Sorry I wrote that post rather quickly and didn't include any details... What I ment to ask is where is the temperature sensor located on the 03 that is used for the outside temperature shown on the display.
No problem. Just kneel down and look through the "mouth" in the front bumper. Move to the left end of the mouth (left, that is, from the point of view of someone sitting on the driver's seat). You'll easily be able to see the sensor, a small black cylinder held by a bracket attached to the radiator assembly.
