How do I regenerate my vehicle's DPF?

Can you please advise how to regenerate the DPF on a Mercedes-Benz E-Class?

If you regularly drive distances of 50 miles or more the DPF will passively regenerate and occasionally actively regenerate. If you don't regularly drive distances it will have to actively regenerate by introducing diesel fuel to the DPF, starting a fire in there and burning off the soot.
