Durango 2WD V8-4.7L VIN N (2001)
Automatic Compass Calibration
This compass is self calibrating which eliminates the need to manually set the compass. When the vehicle is new, the compass may appear erratic
and the CAL symbol will be displayed. After completing three 360' turns in an area free from large metal or metallic objects, the CAL symbol
will turn OFF and the compass will function normally.
Compass Variance
Compass Variance is the difference between Magnetic North and Geographic North. In some areas of the country, the difference between
Magnetic and Geographic North is great enough to cause the compass to give false readings. If this occurs, the compass variance must be set.
To Set The Variance
Turn the ignition ON and set display to Comp./Temp. while pressing the US/M button, press the STEP button for approximately five seconds. The
"VAR" symbol will light and the last variance zone number will be displayed. Press the US/Metric Button to select the proper variance zone as
shown on the map. Press the Step button to set the new variance zone and resume normal operation.
THERMOMETER
The thermometer displays the outside ambient temperature in whole degrees. The temperature display can be changed from Fahrenheit to Celsius
using the U.S./Metric push button. The displayed temperature is not an instant reading of conditions, but an average temperature. It may take the
thermometer display several minutes to respond to a major temperature change, such as driving out of a heated garage into winter temperatures.
When the ignition switch is turned to the OFF position, the last displayed temperature reading stays in the thermometer unit memory. When the
ignition switch is turned to the ON position again, the thermometer will display the memory temperature if the engine coolant temperature is above
about 52 °C (125 °F). If the engine coolant temperature is below about 52 °C (125 °F), the thermometer will display the actual temperature sensed
by the ambient temperature sensor. The thermometer temperature display update interval varies with the vehicle speed.
The thermometer function is supported by an ambient temperature sensor. The sensor is mounted outside the passenger compartment near the front
and center of the vehicle, and is hard wired to the HVAC control head which sends temperature on J1850 data bus circuit. The ambient
temperature sensor is available as a separate service item.
NOTE: The compass mini-trip computer will display "OC" for temperatures below -40 °C and "SC" for temperatures above 55 °C.
