Engine trouble warning light “
”
This warning light fl ashes or stays on
if an electrical 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.

WARNING
Be sure to stop the vehicle before
making any setting changes to the
multi-function display. Changing
settings while riding can distract
the operator and increase the risk
of an accident.
The multi-function display is equipped
with the following:● an odometer● a fuel reserve tripmeter (which
shows the distance traveled since
the bottom segment of the fuel
meter and fuel level warning indi-
cator started fl ashing)● two tripmeters (which show the
distance traveled since they were
last set to zero)● an oil change tripmeter (which
shows the distance traveled since
the last engine oil change)● an oil change indicator (which dis-
plays when the engine oil should
be changed)● a V-belt replacement tripmeter
(which shows the distance trav-
eled since the V-belt was last re-
placed)● a V-belt replacement indicator● an ambient temperature display● a clock● a fuel meter

Oil quantity:
0.2 L (0.21 US qt, 0.18 Imp.qt)8. Install the final transmission oil
fi ller cap and its new O-ring, and
then tighten the oil fi ller cap.
9. Check the fi nal transmission case
for oil leakage. If oil is leaking,
check for the cause.

CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specifi ed in the periodic maintenance
and lubrication chart.
EAUT3690
To check the coolant level
The coolant level should be checked
as follows before each ride. In addi-
tion, the coolant must be changed at
the intervals specified in the periodic
maintenance and lubrication chart.
1. Place the vehicle on the center-
stand.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 po-
sitioned straight up when check-
ing the coolant level. A slight tilt
to the side can result in a false

drain bolt and its new gasket, and
then tighten the bolt to the speci-
fi ed torque.Tightening torque:
Final transmission oil drain bolt:
20 Nm (2.0 m·kgf, 14.5 ft·lbf)7. Refi ll with the specifi ed amount of
the recommended fi nal transmis-
sion oil. WARNING! Make sure
that no foreign material enters
the final transmission case.
Make sure that no oil gets on
the tire or wheel.

5. Add coolant or distilled water to
raise the coolant to the maximum
level mark, and install the cool-
ant reservoir cap.
NOTICE:
If
coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine. If water has been
used instead of coolant, re-
place 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 antifreeze content
of the coolant as soon as pos-
sible, otherwise the effective-
ness of the coolant will be
reduced.

Changing the coolant
The coolant must be changed at the

Have a Yamaha dealer change the
coolant. WARNING! Never attempt
to remove the radiator cap when

WARNING
●
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot uid 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
detent 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.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
leakage.
There is
no leakage.
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.
