Neutral indicator light “ N”
This indicator light comes on when the
transmission is in the neutral position.
The electrical circuit of the neutral indi-
cator light can be checked by turning
the key to "ON". If the indicator light
does not come on for a few seconds,
then go off, have a Yamaha dealer
check the electrical circuit.
EAUB1530
High beam indicator light “1”
This indicator light comes on when the
high beam of the headlight is switched
on. The electrical circuit of the high
beam indicator light can be checked
by turning the key to "ON". If the indi-
cator light does not come on for a few
seconds, then go off, have a Yamaha
dealer check the electrical circuit.
EAU11444
Coolant temperature warning
light “u”
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 turn-
ing 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 deal-
er check the electrical circuit.
ECA10021
NOTICE
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
7-41 for further instructions.
EAU11534
Engine trouble warning light “U”
This warning light comes on or flashes
if a problem is detected in the electri-
cal circuit monitoring the engine. If this
occurs, have a Yamaha dealer check
the self-diagnosis system. (See page
4-8 for an explanation of the self-diag-
nosis device.) The electrical circuit of
the warning light can be checked byturning 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 re-
mains on, have a Yamaha dealer check
the electrical circuit.
EAU26876
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
immobilizer system is enabled. After
24 hours have passed, the indicator
light will stop flashing, however the im-
mobilizer system is still enabled.
This model is also equipped with a
self-diagnosis device for the immobi-
lizer system. (See page 4-8 for an ex-
planation of the self-diagnosis device.)

OPERATION AND IMPORTANT RIDING POINTS
3. Start the engine by pushing the
start switch.
TIP
If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any one
attempt.
ECA11040
NOTICE
For maximum engine life, never ac-
celerate hard when the engine is
cold!
TIP
The engine is warm when it quickly re-
sponds to the throttle.
EAU16671
Shifting
1. Shift pedal
N. Neutral position
Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing
hills, etc.
The gear positions are shown in the il-
lustration.
TIP
To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it.

TIP
●Replace the air filter element more frequently if you are riding in unusually wet or dusty areas.
●Hydraulic brake service
●Regularly check and, if necessary, correct the brake fluid level.
●Every two years replace the internal components of the brake master cylinder, and change the brake fluid.
●Replace the brake hoses every four years and if cracked or damaged.

ECAM1060CAUTION:
The engine oil tank must be filled in
2 steps. First, fill the engine oil tank
with 1.90 L (2.0 US qt) (1.67 Imp.qt)
of the recommended engine oil.
Then, start the engine, race it 5 or 6
times, turn it off, and then add the
remainder of the engine oil.
NOTE:
Be sure to wipe off spilled oil on any
parts after the engine and exhaust
system have cooled down.
ECA11620CAUTION:  In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a
higher quality than specified. In
addition, do not use oils la-
beled “ENERGY CONSERVING
II” or higher.
 Make sure that no foreign ma-
terial enters the crankcase.
14. Start the engine, and then let it idle for several minutes while
checking it for oil leakage. If oil is
leaking, immediately turn the en-
gine off and check for the cause.
15. Turn the engine off, and then check the oil level and correct it if
necessary.
16. Install the engine guard by in- stalling the screws.
EAU20070
Coolant
The coolant level should be checked
before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
EAU20253
To check the coolant level1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.
NOTE:
The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the coolant reservoir.
Recommended engine oil:See page 8-1.
Oil quantity: Without oil filter element
replacement:2.50 L (2.64 US qt) (2.19 Imp.qt)
With oil filter element replacement: 2.60 L (2.73 US qt) (2.26 Imp.qt)

TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant reservoir
2. Maximum level mark
3. Minimum level mark
4. Reservoir cap
3. If the coolant is at or below the
minimum level mark, remove pan-
el E (See page 7-7.), remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap and the
panel. WARNING! Remove only
the coolant reservoir cap. Nev-
er attempt to remove the radia-
tor cap when the engine is hot.
NOTICE:If coolant is not avail-
able, use distilled water or soft
tap water instead. Do not use
hard water or salt water since it
is harmful to the engine. If wa-
ter has been used instead of
coolant, replace it with coolant
as soon as possible, otherwise
the cooling system will not be
protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the an-
tifreeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.
Coolant reservoir capacity
(up to the maximum level mark):
0.50 L (0.52 US qt) (0.44 Imp.
EAU33031
Changing the coolant
The coolant must be changed at the
intervals specified in the periodic
maintenance and lubrication chart.
Have a Yamaha dealer change the
coolant. WARNING! Never attempt
to remove the radiator cap when
the engine is hot.

WARNING0
●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.
●After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hiss-
ing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIP
If 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 low.
Check the cooling
system for leakage.
The coolant level
is OK.
There is
leakage.
There is no
leakage.
Have a Yamaha dealer check
and repair the cooling system.
Start the engine. If the engine overheats again, have
a Yamaha dealer check and repair the cooling system.
Add coolant. (See TIP.)
