WARNING
The parts of the exhaust system become very hot and can ignite flammable materials, for example shrubs, leaves, dry
grass or spilled fuel. This can lead to a fire and cause accidents and serious or fatal injuries.
Never park the vehicle in such a way so that the exhaust system components come into contact with flammable
materials under the vehicle.
Never use additional undercoating or corrosion protection for exhaust pipes, catalytic converters, heat shields, or
particulate filters.

and
Safety precautions for
To ensure that the exhaust system and the engine catalytic converter can work correctly for a long time, observe the following
Only refuel with fuel permitted for the vehicle.
Never drive until the fuel tank is completely empty.
Never add too much engine oil ⇒ Checking the engine oil level and adding oil .
Do not tow-start the vehicle; use jump-start assistance instead ⇒ Start the engine.
If there are engine misfires, loss of power, or poor engine operation while driving, reduce the speed immediately and have the
vehicle checked by suitably qualified professionals ⇒ Troubleshooting. Volkswagen recommends contacting an authorized
Volkswagen dealer or authorized Volkswagen Service Facility. Otherwise, uncombusted fuel could be present in the exhaust
system and then enter the atmosphere. The catalytic converter may also be damaged from overheating.
The exhaust may smell like sulfur when the emissions control system is running correctly.

Safety precautions for
Function
The particulate filter depends on the vehicle equipment and filters out soot from the exhaust gas.
Regeneration
With normal vehicle usage, the filter cleans itself. If the filter is unable to clean itself, e.g. if you only make short trips for an
extended period of time, the filter can become blocked with soot. The particulate filter needs to be cleaned (regenerated).
Noises, light odors, and increased engine speeds may occur during the regeneration. The radiator fan may continue to run
while driving and after turning off the engine.
To assist in particulate filter regeneration, Volkswagen recommends avoiding driving short distances too frequently.
The soot in the particulate filter is burned periodically at high temperatures. The yellow
