The blue coolant light is to show you that the engine is cold. This is to let you know to drive slow and gentle until the engine warms up. The old saying is that 90% of the engine wear occurs during the first 10% of driving.
how can i tell when the No Light is on ??? (mj)NO LIGHT = Engine is at NORMAL temp. Drive it like you stole it.
Did you actually check the physical level of the coolant in the reservoir before posting about low coolant? My guess is no. Seriously.... this just scares me that I drive the same road ways as people like this. The manual is there for a reason, the blue light is just saying the engine is cold, not the level of coolant.
OK, it was a question that could have been easily researched in the manual. So the poster didnt do that. This is a forum to ask questions about Mazda's , not just the questions you feel are appropriate. Your response was unnecessary and condescending, but as long as we are on the subject, I'd rather drive on roads with "people like this" than with people like you.
I really don't care what you think of me or if you feel I was being condescending, which I was. Sometimes the world and the people in it can be harsh. It's the stark reality of life. I don't have a problem with what OP was asking, just the way he did it. Should have asked "what does the blue light at start up mean?" The fact that the OP was assuming he had low coolant and needed to go the dealer is ridiculous. The manual covers all warning lights and what they mean, a properly worded question would get a proper answer, a stupid assumption just makes an a$$ out of U and Me! A little common sense goes a long way and yes, there is such a thing as a stupid question. And if you don't believe there are stupid questions then there sure are stupid people.
Guys calm down. Its a light. I had the same question (i did figure it out in the manual...) its a legitimate question.
