I just got this car couple of weeks ago. Today One light on the indicators turned on. I have an old driver's guide but I'm not able to find the correspondent icon. The light is on the rigth side, just between oil and brakes. The icon is like the "Parthenon" two horizontal lines and 4 perpendicular lines, and a short triangle on top. No idea what can be wrong. I really apreciate any help you can give me.

 

It's the water level alarm. It comes on when water level in the overflow tank drops too much. Sometimes the sensor sticks if sealers were put in the cooling system. Then the idiot light won't go out after adding water. To fix that first remove any sealers from the cooling system, flush it well and refill with correct coolant. Then remove the overflow tank and clean it. Shake it and listen for the rattle of the sensor float. Flush it until you hear the rattle. Else replace the sensor.
