Operation
Diesel engine
Zone 0
Particle filter passive regeneration.
No action required.
DPF is always protected by passive regeneration when the diesel engine is running.
Zone 1
The active automatic regeneration of the DPF is
on. Warning indicator lights up to inform the driver.
No action required.
An automatic regeneration may start while driving, loading or in a standby mode. The
automatic regeneration only starts when all operating conditions are met, such as
sufficiently high engine oil and exhaust gas temperatures. If one of the operating con-
ditions is no longer fulfilled during regeneration, the indicator light goes out. Please
note, that temperatures similar to those of full load can occur at the exhaust gas out-
let even at low power requirements of the diesel engine or when the engine is at a
standstill.
ADVICE
Under normal operating conditions, it occurs approx. every 35 hours of operation.
If possible, please do not interrupt regeneration (do not switch off the diesel engine if
that is possible). However, the interruption is not harmful.
Zone 2
Particle filter filling level high, initiate manual
regeneration immediately. Warning indicators are
on.
Action required within the next 1-2 hours.
Carry out high idle regeneration at a standstill in the "Special functions" menu, "Start
DPF regeneration manually" line (See Page 182). Press "On", the idle speed
increases at the start of regeneration, which lasts between 30 and 60 minutes.
ADVICE
This advice applies to Zone 2, Zone 3 and Zone 4.
The vehicle operating profile is not sufficient for automatic regeneration (too low load
requirement, too frequent interruptions).
If the indicator requests you to perform a manual regeneration at low outside temper-
atures, start the regeneration before you switch off the diesel engine.
The manual regeneration only starts if the following conditions are met:
•
Engine oil and exhaust gas temperature is sufficiently high.
•
AdBlue® (DEF) is not frozen.
•
System without malfunctions.
