How Do You Tell?

[Jaminglish]

How do you tell the difference between the heated screen and none heated? Also on the mirror, there appears to be something like a sensor, what is this for? (IS 200 SE, 2002) Input please....

If you look at the bottom of the screen where the wipers sit,you'll see a couple of wires in the glass,it only really heats the bottom of the screen to save the wipers freezing, not the whole screen like Fords,the sensor on the interior mirror is for the anti-dazzle function,HTH.

They're all heated (unless the windscreen has been replaced with one without the heater) but as above only the bottom where the wipers are. What do you mean by the "sensor" on the mirror, IS200 doesn't have autodimming mirrors (except the LE) unless it's been fitted afterwards?
