I have seen this symbol pop up multiple times and it seems to change when I switch profiles. What is the engine symbol with thermometer indicating? I cannot find this in the owners manual. This may be a thread somewhere not really sure.

 

Symbol is Engine temperature.
OK means no problem.
Guage shows running temperature.

 

I wondered the same thing, when I got mine a few days ago.

Along with "OK", first thing in the morning, it says "COLD" and the indicator is over to the left (the blue end).

Yes, it is amazing the number of things which are NOT in the manual. Do they just assume we know?

 

Thats also a 2015/2016 graphic.
The new dealer coding changes that graphic to be more clear.
