If the soot load in the diesel
particulate filter reaches a
critical level, the malfunction
indicator lamp illuminates with the diesel
particulate filter warning message. A
service regeneration must be performed
to recover the particulate filter. Have your
vehicle checked as soon as possible to
prevent further damage.
Automatic regeneration raises the exhaust
temperature to eliminate the soot
particles. During cleaning, soot particles
are converted to harmless gasses. Once
cleaned, the diesel particulate filter
continues to trap harmful diesel particles.
If you are driving your vehicle in a manner
that allows effective cleaning, a message
may appear in the information display to
indicate automatic regeneration is in
progress.
If you are not driving your vehicle in a
manner that allows effective cleaning, a
message may appear in the information
display to instruct you to drive in a manner
that allows automatic regeneration.
The automatic regeneration process is
most effective when you drive at a steady
vehicle speed of 48 km/h (30 mph) or
above for approximately 20 minutes. The
frequency and duration of the regeneration
process varies by how you drive your
vehicle, the outside air temperature and
altitude. Frequency varies between 160 km
(100 mi) and 500 km (310 mi) and each
regeneration process lasts between 10 and
20 minutes.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
Note: During regeneration at low speed or
engine idle, you could smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to the high temperatures
reached during the regeneration process.
This is normal.
