Fuel gauge
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 remaining fuel in
the tank reaches approximately 1.9 L, the
fuel level warning light will come on and
the multi-function display will
automatically change to the "Trip/Fuel"
mode. (See page 3-4 — 3-5 for details.).
If this occurs, refuel as soon as possible.
NOTE :
Do not allow the fuel tank to empty itself
completely.
EAUM0099*
Battery voltage/coolant
temperature gauge
When the key is turned to "", this
gauge indicates the battery voltage
level before the engine was stopped.
NOTE :
If the needle drops to the "9V" mark,
have a Yamaha dealer check the
battery.When the key is turned to "
", this
gauge indicates the coolant
temperature. If the needle reaches the
red zone, stop the scooter and allow
the engine to cool. (See page 6-17 for
details.)

Sidestand
The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
scooter 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 explanation
of the ignition circuit cut-off system.)
EW000044
The scooter must not be ridden with
the sidestand down, or if the
sidestand 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. Yamaha’s ignition circuit cut-
off system has been designed to
assist the operator in fulfilling the
responsibility 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 properly.

WARNINGEAU00337
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 sidestand
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.
EW000045
If a malfunction is noted, have a
Yamaha dealer check the system
before riding.

PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or
loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual
inspection, to check the following points before each ride.
EAU03439
Pre-operation check list

EAU01118
EW000129
•Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or
function that you do not
thoroughly understand.
•Never start the engine or
operate it in a closed area for
any length of time. Exhaust fu-
mes are poisonous, and
inhaling them can cause loss of
consciousness and death
within a short time. Always
make sure that there is
adequate ventilation.
•For safety, always start the
engine with the centerstand
down.
WARNING
EAU03843
Starting the engine
See page 5-4 for engine break-in ins-
tructions prior to operating the
vehicle for the first time.
In order for the ignition circuit cut-off
system to enable starting, the sidestand
must be up.
EW000054
•Before starting the engine,
check the function of the igni-
tion circuit cut-off system
according to the procedure
described on page 3-16.
•Never ride with the sidestand
down.1. Turn the key to "
" and make
sure that the engine stop switch
is set to "

NOTE :
If the engine does not start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to
preserve the battery. Do not crank the
engine more than 10 seconds on any
one attempt. If the engine does not
start, try with the throttle open 1/8 turn.
ECA00045
For maximum engine life, never
accelerate hard when the engine is
cold!

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
•Avoid high engine speeds during
acceleration.
•Avoid high engine speeds with no
load on the engine.
•Turn the engine off instead of
letting it idle for an extended
length of time (e.g., in traffic jams,
at traffic lights or at railroad
crossings).
EAU01128
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1,600 km. For this
reason, you should read the following
material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,600 km. The various parts in the
engine wear and polish themselves to
the correct operating clearances.
During this period, prolonged full-
throttle operation or any condition that
might result in engine overheating must
be avoided.
EAU03845*
0 — 1,000 km
Avoid prolonged operation above 1/3
throttle.
1,000 — 1,600 km
Avoid prolonged operation above 1/2
throttle.
ECA00138
After 1,000 km of operation, be sure
to replace the engine oil and final
transmission oil.
1,600 km and beyond
The vehicle can now be operated
normally.
EC000049
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
