This is going to sound crazy but this is a true story, corroborated twice on my 2007 GS450h... The problem is that my brake level went out of range. I swear that this is what was determined to be the problem and it may be your problem too. I had the exact same problem as you. In cold temps the brakes and all the lights were an issue. Once the car warmed up everything would become operational and all the lights would reset. You see, my brake pads were worn and this caused my brake fluid to drop below a certain range in the master cylinder. I took it to the dealer and they reset the computer and added just a little fluid. Light problem solved....for now..... So I bought new pads and did the pad change. Great right? Nope, now the fluid had risen ltoo high since and I did not suck out enough fluid and/or it was just too sensitive to the fluctuation in the master cylinder fluid. I called the dealer again, took it in and they reset the computer....no proble going om 9 months. It has everything to do with the brake fluid level in the master cylinder and resetting the computer. No kidding. I feel really confident since I had all the lights shown above and my brake power assist would cut out till the car got sufficiently warmed...or the brakes got sufficiently warm. Absolutely nuts but what a gem to know that this is nothing that requires anything in the way of surgery to resolve.
