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
●
an ambient temperature display
●
an oil change indicator
●
a V-belt replacement indicator
TIP●
Be 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
and then disappear, in order to test
the electrical circuit.
Odometer and tripmeter modes
Pushing the “SELECT” button switches
the display between the odometer
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 indica-
tor will start flashing, and the display will
automatically change to the fuel re-
serve tripmeter mode “Trip F” and start
counting the distance traveled from that
point. In that case, pushing the “SE-
LECT” button switches the display be-
tween the various tripmeter and
odometer modes in the following order:
Trip F/Trip (top) → Trip (bottom)/Trip
(top) → Odo/Trip (top) → Trip F/Trip

To reset a tripmeter, select it by push-
ing 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 re-
serve tripmeter manually, it will reset it-self automatically and the display will
return to the prior mode after refueling
and traveling 5 km (3 mi).
TIPThe display cannot be changed back to
“Trip F” after pushing the “RESET” but-
ton.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 fuel level warn-
ing 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 chang-
es in the weather and engine load. If
the top segment and coolant tempera-ture warning indicator flash, stop the
vehicle and let the engine cool. (See
page 6-36.)

NOTICE
ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.Your Yamaha engine has been de-
signed to use premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a differentbrand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.

Catalytic converters This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING
EWA10862
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:●
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
●
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
●
Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.
●
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
