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.

1. Fuel reserve tripmeter
To reset a tripmeter, select it by pus-
hing the “SELECT” button until “Trip”
or “Trip F” begins flashing (“Trip” or
“Trip F” will only flash for five
seconds). While “Trip” or “Trip F” is
flashing, push the “RESET” button for
at least one second. If you do not
reset the fuel reserve tripmetermanually, it will reset itself automati-
cally and the display will return to the
prior mode after refueling and trave-
ling 5 km (3 mi).
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
towards “E” (Empty) as the fuel level
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
With the key in the “ON” position, the
coolant temperature meter indicates
the temperature of the coolant. The
coolant temperature varies with chan-
ges in the weather and engine load. Ifthe top segment and coolant tempe-
rature warning indicator flash, stop
the vehicle and let the engine cool.

If the engine oil is changed before the
oil change indicator comes on (i.e.
before the periodic oil change interval
has been reached), the indicator must
be reset after the oil change for the
next periodic oil change to be indica-
ted at the correct time. (See page

The electrical circuit of the indicator
can be checked according to the
following procedure.
1. Turn the key to “ON”.
2. Check that the indicator comes
on for a few seconds and then

This indicator flashes every 18000 km
(10500 mi) when the V-belt needs to
be replaced.
The electrical circuit of the indicator
can be checked according to the
following procedure.
1. Turn the key to “ON”.2. Check that the indicator comes

electrical circuit.
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.

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

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-

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.

ABS (for ABS models)
The Yamaha ABS (Anti-lock Brake
System) features a dual electronic
control system, which acts on the
front and rear brakes independently.
The ABS securely controls wheel loc-
kup during emergency braking on
changing road surfaces and under
various weather conditions, thereby
maximizing tire adhesion and perfor-
mance while providing a smooth bra-
king action. The ABS is monitored by
an ECU, which will have recourse to
manual braking if a malfunction
occurs.
EWA10090
The ABS performs best on long
braking distances.
On certain (rough or gravel)
roads, the braking distance
may be longer with than wit-
hout the ABS. Therefore,
always keep a sufficient distan-
ce to the vehicle ahead to
match the riding speed.
TIP
The ABS performs a self-diagno-
sis test for a few seconds each
time the vehicle first starts off
after the key was turned to “ON”.
During this test, a “clicking” noi-
se can be heard from the front of
the vehicle, and if either brake
lever is even slightly applied, a
vibration can be felt at the lever,
but these do not indicate a mal-
function.
When the ABS is activated, the
brakes are operated in the usual
way. A pulsating action may be
felt at the brake levers, but this
does not indicate a malfunction.
This ABS has a test mode which
allows the owner to experience
the pulsating at the brake levers
when the ABS is operating.
However, special tools are requi-
red, so please consult your
Yamaha dealer when performing
this test.WARNING
