EBU31330Coolant temperature warning light “ ”
If the coolant temperature reaches a specific
level, this light comes on to warn that the
coolant temperature is too hot. If the light
comes on during operation, stop the engine
as soon as it is safe to do so and allow the en-
gine to cool down for about 10 minutes. (See
page 8-57.)
The electrical circuit of the warning light can
be checked by turning the key to “ ” (on). 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.NOTICEECB02040The engine may overheat if the vehicle is
overloaded. If this happens, reduce the
load to specification. 
After restarting, make sure that the
warning light is out. Continuous use
while this warning light is on may cause
damage to the engine.
EBU31340Engine trouble warning light “ ”
This warning light comes on or flashes if a
problem is detected in the electrical circuit
monitoring the engine. When this occurs,
have a Yamaha dealer check the self-diagno-
sis system. (See page 4-10 for an explanation
of the self-diagnosis device.)
The electrical circuit of the warning light can
be checked by turning the key to “ ” (on). 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.

EBU31760CoolantCheck the coolant level in the coolant reser-
voir when the engine is cold (the coolant level
will vary with engine temperature).
The coolant level is satisfactory if it is be-
tween the minimum and maximum level
marks on the coolant reservoir. If the coolant
level is at or below the minimum level mark,
add additional coolant to bring the level up to
maximum level mark. If coolant is not avail-
able, add distilled water. Change the coolant
every two years. (See page 8-21.)NOTICEECB02120Hard water or salt water is harmful to the
engine. You may use soft water if you can-
not get distilled water.
EBU36020Final gearMake sure there is no oil leaking from the final
gear case.EBU36030Differential gearMake sure there is no oil leaking from the dif-
ferential gear case.EBU31790Accelerator pedalCheck to see that the accelerator pedal oper-
ates correctly. It must operate smoothly and
spring back to the idle position fully when re-
leased. Have a Yamaha dealer repair as nec-
essary for proper operation.EBU31800Seat beltsMake sure that the seat belts are not frayed,
torn, stretched, or damaged. The seat belts
must move smoothly when pulled out and re-
tract on its own when released. The seat belts
must also lock up when quickly pulled out.
Coolant reservoir capacity (up to the maxi-
mum level mark): 0.28 L (0.30 US qt, 0.25 Imp.qt)

6. Check the oil filler bolt gasket for dam-age, and replace it if necessary.
7. Install the differential gear oil filler bolt and its gasket, and then tighten the bolt
to the specified torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.EBU32990CoolantThe coolant level should be checked before
each ride.
Checking the coolant level
1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture.
TIPThe coolant should be between the minimum
and maximum level marks. 3. If the coolant is at or below the minimumlevel mark, remove the coolant reservoir
cap, add coolant to the maximum level
mark, install the reservoir cap.

Changing the coolant
The coolant must be changed by a Yamaha
dealer at the intervals specified in the periodic
maintenance and lubrication chart.
Adding water instead of coolant lowers the
antifreeze content of the coolant. If water is
used instead of coolant, have a Yamaha deal-
er check the antifreeze content of the coolant
as soon as possible.
The radiator fan is automatically switched on
or off according to the coolant temperature in
the radiator.NOTICEECB02260Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling.
If your vehicle overheats, see page 8-57 for
instructions.EBU32400Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIPIf it is difficult to get the recommended coolant, tap water can be used temporarily, provided that
it is changed to the recommende d coolant as soon as possible. Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.
