XC60 Automatic in Frost Weather

Hello, the automatic of my XC60 D3 FWD (40,000 km) always requires 2-3 km of driving distance at outside temperatures below 0 degrees until it switches normally after a cold start. Is this normal? Until then I would have to cheer up the engine speedwise in order to get from the place. At some point it switches as usual and everything is good. Is this a bug or a feature?
