WARNING
• Please pay attention to the traffic regulations and speed limits.
• The diesel particle filter achieves very high temperatures.
Therefore do not park at points where the hot filter comes into
direct contact with dry grass or other combustible materials - risk
of fire!
• Use neither protective paint for chassis nor anti-corrosion
agent, in order to treat the exhaust system, the heat shields or the
diesel particle filter. The high temperatures can cause the coating
to ignite!
Note
• It is prohibited to use biofuel (RME) and diesel fuel mixture for diesel
vehicles which are fitted with diesel particle filter.
• When using diesel fuel with high sulphur content the life of the diesel
particle filter is clearly reduced. A specialist garage will be able to tell you
which countries offer only diesel fuel with high sulphur content.
