it is your check engine light. If it is on you are having problems with normal operation of the engine. Most of the time it is something very simple and emission related. Normally it is an exhaust gas regulation valve(egr) or an oxygen(o2) sensor. Go to auto zone and ask them to scan it for you to get the code that your power train control module(pcm) will have stored. They should do it for you for free. If you take it to a dealer they normally charge about 35 to 50 dollars to use their scan tool.
"Check Engine".
it looks like a transmission or the check engine light will come on
I was looking at the 2001 Ford Windstar Owner Guide and the warning light : above the tachometer is the check fuel cap light below the engine temperature gauge in the middle is the bulb warning light , one of the exterior bulbs has burned out
My interpretation of the graphic is it represents a tire that is bulging at the bottom - like what a low tire looks like when viewed from behind the vehicle.
One of your exterior bulbs is burned out ( the warning light is in the right / lower area of your instrument panel )
Ignition coils for diesel engine glow plugs, wait for the symbol to go out on the dash, 10 secs aprox and then start the engine
Oil Can? Oil pressure low?
I believe it is the "service engine soon" indicator. You will have to have someone with a code scanner read the code it is giving though. Some auto parts places will do it for free for you. It looks like a square but it has somethng on each of the sides of the square. Then this I believe is what that means. I hope this helps.
One of the exterior bulbs has burned out if the warning light that looks like a light bulb ( located below your engine temperature gauge ) has lit up
You can drive your car with the yellow 'service engine' light on the dashboard, but it is not recommended. This light warns you of the need to have the engine serviced.
Traction Control.
It looks like the word BRAKE. It is pronounced as BRAKE also.
