Diesel Particulate Filter

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 warning indication/warning 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.
