That's not bad...I've gotten "Ice Possible" on the DIC on mild winter days at 52 degrees. After a call to tech support, dealer gave me a bunch of mumbo jumbo about "that's how it's supposed to work". So, if the manufacturer is leaning towards the conservative here, I'd say that is
quite a lean, rivals the Leaning Tower of Pisa. But then again, maybe it's just that the H2 is the 8th Wonder of the World
Seriously though, if you notice, the temperature indicator on the rear view mirror is always off, mine by as much as 7 to 8 degrees. So maybe that's the reason for your getting "ice" at 37 degrees?
