The compassis self-calibrating, so it does not need to be manually set. However, if C (Calibration) is displayed, the compass will need to be calibrated. You may also place the compassin a noncalibrated mode by pressing and holding the MODE and USMET buttons simultaneously whilein the COMP/TEMP mode. After about 10 seconds, the compass will display C and you can release the buttons. Drive the vehiclein a complete360" circle threetimes at a speedof less than 5 mph (8 km/h), and the compasswill function normally. Once the calibration is complete, the display will return to a compass reading. Variance is the difference between magnetic north and geographic north. In some areas,the difference between the two canbe great enoughto 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 earlier in this section. Note your zone number. 2. Press and hold both the MODE and the US/MET buttons in the COMPREMP mode. 3. After five seconds,the compass will acknowledge the variation mode by displaying the current zone number. When it does, release both buttons. 4. Press USMET until your zone number appears on the display. 5. Press MODE to enter your zone number. Your variance is now set and the display will return to the COMP/TEMPmode. TRIP: Once in the TRIP mode, pressing the MODE button will step you through the following TRIP functions: AVG ECON: The average fuel economy since the last reset is displayed. INST ECON: Instantaneous fuel economy for the last secondof driving is displayed. RANGE: The display indicates the estimated distance that can be travelled with the remaining fuel in the tank, based on the fuel economy forthe last few hours of driving. FUEL USED: The fuel used since the last reset is displayed. AVG SPEED: The average speed since the last reset is displayed. To reset the trip computer, press the MODE and USMET buttons simultaneously for at least two seconds. All functions will be displayed for half a second once the system is reset. Reset can only be performed in the AVG ECON, FUEL USED and AVG SPEED modes. All three modes are reset simultaneously. 2-55
