I have found out that the last indicator on my dashboard console (A circle with an exclamation mark in thecenter (!) ) lights up occassionally when i am driving . It started after a spate of hard driving one weekend i was out with my fiancee and ever since then it comes on and goes off.

Be that as it may , I would like to know what exactly this light indicates and I would like to know what this is before it turns into a major problem.

Will appreciate ur advice .
