High beam indicator light “ ”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU11354
Fuel level warning light “ ”
This warning light comes on when the
fuel level drops below approximately
2.5 L (0.66 US gal, 0.55 Imp.gal). When
this occurs, refuel as soon as possible.
The electrical circuit of the warning
light can be checked by 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
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.
EAU43024
Engine trouble warning light “ ”
This warning light comes on if an elec-
trical circuit monitoring the engine is
not working correctly. If this occurs,
have a Yamaha dealer check the self-
diagnosis system.The electrical circuit of the warning
light can be checked by 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
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.
TIPThis warning light will come on when

switch is pushed, but this does not in-
dicate a malfunction.
EAUM3381
ABS warning light “ ” (for ABS
models)
In normal operation, the ABS warning
light comes on when the key is turned
to “ON”, and goes off after traveling at
a speed of 10 km/h (6 mi/h) or higher.
If the ABS warning light:
does not come on when the key is
turned to “ON”
comes on or flashes while ridingdoes not go off after traveling at a
speed of 10 km/h (6 mi/h) or high-
er
The ABS may not work correctly. If any
of the above occurs, have a Yamaha
dealer check the system as soon as
possible. (See page 3-16 for an expla-
nation of the ABS.)
WARNING
EWA16041
If the ABS warning light does not go
off after traveling at a speed of 10
km/h (6 mi/h) or higher, or if the
warning light comes on or flashes
while riding, the brake system re-
verts to conventional braking. If ei-
ther of the above occurs, or if the
warning light does not come on at
all, use extra caution to avoid possi-
ble wheel lock during emergency
braking. Have a Yamaha dealer
check the brake system and electri-
cal circuits as soon as possible.

TIPThe ABS warning light may come on
while accelerating the engine with the
scooter on its centerstand, but this
does not indicate a malfunction.

Immobilizer system indicator
light “ ”
The electrical circuit of the indicator
light can be checked by turning the key
to “ON”. The indicator light should
come on for a few seconds, and then
go off.
If the indicator light does not come on
initially when the key is turned to “ON”,
or if the indicator light remains on, have
a Yamaha dealer check the electrical
circuit.
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.The self-diagnosis device also detects
problems in the immobilizer system
circuits. (See page 3-12 for an expla-
nation of the self-diagnosis device.)

Ignition circuit cut-off systemThe ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the side-
stand is up, but neither brake is
applied.
It prevents starting when either
brake is applied, but the sidestand
is still down.
It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system accord-
ing to the following procedure.

5dicator light remains on, see page
3-3 for the corresponding warning
and indicator light circuit check.
For ABS models:The ABS warning light should
come on when the main switch is
turned to “ON” and then go off af-
ter traveling at a speed of 10 km/h
(6 mi/h) or higher.
NOTICE
ECA17682
If the ABS warning light does not
come on and then go off as ex-
plained above, see page 3-3 for the
warning light circuit check.2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the
front or rear brake. If the engine does not start, re-
lease the start switch, wait a few
seconds, and then try again. Each
starting attempt should be as
short as possible to preserve the
battery. Do not crank the engine
more than 10 seconds on any one
attempt.
NOTICE
ECA11043
For maximum engine life, never ac-
celerate hard when the engine is
cold!

EAU16821
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
Avoid high engine speeds during
acceleration.
Avoid high engine speeds with no
load on the engine.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16831
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAUS1841
0–500 km (0–300 mi)
Avoid prolonged operation above 5000
r/min.
500–1000 km (300–600 mi)
Avoid prolonged operation above 7500
r/min. NOTICE: After 1000 km (600
mi) of operation, be sure to replace
the engine oil, final transmission oil
and the oil filter element.
[ECA12932]
1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.NOTICE
ECA10311
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.

6To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light
tan (the ideal color when the vehi-
cle is ridden normally).
TIPIf the spark plug shows a distinctly dif-
ferent color, the engine could be oper-
ating improperly. Do not attempt to
diagnose such problems yourself. In-
stead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.
3. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.To install the spark plug
1. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
2. Install the spark plug with the
spark plug wrench, and then tight-
en it to the specified torque.
TIPIf a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4…
1/2 turn past finger tight. However, the
spark plug should be tightened to the
specified torque as soon as possible.3. Install the spark plug cap.
4. Place the rear storage compart-
ment in the original position and
install the bolts.
5. Close the seat.
