This warning light comes on when the fuel level
drops below approximately 4.0 L (1.06 US gal,
0.88 Imp.gal). When this occurs, refuel as soon as
possible.
The electrical circuit of the warning light can be
checked by setting the engine stop switch to “ ”

EBU30495Multi-function display (YFM70KPXG /
YFM70KPHG / YFM70KPSG)
The multi-function display is equipped with the
following:
a speedometer
an odometer
two tripmeters (which show the distance trav-
eled since they were last set to zero)
a clock
an hour meter (which shows the total time the
engine has been running)
a fuel meter
a self-diagnosis device
Odometer and tripmeter modes
Pushing the “SELECT” button switches the dis-
play between the odometer mode “ODO” and the
tripmeter modes “TRIP A” and “TRIP B” in the fol-
lowing order:
ODO → TRIP A → TRIP B → ODO
To reset a tripmeter, select it by pushing the “SE-
LECT” button, and then push the “RESET” button
for at least three seconds. The tripmeters can be
used to estimate the distance that can be traveled
with a full tank of fuel. This information will enable
you to plan future fuel stops.
