WARNING
●Become 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 thoroughly
understand.
●Never start the engine or ope-
rate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of cons-
ciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
●For safety, always start the
engine with the centerstand
down.
EAU16561
Starting a cold engineECA10250
CAUTION:
See page 5-4 for engine break-in
instructions prior to operating the
vehicle for the first time.
1. Turn the key to “h”, and when
the oil level warning light comes
on, turn it to “f”.
ECA10240
CAUTION:
If the oil level warning light does
not come on, have a Yamaha dealer
check the electrical circuit.
2. Close the throttle completely.
3. While applying the front or rear
brake, start the engine by pus-hing the start switch or by pus-
hing the kickstarter lever down.
NOTE:
If the engine fails to start by pushing
the start switch, release the 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 5 seconds on any one
attempt. If the engine does not start
with the starter motor, try using the
kickstarter.
ECA11040
CAUTION:
For maximum engine life, never
accelerate hard when the engine is
cold!

Braking
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.
EWA10300
s s
WARNING
●Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
●Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching suchareas 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 bra-
king downhill can be very diffi-
cult.
EAU16820
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing 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
traffic lights or at railroad cros-
sings).

Engine break-in
There 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 following 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 themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAU17212
Parking
When parking, stop the engine, and
then remove the key from the main
switch.
EWA10310

WARNING
●Since the engine and exhaust
system can become very hot,
park in a place where pedes-
trians or children are not likely
to touch them.
●Do not park on a slope or on
soft ground, otherwise the
vehicle may overturn.
ECA10380
CAUTION:
Never park in an area where there
are fire hazards such as grass or
other flammable materials.

Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the follo-
wing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING
ON THE WEATHER, TERRAIN, GEO-
GRAPHICAL LOCATION, AND INDIVI-
DUAL USE, THE MAINTENANCE
INTERVALS MAY NEED TO BE
SHORTENED.

Periodic maintenance and lubrication chart
NOTE:
●The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK,
a mileage-based maintenance, is performed instead.
●From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
●Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.
