Safety information
EAU1026B
Be a Responsible Owner
As the vehicle’s owner, you are re-
sponsible for the safe and proper oper-
ation of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements be-
fore riding this scooter.
He or she should:  Obtain thorough instructions from
a competent source on all aspects
of scooter operation.
 Observe the warnings and mainte-
nance requirements in this Own-
er’s Manual.
 Obtain qualified training in safe
and proper riding techniques.
 Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made neces-
sary by mechanical conditions. 
Never operate a scooter without
proper training or instruction. Take
a training course. Beginners
should receive training from a cer-
tified instructor. Contact an autho-
rized scooter dealer to find out
about the training courses nearest
you.
Safe Ri din g
Perform the pre-operation checks
each time you use the vehicle to make
sure it is in safe operating condition.
Failure to inspect or maintain the vehi-
cle properly increases the possibility of
an accident or equipment damage.
See page 5-1 for a list of pre-operation
checks.  This scooter is designed to carry
the operator and a passenger.
 The failure of motorists to detect
and recognize scooters in traffic is
the predominating cause of auto-
mobile/scooter accidents. Many
accidents have been caused by
an automobile driver who did not
see the scooter. Making yourself conspicuous appears to be very
effective in reducing the chance of
this type of accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you are approaching and passing
through intersections, since in-
tersections are the most likely
places for scooter accidents to
occur.
• Ride where other motorists can see you. Avoid riding in another
motorist’s blind spot.
• Never maintain a scooter with- out proper knowledge. Contact
an authorized scooter dealer to
inform you on basic scooter
maintenance. Certain mainte-
nance can only be carried out
by certified staff.UBBAE0E0.book Page 1 Thursday, September 24, 2020 3:19 PM

Malfunction in dicator li ght
(MIL) “ ”
This light comes on or flashes if a prob-
lem is detected in the engine or other
vehicle control system. If this occurs,
have a Yamaha dealer check the on-
board diagnostic system. The electri-
cal circuit of the warning light can be
checked by vehicle power on. The light
should come on for a few seconds,
and then go off. If the light does not
come on initially when the vehicle pow-
er on, or if the light remains on, have a
Yamaha dealer check the vehicle.NOTICE
ECA26820
If the MIL starts flashin g, re duce en-
g ine spee d to prevent exhaust sys-
tem damag e.
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.).
 Do not remove or alter the O2 sen-
sor, air induction system, or ex-
haust parts (catalysts or EXUP,
etc.).
 Maintain proper V-belt and drive
belt (if equipped).

Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replace-
ment, or repair of the emission control
devices and systems may be per-
formed by any repair establishment or
individual that is certified (if applicable).
Yamaha dealers are trained and equipped to perform these particular
services.
