Multi-function displayTIPThe multi-function display performs
the following self-test for three sec-
onds in order to check the electrical
circuit.
The speedometer digits display
from 0 to 80, and then from 80 to
0 in kilometers. If the speedometer
is set to miles, the digits will dis-
play from 0 to 50, and then from
50 to 0.All LCD segments and warning

WARNING
EWA12313
Be sure to stop the vehicle before
making any setting changes to the
multi-function display. Changing
settings while riding can distract the
operator and increase the risk of an
accident.The multi-function display is equipped
with the following:
a digital clock
a digital speedometer (which
shows riding speed)
an odometer (which shows the to-
tal distance traveled)
a tripmeter (which shows the dis-
tance traveled since it was last set
to zero)
a fuel reserve tripmeter (which
shows the distance traveled on
the fuel reserve)
an oil change indicator (which
shows when the engine oil should
be changed)
a fuel gauge
a self-diagnosis device
