Lowest Temperature shown in display.
Hi all,
It's starting to get cold again and I was thinking about how low the temp gage can reach. Lowest I've seen on mine is -30 degrees celcius (~-22 F), even though the temperature was -40 outside. I wonder if that is as low as it will reach or if the sensor is getting some heat from the car. This happened many times, under different conditions -- highway, city driving and parked. Anyone ever see it go lower?

Good point. I haven't specifically checked. Seems like I read the section and don't remember seeing anything about how low it reaches. Will check.

In most applications, the display will either fix on a low number or blank out with -- when the temp is out of range. There could also be a diff between Canadian and US models.

"The temperature sensor is in the front bumper. Therefore, the temperature reading can be affected by heat reflection from the road surface, engine heat, and the exhaust from surrounding traffic. This can cause an incorrect temperature reading when your speed is under 19mph (30 km/h)."
My guess is that because the outside temperature is so low, the heat produced by the engine would be relatively more significant and therefore offset the temperature reading by this much.
"If the outside temperature is incorrectly displayed, you can adjust it up to +/- 5 degrees Fahrenheit warmer or cooler."

Tweaking is not the problem that I have. It seems to be fairly accurate until it gets low, and doesn't read below -30C.
RMATIC09, was that -35 you saw? Mine doesn't go that low.
ianS, I bet you are wrong. Absolute zero is -273.15C or 0 Kelvin. That's as low as it can go!

And yes you're right, below -273.15 degrees Celcius would be an out of this world temperature.

I think RMATIC09 is in fahrenheit, but I don't know whether that's colder or warmer.
The outside temp guage seems to only show integers, so you'll never see -273.15. Actually it seems to only have 2 digits, so I don't think you'll see -273 either.

Hey, I almost forgot, when I went to embark on my ascent, this guy comes out and makes sure that your car meets the rules for safe travel on the ascent/descent.
One of the rules is...............
NO 5ATs ALLOWED!
Actually, any car with an SS tranny...............

Also, I'm sure the guy who will get the coldest reading is the one who lives in the North-West Territories... I forget what his alias is. Let's have a contest for the coldest temp photo... In Ottawa we should be in the running.
