PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpect-
edly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leak-
age or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thor-
ough visual inspection, to check the following points before each ride.

case for oil leakage. If oil is leak-
ing, check for the cause.

CoolantCoolantThe coolant reservoir is located
under the battery cover. (See page
6-34 for battery cover removal and
installation procedures.)
To check the coolant level
1. Place the scooter on a level sur-
face and hold it in an upright
position.NOTE:
8The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
8Make sure that the scooter 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 in the
coolant reservoir.NOTE:
The coolant should be between the
minimum and maximum level marks.

minimum level mark, remove the
reservoir cap, add coolant to the
maximum level mark, and then
install the reservoir cap.
4. Install the battery cover.

cC8If 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.
8If water has been used instead
of coolant, replace it with
coolant as soon as possible,
otherwise the engine may not
be sufficiently cooled and the
cooling system will not be pro-
tected against frost and corro-
sion.
8If 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.
NOTE:
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radiator. If
the engine overheats, see page 6-44
for further instructions.

Removing the battery coverBattery cover removalThe battery cover needs to be
removed to access the battery, the
fuse box and the coolant reservoir
cap.
EAU01271
BatteryBatteryThis scooter is equipped with a
sealed-type (MF) battery, which does
not require any maintenance. There
is no need to check the electrolyte or
to add distilled water.
To charge the battery
Have a Yamaha dealer charge the
battery as soon as possible if it
seems to have discharged. Keep in
mind that the battery tends to dis-
charge more quickly if the scooter is
equipped with optional electrical
accessories.

6 Engine overheating
EW000070
w8Do 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.
8After 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
hissing 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
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.
