Coolant
The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU52024To check the coolant level 1. Place the vehicle on the center- stand.
TIP
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
Make sure that the vehicle is posi-
tioned 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.
TIP
The coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below the minimum level mark, remove the
left floorboard mat by pulling it up. 4. Remove the coolant reservoir cov-
er by removing the screw.
5. Remove the coolant reservoir cap, add coolant to the maximum level
mark, and then install the reservoir
cap. WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the radiator
cap when the engine is
hot.
[EWA15162] 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 the engine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and

Troubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting chart
represents a quick and easy procedure
for checking these vital systems your-
self. However, should your scooter re-
quire any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the scooter prop-
erly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look like
Yamaha parts, but they are often inferi-
or, have a shorter service life and can
lead to expensive repair bills.
WARNING
EWA15142
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from water
heaters or furnaces. Gasoline or
gasoline vapors can ignite or ex-
plode, causing severe injury or
property damage.
EAU77992Smart key system troubleshooting
Please check the following items when
the smart key system does not work.
Is the smart key turned on? (See
page 3-5.)
Is the smart key battery dis-
charged? (See page 3-6.)
Is the smart key battery installed correctly? (See page 3-6.)
Is the smart key being used in a lo-
cation with strong radio waves or
other electromagnetic noise? (See
page 3-1.)
Are you using the smart key that is
registered to the vehicle?
Is the vehicle battery discharged?
When the vehicle battery is dis-
charged, the smart key system will
not operate. Please have the vehi-
cle battery charged or replaced.
(See page 8-27.)
If the smart key system does not work
after checking the above items, have a
Yamaha dealer check the smart key
system.
TIP
See Emergency mode on page 8-36 for
information on starting the engine with-
out the smart key.

Emergency mode
When the smart key is lost, damaged,
or its battery has discharged, the vehi-
cle can still be turned on and the engine
started. You will need a mechanical key
and the smart key system identification
number. To operate the vehicle in
emergency mode, carry out the follow-
ing steps.
TIP
Emergency mode operation will be
cancelled if the respective steps are not
carried out within the time set for each
operation or if the “OFF/LOCK” switch
is pushed. 1. Stop the vehicle in a safe place.
2. Unlock the seat by inserting the mechanical key into the lock locat-
ed right side of body and turn it
counter clockwise.
3. Open the seat and check that the trunk light comes on.
4. Push the “ON/ ” switch once.
5. Without completely shutting the seat, raise and lower it three times
within 10 seconds.
TIP
Use the rear storage compartment light
as a guide when raising and lowering
the seat. The smart key system indicator
light on the speedometer will come
on for three seconds to indicate
the transition to emergency mode.
6. After the smart key system indica- tor light goes off, use the “ / ”
switch to enter the identification
number.
7. Inputting the identification number is done by counting the number of
flashes of the smart key system in-
dicator light.
For example, if the identification
number is 123456:
Push and hold the “ / ” switch.

The smart key system indicator
light will start to flash.
