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 charts
represent quick and easy procedures
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.
Smart 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

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 7-28.)
If the smart key system does not work
after checking the above-mentioned
items, have a Yamaha dealer check the
smart key system.
TIP
Refer to emergency mode on page
7-38 on how to start the engine without
using 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. (See page 3-3.) To operate
the vehicle in emergency mode, carry
out the following 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 inside
the front storage compartment and
turn it 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 “SEAT
OPEN/ ” switch to enter the
identification number. Refer to the
following procedure on how to in-
put 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 “SEAT
OPEN/ ” switch.

ber have been set. The smart key
system indicator light will flash for
10 seconds if the correct identifica-
tion number was entered.
TIP
Emergency mode will be terminated
when either one of the following situa-
tions apply. In this case, start over
again from step 4.
When there are no “SEAT
OPEN/ ” switch operations for 10 seconds during the identifica-
tion number input process.
When the smart key system indi-
cator light is allowed to flash 10 or
more times.
8. Press the “ON/ ” switch while the smart key system indicator light is
flashing to turn on the power to the
vehicle. The engine can now be

correctly entered, the smart key
system indicator light will flash rap-
idly for 3 seconds and emergency
mode is terminated. In this case,
start over again from step 4.

on the vehicle in emergency mode,
turn the vehicle power off, wait 30
seconds, and then turn the handle-
bar to the left and press the
