SAFETY INFORMATION
1-2
1
Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
The posture of the operator and
passenger is important for proper
control.
The operator should keep both
hands on the handlebar and
both feet on the footboard during
operation to maintain control of
the scooter.
The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger footrests.
Never carry a passenger unless
he or she can firmly place both
feet on the passenger footrests.
Never ride under the influence of
alcohol or other drugs.
This scooter is designed for
on-road use only. It is not suitable
for off-road use.
Protective apparel
The majority of fatalities from scooter
accidents are the result of head inju-ries. The use of a safety helmet is the
single most critical factor in the preven-
tion or reduction of head injuries.
Always wear an approved helmet.
Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision which could delay seeing
a hazard.
The use of a jacket, substantial
shoes, trousers, gloves, etc., is ef-
fective in preventing or reducing
abrasions or lacerations.
Never wear loose-fitting clothes,
otherwise they could catch on the
control levers or wheels and cause
injury or an accident.
Never touch the engine or exhaust
system during or after operation.
They become very hot and can
cause burns. Always wear protec-
tive clothing that covers your legs,
ankles, and feet.
Passengers should also observe
the above precautions.
Modifications
Modifications made to this scooter notapproved by Yamaha, or the removal of
original equipment, may render the
scooter unsafe for use and may cause
severe personal injury. Modifications
may also make your scooter illegal to
use.
Loading and accessories
Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution of
the scooter is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or accesso-
ries to your scooter. Use extra care
when riding a scooter that has added
cargo or accessories. Here are some
general guidelines to follow if loading
cargo or adding accessories to your
scooter:
Loading
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Maximum load:
YP400 189 kg (417 lb)
YP400A 185 kg (408 lb)

Engine trouble warning light “”
This warning light comes on when an
electrical circuit monitoring the engine
is defective. When this occurs, have a
Yamaha dealer check the self-diagno-
sis system.
The electrical circuit of the warning light
can be checked by turning the key to
“ON”. If the warning light does not come
on for a few seconds, then go off, have
a Yamaha dealer check the electrical
circuit.
EAU11551
ABS warning light “” (for ABS
models)
CAUTION:
ECA10830
If the ABS warning light comes on or
flashes while riding, the ABS may be
defective. If this occurs, have a
Yamaha dealer check the electrical
circuit.
See page 3-12 for an explanation of the
ABS.The electrical circuit of the warning light
can be checked by setting the engine
stop switch to “” and turning the key
to “ON”. The warning light should come
on for a few seconds, and then go off. If
the warning light does not come on or
remains on, have a Yamaha dealer
check the electrical circuit.
WARNING
EWA11350
When the ABS warning light comes
on or flashes while riding, the brake
system reverts to conventional brak-
ing. Therefore, be careful not to
cause the wheel to lock during emer-
gency braking.
NOTE:
The ABS warning light may come on
while pushing the start switch and while
accelerating the engine with the scoot-
er on its centerstand, but this does not
indicate a malfunction.
EAU38620
Immobilizer system indicator light
The electrical circuit of the indicator
light can be checked by turning the keyto “ON”.
If the indicator light does not come on
for a few seconds, then go off, have a
Yamaha dealer check the electrical cir-
cuit.
When the key is turned to “OFF” and 30
seconds have passed, the indicator
light will start flashing indicating the im-
mobilizer system is enabled. After 24
hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.
This model is also equipped with a
self-diagnosis device for the immobiliz-
er system. (See page 3-5 for an expla-
nation of the self-diagnosis device.)

WARNING
EWA12361

to the left while the vehicle is mov-
ing, otherwise loss of control or an
accident may result. Make sure that
the vehicle is stopped before mov-
ing the rear brake lock lever to the
left.
EAU12991
ABS (for ABS models)
The Yamaha ABS (Anti-lock Brake
System) features a dual electronic con-
trol system, which acts on the front and
rear brakes independently. The ABS
securely controls wheel lockup during
emergency braking on changing road
surfaces and under various weather
conditions, thereby maximizing tire ad-
hesion and performance while provid-
ing a smooth braking action. The ABS
is monitored by an ECU (Electronic
Control Unit), which will have recourse
to manual braking if a malfunction oc-
curs.
WARNING
EWA10090
The ABS performs best on long
braking distances.
On certain (rough or gravel)
roads, the braking distance may
be longer with than without the
ABS. Therefore, always keep a
sufficient distance to the vehi-
cle ahead to match the riding
speed.
NOTE:
When the ABS is activated, the
brakes are operated in the usual
way. A pulsating action may be felt
at the brake levers, but this does
not indicate a malfunction.
This ABS has a test mode which
allows the owner to experience the
pulsating at the brake levers when
the ABS is operating. However,
special tools are required, so
please consult your Yamaha deal-
er when performing this test.
