cCUse only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
Your Yamaha engine has been
designed to use regular unleaded
gasoline with a research octane num-
ber of 91 or 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 mainte-
nance costs.

wThe 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 con-
tact 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 rais-
ing 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.
EAU00337
Ignition circuit cut-off
systemIgnition circuit cut-off systemThe ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the follow-
ing functions.
8It prevents starting when the
sidestand is up, but neither brake
is applied.
8It prevents starting when either
brake is applied, but the side-
stand is still down.
8It 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.

wIf 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 unexpect-
edly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leak-
age or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thor-
ough visual inspection, to check the following points before each ride.

w8Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or func-
tion that you do not thorough-
ly understand.
8Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
8For safety, always start the
engine with the centerstand
down.
8When the centerstand is down
and the engine is idling, keep
your hands and feet away from
the rear wheel.

instructions prior to operating the
vehicle for the first time.In order for the ignition circuit cut-off
system to enable starting, the side-
stand must be up.

w8Before starting the engine,
check the function of the igni-
tion circuit cut-off system
according to the procedure
described on page 3-16.
8Never ride with the sidestand
down.
1. Turn the key to “ON” and make
sure that the engine stop switch
is set to “#”.
2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the
front or rear brake.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 possi-
ble to preserve the battery. Do not
crank the engine more than 10 sec-
onds on any one attempt. If the
engine does not start, try with the
throttle open 1/8 turn.

BrakingBraking1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.
EW000057
w8Avoid braking hard or sudden-
ly (especially when leaning
over to one side), otherwise
the scooter may skid or over-
turn.
8Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore,
slow down when approaching
such areas and cross them
with caution.
8Keep in mind that braking on a
wet road is much more diffi-
cult.
8Ride slowly down a hill, as
braking downhill can be very
difficult.

Tips for reducing fuel
consumptionFuel consumption, tips for reducingFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
8Thoroughly warm up the engine.
8Avoid high engine speeds during
acceleration.
8Avoid high engine speeds with
no load on the engine.
8Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cross-
ings).
