Mercedes-Benz TRAVEGO, Operating Instructions Manual

Operation
Diesel particulate filter regeneration
Note:
The LED in the “Inhibit regeneration”
pushbutton comes on and no regenera-
tion can be started.
Caution:
Leave the regeneration inhibitor activated
only for as long as the danger exists.
Whenever you activate the regeneration
inhibitor, regeneration will continue to be
inhibited even after the next engine start.
Note:
There would otherwise be a risk of rap-
id loading of the diesel particulate filter.
In this event, the on-board computer re-
minds you with a grey “Regeneration in-
hibited” event window that the regenera-
tion inhibitor is still active.
M54.00-2233-71
To deactivate, press the lower section of
inhibit pushbutton (1) again.
Note:
The LED in the pushbutton goes out.
Catalytic converter protection
function
In very rare cases (e.g. frequent low
load operation with relatively low exhaust
temperatures), unburnt fuel could col-
lect in the exhaust system. The exhaust
system could suffer damage as a result.
To prevent this, the engine speed is
automatically increased for approxim-
ately 20 to 30 minutes by the exhaust
gas aftertreatment control module under
specific circumstances. This raises the
exhaust temperature and burns off the
fuel.
Note:
This function can only be started with the
vehicle parked (parking brake engaged)
and the engine idling.
Note:
A corresponding message appears on the
display screen to indicate that the catalyt-
ic converter protection function is active.
Note:
It is possible to interrupt this function by
switching off the engine, engaging a gear
or releasing the parking brake.
