3The multi-function meter unit is
equipped with the following:
a speedometer
a tachometer
a fuel meter
a clock
an odometer and tripmeter display
a multi-function display
a coolant temperature meter
TIPBe sure to turn the key to “ON” be-
fore using the “Select”, “Reset”,
“TRIP” 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 and odometer will then perform
a display check and a welcome
message will scroll across the
multi-function display.
For the UK, traveling speed, dis-
tance traveled, and fuel consump-
tion measurements can be
displayed in kilometer or mileage
based units. To switch between
miles and kilometers; hold the“SELECT” switch pushed, turn the
main switch to “ON”, and keep the
“SELECT” switch pushed for an
additional 8 seconds.
For other countries, traveling
speed, distance traveled and fuel
consumption measurements are
displayed in kilometer base units.
Speedometer
The speedometer shows the riding
speed.
Tachometer
The electric tachometer allows the rid-
er to monitor the engine speed and
keep it within the ideal power range.
NOTICE
ECAM1150
Do not operate the engine in the ta-
chometer high-rpm zone.
High-rpm zone: 10000 r/min and
aboveFuel 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.

To set the clock:
1. Push the “SELECT” button for 3
seconds, and the hour digits will
start flashing.
2. Use the “SELECT” button to set
the hours.
3. Push the “SELECT” button for 3
seconds, and the minute digits will
start flashing.
4. Use the “SELECT” button to set
the minutes.
5. Push the “SELECT” button for 3
seconds to complete setting the
clock.Odometer and tripmeter display
The odometer and tripmeter display is
equipped with the following:
a tripmeter (which shows the dis-
tance traveled since last set to ze-
ro)
a time tripmeter (which shows the
elapsed riding time since last set
to zero)
a fuel reserve tripmeter (which
shows the distance traveled since
the fuel level warning light came
on)
an oil change tripmeter (which
shows the distance traveled since
the last engine oil change)a V-belt replacement tripmeter
(which shows the distance trav-
eled since the last V-belt replace-
ment)
Pushing the “TRIP” button switches
the display between the odometer
mode and the various tripmeter modes
in the following order:
Odo (odometer) → Trip (tripmeter) →
Trip Time (time tripmeter) → Oil (oil
change tripmeter) → V-Belt (v-belt re-
placement tripmeter) → Odo (odome-
ter)
When approximately 2.5 L (0.66 US
gal, 0.55 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 “TRIP” button
switches the display between the vari-
ous tripmeter and odometer modes in
the following order:
Odo → Trip → Trip Time → F Trip (fuel
reserve tripmeter) → Oil Trip → V-Belt
Trip → Odo

distance traveled from the first run or
when the last reset was done.
To reset a tripmeter, select it by push-
ing the “TRIP” button until “Trip, Trip
Time, F Trip” is displayed. While “Trip,
Trip Time, F Trip” is displayed, push
the “TRIP” button for 3 seconds. If you
do not reset the fuel reserve tripmeter
manually, it will reset itself automatical-
ly and the display will return to the prior
mode after refueling and traveling 5 km
(3 mi).
TIPThe display cannot be changed back
Oil change indicator “Oil”
This indicator flashes at the initial 1000
km (600 mi), then at 5000 km (3000 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.
To reset the oil change indicator
1. Turn the key to “ON”.2. Push the “TRIP” button until “Oil”
(oil change tripmeter) is displayed
in the odometer and trip meter
display. While “Oil” is displayed,
push the “RESET” button for at
least 3 seconds. The oil change
tripmeter value will flash.
3. Hold the “RESET” button pushed
for 15 to 20 seconds.4. Release the “RESET” button, and
the oil trip value will reset to zero.
TIPIf 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 indicator must be
reset after the oil change for the next
periodic oil change to be indicated at
the correct time. To reset the oil
change indicator before the periodic oil
change interval has been reached, fol-
low the above procedure.The electrical circuit of the indicator
can be checked according to the fol-
lowing procedure.

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.

4. Be sure to securely close the fuel
tank cap.
WARNING
EWA15152
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gasoline
by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in
your eyes, see your doctor immedi-ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.
EAU54601
NOTICE
ECA11401
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 gas-
oline with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a differentbrand. Use of unleaded fuel will extend
spark plug life and reduce mainte-
nance costs.
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.
