Mazda2 DJ 2014–2021 Owners Manual / When Driving / Diesel Particulate Filter (SKYACTIV-D 1.5)

The diesel particulate fi lter collects and removes most of the particulate matter (PM) in the exhaust gas of a diesel engine.

PM collected by the diesel particulate fi lter is cleared during normal driving, however, PM may not be removed and the diesel particulate fi lter indicator light may illuminate under the following conditions:


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

Diesel Particulate Filter Indicator Light

When illuminated

The particulate matter (PM) cannot be removed automatically and the amount of collected PM reaches a specifi ed amount.

After the engine has suffi ciently warmed up (engine coolant temperature of 80 °C or more), depress the accelerator pedal and drive the vehicle at a speed of 20 km/h or more for about 15 to 20 minutes to eliminate the PM.

When fl ashing

Contact an expert repairer, we recommend an Authorised Mazda Repairer.


If the vehicle is continually driven as usual with the diesel particulate fi lter indicator light illuminated, PM increases and the indicator light may start fl ashing.

If the diesel particulate fi lter indicator light starts fl ashing, have the vehicle inspected immediately at an expert repairer, we recommend an Authorised Mazda Repairer. If the vehicle is not inspected and continues to be driven, the engine may malfunction.


When the diesel particulate fi lter indicator light fl ashes, the engine output is restricted to protect the diesel particulate fi lter.
