Diesel particulate filter

Please first read and note the introductory information and heed the WARNINGS
The diesel particulate filter helps take soot particles out of the exhaust. The soot particles are collected
and burned in the filter. Volkswagen recommends frequently driving longer distances to help clean the
filter.
Use only Ultra Low Sulphur Diesel (ULSD) fuel No. 2.
Never refuel with gasoline or fuel oil or biodiesel that does not comply with the special
requirements for diesel fuel.
Do not exceed the correct oil level.
Do not tow the vehicle to start, but use a jump-start instead.
On vehicles with automatic transmissions, increase the engine speed slightly while driving to
automatically start cleaning the diesel particulate filter. This helps to minimize clogging of the filter. The
indicator light will not come on.
