If it is not down to your left right beside your pedals, I would take a look in the fuse box under the hood next to your battery. The fuse might be shared with other components, so have good light with you and check them all.

That symbol is the low tire pressure light. You have a tire that is right at the minimum threshold. The light goes off as the tire temperature rises, and, as the temp rises, the internal air pressure also rises slightly. Just check the tires with a good pressure gauge, inflate them to the specs printed on the tag inside your driver's side door, and you will be just fine.

That's for your tire pressure on your car (TPMS). Most times when the tire pressure goes below 25psi, the light on your dash goes on.
You may have a nail in your tire. Or, they are just low.
Air them up to 35psi and the light should go out. Sometimes, there is a pressure senor in the spare tire. To be safe, check the air in the spare tire also.
