Hopefully you don't. However if you stop the engine mid regeneration you will find the radiator fans blow flat out and a distinctly hot air feeling and often a smell as well.
Just drive and don't worry about it. Volvo's system should be very reliable because the DPF is attached directly to the turbo, so there is very little heat loss between the engine and filter. In some other engines, like the transverse engine versions of JLR's, the DPF is remote mounted with a long piece of pipe between it and the engine, allowing substantial cooling, which causes a lot of problems in starting the regeneration burning process.
