Safety information

1Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to pro-
vide the best combination of handling,
braking, and comfort. Other tires, rims,
sizes, and combinations may not be
appropriate. Refer to page 9-19 for tire
specifications and more information on
replacing your tires.
Transporting the Scooter
Be sure to observe following instruc-
tions before transporting the scooter in
another vehicle.
Remove all loose items from the
scooter.
Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
Secure the scooter with tie-downs
or suitable straps that are at-
tached to solid parts of the scoot-
er, such as the frame or upper
front fork triple clamp (and not, for
example, to rubber-mounted han-
dlebars or turn signals, or parts
that could break). Choose the lo-cation for the straps carefully so
the straps will not rub against
painted surfaces during transport.
The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the
scooter will not bounce exces-
sively during transport.
EAU57600
Further safe-riding pointsBe sure to signal clearly when
making turns.
Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when
stopping on a wet surface.
Slow down as you approach a
corner or turn. Once you have
completed a turn, accelerate
slowly.
Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.
The brake pads or linings could
get wet when you wash the scoot-
er. After washing the scooter,
check the brakes before riding.

6Do not remove or alter the O2 sen-
sor, air induction system, or ex-
haust parts (catalysts or EXUP,
etc.).
Maintain proper V-belt and drive
belt (if equipped).
Maintain correct tire pressure.
Do not operate the vehicle in an
extreme manner. For example, re-
peated or excessive opening and
closing of the throttle, racing,
burnouts, wheelies, etc.

ABS warning light “ ”
This warning light comes on when the
vehicle is first turned on, and goes off
after starting riding. If the warning light
comes on while riding, the anti-lock
brake system may not work correctly.
WARNING
EWA16043
If the ABS warning light does not
turn off after reaching 10 km/h (6
mi/h), or if the warning light comes
on while riding:
Use extra caution to avoid pos-
sible wheel lock during emer-
gency braking. Have a Yamaha dealer check
the vehicle as soon as possible.
TIPThe ABS warning light may come on
while revving the engine with the vehi-
cle on its centerstand, but this does
not indicate a malfunction.
EAU88930
Traction control system indicator
light “ ”
This indicator light will flash when trac-
tion control has engaged.
If the traction control system is turned
off, this indicator light will come on.
(See page 6-12.)TIPWhen the vehicle is turned on, the light
should come on for a few seconds and
then go off. If the light does not come
on, or if the light remains on, have a
Yamaha dealer check vehicle.
EAUN2770
Smart key system indicator
light “ ”
This indicator light communicates the
status of the smart key system. When
the smart key system is operating nor-
mally, this indicator light will be off. If
there is an error in the smart key sys-
tem, the indicator light will flash. The
indicator light will also flash when com-
munication between the vehicle and
smart key takes place and when cer-
tain smart key system operations are
carried out.
EAUN2830
Stop and Start System indicator
light “ ”
This indicator light comes on when the
Stop and Start System activates. The
indicator light will flash when the en-
gine is automatically stopped by the
Stop and Start System.TIPEven if the Stop and Start Switch is set
to Ž, this indicator light may not
come on. (See page 4-1.)

Front brake leverThe front brake lever is located on the
right side of the handlebar. To apply
the front brake, pull this lever toward
the throttle grip.

left side of the handlebar. To apply the
rear brake, pull this lever toward the
handlebar grip.
EAU53142
ABSThe Yamaha ABS (Anti-lock Brake
System) features a dual electronic con-
trol system, which acts on the front and
rear brakes independently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake levers. In this situa-
tion, continue to apply the brakes and
let the ABS work; do not “pump” the
brakes as this will reduce braking ef-
fectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.
On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer with
the ABS than without.The ABS is monitored by an ECU,
which will revert the system to conven-
tional braking if a malfunction occurs.

TIPThe ABS performs a self-diagno-
sis test each time the vehicle first
starts off after the key is turned to
“ON” and the vehicle has traveled
at a speed of 10 km/h (6 mi/h) or
higher. During this test, a “click-
ing” noise can be heard from the
front of the vehicle, and if either
brake lever is even slightly ap-
plied, a vibration can be felt at the
lever, but these do not indicate a
malfunction.
This ABS has a test mode which
allows the owner to experience
the pulsation at the brake levers
when the ABS is operating. How-
ever, special tools are required, so
please consult your Yamaha deal-
er.NOTICE
ECA20100
Be careful not to damage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.
EAUN2810
Traction control systemThe traction control system (TCS)
helps maintain traction when acceler-
ating on slippery surfaces, such as un-
paved or wet roads. If sensors detect
that the rear wheel is starting to slip
(uncontrolled spinning), the traction
control system assists by regulating
engine power until traction is restored.
When traction control has engaged,
the “ ” indicator light will flash. You
may notice changes in engine re-
sponse or exhaust sound.
WARNING
EWA18860
The traction control system is not a
substitute for riding appropriately
for the conditions. Traction control
cannot prevent loss of traction due
to excessive speed when entering
turns, when accelerating hard at a
sharp lean angle, or while braking,
and cannot prevent front wheel slip-
ping. As with any vehicle, approach
surfaces that may be slippery with
caution and avoid especially slip-
pery surfaces.
