Took a picture of my Scan Gauge last week when it was -15. It was parked outside for couple hours and the fluids were freezing.... I got a kick out of it. The response time of the screen was unusually slow due to the cold. The truck started, but a lot of noises coming out from under the hood for the first couple seconds. The steering very hard and the suspension stiff. I guess all the liquids were at very low viscosity due to the cold.
