I've noticed that the Auto climate control setting tends to direct more air toward the windshield than I'm used to in cold weather. That means there's less heat coming out below. I've found it helps to manually direct the air exclusively toward the feet/floorboard vents until my feet warm up. Hope that helps.
Thanks Jezza. I just returned from the dealer for my 20,000 mile services, and asked if I was not operating the vents properly. He said most people don't realize that you have to turn the vents on through the climate control system on the screen by clicking on the fan/vent icon and choosing if you want top, middle and/or bottom on the driver who shows up on the screen. Just in case anyone else was wondering.
