Diesel Particulate Filter (SKYACTIV-D 1.5, 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.

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

When illuminated

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 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.
