munication equipment such as
radios or mobile phones in
close proximity of the smart key
The smart key is in contact with
or covered by a metallic object
Other vehicles equipped with a
smart key system are nearby
In such situations, move the smart

abled). In this situation, simply push
the main switch knob to turn the smart
key system back on.

If the smart key is turned off, the vehi-
cle will not recognize the smart key
even if it is within operating range. If the
smart key battery is discharged, thesmart key system may not work or its
operating range may become very
short.
TIPDo not place the smart key in a
storage compartment.

tery. Therefore it is recommended that
you carry one mechanical key together
with the smart key.
If the smart key and the smart key sys-
tem identification number are both lost
or damaged, the entire smart key sys-
tem will need to be replaced. To pre-
vent this, it is recommended that youwrite down the identification num-
ber in case the identification number

EAU76825
Stop and Start SystemThe Stop and Start System stops the
engine automatically when the vehicle
is stopped in order to prevent noise,
control exhaust emissions, and reduce
fuel consumption.
When the rider turns the throttle grip
slightly, the engine restarts automati-
cally and the vehicle starts off.NOTICE
ECA23961
When parking the vehicle or leaving
the vehicle unattended, be sure to
turn the main switch off. If the Stop
and Start System is left turned on,
the battery could become dis-charged and it may not be possible
to restart the engine due to insuffi-
cient battery voltage.
TIPAlthough the engine normally
stops at the same time as the ve-
hicle, there may be a delay when
operating the vehicle under 10
km/h, such as in heavy traffic.
If you think the battery voltage is
low because the engine cannot be
started using the starter switch or
for some other reason, do not turn
on the Stop and Start System.
Have a Yamaha dealer check the
battery at the intervals specified in
the periodic maintenance chart.
