Diesel particle filter (diesel engine) If the warning light
comes on, this means that soot has accumulated in the
diesel particle filter because of the frequent short distances.
In order to clean the diesel particulate filter, the vehicle should be driven at an
even speed of at least 60 km/h at engine speeds of 1
800 - 2 500 rpm for at least
15 minutes or until the warning light goes out with the 4th or 5th gear engaged
(automatic gearbox: position S) when the traffic situation permits it. This increa-
ses the exhaust temperature and the soot deposited in the diesel particle filter is
burnt.
Always pay attention to the valid speed limits ⇒ .
The warning light goes out after the successful cleaning of the diesel particle
filter.
If the filter is not properly cleaned, the warning light does not go out and the
warning light begins to flash. The following is displayed in the information dis-
play: Diesel-particle filter: Owner's manual! appears. Afterwards the engine con-
trol unit shifts the engine into the emergency mode, which only has a reduced
power output. After switching the ignition off and on again the warning light
comes on.
Have the vehicle inspected without delay by your specialist garage. WARNING

sponding descriptions and warning notes, this may result in injuries or major
