Turn the display on or off by pressing the ON/OFF button. Display the temperature in either degrees Fahrenheit (English) or Celsius (metric) by pressing the US/MET button. Before you turn on the ignition and move the vehicle, the temperature indicated will be the last outside temperature recorded with the ignition on. If the outside temperature is 37_F (3_C) or lower when you turn on the ignition, "ICE" will appear on the display. This is a warning to the driver that road conditions may be icy, and that appropriate precautions should be taken. The compass is self-calibrating, so it does not need to be manually set. However, when your vehicle is new, the compass may function erratically. If it does, "CAL" (Calibration) will appear on the display. To correct the problem, drive in a complete 360 degree circle three times, and the compass will function normally. Variance is the difference between magnetic north and geographic north. In some areas, the difference between the two can be great enough to cause false compass readings. If this happens, follow these instructions to set the variance for your particular location: 1. Find your location on the zone map. Record your zone number. 2. Press and hold both the ON/OFF and the US/MET buttons. The display will go off. 2-65
