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 8-60.)
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 8-20.)NOTICEECB02120Hard water or salt water is harmful to the
engine. You may use soft water if you can-
not get distilled water.
EBU31770Final gear oilMake sure the final gear oil is at the specified
level. Add oil as necessary. (See page 8-16
for details.)
If desired, an SAE 80W-90 hypoid gear oil
may be used for all conditions.TIPGL-4 is a quality and additive rating; GL-5 or
GL-6 rated hypoid gear oils may also be used. EBU31780Differential gear oilMake sure the differential gear oil is at the
specified level. Add oil as necessary. (See
page 8-18 for details.)
Coolant reservoir capacity (up to the maxi-
mum level mark):0.28 L (0.30 US qt, 0.25 Imp.qt)
Recommended oil:SAE 80 API GL-4 Hypoid gear oil
Recommended oil: SAE 80 API GL-4 Hypoid gear oil

4. Install the differential gear oil drain boltand its new gasket, and then tighten the
bolt to the specified torque.
5. Refill the differential gear case with the recommended oil. NOTICE: Be sure no
foreign material enters the differential
gear case.

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.
EBU32391CoolantThe coolant level should be checked before
each ride. In addition, the coolant must be
changed at the intervals specified in the peri-
odic maintenance and lubrication chart.
Checking the coolant level1. 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.

WARNING
EWB01891Wait for the engine and
radiator to cool be-
fore removing the radiator cap. You could
be burned by hot fluid and steam blown
out under pressure. Always place a thick
rag over the cap when opening. Allow any
remaining pressure to escape before com-
pletely removing the cap. 1. Park the vehicle on a level surface.
2. Remove the hood. (See page 8-10 for hood removal and installation proce-
dures.)
3. Remove the right rear panel. (See page 8-11 for right rear panel removing and in-
stalling procedures.)
4. Place a container under the engine to col- lect the used coolant.
5. Remove the radiator cap.

9. Disconnect the coolant reservoir hose,and then drain the coolant from the cool-
ant reservoir.
10. After draining the coolant, thoroughly flush the cooling system with clean tap
water.
11. Install the coolant drain bolt and its new gasket and then tighten the bolt to the
specified torque. 12. Connect the coolant reservoir hose.
13. Pour the recommended coolant into the
radiator until it is full.
14. Pour the recommended coolant into the
reservoir to the maximum level mark, and
then install the reservoir cap.
NOTICEECB02190Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling. Do not
use hard water or salt water since they are
harmful to the engine.
