and/or turn the steering wheel back and
forth to help the differential to lock or un-
lock. EBU34932Shift light
This light can be set to come on and go off at
the desired engine speeds and is used to in-
form the driver when it is time to upshift.
The electrical circuit of the shift light can be
checked by turning the key to “ ” (on). If the
light does not come on initially when the key
is turned to “ ” (on), or if the light remains
on, have a Yamaha dealer check the electrical
circuit.TIPSee page 5-13 for an explanation of how to
set the shift light.
EBU35283Coolant temperature warning light “ ”
This warning light comes on when the coolant
temperature, and therefore the engine, is out-
side its normal operating temperature range.
The warning light comes on in blue to inform
the driver that the vehicle should be warmed
up. After the engine is started, warm it up until
the warning light goes off.
The vehicle can be operated normally when
the warning light is off.
The warning light comes on in red when the
engine is overheating. If the red light comes
on, stop the vehicle as soon as it is safe to do
so and allow the engine to idle for about 10
minutes. If the warning light does not go off,
stop the engine and allow it to cool. (See page
9-69.)TIPIf you continue to driv e the vehicle while the
engine is overheating, a buzzer will sound.

The coolant temperature warning light can
be checked by turning the key to “ ” (on).
The warning light should come on in purple
briefly (which confirms that both the blue
and red indicators are okay) and then go
off. If the warning light does not come on at
all, comes on in red or blue, or if the warning
light remains on, have a Yamaha dealer
check the vehicle. 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.
EBU31342Engine 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, the
display will indicate an error code (see page
5-15). Have a Yamaha dealer check the self-
diagnostic system.
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

TIPThis fuel gauge is equipped with a self-diag-
nostic system. If a problem is detected in an
electrical circuit, all the display segments will
flash repeatedly. If this occurs, have a
Yamaha dealer check the electrical circuit. Transmission gear display
This display shows the selected gear. The
neutral position is indicated by “N” and by the
neutral indicator light “N”. Shift light control mode
The shift light has three settings which can be
adjusted.

Flashing pattern: this function allows you to
choose whether or not the light will come
on and whether it should flash or stay on
when activated.

Clutch fluid
Depress and release the clutch pedal five
times. Check to see if any fluid is leaking out
of the hoses, reservoir, or master cylinder.
Check the clutch fluid level and correct if nec-
essary. (See page 9-47.)TIPIf any leakage is found, or if the clutch pedal
offers little resistance, have a Yamaha dealer
service the vehicle. EBU36972FuelMake sure there is sufficient fuel in the tank.
Refuel if necessary.
WARNING
EWB02522Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and ex-
plosions and to reduce the risk of injury
when refueling, follow these instructions.
1. Before refueling, turn off the engine andbe sure that no one is sitting in the vehi-
cle.
Never refuel while smoking, or while in
the vicinity of sparks, open flames, or
other sources of ignition such as the pilot
lights of water heaters and clothes dry-
ers.
2. Do not overfill the fuel tank. Because fuel expands when it heats up, heat from the
engine or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel immediately.
4. Be sure the fuel tank cap is closed se- curely.
WARNING
EWB02532Gasoline is poisonous and can cause inju-
ry or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline or inhale a
lot of gasoline vapor, or get some gasoline
in your eyes, see your doctor immediately.

EBU35690Shift leverThe shift lever should move smoothly both
forward and backwards and return to its orig-
inal position after a gear change is made.
Check the shift lever and transmission for
roughness before starting off.TIPThe engine may need to be started for the
transmission to engage gears. EBU31832Fittings and fastenersAlways check the tightness of chassis fittings
and fasteners before starting off. Take the ve-
hicle to a Yamaha dealer or refer to the Servi-
ce Manual for correct tightening torque.EBU31840Instruments, lights and switchesCheck that all instruments, lights and switch-
es are working properly. Correct if necessary.
EBU31851Control cablesWhen driving in cold weather, always make
sure all control cables work smoothly before
starting off. WARNING! Control cables can
freeze in cold weather and you could be
unable to control the vehicle.

EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
checked, preferably by a Yamaha dealer.
Since heat and deposits will cause any spark
plug to slowly erode, the spark plugs should
be removed and checked in accordance with
the periodic maintenance chart for the emis-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine. The porcelain insulator around the center
electrode of each spark plug should be a me-
dium-to-light tan color (the ideal color when
the vehicle is ridden normally), and all spark
plugs installed in the engine should have a
similar color. If any spark plug shows a dis-
tinctly different color, the engine could be op-
erating improperly. Do not attempt to
diagnose such problems yourself. Instead,
have a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode ero-
sion and excessive carbon or other deposits,
it should be replaced.
Before installing a spark plug, the spark plug
gap should be measured with a wire thick-
ness gauge and, if necessary, adjusted to
specification.1. Rear axle boot
