I believe that is the Tire Pressure Monitoring System telling you that a tire is low. If this is the case the odometer screen should be displaying "Tire Reset" instead of your mileage. I will tell you that I own a 2004 Ford Freestar SE and have found that warning light to be incredibly unreliable. It worked properly once and ever since has given me trouble. When I have a flat tire it doesn't tell me and when I don't have a flat it tells me that I have one.

The Lincoln navigator yellow exclamation point on the instrument panel, is an indication that the engine needs to be checked. The yellow color means caution.
Low tires.
The yellow exclamation point light on a Honda Accord is designed for the Vehicle Stability Assist system. It comes on when the vehicle is trying to maintain stability or when a tire is low.

The red exclamation point in a circle is the parking brake indicator.
In the Chevy Aveo, the exclamation point warning light in a circle, means that the air pressure is low in one or more of the tires. This is per the owners manual.
Tire pressure.
Caution or warning
There should be a red circle with a yellow exclamation point in it. Clicking on that will either open the shop or a dialog box with a shop button.
It definately means you have bulb out...this just happened to me and my turn signal/brake light is out.
That is a "Check transmission light"
