Fuel level warnin
g li ght “ ”
This warning light comes on when you
are low on fuel. When the fuel level
drops below approximately 3.4 L (0.90
US gal, 0.75 Imp.gal), the light will
come on to remind you to refuel as
soon as possible.
When the vehicle is turned on, the light
will perform a circuit check (come on
for a few seconds and then go off).
If the warning light does not come on
during the circuit check, or if the warn-
ing light remains on after refueling,
have a Yamaha dealer check the vehi-
cle.TIPIf a malfunction is detected, the fuel
level warning light will flash repeatedly.
Have a Yamaha dealer check the vehi-
cle.

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 ve-
hicle 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 vehicle is turned on,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.NOTICE

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
7-42 for further instructions.

Engine trou ble warnin g li ght “ ”
This warning light comes on if a prob-
lem is detected in the engine or other
vehicle control system. If this occurs,
have a Yamaha dealer check the on-
board diagnostic system.TIPWhen the vehicle is turned on, the light
will come on for a few seconds and
then go off. If the light does not come
on, or if the light remains on, have a

CoolantThe coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.TIPIf genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.
EAU3908B
To check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold.
1. Park the vehicle on a level surface. 2. With the vehicle in an upright posi-
tion, look at the coolant level in the
reservoir.
3. If the coolant is at or below the minimum level mark, remove pan-
el B to access the coolant reser-
voir. (See page 7-9.)
4. Remove the coolant reservoir cap. WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the ra diator
cap when the en gine is hot.
[EWA15162]
5. Add coolant to the maximum level
mark. NOTICE: If coolant is not
availa ble, use d istilled 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.

WARNING
EWAT1041
Do not remove the ra diator cap when the en gine an d ra diator are hot. Scal din g hot flui d an d steam may be
b lown out un der pressure, which coul d cause serious injury. Be sure to wait until the en gine has coole d.
 Place a thick ra g, like a towel, over the ra diator cap, an d then slowly rotate the cap counterclockwise to the
d etent to allow any resi dual pressure to escape. When the hissin g soun d has stoppe d, press down on the 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,
have a
Yamaha dealer check
and repair the cooling system.
