I recently bought my 2006 IS250, and when I went to start it today I noticed that after adjusting the climate the nav screen went black. After trying to press different buttons not on the screen (voice command, radio controls, climate off, auto, etc.) none of them would work either. A few seconds later the car turned off and said "CHECK VSC". After trying to restart the car, the brake pedal doesn't really press. Thinking back I don't really remember if the car started in the first place, I think it just stayed in accessory mode. After exiting the car it did lock though. This is my first car and I've only had it for about a month. Any suggestions would be appreciated.
