Fuel gauge
1. Fuel gauge
2. Fuel level warning light “ ”
The fuel gauge indicates the amount
of fuel in the fuel tank. The needle
moves towards “E” (Empty) as the
fuel level decreases. When the remai-
ning fuel in the tank reaches approxi-
mately 2 L (0.53 US gal) (0.44
Imp.gal), the fuel level warning light
will come on and the multi-function
display will automatically change to
the “Trip/fuel” mode. (See page 3-6.)
If this occurs, refuel as soon as possi-
ble.
NOTE:
Do not allow the fuel tank to empty
itself completely.EAU12171
Coolant temperature gauge
1. Red zone
2. Coolant temperature gauge
With the key in the “ON” position, the
coolant temperature gauge indicates
the temperature of the coolant. The
coolant temperature varies with chan-
ges in the weather and engine load. If
the needle reaches or enters the red
zone, stop the vehicle and let the
engine cool. (See page 6-34.)

CAUTION:
Do not operate the engine if it is
overheated.

Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUS1273
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
NOTE:
●The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
●Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level through
the check window.
NOTE:
The coolant should be between the
minimum and maximum level marks.
1. Maximum level mark
2. Minimum level mark
3. Coolant level window
3. If the coolant is at or below the
minimum level mark, remove the
right floorboard mat by pulling it
up.
4. Open the reservoir cap, and then
add coolant to the maximum
level mark.
1. Coolant reservoir cap
ECA10471
CAUTION:
●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 the engine.
●If water has been used instead
of coolant, replace it with coo-
lant as soon as possible, other-
wise the cooling system 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.

WARNING
Never attempt to remove the radia-
tor cap when the engine is hot.

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

Air filter and V-belt case air
filter elements
The air filter element should be repla-
ced and the V-belt case air filter ele-
ment should be cleaned at the inter-
vals specified in the periodic
maintenance and lubrication chart.
Service the air filter elements more
frequently if you are riding in unu-
sually wet or dusty areas.
Replacing the air filter element
1. Place the scooter on the centers-
tand.
2. Remove the air filter case cover
by removing the screws.

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.
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 NOTE.)
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.
NOTE:
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.
