Engine went much slower!

Hello dear friends at MotorTalk! When I started the engine at -13° degrees tomorrow at 6:50 am, the engine was still on P and the engine was running very slowly. As if he had just hibernated. While driving I noticed that he didn’t give immediately what I gave by pedal. Everything was really slow, he didn’t want. OK, the engine of my V40 couldn’t do as it wanted because it was very cold. I don’t know it so, but after many minutes it ran as always. You just have to give him a lot of time! Battery charging every month is important!
