sparks, open flames, or other
sources of ignition such as the pi-
lot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. Stop
filling when the fuel reaches the
bottom of the filler tube. Because
fuel expands when it heats up, heat
from the engine or the sun can
cause fuel to spill out of the fuel
tank.
3. Wipe up any spilled fuel immedi-
ately.
NOTICE:
Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may dete-
riorate painted surfaces or plas-
tic parts.

4. Be sure to securely close the fuel
tank cap.

WARNING
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gasoline
by mouth. If you should swallowsome gasoline or inhale a lot of gaso-
line 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.

Read the Owner’s Manual carefully to
become familiar with all controls. If there
is a control or function you do not un-
derstand, ask your Yamaha dealer.
EWA10271
WARNING
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.

TIP
This model is equipped with a lean angle
sensor to stop the engine in case of a
turnover. To start the engine after a turn-
over, be sure to turn the main switch to
“OFF” and then to “ON”. Failing to do so
will prevent the engine from starting
even though the engine will crank when
pushing the start switch.

NOTICEThe engine trouble warning light and
coolant temperature warning light
should come on for a few seconds,
then go off. If these warning lights do
not go off, have a Yamaha dealer check
their electrical circuits.2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the front
or rear brake.
NOTICE:
For maxi-
mum engine life, never acceler-
ate hard when the engine is
cold!
[ECA11041]
If the engine does not start, release
the start switch, wait a few sec-
onds, and then try again. Each
starting attempt should be as short
as possible to preserve the battery.
Do not crank the engine more than
5 seconds on any one attempt. If
the engine does not start with the
starter motor, try using the
kickstar ter.

WARNING
● ●● ●
●
Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.
● ●● ●
●
Railroad 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 cau-
tion.
● ●● ●
●
Keep in mind that braking on a
wet road is much more difficult.
● ●● ●
●
Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.
EAU16761
Starting offTIP
Before starting off, allow the engine to
warm up.1. While pulling the rear brake lever
with your left hand and holding the
grab bar with your right hand, push
the scooter off the centerstand.
2. Sit astride the seat, and then ad-
just the rear view mirrors.
3. Switch the turn signals on.
4. Check for oncoming traffic, and
then slowly turn the throttle grip (on
the right) in order to take off.

EAU16830
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances. Dur-
ing this period, prolonged full-throttle
operation or any condition that might
result in engine overheating must be
avoided. Fuel consumption, tips for reducing
Engine break-in
EAU16820
Tips for reducing fuel con-
sumptionFuel 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 let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16951
0 ~ 150 km (0 ~ 90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for five to
ten minutes.Vary the engine speed from time to time.
Do not operate the engine at one set
throttle position.
150 ~ 500 km (90 ~ 300 mi)
Avoid prolonged operation above 1/2
throttle.
Rev the engine freely through the gears,
but do not use full throttle at any time.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above 3/4
throttle.
NOTICE:
After 1000 km (600
mi) of operation, the engine oil must
be changed and the oil strainer
cleaned.
[ECA10351]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.

NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
