Do you have Sirius XM weather/traffic? If you do its one of a few weather forecasts symbols. I don't know what weather condition this is though. The other symbols are easy to distinguish.

 

Maybe its foggy conditions??

 

Proximity warning is ON. Telling you the body of your car is set to warn you when you are close to another object, or another object is close to you. Will typically light up and sounding morning when it is activated.

 

The symbols at the top left just above compass are weather icons. The only way for you to have weather icons is to have a subscription to Sirius XM weather/traffic service and be on the compass page or display.
If you don't have said service (weather), these weather icons won't appear. There are a few icons that appear according to weather conditions. I can take pictures daily of different icons and post later.
