My 2019 Prado did not come with a manual button but there are instructions about how to run if a DPF burn needs to occur if it does not go automatically. So far no hassles for my vehicle, though much of the driving is highway driving over 1-2 hours or longer trips. I have TorquePro app for engine and transmission monitoring but often too busy driving to see what the typical distance interval is for normal driving. Probably about intervals of 300km under normal driving but closer together under hard conditions.
Although I do see when a burn occurs by seeing the DPF% change, always starts a burn at 100% and burns down with 5th injector operating. I notice the fuel consumption increases by a couple of Litres/100km during a burn. The last two Exhaust Gas Temperature Sensors have increased temperatures during a burn, over 500degC or more
The 5th injector seems to cut off around 8 to 6 DPF% and regularly the DPF% will decrease to 0 or 2% presumably due to some residual heat if the vehicle continues. If the vehicle is shut-down during a burn, a burn will restart, whether in an urban trip or a longer trip, so that DPF% goes to low value. I have read somewhere that often some DPF%s often only go to 8% without problems.
