Continuous filter regeneration is impossible
under certain conditions such as low-speed driv-
ing. Under these conditions, the system auto-
matically raises the exhaust temperature to burn
the PM to regenerate the filter (automatic DPF
regeneration). However, even automatic DPF
regeneration is sometimes impossible if the
vehicle is repeatedly driven very slowly and the
engine is frequently started and stopped. The
DPF must then be regenerated by burning the
PM under manual control (parked DPF regener-
ation).

The BlueTec
®
exhaust gas aftertreatment
reduces nitrogen oxides (NOx) by adding
(spraying) AdBlue
®
(urea) to an area upstream
of the selective catalytic reduction (SCR) cata-
lyst to decompose NOx into water and nitrogen.

DPF stands for Diesel Particulate Filter.
•
SCR stands for Selective Catalytic Reduction.
•
The urea tank and urea tube are provided with a
heater to thaw AdBlue
®
(urea) and keep it warm
in cold weather.
•
When the AdBlue
®
(urea) temperature is low,
the idling speed may slightly increase. When the
AdBlue
®
(urea) becomes warm, the idling speed
returns to normal.
