TABLE OF CONTENTS

Do not run engine outdoors whe-
re 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 accessories to your scooter. Use
extra care when riding a scooter that
has added cargo or accessories.
Here, along with the information
about accessories below, are some
general guidelines to follow 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. Secu-
rely pack your heaviest items as
close to the center of the vehicle
as possible and make sure to dis-
tribute the weight as evenly as
possible on both sides of the
scooter to minimize imbalance or
instability.
Shifting weights can create a
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the scooter
before riding. Check accessory
mounts and cargo restraints fre-
quently.
Properly adjust the suspension
for your load (suspension-
adjustable 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 unstablehandling or a slow steering res-
ponse.
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
Yamaha accessories, which are avai-
lable only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection
to Yamaha manufacture parts and
accessories or offer other modifica-
tions for Yamaha vehicles. Yamaha is
not in a position to test the products
that these aftermarket companies
produce. Therefore, Yamaha can neit-
her endorse nor recommend the use
of accessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.

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.
The self-diagnosis device also
detects problems in the immobilizer
system circuits. (See page 3-6 for an
explanation of the self-diagnosis
device.)

Self-diagnosis device
This model is equipped with a self-
diagnosis device for various electrical
circuits.
If a problem is detected in any of tho-
se circuits, the multi-function display
will indicate an error code.
If the multi-function display indicates
such an error code, note the code
number, and then have a Yamaha
dealer check the vehicle.
ECA11790
If the multi-function display indica-
tes an error code, the vehicle
should be checked as soon as pos-
sible in order to avoid engine
damage.
The self-diagnosis device also
detects problems in the immobilizer
system circuits.If a problem is detected in the immo-
bilizer system circuits, the immobilizer
system indicator light will flash and
the multi-function display will indicate
an error code when the key is turned
to “ON”.
TIP
If the multi-function display indicates
error code 52, this could be caused
by transponder interference. If this

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 interference, which may pre-
vent 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-registe-
ring key and both standard keys
to a Yamaha dealer and have the
standard keys re-registered.
If the multi-function display indicates
any error codes, note the code num-
ber, and then have a Yamaha dealer
check the vehicle.
Clock mode
T
o set the clock:
1. Push the “SELECT” button and
“RESET” button together for at
least two seconds.
2. When the hour digits start flas-
hing, push the “RESET” button to
set the hours.3. Push the “SELECT” button, and
the minute digits will start flas-
hing.
4. Push the “RESET” button to set
the minutes.
5. Push the “SELECT” button and
then release it to start the clock.Ambient temperature display
Pushing the “SELECT” button for at
least two seconds switches the clock
display to the ambient temperature
display. This display shows the
ambient temperature from –10 °C to
50 °C in 1 °C increments. The tempe-
rature displayed may vary from the
ambient temperature. Pushing the
“SELECT” button for at least two
seconds switches the ambient tem-
perature display to the clock display.
TIP
If the ambient temperature falls
below –10 °C, a lower temperatu-
re than –10 °C will not be displa-
yed.
If the ambient temperature
climbs above 50 °C, a higher
temperature than 50 °C will not
be displayed.
The accuracy of the temperature
reading may be affected when
riding slowly (approximately
under 20 km/h (12.5 mi/h)) or
when stopped at traffic signals,
railroad crossings, etc.

Sidestand
1. Sidestand switch
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain
situations. (See page 3-22 for an
explanation of the ignition circuit cut-
off system.)
EWA10240
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand 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. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.
EAU45051
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the
sidestand is up, but neither brake
is applied.
It prevents starting when either
brake is applied, but the sides-
tand 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.
