We bought a 2009 Toyota Hybrid last year. It has been running well until this morning. The car wouldn't start and a warning came up "check brake system." Any ideas what to troubleshoot? Thankfully I didn't have the issues when driving long-distance on snow and ice yesterday. I've loved this car for its good gas mileage and excellent handling on winter roads. I am not near a Toyota dealer or specialized mechanic. Any advice or direction would be greatly appreciated. Please and Thank You.
