TIPThis model is equipped with:  a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the display will indicate error
code 30, but this is not a malfunc-
tion. Turn the key to “OFF” and
then to “ON” to clear the error co-
d e . F ai l in g to do s o wi ll pr e v e nt the
engine from starting even though
the engine will crank when push-
ing the start switch.
 an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. In this case,
the display will indicate error code
70, but this is not a malfunction.
Push the start switch to clear the
error code and to restart the en-
gine.
EAU33016
Startin g the en gineIn order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
 The transmission is in the neutral
position.
 The transmission is in gear with
the clutch lever pulled and the
sidestand up.
See page 3-28 for more informa-
tion.
1. Turn the key to “ON” and make sure that the engine stop switch is
set to “ ”.
The following warning lights and
indicator lights should come on for
a few seconds, then go off. Oil level warning light
 Fuel level warning light
 Coolant temperature warning
light
 Shift timing indicator light
 Engine trouble warning light
 Immobilizer system indicator

14. Refill with the specified amount of
the recommended engine oil, and
then install and tighten the oil filler
cap.
TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.NOTICE
ECA11621
In or der to prevent clutch slip-
pa ge (since the en gine oil also
lu bricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a hi gh-
er quality than specifie d. In
a ddition, do not use oils lab eled
“ENERGY CONSERVING II” or
hi gher. 
Make sure that no forei gn mate-
rial enters the crankcase.
15. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.TIPAfter the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.NOTICE
ECA10402
If the oil level warnin g li ght flickers
or remains on even if the oil level is
correct, imme diately turn the en gine
off an d have a Yamaha dealer check
the vehicle.16. Turn the engine off, and then check the oil level and correct it if
necessary.
17. Install the cowling.
EAU20071
CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU3908A
To check the coolant level 1. Place the vehicle on a level surfa- ce and hold it in an upright posi-
tion.TIP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.TIPThe coolant should be between the mi-
nimum and maximum level marks.
Recommen ded en gine oil:
See page 8-1.
Oil quantity: Oil change:
2.40 L (2.54 US qt, 2.11 Imp.qt)

3. If the coolant is at or below the mi-
nimum level mark, remove panel B
to access the coolant reservoir.
(See page 6-8.)
4. Remove the coolant reservoir cap, add coolant to the maximum level
mark, and then install the reservoir
cap. WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the ra diator
cap when the en gine is hot.
[EWA15162]
NOTICE: If coolant is not
availa ble, use distille d water or
soft tap water instead . Do not
use har d water or salt water
since it is harmful to the en gine. If water has
been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has been
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e re duce d.

5. Install the panel.
EAU39006
To chan ge the coolant
1. Place the vehicle on a level surfa- ce and let the engine cool if neces-
sary.
2. Remove cowlings B and C. (See page 6-8.)
3. Place a container under the en- gine to collect the used coolant.
4. Remove the radiator cap. WARNING! Never attempt to re-
move the ra diator cap when the
en gine is hot.

its gasket to drain the cooling sys-
tem.

6. Move the hose clamp in the direc-
tion shown, and then disconnect
the radiator hose to drain the radi-
ator.
7. Remove the coolant reservoir by removing the bolts.
8. Remove the coolant reservoir cap, and then turn the coolant reservoir
upside down to empty it. 9. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the coolant reservoir by in- stalling the bolts.
11. Connect the radiator hose, and then move the hose clamp back to
its original position.
12. Install the coolant drain bolt and its new gasket, and then tighten
the bolt to the specified torque. 13. Pour the recommended coolant
into the reservoir to the maximum
level mark, and then install the
coolant reservoir cap.
14. Pour the recommended coolant into the radiator until it is full.
15. Install the radiator cap, start the engine, let it idle for several minu-
tes, and then turn it off.
16. Remove the radiator cap to check the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radi-
ator, and then install the radiator
cap.

Do not remove the ra diator cap when the en gine an d ra diator are hot. Scal din g hot flui d an d steam may be
b lown out un der pressure, which coul d cause serious injury. Be sure to wait until the en gine has coole d.
 Place a thick rag , like a towel, over the ra diator cap, an d then slowly rotate the cap counterclockwise to the
d etent to allow any resi dual pressure to escape. When the hissin g soun d has stopped , press down on the cap
while turnin g it counterclockwise, an d then remove the cap.TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended cool-
ant as soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
