Yelllow light in the dashboard

[gonfire]

Hi guys, I have a Mazda 3 GT 2006 and drove with it last night. Right after I went to the gaz station and filled up the car with brand new juice, I noticed a yellow light that looks like an engine with an exclamation point right beside it.

So I read the user manual to see what it said about this light:
1.Anti-pollution air system is not functionning normally
2. Fuel tank is very low
3. Electric problem with engine system

Since the fuel tank was indeed very low right before I went to the gaz station, I ignored the light. When I got back in my car this morning, it was still on.

The car has 68 000 miles and is working has useual
Whats could be wrong?

Hi gonfire,
Could be the gas cap not on all the way. I had the engine light come on recently on my '08 and it turned out to be that. Dealer replaced cap under warranty and said they were having problems with some of them. The last few months I noticed cap was hard to put on and off, and sure enough it was defective. good luck,
