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 whenriding a scooter that has added cargo or
accessories. Here, along with the infor-
mation about accessories below, are
some general guidelines to follow if load-
ing 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.
Maximum load:
177 kg (390 lb)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 possible
and make sure to distribute the
weight as evenly as possible on
both sides of the scooter to mini-
mize 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-
adjustable models only), and
check the condition and
pressure 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.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine

Further safe-riding points●
Make 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 stop-
ping on a wet surface.
●
Slow down as you approach a cor-
ner or turn. Once you have com-
pleted 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 become
extremely slippery when wet. Slow
down and cross them with caution.
Keep the scooter upright, otherwise
it could slide out from under you.
●
The brake lining could get wet when
you wash the scooter. After wash-
ing the scooter, check the brakes
before riding.
●
Always wear a helmet, gloves, trou-
sers (tapered around the cuff and
ankle so they do not flap), and a
bright colored jacket.
●
Do not carry too much luggage on
the scooter. An overloaded scooter
is unstable.

tric failure could result, which could
cause a dangerous loss of lights or
engine power.
Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to provide
the best combination of handling, brak-
ing, and comfort. Other tires, rims, sizes,
and combinations may not be appropri-
ate. Refer to page 6-12 for tire specifi-
cations and more information on replac-
ing your tires.
