The multi-function meter unit is
equipped with the following:
a speedometer
a fuel meter
a clock
an outside air temperature display
an odometer
two tripmeters
a fuel reserve tripmeter
an oil change tripmeter
a V-belt replacement tripmeter
an oil change indicator
a V-belt replacement indicatorTIPBe sure to turn the key to “ON” be-
fore using the “SELECT” and “RE-
SET” buttons.
For the UK: press the “SELECT”
button for one second to switch
the speedometer and odome-
ter/tripmeter displays between ki-
lometers and miles.
If the coolant temperature warning
light and engine trouble warning
light remain on during the initial
display mode, have the battery
charged by a Yamaha dealer.
Speed ometer
The speedometer shows the vehicle’s
traveling speed. Fuel meter
The fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear to-
wards “E” (empty) as the fuel level
decreases. When the bottom segment
of the fuel meter and fuel level warning
indicator “ ” start flashing, refuel as
soon as possible. When the key is
turned to “ON”, all of the display seg-
ments of the fuel meter will appear for
a few seconds, and then the fuel meter
shows the actual fuel level.1. Speedometer

3 The tripmeters show the distance trav-
eled since they were last set to zero.
Push the “SELECT” button to switch
the display between the odometer
mode “ODO”, the tripmeter modes
“TRIP 1” and “TRIP 2”, the oil change
tripmeter mode “OIL TRIP” and the V-
belt replacement tripmeter mode
“BELT TRIP” in the following order:
ODO
→ TRIP 1 → TRIP 2 → OIL TRIP
→ BELT TRIP → ODO
When approximately 1.6 L (0.42 US
gal, 0.35 Imp.gal) of fuel remains in the
fuel tank, the bottom segment of the
fuel meter and fuel level warning indi-
cator will start flashing, and the display
will automatically change to the fuel re-
serve tripmeter mode “F” and start
counting the distance traveled from
that point. In this case, pushing the
“SELECT” button switches the display
in the following order:
F → TRIP 1 → TRIP 2 → OIL TRIP →
BELT TRIP → ODO → F
To reset tripmeters 1, 2, or the fuel re-
serve tripmeter, select the tripmeter
you want to reset with the “SELECT”
button, and then push the “RESET”
button for one second. If you do not re- set the fuel reserve tripmeter manually,
it will reset automatically and the dis-
play will return to the prior mode after
refueling and traveling 5 km (3 mi).
To reset the oil change tripmeter or V-
belt replacement tripmeter, select it by
pushing the “SELECT” button, and
then push the “RESET” button for
three to four seconds.
TIP
The odometer will lock at 999999.
The tripmeters will reset and con-
tinue counting after 9999.9 is
reached.Oil chan ge in dicator “OIL CHANGE” This indicator will come on at the initial
1000 km (600 mi), then at 4000 km
(2500 mi) and every 4000 km (2500 mi)
thereafter to indicate that the engine oil
should be changed.
After changing the engine oil, reset the
oil change indicator and the oil change
tripmeter. To reset them both, select
the oil change tripmeter, and then push
the “RESET” button for one second.
While “OIL CHANGE” is flashing, push
the “RESET” button for three seconds.
The oil change tripmeter will be reset
and the oil change indicator will go off.
If the engine oil is changed before the
oil change indicator comes on (i.e., be-
fore the periodic oil change interval has
been reached), the oil change tripmeter
must be reset for the next periodic oil
change to be indicated at the correct
time.1. Oil change indicator “OIL CHANGE”

3 Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
