I believe that is the tire pressure alert. Check your tires. You might look in the Owner's Manual for all the alerts available.
Definitely air pressure alert. They are pretty accurate these days and really mean at least one tire is low on pressure. I recently got the same on my 2010 recently a couple of times. I purchased a good tire gauge to carry around as all the gas stations have air but no gauge attached (though some of them have a gauge to borrow in the store).
