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 8-63.)
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 8-25.)NOTICEECB02120Hard water or salt water is harmful to the
engine. You may use soft water if you can-
not get distilled water.
EBU31771Final gear oilMake sure the final gear oil is at the specified
level. Add oil as necessary. (See page 8-20
for details.)
If desired, an SAE 80W-90 hypoid gear oil
may be used instead.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 8-22 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

10–20 hours:
Avoid prolonged operation above three-quar-
ter throttle.
After break-in:
The vehicle may now be operated normally.EBU33081Starting the engine1. Turn the key to “ ” (on).NOTICEECB02291The coolant temperature warning light and
engine trouble warning light should come
on, then go off.
The EPS warning light should come on,
then go off when the engine is started.
To avoid possible damage, do not operate
the vehicle if a warning light does not work
as described above. 2. Apply the brake pedal.
3. Shift the drive select lever into the neutralposition. 
When the drive select lever is in the
neutral position, the neutral indicator
light should come on. If the neutral indi-
cator light does not come on, ask a
Yamaha dealer to inspect the electric
circuit.
 The engine can be started in any gear if
the brake pedal is applied. However, it
is recommended to shift into neutral
before starting the engine.
4. With your foot off the accelerator pedal,
start the engine by turning the key to “ ”
(start).
If the engine fails to start, release the key, and
then try starting it again. Wait a few seconds
before the next attempt. Each attempt should
be as short as possible, to preserve battery
energy. NOTICE: Do not crank the engine
more than 5 seconds on each attempt, or
starter damage could occur. Wait at least
5 seconds between each operation of the
electric starter to let it cool.
