Need for Manual Regeneration:-
During normal driving, the filter is automatically regenerated every several hundred kilometers. However if vehicle is continuously being operated in below mentioned conditions, Automatic regeneration cannot be performed.

For the above conditions,
PM continues to accumulate and manual regeneration is required to ensure normal operation of DPF.

I.When regenerating the filter during driving the vehicle

To regenerate the filter, the following driving methods are recommended

1. By driving continuously (for example, at around 60 km/h. for 20 to 30 minutes. By avoiding short trips, or by driving continuously (leaving the engine running for long periods of time). Check the engine is warmed up before driving the vehicle to regenerate the filter. If the engine is cold, warm up the engine by driving the vehicle downshifting to increase the engine speed.
2. The warning message will disappear on the multi-information display when regeneration is complete. However, depending on the driving condition such as heavy traffic, the amount of accumulated deposit increases and the warning message may not disappear on the multi-information display

If the warning message does not disappear on the multi-information display after driving, press the DPF system switch to manually regenerate the filter.

ii. Regenerating the filter by pressing the DPF system switch

Stop the vehicle in a safe place.

Shift the shift lever to P (automatic transmission) or N (manual transmission), and firmly set the parking brake.

Do not stop the engine

Also, make sure that there are no flammable materials near the exhaust pipe. Check the engine is warmed up. If the engine is cold, warm up the engine by depressing the accelerator pedal.*1

Press the DPF system switch.

The DPF system warning message shown in the illustration appears on the display, and the idling.engine speed will increase

Regeneration will take around 30 - 40 minutes to complete.* 2

When the DPF system warning message goes out, the idling engine speed will have finished returning to normal.

*¹: Depending on the situation, it may be necessary to depress the accelerator pedal until the engine speed is increased to 3000 rpm. If the engine coolant temperature or exhaust gas temperature is low, it may take a long time to regenerate, or regeneration may be impossible
*²: Time required for regeneration differs in accordance with the outside temperature. Also, if the engine speed is still approximately 2000 rpm and 10 minutes after pressing the DPF system switch, the exhaust gas temperature may be low. In this case, depress the accelerator pedal to run the engine at approximately 3000 rpm for a while. While depressing the accelerator pedal, regeneration might stop, in that case restart the regeneration.
