what that means the light in the panel comes up?

Hello the first thing to do is have the on-board computer scaned and find the fault code for the system that is having a possible problem.You should not wait too long or it may becomme a major repair.

Because something is wrong. You need to have the code pulled. If the light is blinking stop driving the car immediatley before you damage the engine. Go to Autozone and get the code pulled then post it up so I can tell you what sensor had detected the problem.
