I have a 2006 Gs300 automatic 6speed trans and 250hp 6cyl. I live in New Jersey had lots of snow and ice. I started the car the other day and the brake warning light yellow, check engine light adn slippery display are on and won't go off. It says check vsc on the main display. My mechanic says it should reset but it hasn't. The car is driveable. Do I need to take it to Lexus dealer?
