The Diesel particulate filter (DPF) is an integral part of the vehicle
exhaust gas emission reduction systems and it removes the soot
from (Particulate matter) the exhaust gas. Unlike a disposable air
filter, the DPF is regenerative filter. Regeneration is triggered
automatically according to the driving conditions which burns of the
accumulated particles/soot. In other words, the active burning by
engine control system and high exhaust gas temperature caused
by normal/high driving condition burns and removes the
accumulated soot. The process is called as
DDPPFF AAccttiivvee
RReeggeenneerraattiioonn
.
However, if the vehicle continues to be driven at either of the
following conditions the accumulated soot may not be automatically
removed because of low exhaust gas temperature.
1. Heavy traffic driving conditions, especially in city
2. Frequent short trips
3. Low speed for a long time
When more than a certain amount of soot deposited,
the DPF lamp illuminates.
If the DPF lamp turns ON or Blinking while driving the
vehicle, then it indicates DPF regeneration has not occurred
successfully. At this moment, we suggest DPF regeneration must
be done through a specific methodology. The same is as mentioned
below:
Take vehicle to highway and drive for 20–30 mins @ speeds above 60
kms/hr until the lamp to turns off

DPF park regeneration is only possible when the REGEN telltale
is ON in the instrument cluster
• Park the vehicle safely in a well ventilated levelled open space
and free of any flammable material.
• Shift the gear lever to Neutral with the engine running and apply
the parking brake.
• REGEN screen will appear in the drive info menu of instrument
cluster when the REGEN telltale is ON
