Diesel Particulate Filter

(SKYACTIV-D 2.2)

The diesel particulate filter collects and
removes most of the particulate matter
(PM) in the exhaust gas of a diesel engine.
PM collected by the diesel particulate
filter is cleared during normal driving,
however, PM may not be removed and the
diesel particulate filter indicator light may
illuminate under the following conditions:



If the vehicle is driven at 15 km/h (9
mph) or less continuously.



If the vehicle is repeatedly driven for a
short period of time (10 minute or less)
or driven while the engine is cold.



If the vehicle is idled for a long time.

When “DPF Clogged” is indicated

The particulate matter (PM) cannot be
removed automatically and the amount of
collected PM reaches a specified amount.
After the engine has sufficiently warmed
up (engine coolant temperature of 80 °C
(176 °F) or more), depress the accelerator
pedal and drive the vehicle at a speed of
20 km/h (12 mph) or more for about 15 to
20 minutes to eliminate the PM.

When “DPF malfunction” is indicated

Contact an Authorized Mazda Dealer.

CAUTION

If the vehicle continues to be driven with
“DPF Clogged” indicated in the display, the
particulate matter (PM) increases and the
indication may change to “DPF
malfunction”. If the indication changes to
“DPF malfunction”, have the vehicle
inspected immediately at an Authorized
Mazda Dealer. If the vehicle is not
inspected and continues to be driven, the
engine may malfunction.

NOTE



When “DPF malfunction” is indicated
in the display, the engine output is
restricted to protect the diesel
particulate filter.



The engine sound and exhaust gas smell
may change when PM is being removed
while driving.
