174 Intelligent Technology
If the diesel particle filter is clogged or there is a fault, it is indicated by the warning light
 .
WARNING

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!

Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converters, diesel particle filter or heat shields.
When the engine reaches its operating temperature, these substances might
ignite - risk of fire.
Note

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 use only
diesel fuel with high sulphur content.
