the distance traveled from when the
fuel level dropped to the reserve level.
Selecting a mode
Push the “SELECT” button to change
between the odometer mode “ODO”
and the trip odometer modes “TRIP 1”
and “TRIP 2” in the following order:
“ODO”

If the fuel level indicator light comes on
the odometer display will automatically
change to the fuel reserve trip meter
mode “TRIP F” and start counting the
distance traveled from that point. Push
the “SELECT” button to change be-
tween the fuel odometer, trip odometer
and odometer modes in the following
order:
“TRIP F”
