Temperature flashing!

Noticed it on drive home from gf house. The degrees bit was flashing. It was about 2 degrees so I'm guessing it's a frost warning? Used to have a small snowflake appear on my Corsa, guessing its the same principle?
Cheers
 
Yes indeed, think it happens 4 degrees and below. Best I've had on mine was -19, but I got this pictured one morning :smile:
