How (and what) does it know? I have a combination compass/thermometer in the overhead console of the 2000 Expedition that I recently bought. Now that the temperature is dipping below freezing (around here, anyway), sometimes it alternates between the temperature and the word "ICE".
I've been all through the owner's manual but I can't find any info. Specifically I'd like to know:
1) How does it know? Does this just come on automatically at certain temperatures, or do other factors come into it (like falling temp, or rising temp, or something).
2) Does it know anything else? When it's really hot out will it say "HOT"? - or "go to the beach"?
This is just the basic compass/thermometer combo - no trip computer. Any thoughts or info? Red
[updated:LAST EDITED ON 11-Nov-02 AT 03:37 PM (EST)]When the temperature drops below 38 degrees F, the temp reading flashes "ICE" to warn you that ice could be forming on bridges. It only flashes ICE for about a minute after you start the vehicle or when the temperature drops to 38 or below. It does this on my Explorer too.
The temperature the sensor(usually located about 16" above the ground)
reads is Ambient temperature.
Check around the vehicle for a small hole or thermo-coupler looking device.
The temp can change going from icy/snowy road to clear pavement being warmed by the sun.
Thanks for all the feedback, guys. I guess it has no real intelligence, and "ICE" is all it knows how to say. I wish it would flash "HOT", but for that I'd have to move to a heck of a lot warmer climate!
My 2k F-150 also flashes "ICE" below ~38 degrees only for about a minute or two. I believe the temp sensor is behind/in front of the radiator? When I wash the truck, evaporative process lowers temp up to 20 degrees for a short time.
