TIP
●For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the
radiator.
●If the engine overheats, see page
6-32 for further instructions.

Speedometer unit
1. “TRIP” button/“RESET” button
2. Multi-function display
3. Speedometer
4. Red zone
The speedometer unit is equipped
with the following:
●a speedometer (which shows the
riding speed)
ECAS0010
NOTICE
Do not operate the scooter in the
speedometer red zone. Red zone:
120 km/h (75 mph) and above
●an odometer (which shows the
total distance traveled)
●a tripmeter (which shows the dis-
tance traveled since it was last
set to zero)
Pushing the “TRIP” button switches
the display between the odometer
mode “ODO” and the tripmeter mode
“TRIP”. To reset the tripmeter, enter
the “TRIP” mode, and then hold down
the “TRIP” button for at least one
second. The tripmeter can be used
together with the fuel gauge to esti-
mate the distance that can be trave-
led with a full tank of fuel. This infor-
mation will enable you to plan future
fuel stops.
Setting the odometer/tripmeter
reading mode
The odometer and tripmeter can be
set to count in either kilometers or
miles according to the following pro-
cedure.
1. Turn the key to “ ” while pres-
sing the reset button.
2. Release the reset button when
the display comes on.
3. The current mode appears in the
display: “CONT” (continental) for
the kilometer mode and “EnGL”
(English) for the mile mode.

3. Minimum level mark
3. If the coolant is at or below the
minimum level mark, remove
panel A (See page 6-7), remove
the reservoir cap, add coolant to
the maximum level mark, and
then install the reservoir cap and
the panel. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the
radiator cap when the engine is
hot.
[EWA15161]. NOTICE: If coolant
is not available, use distilled
water or soft tap water instead.
Do not use hard water or salt
water since it is harmful to theengine. If water has been used
instead of coolant, replace it
with coolant as soon as possi-
ble, otherwise the cooling sys-
tem will not be protected
against frost and corrosion. If
water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possi-
ble, otherwise the effective-
ness of the coolant will be
reduced.

Changing the coolant
The coolant must be changed at the
intervals specified in the periodic
maintenance and lubrication chart.
Have a Yamaha dealer change the
coolant. WARNING! Never attempt
to remove the radiator cap when
the engine is hot.

Replacing the fuses
1. Main fuse
2. Radiator fan fuse
The main fuse box and the fuse box,
which contains the fuses for the indi-
vidual circuits, are located under
panel B. (See page 6-7).
If a fuse is blown, replace it as
follows.
1. Turn the key to “ ” and turn off
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher ampera-
ge rating than recommended
to avoid causing extensivedamage to the electrical sys-
tem and possibly a fire.
[EWA15131]
3. Turn the key to “ ” and turn on
the electrical circuit in question to
check if the device operates.
4. If the fuse immediately blows
again, have a Yamaha dealer
check the electrical system.

Replacing a headlight bulb
This model is equipped with quartz
bulb headlights. If a headlight bulb
burns out, replace it as follows.
ECA10650
NOTICE
Take care not to damage the follo-
wing parts:
●Headlight bulb
Do not touch the glass part of
the headlight bulb to keep it
free from oil, otherwise the
transparency of the glass, the
luminosity of the bulb, and the
bulb life will be adversely affec-
ted. Thoroughly clean off any
dirt and fingerprints on the
headlight bulb using a cloth
moistened with alcohol or thin-
ner.
●Headlight lens
Do not affix any type of tinted
film or stickers to the headlight
lens.
Do not use a headlight bulb of
a wattage higher than speci-
fied.
Specified fuses:
Main fuse:

WARNING
●Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
●After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the his-
sing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIP
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.
Wait until the
engine has cooled.Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.
The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.
Add coolant. (See TIP.)
Start the engine. If the engine overheats again, have a
Yamaha dealer check and repair the cooling system.
There is
leakage.
There is
no leakage.
