WARNING
EWAT1041
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.
Place a thick rag, like a towel, over the radiator cap, and then slowly ro-
tate the cap counterclockwise to the detent to allow any residual pres-
sure to escape. When the hissing 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 c
an 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.Add coolant.
(See TIP.)
The coolant level is
OK.
There is no leakage.
There is leakage.
The coolant level is
low.
Check the cooling
system for leakage.
Have a Yamaha
dealer check and
repair the cooling
system.
Start the engine. If the engine overheats again,
have a Yamaha dealer check and repair the cooling
system.

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.

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
started.
TIP
If the identification number is not
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.
To lock the handlebar after turning
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
“OFF/LOCK” switch.

Scooter care and storage
EAU37834
Matte color caution
NOTICE
ECA15193
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use be-
fore cleaning the vehicle. Using a
brush, harsh chemical products or
cleaning compounds when cleaning
these parts will scratch or damage
their surface. Wax also should not
be applied to any matte colored fin-
ished parts.
EAU26106
Care
While the open design of a scooter re-
veals the attractiveness of the technol-
ogy, it also makes it more vulnerable.
Rust and corrosion can develop even if
high-quality components are used. A
rusty exhaust pipe may go unnoticed
on a car, however, it detracts from the
overall appearance of a scooter. Fre-
quent and proper care does not only
comply with the terms of the warranty,
but it will also keep your scooter looking
good, extend its life and optimize its
performance.
Before cleaning 1. Cover the muffler outlet with a plastic bag after the engine has
cooled down.
2. Make sure that all caps and covers as well as all electrical couplers
and connectors, including the
spark plug cap, are tightly in-
stalled.
3. Remove extremely stubborn dirt, like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets and wheel
axles. Always rinse the dirt and de-
greaser off with water.
Cleaning
NOTICE
ECA10784
Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the af-
fected area any longer than in-

Storage
Short-term
Always store your scooter in a cool, dry
place and, if necessary, protect it
against dust with a porous cover. Be
sure the engine and the exhaust sys-
tem are cool before covering the scoot-
er.
NOTICE
ECA10821
Storing the scooter in a poorly
ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to
seep in and cause rust.
To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
Long-term
Before storing your scooter for several
months: 1. Follow all the instructions in the “Care” section of this chapter.
2. Fill up the fuel tank and add fuel stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
3. Perform the following steps to pro- tect the cylinders, piston rings, etc.
from corrosion.
a. Remove the spark plug caps and the spark plugs.
b. Pour a teaspoonful of engine oil into the spark plug bores.
c. Install the spark plug caps onto the spark plugs, and then place
the spark plugs on the cylinder head so that the electrodes are
grounded. (This will limit spark-
ing during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder walls with oil.)
e. Remove the spark plug caps from the spark plugs, and then
install the spark plugs and the
spark plug caps. WARNING!
To prevent damage or injury
from sparking, make sure to
ground the spark plug elec-
trodes while turning the en-
gine over.
[EWA10952]
4. Lubricate all control cables and the pivoting points of all levers and
pedals as well as of the sides-
tand/centerstand.
5. Check and, if necessary, correct the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
6. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.
7. Remove the battery and fully charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex-
cessively cold or warm place [less
than 0 C (30 F) or more than 30
 C (90 F)]. For more information
on storing the battery, see page
7-28.
TIP
Make any necessary repairs before
