●
This model is also equipped with a
self-diagnosis device for the oil
level detection circuit. If a problem
is detected in the oil level detection
circuit, the following cycle will be
repeated until the malfunction is
corrected: The oil level warning
light will flash ten times, then go off
for 2.5 seconds. If this occurs,
have a Yamaha dealer check the
vehicle.
EAU48700
Fuel level warning light “ ”
This warning light comes on when the
fuel level drops below approximately
3.9 L (1.03 US gal, 0.86 Imp.gal). When
this occurs, refuel as soon as possible.
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.
TIPThis model is also equipped with a self-
diagnosis device for the fuel level de-
tection circuit. If a problem is detected
in the fuel level detection circuit, the fol-
lowing cycle will be repeated until the
malfunction is corrected: The fuel level
warning light, the fuel meter and the
fuel level warning indicator will flash
eight times, and then go off for 3.0 sec-
onds. If this occurs, have a Yamaha
dealer check the vehicle.
EAU11446
Coolant temperature warning
light “ ”
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 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.
NOTICE
ECA10021
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
6-42 for further instructions.
EAU42774
Engine trouble warning light “ ”
This warning light comes on if a prob-
lem is detected in the electrical circuit
monitoring the engine. If this occurs,
have a Yamaha dealer check the self-
diagnosis system. (See page 3-16 for
an explanation of the self-diagnosis de-
vice.)
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.

63. If the coolant is at or below the
minimum level mark, remove the
coolant reservoir cap guard by re-
moving the bolt, and then remove
the reservoir cap.
4. 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 radiator
cap when the engine is hot.
[EWA15161]
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, replace it with cool-
ant as soon as possible, other-
wise 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 anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.
[ECA10472]
5. Install the coolant reservoir cap
guard by installing the bolt.
EAU46423
To change the coolant1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove cowling A. (See page 6-8.) 3. Remove the air intake duct by re-
moving the bolts.
4. Place a container under the engine to collect the used coolant.
5. Remove the radiator cap. WARNING! Never attempt to re-
move the radiator cap when the
engine is hot.

6. Remove the coolant reservoir cov-
er and coolant reservoir by remov-
ing the bolts. 7. Remove the coolant reservoir cap
guard by removing the bolt, and
then remove the reservoir cap.
8. Drain the coolant from the coolant reservoir by turning it upside down.
9. Install the coolant reservoir cover and the coolant reservoir by plac-
ing them in their original position,
and then installing the bolts.
10. Remove the coolant drain screw and its O-ring to drain the cooling
system.
11. After the coolant is completely drained, thoroughly flush the cool-
ing system with clean tap water.
12. Install the coolant drain screw and its new O-ring. 13. Hold the vehicle upright, and pour
the specified amount of the recom-
mended coolant into the radiator
and reservoir. NOTICE: Failing to
hold the vehicle upright when
filling the radiator with coolant
may cause air to be trapped in
the cooling system.
[ECA16540]
14. Install the coolant reservoir cap, and then install the reservoir cap
guard by installing the bolt.
15. Install the radiator cap.
16. Start the engine, let it idle for sev- eral minutes, and then turn it off.

617. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap.
18. Check the coolant level in the res- ervoir. If necessary, remove the
coolant reservoir cap guard and
the cap, add coolant to the maxi-
mum level mark, and then install
the cap and the cap guard.
19. Start the engine, and then check the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
20. Install the air intake duct by install- ing the bolts.
21. Install the cowling.

If a fuse is blown, replace it as follows.
1. Turn the key to “OFF” and turn off the electrical circuit in question.
2. Remove the blown fuse, and then install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher amperage
rating than recommended to avoid causing extensive dam-
age to the electrical system and
possibly a fire.

Engine overheating
WARNING
EWAT1040
●
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.
●
Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the de-
tent 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.
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.
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.
