Fuel gauge
1. Fuel gauge
2. Fuel level warning light “ ”
The fuel gauge indicates the amount
of fuel in the fuel tank. The needle
moves towards “E” (Empty) as the
fuel level decreases. When the remai-
ning fuel in the tank reaches approxi-
mately 2 L (0.53 US gal) (0.44
Imp.gal), the fuel level warning light
will come on and the multi-function
display will automatically change to
the “Trip/fuel” mode. (See page 3-6.)
If this occurs, refuel as soon as possi-
ble.
NOTE:
Do not allow the fuel tank to empty
itself completely.EAU12171
Coolant temperature gauge
1. Red zone
2. Coolant temperature gauge
With the key in the “ON” position, the
coolant temperature gauge indicates
the temperature of the coolant. The
coolant temperature varies with chan-
ges in the weather and engine load. If
the needle reaches or enters the red
zone, stop the vehicle and let the
engine cool. (See page 6-34.)

Multi-function display
1. “MODE” button
2. Multi-function display
3. “SET” button
The multi-function display is equip-
ped with the following:
●an odometer (which shows the
total distance traveled)
●two tripmeters (which show the
distance traveled since they were
last set to zero, the time passed
since the tripmeters were set to
zero, and the average speed tra-
veled during this time)
●a fuel reserve tripmeter (which
shows the distance traveled sin-
ce the fuel level warning light
came on)
●a clock
●an ambient temperature display
●an oil change indicator (which
comes on when the engine oil
should be changed)
NOTE:
●For the UK, the distance traveled
is displayed in miles and the tem-
perature reading is displayed in
ºF.
●For other countries, the distance
traveled is displayed in kilome-
ters and the temperature reading
is displayed in ºC.
Odometer and tripmeter modes
Pushing the “MODE” button switches
the display between the odometer
mode “Total” and the tripmeter
modes “Trip” in the following order:
Total
Trip 1 Trip 2 Trip/fuel
Total
1. Total
2. Trip 1
3. Trip 2
4. Trip/Fuel
NOTE:
●The Trip/fuel odometer is only
activated if the fuel level warning
light comes on.
●The Trip 2 odometer is automati-
cally reset after turning the key to
“OFF” and two hours have pas-
sed.
Pushing the “SET” button when in the
tripmeter mode switches the display
between the different tripmeter func-
tions in the following order:

2. Negative symbol “ – ”
3. Ambient temperature
This display shows the ambient tem-
perature from –30 °C (–86 °F) to 50 °C
(122 °F).
The frost warning indicator “ ”
automatically comes on if the tempe-
rature is lower than 3 °C (37.4 °F).Oil change indicator “OIL”
1. Oil change indicator “OIL”
The engine oil should be changed
when this indicator comes on. The
indicator stays on until it is reset. After
changing the engine oil, reset the indi-
cator as follows.
1. While holding the “MODE” and
“SET” buttons pushed, turn the
key to “ON”.
2. Continue holding the “MODE”
and “SET” buttons pushed for
two to five seconds.
3. Release the buttons and the oil
change indicator will go off.
NOTE:
●The oil change indicator will come
on at the initial 1000 km (600 mi),
5000 km (3000 mi) after the initial
1000 km (600 mi) and every 6000
km (3600 mi) thereafter.
●If the engine oil is changed befo-
re the oil change indicator comes
on (i.e. before the periodic oil
change interval has been rea-
ched), the indicator must be reset
after the oil change for the next
periodic oil change to be indica-
ted at the correct time. After
resetting, the indicator will come
on for two seconds. If the indica-
tor does not come on, repeat the
procedure.

NOTE:
Even if the key is turned from “ON” to
“OFF” with the hazard lighting on, the
hazard lighting will continue to flash
regardless of the hazard switch posi-
tion. To cancel the hazard lighting, the
key must be turned to “ON” and the
hazard switch must be set to the “h”
position.
The hazard lighting is used in case of
an emergency or to warn other drivers
when your scooter is stopped where
it might be a traffic hazard.

CAUTION:
Do not use the hazard light for an
extended length of time, otherwise
the battery may discharge.

CAUTION:
Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfa-
ces or plastic parts.
EAU33500
ECA11400
CAUTION:
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 sys-
tem.
Your Yamaha engine has been desig-
ned to use regular unleaded gasoline
with a research octane number of 91or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. 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
The exhaust system is hot after
operation. Make sure that the
exhaust system has cooled down
before doing any maintenance
work.
ECA10700
CAUTION:
The following precautions must be
observed to prevent a fire hazard or
other damages.
●Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.
●Never park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
●Do not allow the engine to idle
too long.

The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.

NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain
situations. (See further down for an

WARNING
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.
EAU15372
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
●It prevents starting when the
sidestand is up, but neither brake
is applied.
●It prevents starting when either
brake is applied, but the sides-
tand is still down.
●It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.
