Misfiring, which damages the catalytic con-vert er.
Several warning and indicator lamps will light up briefly as a functional check when the ignition is switched on. They will go out after a few seconds.
A WARNING
Please observe legal requirements If cleaning the diesel particulate filter when in traffic.
• Follow driving recommendation only if visibility, weather, road and traffic conditions are suitable.
• Do not endanger other vehicles on the road.
A WARNING
The exhaust fumes contain carbon monoxide, an odourless and colourless toxic gas. Car-bon monoxide can cause people to lose con-sclousness. lt can also cause death.
• Never start or run the engine In unventlla-ted or closed spaces.
• Never leave the engine running If you leave the vehicle unattended.

Diesel particulate filter
r-f'n First read and observe the Introductory L-J,:,.IJ Information and safety warnings & on page 407.
The diesel particulate filter filters out soot particles in the exhaust gas. The soot particles gather in the filter and are burnt under high temperatures peri-odically (regeneration). Heat produced can warm the engine.
Regeneration can cause noises, light smells and delay in radiator fan irrespective of the outside temperature, even after the engine is switched off.
To assist the regeneration of diesel particle filter, Volkswagen recommends that you avoid making only short journeys. In vehicles with a DSG® dual clutch gearbox the engine speed can increase while the vehicle is being driven. However, the indi-cator lamp • will not light up.
Observe the following points to ensure that the ex-haust system and the diesel particulate filter will work properly for a long time:
the nearest qualified workshop. If this happens, un-bumt fuel can enter the exhaust system and es-cape into the atmosphere. The catalytic converter can also be damaged by overheating.
Even when the exhaust purification system is W working perfectly, there may be a smell of sulphur from the exhaust in some conditions. This depends on the sulphur content of the fuel being used. <1
• Only use diesel with low sulphur levels 343.
• Never use biodiesel, petrol or heating oil.
• Do not allow the fuel tank to run empty.
• Do not overfill engine oil 353.
• Do not tow-start the vehicle. Use jump leads =page 443.

Adapter for the anti-theft wheel bolts. Volkswagen Commercial Vehicles recommends you carry the wheel bolt adapter in the vehicle tool kit at all times. The code number of the anti-theft wheel bolt is stamped on the front of the adapter. You will need this num-ber to replace the adapter if lost. Make a note of the code number for the anti-theft wheel bolt and keep it in a safe place-but not inside the vehicle.
