hello all, my name is rusty and i am new to this site. i have a 2010 versa. it's a great family car. i have twin girls so it is plenty big enough and get's great mpg's. today when my wife was on her way home the brake warning light. the one that is the ! in a circle surrounded by the ( ). i checked the manual to see what to do and it said to check the fluid. i did and filled it up and the light is still on. how long will it take for the light to go off? thanks and have a great day.
