Where vehicle use meets any of the
following conditions:
• Driving short distances.
• Prolonged engine idling.
• Frequently switching the engine on and
off.
• High levels of acceleration and
deceleration.
We recommend you assist the
regeneration process by:
• Avoiding prolonged engine idling.
• Drive your vehicle in a manner to allow
effective cleaning. Drive at a steady
vehicle speed of 30 mph (48 km/h) or
above for approximately 20 minutes.
If the warning lamp illuminates
the diesel particulate filter could
have become overloaded. Have
your vehicle checked as soon as possible.
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 30 mph (48 km/h) 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 100 mi
(160 km) and 310 mi (500 km) 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.
Diesel Particulate Filter Manual
Regeneration (If Equipped)
WARNING: Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard.
WARNING: The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter or the diesel
