Info page symbol

What is the symbol to the right of temperature represent? Cant seem to find it in the books. This symbol randomly appears and disappears on its own. How do I control this? Two pics showing above and below freezing temps.

 

Download the Toyota Owners app from Google play. It has all of the indicators.

 

Ok thanks for the info, I will check it out.

 

Mine stays on from about now until end of February.

 

I've owned the vehicle 3 weeks now and have drove with air temps in mid 70's f and the icon has made itself known then as well.

 

Found the overlooked information in the book. Still doesn't explain why the icon shows up when temperatures are way above 37F. Still doing a shake down of the vehicle so Toyota can service all problems I find in one trip. Carry on......

 

@T-Rex266 I seem to recall 70f but hope to verify this in a screen shot for service. Here in Wi. we are going to have some temps in the low 60's the next few days.

 

It's -1c or 31f right now here. When I start the truck, it flashes and then stays on

I believe ours come on around 0c and stays on.

 

@T-Rex266 Road trip today with temps no lower than 38f and no icon. Like I said earlier, next week will have higher temps in the region and we shall see what happens.
