necessary.
The "Automatic regeneration" mode is preset when the engine is started.
Diesel particulate filter regeneration is only started when the engine is at
operating temperature.
If the diesel particulate filter reaches a certain soot load, an automatic re-
generation is triggered. The control light illuminates during the regenera-
tion
.
The vehicle can be operated without restriction during automatic regener-
ation as long as there are no easily flammable materials in the immediate
vicinity. If an automatic regeneration is triggered while the vehicle is in the
immediate vicinity of easily inflammable materials, the regeneration must
be interrupted manually with the switch.
Regeneration stops if it is interrupted manually, or if the starting key is
moved to position0 during regeneration. This has the effect that the soot
particles are not removed from the diesel particulate filter. The sub-
sequent regeneration lasts longer due to the increased soot load. Regen-
eration takes about 30 minutes. If is regeneration started, the engine
must run until regeneration is over, even if work with the vehicle is fin-
ished before.

Interrupting automatic regeneration manually
In exceptional cases, regeneration can be interrupted with switch 1. The
switch is located on the instrument panel. The switch has three switch po-
sitions.
• Switching stage 0 = Switch in neutral position
• Switching position I = Interrupts regeneration
• Switching position II = Triggers manual regeneration.
Suppressing regeneration
▪ Hold the switch in position I for at least three seconds.

ð Regeneration is interrupted.
If a regeneration has been interrupted manually, the following options are
available.
• Manual regeneration can be triggered.
• After restarting the engine, an automatic regeneration is triggered
again as soon as the engine has reached the required temperature.
Consequences of an interruption
If a regeneration is interrupted manually or the ignition is switched off, the
regeneration stops. This means that the soot load cannot be removed
from the diesel particulate filter. The subsequent regeneration lasts
longer due to the increased soot load.
