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.
EAUM1210
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 “ON”.
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 fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank theengine more than 10 seconds on any
one attempt.
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).

The annual checks must be performed every year, except if a kilometer-based maintenance is performed
instead.
From 50000 km, repeat the maintenance intervals starting from 10000 km.
