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.

er on, or if the light remains on, have a
Yamaha dealer check the vehicle.
NOTICE
ECA26820
If the MIL starts flashing, reduce en-
gine speed to prevent exhaust sys-
tem damage.TIPThe engine is sensitively controlled for
the on-board diagnostic system to de-
tect deterioration and malfunction of
the emission control system. Due to
this specification, the MIL may come
on or flash for vehicle modifications,
lack of maintenance, or excessive or
improper use of the vehicle. To prevent
this, observe these precautions.
Do not attempt to modify the soft-
ware of the engine control unit.
Do not add any electrical acces-
sories that interfere with engine
control.
Do not use aftermarket accesso-
ries or parts such as suspension,
spark plugs, injectors, exhaust
system, etc.
Do not change drivetrain specifi-
cations (chain, sprockets, wheels,
tires, etc.).
