TachometerThe electric tachometer allows the rid-
er to monitor the engine speed and
keep it within the ideal power range.
When the key is turned to “ON”, the ta-
chometer needle will sweep once
across the r/min range and then return
to zero r/min in order to test the electri-
cal circuit.NOTICE

Multi-function display
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 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 since
the bottom segment of the fuel
meter and fuel level warning indi-
cator started flashing)
a self-diagnosis device
a clock

TIPBe sure to turn the key to “ON” be-
fore using the “SELECT” and “RE-
SET” buttons.
When the key is turned to “ON”, all
of the display segments of the
multi-function display will appear
one after the other and then disap-
pear, in order to test the electrical
circuit.
For the UK, the distance traveled
is displayed in miles and the tem-
perature reading is displayed in
°C.
For other countries, the distance
traveled is displayed in kilometers
and the temperature reading is
displayed in °C.Odometer and tripmeter modes
Pushing the “SELECT” button switch-
es the display between the odometer
mode “Odo” and the tripmeter modes
“Trip” in the following order:
Odo → Trip 1 → Trip 2 → OdoWhen 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 will start flashing, and the
display will automatically change to the
fuel reserve tripmeter mode “Trip F”
and start counting the distance trav-
eled from that point. In that case, push-
ing the “SELECT” button switches the
display between the various tripmeter
and odometer modes in the following
order:
Trip F → Trip 1 → Trip 2 → Odo → Trip
F
To reset a tripmeter, select it by push-
ing the “SELECT” button until “Trip” or
“Trip F” , push the “RESET” button for
at least one second. If you do not resetthe fuel reserve tripmeter manually, it
will reset itself automatically and the
display will return to the prior mode af-
ter refueling and traveling 5 km (3 mi).
TIPThe display cannot be changed back
button.Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of fuel
in the fuel tank. The display segments
of the fuel meter disappear towards
“E” (Empty) as the fuel level decreases.
When the fuel level reaches the bottom
segment near “E”, 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
changes in the weather and engine
load. If the top segment and coolant
temperature “C” “H” indicator flash,
stop the vehicle and let the engine

FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.1. Before refueling, turn off the en-
gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or
the sun can cause fuel to spill out
of the fuel tank.3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately
wipe off spilled fuel with a clean,
dry, soft cloth, since fuel may
deteriorate painted surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel
tank cap.
WARNING
EWA15152
Gasoline is poisonous and can cau-
se injury or death. Handle gasoline
with care. Never siphon gasoline by
mouth. If you should swallow some
gasoline or inhale a lot of gasoline
vapor, or get some gasoline in your
eyes, see your doctor immediately. Ifgasoline spills on your skin, wash
with soap and water. If gasoline
spills on your clothing, change your
clothes.
