I had this happen also would come one while driving, but I would just shut the car off and restart it and it would clear. I found out later that it was caused by the battery, cause I replaced it a few days later and have not had it come back yet.

that's two votes for the battery so far. Maybe we should start a poll. Maybe involve a little gambling and see what the outcome is.

Well, i stand corrected. I recently went through a lot of problems with power in my SVT including a low charge on the battery, but if this is a battery voltage problem or a connection problem, i havent seen it before.

you are correct though QQQQ, your battery light will turn on when the alt. is not charging the battery, but i believe it could indicate other problems as well.

in my opinion, it sucks that the owner's manual doesnt specify what the problem is. it only says "have your vehicle serviced". by the name of it, since you do not have an automatic trans, it would seem that it would be the cooling system.

(from http://www.myfordfocus.com/underthehood.htm)
Engine Cooling System
If your Focus has the 2.0L Zetec engine, your have what is referred to as "fail-safe cooling". This is a handy system, should for some reason your engine's coolant supply become depleted, the fail-safe cooling allows the vehicle to be driven temporarily before any incremental component damage occurs. The fail-safe traveling distance depends on ambient temperatures, vehicle load, and terrain.

If your engine begins to overheat, the coolant temperature gauge will move into the red area, and the multi-function automatic transaxle/cooling system light on your instrument panel will be illuminated. When the engine reaches a preset over-temperature condition, the fail-safe cooling system will activate. The engine will switch to alternating cylinder operation, each disabled cylinder acts as an air pump, thereby cooling the engine.

When this happens, your vehicle will still operate, however... the engine power will be limited, since you are not running on all four cylinders, the air conditioning system will be disabled, and your check engine light on the instrument panel will illuminate. Continued operation will increase the engine temperature and eventually the engine will shut off, and you will loose your power steering and bracking. If at all possible, you should pull off the road and let the engine cool. If you car does shut off, and once your engine cools down, you should be able to start the car again. You should however get your car to a service facility as soon as possible.

THAT ^ scenario def did not happen.The car was just started and was NO WAY overheating AND the light went out after 3 minutes.I drove away after that and had plenty of power.I still think it had something to do with battery voltage being too low.

??? the air bag lite is much different looking and you can actually figure that one out without a manual...this is the one below the air bag lite.

Well with all the information at hand so far, I'm willing to guess that the problem is with the fail-safe itself. I don't know what components make up the fail-safe (just a temp sensor and the ECU? maybe more?), but this is the best place to start. Perhaps the bad battery causes a voltage issue with the sensor?

Normally I'd think that this kind of system would run off the alternator when the car is running, but perhaps it is wired to the battery because of its fail-safe operation?

Just some educated guesses... hopefully we can make more of the situation from here.

This light is not applicable to the SVTF.
