free system to be used when using a telephone inside the vehicle,
e.g. via a Bluetooth connection. Before use, secure the mobile telephone to a suitable bracket ⇒
or stow it in a storage compartment so that it cannot slip around, e.g. in the centre console.
Use a compatible mobile telephone if the mobile phone interface uses the remote SIM Access
Profile (rSAPyf technology.
Two-way radios
Observe legal regulations and the manufacturer's operating instructions for operation of two-way
radios. Approval is required for retrofitting two-way radio systems.
Ask your Volkswagen dealership for further information on installation of two-way radio systems.
Customer information
Incorrect repairs and modifications can cause malfunctions and damage to the vehicle
and impair the effectiveness of the airbag system. This can result in accidents and serious
or even fatal injuries.
•Repairs and modifications to your vehicle should only be carried out by a qualified
workshop.
•Airbag modules cannot be repaired. They must be replaced.
•Never use recycled airbag components or components that have been taken from end-
of-life vehicles in your vehicle.
WARNING
Modifications to the vehicle's suspension, including the use of unsuitable tyre/rim
combinations, can cause the airbag system to work differently and increase the risk of
serious or fatal injuries in the event of an accident.
•Never install any components in the suspension system that do not have the same
characteristics as the original factory-fitted components.
•Never use tyre/rim combinations that have not been approved by Volkswagen.
WARNING
®
Mobile telephones which are loosely placed in the vehicle or not properly secured could
be flung through the vehicle interior and cause injuries during a sudden driving or braking
manoeuvre, or in the event of an accident.
•Secure any mobile telephones and accessories located beyond the deployment zone of
the airbags, or stow them safely.
WARNING
If mobile telephones or two-way radios that are not connected to an external aerial are
used, electromagnetic radiation in the vehicle could exceed limit values and thus be a
health hazard for drivers and other vehicle occupants. This also applies to external aerials
which have not been correctly installed.
•Keep a distance of at least 20 cm between a device's aerial and an active medical
implant, e.g. a pacemaker.
•Do not carry an operational device close to or directly above an active medical implant,
e.g. in a breast pocket.
•Switch off the device immediately if you suspect it may be interfering with an active
medical implant or any other medical device.
