minutes, and then turn the key to
“ON”.
3. If the warning light comes on and
does not go off, check the engine
oil level. (See page 6-9.) If the
warning light still stays on after
confirming the oil level is correct,
have a Yamaha dealer check the
vehicle.
TIP

This warning light WILL NOT come on:

when the engine is idling

when riding

if the engine has stalled and the
key has not been turned from “ON”
to “OFF” and then back to “ON”
HOWEVER, if the warning light is on
when the engine is started, it will stay
on until the key is turned to “OFF”.
EAU11350
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”.
If the warning light does not come on
for a few seconds, then go off, have a
Yamaha dealer check the electrical cir-
cuit.
EAU11442
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”.
If the warning light does not come on
for a few seconds, then go off, have a
Yamaha dealer check the electrical cir-
cuit.
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 tothe coolant temperature in the ra-
diator.

If the engine overheats, see page
6-38 for further instructions.
EAU46440
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 3-13
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 for a few seconds, then go off, have
a Yamaha dealer check the electrical
circuit.
TIP

This warning light will come on when
the key is turned to “ON” and the start
switch is pushed, but this does not indi-
cate a malfunction.

Coolant
The 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.
EAU46690
To check the coolant level
1. Place the vehicle on a level sur-
face 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 temperature.

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 cool-
ant reservoir.
TIP

The coolant should be between the
minimum and maximum level marks.3. 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 wateror 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.
EAU46422
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove cowling A. (See
page 6-6.)

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.

[EWA10381]
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 bolt 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 bolt.
TIP

Check the O-ring for damage and re-
place it if necessary.
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.
17. 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.

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.
TIP

If 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.
