Emergency question - after driving in city traffic for a few weeks, today my car was put on the highway. After 30 miles at speed varying 80 to 110 mph, the engine warning light came on. (It was the orange light with an engine shape with liquid wave at the bottom.) My temp. was 80C and the oil pressure was 3. I stopped, checked the oil level and looked the engine over. All was fine. However, the light went out when I was back in local traffic. Once back on the highway though, it came on again.

Is this an indicator light for something else I'm overlooking? There is no lose in performance, stalls, etc... Just the light.

Thanks.

I just looked at the CD ROM and there are only two lights that have a line under them. One is the shape of an oil can and the other the shape of a radiator. Which ever one it is, that fluid is marginaly low. If it is oil, add about a quart and a half. If it is the coolant, add to the top of the tank.

I'm sorry. It is a radiator shape. And your right, when I checked it, it was indeed low. I owe you guys so DAMN much! Thanx, I can wipe the sweat from my head. I thought it was the engine. Thank you.

Bear in mind, now that you've topped off the coolant level to keep an eye on it. If it is regularly needing to be topped off you may have a leak somewhere.
