INSTRUMENT AND CONTROL FUNCTIONS
3-5
3If 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
following cycle will be repeated until
the malfunction is corrected: The fuel
level warning light will flash eight times,
and then go off for 3.0 seconds. If this
occurs, have a Yamaha dealer check
the vehicle.
EAU1142D
Coolant temperature warnin
g
li g ht “ ”
This warning light comes on if the en-
gine overheats. If this occurs, reduce
the load on the engine immediately. If
message “HI” flashes in the coolant
temperature display, stop the vehicle,
then stop the engine and let the engine
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
ECA10022
Do not continue to operate the en-
g
ine if it is overheatin g.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
6-46 for further instructions.

63. If the coolant is at or below the
minimum level mark, remove pan-
el B to access the coolant reser-
voir. (See page 6-8.)
4. Remove the coolant reservoir cap, 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 ra diator
cap when the en gine is hot.
[EWA15162]
NOTICE: If coolant is not
availa ble, use distille d water or
soft tap water instea d. Do not
use har d water or salt water
since it is harmful to the en gine. If water has
been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has been
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e re duce d.

To chan ge the coolant
1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove cowlings B and C. (See page 6-8.)
3. Place a container under the en- gine to collect the used coolant.
4. Remove the radiator cap. WARNING! Never attempt to re-
move the ra diator cap when the
en gine is hot.

its gasket to drain the cooling sys-
tem.

6. Move the hose clamp in the direc-
tion shown, and then disconnect
the radiator hose to drain the radi-
ator.
7. Remove the coolant reservoir by removing the bolts.
8. Remove the coolant reservoir cap, and then turn the coolant reservoir
upside down to empty it. 9. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the coolant reservoir by in- stalling the bolts.
11. Connect the radiator hose, and then move the hose clamp back to
its original position.
12. Install the coolant drain bolt and its new gasket, and then tighten
the bolt to the specified torque. 13. Pour the recommended coolant
into the reservoir to the maximum
level mark, and then install the
coolant reservoir cap.
14. Pour the recommended coolant into the radiator until it is full.
15. Install the radiator cap, start the engine, let it idle for several min-
utes, and then turn it off.
16. Remove the radiator cap to check the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radi-
ator, and then install the radiator
cap.

while turnin g it counterclockwise, an d then remove the cap.TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended cool-
ant 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,
