Be a Responsible Owner
As the vehicle’s owner, you are res-
ponsible for the safe and proper ope-
ration of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are
dependent upon the use of proper
riding techniques as well as the
expertise of the operator. Every ope-
rator should know the following requi-
rements before riding this scooter.
He or she should:
Obtain thorough instructions
from a competent source on all
aspects of scooter operation.
Observe the warnings and main-
tenance requirements in this
Owner’s Manual.
Obtain qualified training in safe
and proper riding techniques.
Obtain professional technical
service as indicated in this
Owner’s Manual and/or when
made necessary by mechanical
conditions.
Safe Riding
Perform the pre-operation checkseach time you use the vehicle to
make sure it is in safe operating con-
dition. Failure to inspect or maintain
the vehicle properly increases the
possibility of an accident or equip-
ment damage. See page 4-1 for a list
of pre-operation checks.
This scooter is designed to carry
the operator and a passenger.
The failure of motorists to detect
and recognize scooters in traffic
is the predominating cause of
automobile/scooter accidents.
Many accidents have been cau-
sed by an automobile driver who
did not see the scooter. Making
yourself conspicuous appears to
be very effective in reducing the
chance of this type of accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you
are approaching and passing
through intersections, since
intersections are the most
likely places for scooter acci-
dents to occur.• Ride where other motorists can
see you. Avoid riding in anot-
her motorist’s blind spot.
Many accidents involve inexpe-
rienced operators. In fact, many
operators who have been invol-
ved in accidents do not even
have a current driver’s license.
• Make sure that you are quali-
fied and that you only lend your
scooter to other qualified ope-
rators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you prac-
tice riding your scooter where
there is no traffic until you have
become thoroughly familiar
with the scooter and all of its
controls.
Many accidents have been cau-
sed by error of the scooter ope-
rator. A typical error made by the
operator is veering wide on a turn
due to excessive speed or under-
cornering (insufficient lean angle
for the speed).

have a Yamaha dealer check the self-
diagnosis system.
The electrical circuit of the warning
light can be checked by turning the
key to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to
“ON”, or if the warning light remains
on, have a Yamaha dealer check the
electrical circuit.
TIP
This warning light will come on when
the key is turned to “ON” and the start
switch is pushed, but this does not
indicate a malfunction.

Immobilizer system indicator light
The electrical circuit of the indicator
light can be checked by turning the
key to “ON”. The indicator lightshould come on for a few seconds,
and then go off.
If the indicator light does not come on
initially when the key is turned to
“ON”, or if the indicator light remains

When the key is turned to “OFF” and
30 seconds have passed, the indica-
tor light will start flashing indicating
the immobilizer system is enabled.
After 24 hours have passed, the indi-
cator light will stop flashing, however
the immobilizer system is still ena-
bled.

When approximately 1.7 L (0.45 US
gal, 0.37 Imp.gal) of fuel remains in
the fuel tank, the bottom segment of
the fuel meter and fuel level warning
indicator will start flashing, and the
display will automatically change to
the fuel reserve tripmeter mode “Trip

TIP
The display cannot be changed back
to “Trip F” after pushing the “RESET”
button.
Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel meter disappear

decreases. When the fuel level rea-
ches the bottom segment near “E”,
the fuel level warning indicator and
the bottom segment will flash. Refuel
as soon as possible.
Coolant temperature meter
