OPERATION AND IMPORTANT RIDING POINTS
EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING

EWA10271
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.
EAU48020
TIP

This model is equipped with a lean an-
gle sensor to stop the engine in case of
a turnover. In this case, the multi-func-
tion display indicates error code 30, but
this is not a malfunction. Turn the key to
“OFF” and then to “ON” to clear the er-
ror code. Failing to do so will prevent
the engine from starting even though
the engine will crank when pushing the
start switch.
EAU36512
Starting the engine
NOTICE

ECA10250
See page 5-4 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.
In order for the ignition circuit cut-off
system to enable starting, the side-
stand must be up.
See page 3-22 for more information.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
The following warning lights, indi-
cator light and indicators should
come on for a few seconds, then
go off.

Engine trouble warning light

ABS warning light (for ABS mod-
els)

Immobilizer system indicator light

V-belt replacement indicator

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, re-
lease the start switch, wait a few
seconds, and then try again. Each
starting attempt should be as short
as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one at-
tempt.
EAU45091
Starting off
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.
5. Switch the turn signals off.
EAU16780
Acceleration and deceleration
The speed can be adjusted by opening
and closing the throttle. To increase the
speed, turn the throttle grip in direction
(a). To reduce the speed, turn the throt-
tle grip in direction (b).

Braking
WARNING

EWA10300

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.

EAU16820
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 let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).

EAU16841
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 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
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU34321
0–1000 km (0–600 mi)
Avoid prolonged operation above 4000
r/min.
NOTICE:
After 1000 km (600
mi) of operation, be sure to replace
the engine oil, final transmission oil
and the oil filter element.

[ECA12931]

1000–1600 km (600–1000 mi)
Avoid prolonged operation above 6000
r/min.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE

ECA10310

Keep the engine speed out of
the tachometer red zone.

If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.
EAU17213
Parking
When parking, stop the engine, and
then remove the key from the main
switch.
WARNING

EWA10311

Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.

Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the
risk of a fuel leak and fire.

Do not park near grass or other
flammable materials which
might catch fire.

PERIODIC MAINTENANCE AND ADJUSTMENT
EAU17241
Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the vehi-
cle owner/operator. The most important
points of vehicle inspection, adjust-
ment, and lubrication are explained on
the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, depending on the
weather, terrain, geographical location,
and individual use, the maintenance in-
tervals may need to be shortened.
WARNING

EWA10321
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer perform
service.
WARNING

EWA15121
Turn off the engine when performing
maintenance unless otherwise
specified.

A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
fires.

Running the engine while ser-
vicing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-1 for more in-
formation about carbon monox-
ide.
EAU17502
Owner’s tool kit
The owner’s tool kit is located inside the
rear storage compartment. (See
page 3-19.)
Pull up the storage compartment mat,
and then remove the owner’s tool kit.
The service information included in this
manual and the tools provided in the
owner’s tool kit are intended to assist
you in the performance of preventive
maintenance and minor repairs. How-
ever, additional tools such as a torque
wrench may be necessary to perform
certain maintenance work correctly.

TIP


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 50000 km (30000 mi), repeat the maintenance intervals starting from 10000 km (6000 mi).

Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technical
skills.

TIP


Engine air filters and V-belt air filter

This model’s engine air filters are equipped with disposable oil-coated paper elements, which must not be cleaned
with compressed air to avoid damaging them.

The engine air filter elements need to be replaced and the V-belt air filter element needs to be serviced more frequent-
ly when riding in unusually wet or dusty areas.

Hydraulic brake service

Regularly check and, if necessary, correct the brake fluid level.

Every two years replace the internal components of the brake master cylinders and calipers, and change the brake
fluid.

Replace the brake hoses every four years and if cracked or damaged.
