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.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
Function

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

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.

Washer fluid
Fig. 226 In the engine compartment: cap of washer fluid reservoir.
The windscreen washer fluid level should be checked regularly and topped up as necessary.
A filter can be found in the feed throat of the washer fluid reservoir. The filter keeps large dirt
particles away from the windscreen washer jets when refilling. The filter should only be removed for
cleaning. If the filter is damaged or is not present, dirt particles can enter the system and will block
the washer jets.
•Open the bonnet ⇒ In the engine compartment.
•The washer fluid reservoir is identified by the symbol on the cap ⇒ Fig. 226.
•Check whether there is enough windscreen washer fluid in the reservoir.
•To top up, mix clean water (not distilled water) with a washer fluid recommended by
Volkswagen ⇒. Observe the dilution instructions on the packaging.
•At low temperatures, add a special anti-freeze agent so that the fluid cannot freeze ⇒.
Capacities
The washer fluid reservoir has a capacity of between 3 and 5 litres depending on the vehicle
equipment level.
Unsuitable service fluids and consumables, and the incorrect use of these fluids and
consumables, can cause accidents, serious injuries, burns or poisoning.
•Service fluids must be kept in their original sealed container.
•Never store service fluids in empty food containers, bottles or any other non-original
containers as people finding these containers could drink them.
•Keep children away from all service fluids and consumables.
•Always read and follow the information and warnings on the service fluid packaging.
•When using products that give off harmful fumes, always work outdoors or in a well-
ventilated area.

explosions.
WARNING
•Only use suitable service fluids for refilling. Never use the wrong service fluid. Failure
to observe this warning can result in serious malfunctions and engine damage.
•Optional equipment and other accessories in front of the air inlet reduce the cooling
effect of the coolant. The engine may overheat at high ambient temperatures and high
engine loads.
