This warning light flashes or stays on if
an electrical circuit monitoring the en-
gine is not working correctly. If this oc-
curs, have a Yamaha dealer check the
self-diagnosis system.
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on

Multi-function meter unit
WARNING
EWA12423
Be sure to stop the vehicle before
making any setting changes to the
multi-function meter unit. Changing
settings while riding can distract the
operator and increase the risk of an
accident.
The multi-function meter unit is
equipped with the following:a speedometer
a tachometer
a clock
a fuel meter
a coolant temperature meter
an odometer and tripmeter display
a multi-function display
a self-diagnosis device
TIP
B e s u r e t o t u r n t h e k e y t o “ O N ” b e -
fore using the “SELECT”, “RE-
SET” and “INFO” buttons.
When the key is turned to “ON”, all
display segments of the multi-
function meter unit will momen-
tarily appear in order to test the
electrical circuit. The speedome-
ter, tachometer, fuel meter and
coolant temperature meter will
then perform a display check and
a welcome message will scroll
across the multi-function display.
For the U.K. only: To switch the
speedometer and multi-function
displays between kilometers and
miles, press the “SELECT” and
“RESET” button together, turn the
key to “ON” and then release the
buttons. Press the “SELECT” but-
ton to switch between kilometers
and miles and then press the “SE-

When approximately 3.0 L (0.79 US
gal, 0.66 Imp.gal) of fuel remains in the
fuel tank, the display will automatically
change to the fuel reserve tripmeter
mode “F TRIP” and start counting the
distance traveled from that point. In
that case, pushing the “SELECT” but-
ton switches the display between the
various tripmeter and odometer modes
in the following order:
ODO → TRIP 1 → TRIP 2 → F TRIP (fu-
el reserve tripmeter) → ODO
To reset a tripmeter, select it by push-
ing the “SELECT” button until “TRIP 1,
TRIP 2, F TRIP” is displayed. While
“TRIP 1, TRIP 2, F TRIP” is displayed,
push the “RESET” button for two sec-
onds. The fuel reserve tripmeter will re-
set automatically and disappear after
you have refueled and turned the key
to “OFF”.Multi-function display
The multi-function display is equipped
with the following:
a fuel consumption display (aver-
age and instantaneous consump-
tion functions)
an average speed display (which
shows the average speed since
last set to zero)
a time tripmeter (which shows the
elapsed riding time since last set
to zero)
 an oil change indicator with an oil
service reminder (which shows the
riding distance since last set to ze-
ro)
a low battery voltage warning indi-
cator
a warning message function
a self-diagnosis device
Push the “INFO” button to switch the
display between the average fuel con-
sumption mode “C Ave__._km/L” or “C
Ave __._ L/100 km”, the instantaneous
fuel consumption mode “C
