When the ABS warning light
comes on or flashes while riding,
the brake system reverts to con-
ventional braking. Therefore, be
careful not to cause the wheel to
lock during emergency braking.
NOTE:
The ABS warning light may come on
while pushing the start switch and
while accelerating the engine with the
scooter on its centerstand, but this
does not indicate a malfunction.

Oil change indicator light “7”Oil change indicator lightThis indicator light comes on at the
initial 1,000 km and every 3,000 km
thereafter to indicate that the engine
oil should be changed.
If the engine oil is changed before the
oil change indicator comes on (i.e.
before the periodic oil change interval
has been reached), the indicator light
must be reset after the oil change for
the next periodic oil change to be
indicated at the correct time. (See
page 6-17 for the resetting proce-
dure.)
The electrical circuit of the indicator
light can be checked according to the
following procedure.
1. Set the engine stop switch to “#”
and turn the key to “ON”.
2. Check that the indicator comes
on for a few seconds and then
goes off.
3. If the indicator light does not
come on, have a Yamaha dealer
check the electrical circuit.
NOTE:
The oil change indicator light may
flash when the engine is revved with
the scooter on the centerstand, but
this does not indicate a malfunction.

ABSABSThe Yamaha ABS (Anti-lock Brake
System) features a dual electronic
control 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 adhesion and perfor-
mance while providing a smooth
braking action. The ABS is monitored
by an ECU (Electronic Control Unit),
which will have recourse to manual
braking if a malfunction occurs.

The ABS performs best on
long braking distances.
8 8
On certain (rough or gravel)
roads, the braking distance
may be longer with than with-
out the ABS. Therefore, always
keep a sufficient distance to
the vehicle ahead to match the
riding speed.
NOTE:
8When 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.
8This 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 dealer when performing
this test.

Final transmission oilFinal transmission oilThe final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a
Yamaha dealer check and repair the
scooter. In addition, the final trans-
mission oil must be changed as fol-
lows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine, warm it up by
riding the scooter for several
minutes, and then stop the
engine.
2. Place the scooter on the center-
stand.
3. Place an oil pan under the final
transmission case to collect the
used oil.

Cast wheelsWheelsTo maximize the performance, dura-
bility, and safe operation of your
scooter, note the following points
regarding the specified wheels.
8The wheel rims should be
checked for cracks, bends or
warpage before each ride. If any
damage is found, have a
Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A
deformed or cracked wheel must
be replaced.
8The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.
EAU00683

8 8
Have a Yamaha dealer replace
excessively worn tires.
Besides being illegal, operat-
ing the scooter with exces-
sively worn tires decreases
riding stability and can lead to
loss of control.
8 8
The replacement of all wheel
and brake related parts,
including the tires, should be
left to a Yamaha dealer, who
has the necessary profession-
al knowledge and experience.
