particles. During cleaning, soot particles
are converted to harmless gasses. Once
cleaned, the diesel particulate filter
continues to trap harmful diesel particles.
The warning lamp continues to illuminate
until the automatic regeneration process
completes. Continue to drive your vehicle
in a manner to allow effective diesel
particulate filter cleaning until the warning
lamp turns off.
Failure to carry out regeneration when
required could result in a clogged diesel
particulate filter. If the diesel particulate
filter fills beyond the regeneration
threshold, the system disables the ability
to carry out regeneration. This could result
in damage not covered by the vehicle
warranty.
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.
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.
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.
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 48 km/h (30 mph) or
above for approximately 20 minutes.
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.
