The corresponding indicator light flash-
es when the turn signal switch is
pushed to the left or right.
EAU11060
Neutral indicator light “”
This indicator light comes on when the
transmission is in the neutral position.

High beam indicator light “”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU11254
Oil level warning light “”
This warning light comes on if the en-
gine oil level is low.
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.
TIP

Even if the oil level is sufficient, the
warning light may flicker when
riding on a slope or during sudden
acceleration or deceleration, but
this is not a malfunction.


This model is also equipped with a
self-diagnosis device for the oil
level detection circuit. If a problem
is detected in the oil level detection
circuit, the following cycle will be
repeated until the malfunction is
corrected: The oil level warning
light will flash ten times, then go off
for 2.5 seconds. If this occurs,
have a Yamaha dealer check the
vehicle.
EAU49421
Coolant temperature warning
light “”
This warning light comes on if the en-
gine overheats. If this occurs, stop the
engine immediately and allow the en-
gine to cool.
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.
NOTICE
ECA10021
Do not continue to operate the en-
gine if it is overheating.TIP

For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the ra-
diator.


If the engine overheats, see page

into the air filter case.
This display shows the air intake tem-

When the air temperature is below
–9 °C, “Lo” will be displayed.

Even if the air intake temperature
is set to be displayed, the coolant

OPERATION AND IMPORTANT RIDING POINTS

EAU16810
Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Shift up swiftly, and avoid high en-
gine speeds during acceleration.


Do not rev the engine while shifting
down, and 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 traffic
lights or at railroad crossings).
EAU16841
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 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.
EAU17123
0–1000 km (0– 600 mi)
Avoid prolonged operation above 3900
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil and
final gear oil must be changed, and
the oil filter cartridge or element re-
placed.
[ECA10332]
1000 –1600 km (600 –1000 mi)
Avoid prolonged operation above 4700
r/min.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.NOTICE
ECA10310


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.

6Engine overheating
WARNING
EWAT1040


Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.


Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the de-
tent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the cap
while turning it counterclockwise, and then remove the cap.
TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See TIP.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is

There is
no leakage.
