SAFETY INFORMATION
1-3
1Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing car-
bon monoxide can cause headaches,
dizziness, drowsiness, nausea, confu-
sion, and eventually death.
Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be
present even if you do not see or smell
any engine exhaust. Deadly levels of
carbon monoxide can collect rapidly
and you can quickly be overcome and
unable to save yourself. Also, deadly
levels of carbon monoxide can linger
for hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poison-
ing, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.
●
Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
●
Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
●
Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution of
the scooter is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or accesso-
ries to your scooter. Use extra care
when riding a scooter that has added
cargo or accessories. Here, along with
the information about accessories be-
low, are some general guidelines to fol-
low if loading cargo to your scooter:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.
When loading within this weight limit,
keep the following in mind:
●
Cargo and accessory weight
should be kept as low and close to
the scooter as possible. Securely
pack your heaviest items as close
to the center of the vehicle as pos-
sible and make sure to distribute
the weight as evenly as possible
on both sides of the scooter to min-
imize imbalance or instability.
●
Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the scooter before
riding. Check accessory mounts
and cargo restraints frequently.
Properly adjust the suspension
for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure of your tires.
Never attach any large or heavy
items to the handlebar, front
fork, or front fender. Such items
can create unstable handling or
a slow steering response.
●
This vehicle is not designed to
pull a trailer or to be attached to
a sidecar.
Maximum load:
185 kg (408 lb)

3hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.
TIPThe self-diagnosis device also detects
problems in the immobilizer system cir-
cuits. If the immobilizer system is not
working correctly, the indicator light will
start flashing a pattern when the key is
turned to “ON”. When this occurs, have
a Yamaha dealer check the self-diag-
nosis system. However, if the indicator
light slowly flashes five times, and then
quickly flashes two times repeatedly,
this error could be caused by signal in-
terference. If this occurs, try the follow-
ing.1. Use the code re-registering key to
start the engine.TIPMake sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the engine
from starting.
2. If the engine starts, turn it off, and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the stan-
dard keys re-registered.

WARNING
EWA10241
The vehicle must not be ridden with
the sidestand down, or if the side-
stand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly and have a
Yamaha dealer repair it if it does not
function properly.
EAU45052
Ignition circuit cut-off system The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.●
It prevents starting when the side-
stand is up, but neither brake is ap-
plied.
●
It prevents starting when either
brake is applied, but the sidestand
is still down.
●
It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.
