EBU26693Indicator lights and warning lights EBU17830Reverse indicator light“”
This indicator light comes on when the transmis-
sion is in the reverse position.EBU17860Neutral indicator light“”
This indicator light comes on when the transmis-
sion is in the neutral position.
EBU26702Coolant temperature warning light“”
This warning light comes on when the engine over-
heats. When this occurs during operation, stop the
engine as soon as it is safe to do so and allow it to
cool down for about 10 minutes.
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 re-
mains on, have a Yamaha dealer check the electri-
cal circuit.NOTICEECB00010The engine may overheat if the ATV is over-
loaded. In this case, reduce the load to spec-
ification.Start the engine after making sure that the
warning light is out. Continuous use while
the warning light is on may cause damage to
the engine.

EBU18101Start switch“”
Push this switch to crank the engine with the start-
er. See the starting instructions on page 6-1 prior
to starting the engine.EBU18152Light switch“//OFF”
Set this switch to“” to turn on the low beams
and the taillight. Set the switch to“” to turn on
the high beams and the taillight. Set the switch to
“OFF” to turn off all the lights.NOTICEECB00041Do not use the headlights with the engine
turned off for an extended period of time, oth-
erwise the battery may discharge to the point
that the starter motor will not operate properly.
If this should happen, remove the battery and
recharge it. See page 8-41 for battery charging
information.EBU18281Throttle lever Once the engine is running, movement of the throt-
tle lever will increase the engine speed.Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.
Before starting the engine, check the throttle to be
sure it is operating smoothly. Make sure it returns
to the idle position as soon as the lever is released.

nition such as the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When refueling,
be sure to insert the pump nozzle into the fuel
tank filler hole. Stop filling when the fuel reach-
es the bottom of the filler tube. Because fuel
expands when it heats up, heat from the en-
gine or the sun can cause fuel to spill out of
the fuel tank.
3. Wipe up any spilled fuel immediately.
NOTICE: Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since fuel may
deteriorate painted surfaces or plastic
parts.
[ECB00981]
4. Turn the fuel tank cap fully clockwise to make
sure it is securely closed.
