When out side temperature get near freezing, temperature display will come up with temperature (as well as "ICY") even though you dont have display set for temperature (lets say MPH). After a minute or so, your older display will come back.
Have you guys experienced that?

 

same goes for tire pressure and gas gauge I think. havent tested it out. but if anything has something urgent to tell you, it wont go away till you fix it.

 

This is normal behavior... think of it as an 'alert'. Any of the modes which require attention will pop-up to alert you of the item.

Its all in the manual...

 

I guess I'll never see that ICY display on my Z down here
