When Driving

Diesel Particulate Filter

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 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 "Soot Accumulation in DPF too
high" 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 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 "DPF malfunction" is indicated
Contact an expert repairer, we recommend
an Authorised Mazda Repairer.
NOTE
The engine sound and exhaust gas smell
may change when PM is being removed
while driving.
