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 earlier in this
section. Record your zone number.
2. Press and hold both the MODE and the US/MET
buttons in the COMP/TEMP 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 US/MET 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/TEMP mode.TRIP: Once in the TRIP mode, pressing the
MODE button will step you through the following
TRIP functions:
AVG ECON (Average Economy): The average fuel
economy since the last reset is displayed.
INST ECON (Instantaneous Economy):
Instantaneous fuel economy for the last second of
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 for the last
few hours of driving.
FUEL USED: The fuel used since the last reset is
displayed.
AVG SPEED (Average Speed): The average speed
since the last reset is displayed.
To reset the trip computer, press the MODE and
US/MET buttons simultaneously for at least two
seconds. All functions will be displayed briefly 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.
