sories exceed the capacity of the
scooter’s electrical system an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.
Gasoline and exhaust gas

GASOLINE IS HIGHLY FLAMMA-
BLE:

Always turn the engine off when
refueling.

Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.

Never refuel while smoking or in
the vicinity of an open flame.

Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within a
short time. Always operate your
scooter in an area that has ade-
quate ventilation.

Always turn the engine off before
leaving the scooter unattended
and remove the key from the mainswitch. When parking the scooter,
note the following:

The engine and exhaust system
may be hot, therefore, park the
scooter in a place where pedes-
trians or children are not likely to
touch these hot areas.

Do not park the scooter on a
slope or soft ground, otherwise it
may fall over.

Do not park the scooter near a
flammable source (e.g., a kero-
sene heater, or near an open
flame), otherwise it could catch
fire.

If you should swallow any gaso-
line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediate-
ly. If any gasoline spills on your
skin or clothing, immediately wash
the affected area with soap and
water and change your clothes.
EAU10370
Further safe-riding points

Be 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
stopping 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 be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.

The brake pads could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.

Immobilizer system
This vehicle is equipped with an immo-
bilizer system to help prevent theft by
re-registering codes in the standard
keys. This system consists of the fol-
lowing.

a code re-registering key (with a
red bow)

two standard keys (with a black
bow) that can be re-registered with
new codes

a transponder (which is installed in
the code re-registering key)

an immobilizer unit

an ECU

an immobilizer system indicator
light (See page 3-3.)
The key with the red bow is used to reg-
ister codes in each standard key. Since
re-registering is a difficult process, take
the vehicle along with all three keys to
a Yamaha dealer to have them re-reg-
istered. Do not use the key with the red
bow for driving. It should only be used
for re-registering the standard keys. Al-
ways use a standard key for driving.
CAUTION:

ECA11820

DO NOT LOSE THE CODE
RE-REGISTERING KEY! CON-
TACT YOUR DEALER IMMEDI-
ATELY IF IT IS LOST! If the code
re-registering key is lost, regis-
tering new codes in the stan-
dard keys is impossible. The
standard keys can still be used
to start the vehicle, however if
code re-registering is required
(i.e., if a new standard key is
made or all keys are lost) the en-
tire immobilizer system must be
replaced. Therefore, it is highlyrecommended to use either
standard key and keep the code
re-registering key in a safe
place.

Do not submerse any key in wa-
ter.

Do not expose any key to exces-
sively high temperatures.

Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).

Do not place heavy items on any
key.

Do not grind any key or alter its
shape.

Do not disassemble the plastic
part of any key.

Do not put two keys of any im-
mobilizer system on the same
key ring.

Keep the standard keys as well
as keys of other immobilizer
systems away from this vehi-
cle’s code re-registering key.

Keep other immobilizer system

NOTE:

Be sure to use the standard key (black
bow) for regular use of the vehicle. To
minimize the risk of losing the code
re-registering key (red bow), keep it in a
safe place and only use it for code
re-registering.

Multi-function display
WARNING

EWA12311
Be sure to stop the vehicle before
making any setting changes to the
multi-function display.
The multi-function display is equipped
with the following:

a fuel meter

a coolant temperature meter

an odometer (which shows the to-
tal distance traveled)

two tripmeters (which show the
distance traveled since they were
last set to zero)

a fuel reserve tripmeter (which
shows the distance traveled since
the bottom segment of the fuel
meter and fuel level warning sym-bol started flashing)

a self-diagnosis device

a clock

an oil change indicator

a V-belt replacement indicator
NOTE:


Be sure to turn the key to “ON” be-
fore using the “SELECT” and “RE-
SET” buttons.

When the key is turned to “ON”, all
of the display segments of the
multi-function display will appear
one after the other and then disap-
pear, in order to test the electrical
circuit.
Odometer and tripmeter modes
Pushing the “SELECT” button switches
the display between the odometer
mode “ODO” and the tripmeter modes

push the “RESET” button for at least
one second. If you do not reset the fuel
reserve tripmeter manually, it will reset
itself automatically and the display willreturn to the prior mode after refueling
and traveling 5 km (3 mi).
Fuel meter
With the key in the “ON” position, the
fuel meter indicates the amount of fuel
in the fuel tank. The display segments
of the fuel meter disappear towards “E”
(Empty) as the fuel level decreases.
When the fuel level reaches the bottom
segment is left near “E”, the fuel level
warning symbol and the bottom seg-
ment will flash. Refuel as soon as pos-
sible.
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 chang-
es in the weather and engine load. If
the top segment and coolant tempera-
ture symbol flash, stop the vehicle and
let the engine cool. (See page 6-32.)
CAUTION:

ECA10020
Do not operate the engine if it is
overheated.
Oil change indicator “OIL”
This indicator flashes at the initial
1000 km (600 mi), then at 5000 km
(3000 mi) and every 5000 km (3000 mi)
thereafter to indicate that the engine oil
should be changed.
After changing the engine oil, reset the
oil change indicator. (See page 6-10.)
If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the periodic oil change interval has
been reached), the indicator must be
reset after the oil change for the next
