WARNING LIGHTS

Unsure absolutly, but sounds like might be the indicator for if your tailights / light is out. I would have a friend check your lights for you when you step on brakes and turn on the turn signals, regular lights, ect.

If you still have the owners manual check inside that, should have a section on lights that come on that will tell you what it is. ( A parts store may have a book or have someone that can tell you what it is )

If these things dont work and still cant figure it out, take it by a garage you trust and have them check it out.
