Quick Reference Guide
There are three levels of regeneration:
Passive regeneration
Automatic regeneration of the DPF above a certain exhaust temperature. No
intervention required by the driver and no indication on the master display.
Active regeneration
Regeneration when driving, triggered by the engine management system (EMS). No
intervention by the driver required.
NOTE: When at low speed or with the vehicle stationary (during forced
stationary regeneration) the yellow coloured high exhaust system
temperature (HEST) is shown in the instrument panel. Take care that no
people, vehicles, animals or combustible materials are within 2 metres of the
exhaust outlet.
Forced stationary regeneration
When Passive and Active Regeneration is not sufficient the system will prompt that a
forced stationary regeneration is required.
A forced stationary regeneration is performed at stand-still and triggered by the driver.
To prevent the engine derating power, perform regeneration of the DPF as soon as
safely possible.
Four different levels of pop-up messages on the master display are possible to warn
you the DPF must be regenerated stationary.
1. Soot level high. Regeneration required (yellow).
An alternative to overcome this is to take a motorway route which will
clear the soot via passive regeneration.
When ignored, this warning will re-appear at the next key cycles.
2. Soot level too high. Start regeneration immediately (yellow).
Again, to overcome this is to take the motorway route.
