When the key is turned to “ON”, the
speedometer needle will sweep once
across the speed range and then
return to zero in order to test the elec-

Tachometer
1. Tachometer
2. Tachometer red zone
The electric tachometer allows the
rider to monitor the engine speed and
keep it within the ideal power range.
When the key is turned to “ON”, the
tachometer needle will sweep once
across the r/min range and then
return to zero r/min in order to test the
electrical circuit.
ECA10031
Do not operate the engine in the
tachometer red zone.
Red zone: 10000 r/min and above

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.

4. Oil change indicator “OIL”
The multi-function display is equip-
ped with the following:
a fuel meter
a coolant temperature meter
an odometer
two tripmeters (which show the
distance traveled since they were
last set to zero)
a fuel reserve tripmeter (which
shows the distance traveled sin-
ce the bottom segment of the
fuel meter and fuel level warning
indicator started flashing)
a self-diagnosis device
a clock
an ambient temperature display
an oil change indicator
a V-belt replacement indicator
TIP
Be sure to turn the key to “ON”
before using the “SELECT” and
“RESET” buttons.
When the key is turned to “ON”,
all of the display segments of the
multi-function display will appear
and then disappear, in order to
test the electrical circuit.
Odometer and tripmeter modes
Pushing the “SELECT” button swit-
ches the display between the odome-
ter mode “Odo” and the tripmeter
modes “Trip” in the following order:
Odo/Trip (top) Trip (bottom)/Trip
(top) Odo/Trip (top)When approximately 2.0 L (0.53 US
gal, 0.44 Imp.gal) of fuel remains in
the fuel tank, the bottom segment of
the fuel meter and fuel level warning
indicator will start flashing, and the
display will automatically change to
the fuel reserve tripmeter mode “Trip
F” and start counting the distance tra-
veled from that point. In that case,
pushing the “SELECT” button swit-
ches the display between the various
tripmeter and odometer modes in the
following order:
Trip F/Trip (top) Trip (bottom)/Trip
(top) Odo/Trip (top) Trip F/Trip

1. Fuel reserve tripmeter
To reset a tripmeter, select it by pus-
hing the “SELECT” button until “Trip”
or “Trip F” begins flashing (“Trip” or
“Trip F” will only flash for five
seconds). While “Trip” or “Trip F” is
flashing, push the “RESET” button for
at least one second. If you do not
reset the fuel reserve tripmetermanually, it will reset itself automati-
cally and the display will return to the
prior mode after refueling and trave-
ling 5 km (3 mi).
TIP
The display cannot be changed back
to “Trip F” after pushing the “RESET”
button.
Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear
towards “E” (Empty) as the fuel level
decreases. When the fuel level rea-
ches the bottom segment near “E”,
the fuel level warning indicator and
the bottom segment will flash. Refuel
as soon as possible.
Coolant temperature meter
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. The
coolant temperature varies with chan-
ges in the weather and engine load. Ifthe top segment and coolant tempe-
rature warning indicator flash, stop
the vehicle and let the engine cool.
(See page 6-33).
ECA10021
Do not continue to operate the
engine if it is overheating.
Oil change indicator “OIL”
This indicator flashes at the initial
1000 km (600 mi), then at 6000 km
(3500 mi) and every 6000 km (3500
mi) thereafter to indicate that the
engine oil should be changed.
After changing the engine oil, reset
the oil change indicator. (See page
6-10).
