The thermometer sensor (15A022) is attached to the radiator frame behind the grille. The temperature can be displayed in Celsius or Fahrenheit by pressing the MODE switch. If the outside temperature falls below 3.3°C (38°F), the display will alternate from "ICE" to the outside temperature at a two second rate for one minute.
The outside air temperature reading can be affected by engine heat when the vehicle is idling or has been off for less than two hours. The compass and thermometer (19A548) will limit the increase of the displayed temperature to one degree per minute at very low speeds or immediately after the ignition is turned on. After two minutes at a sustained speed of at least 53 km/h (33 mph), effects of engine heat are minimal and the compass will display the current outside temperature reading. Temperature decreases are always updated immediately.
If the outside air temperature sensor is short or open circuited, then the display will show 60°C (140°F) or -40°C (-40°F) respectively in place of temperature.
