First read and observe the introductoryinformation and safety warnings⇒
Introduction
The tank filler neck in diesel vehicles can be fitted with a misfuelling prevention device ⇒ Fig. 196.
The misfuelling prevention device ensures that the vehicle can be refuelled only using diesel pump
nozzles.
Turn the diesel nozzle to and fro if the misfuelling prevention device gets stuck. This can open the
misfuelling prevention device and make it possible to refuel the vehicle. If the misfuelling prevention
device remains closed, proceed to a qualified workshop to have the system checked.
If it is necessary to refuel the vehicle using a spare fuel canister in the event of an emergency, the
misfuelling prevention device will not open. In order to fill the tank with fuel, pour the diesel into the
tank extremely slowly in very small quantities.

AdBlue is a registered trademark and is also known as AUS32 or DEF (Diesel Exhaust Fluidyf .
The AdBlue consumption figures depend on the driving style, the operating temperature and the
ambient temperature. The remaining range and refill quantity can be checked on the instrument
cluster display.
The AdBlue tank must never run empty. As of a remaining distance of approximately 2,400 km,
the instrument cluster display will indicate that the AdBlue must be refilled ⇒ Troubleshooting.
Preparing to refill
•Stop vehicle on a level surface.
•Switch off the ignition.
•Only use AdBlue that complies with the standard ISO 22241-1 ⇒.
Opening the tank filler neck
•Open the tank flap.
Engine emissions contain carbon monoxide that can cause people to lose consciousness
and can also cause death.
•Never start or run the engine in closed spaces.
•Never leave the engine running if you leave the vehicle unattended.
WARNING
The components of the exhaust system become very hot. This can cause fires.
•Park the vehicle so that no part of the exhaust system can come into contact with any
inflammable material underneath the vehicle, e.g. dry grass.
•Never apply additional underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converters, particulate filter or heat shields.

The refill bottle must be disposed of in accordance with regulations governing the protection
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.
