SAFETY INFORMATION

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.

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 ambient temperature display

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
“TRIP” in the following order:
ODO
→
TRIP (top)
→
TRIP (bottom)

fuel meter and fuel level warning sym-
bol will start flashing, and the display
will automatically change to the fuel re-
serve tripmeter mode “TRIP F” and
start counting the distance traveled
from that point. In that case, pushing
the “SELECT” button switches the dis-
play between the various tripmeter and
odometer modes in the following order:
TRIP F
→
TRIP (top)
→

To reset a tripmeter, select it by push-
ing the “SELECT” button, and then
push the “RESET” button for at least
one second. If you do not reset the fuel
reserve tripmeter manually, it will resetitself automatically and the display will
return 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 6-37.)
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 en-
gine oil should be changed.
After changing the engine oil, reset the
oil change indicator. (See page 6-12.)
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

ver first before moving the rear
brake lock lever to the left.
WARNING

EWA12361
Never move the rear brake lock lever
to the left while the vehicle is mov-
ing, otherwise loss of control or an
accident may result. Make sure that
the vehicle is stopped before mov-
ing the rear brake lock lever to the
left.

CAUTION:

ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand
or premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.
EAU13440
Catalytic converter
This vehicle is equipped with a catalytic
converter in the muffler.
WARNING

EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-
ing any maintenance work.
CAUTION:

ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.

Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.

Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.

Do not allow the engine to idle
too long.
