I'm sorry I don't have a manual for my car, but what does it mean when a light comes on on my dash??? It is an orange aireal pic of a car with three lines in the back, 3 on each side of the car.

 

It means one or more of your brake or rear lamps are burned out.

If it lights up when you press the brakes for the first time ---> burned out brake bulb.

If it lights up when you first turn on you lights ---> burned rear parking light.
