ers and clothes dryers. Gasoline can catch
fire and you could be burned.
When transporting the ATV in another vehi-
cle, be sure it is kept upright. Otherwise, fuel
may leak out of the fuel tank.Gasoline is poisonous. If you should swal-
low some gasoline or inhale a lot of gasoline
vapor, or get some gasoline in your eyes,
seek medical help immediately. If gasoline
spills on your skin, wash with soap and wa-
ter. If gasoline spills on your clothing,change your clothes.

cool down for about 10 minutes.
The electrical circuit of the warning light can be
checked by turning the key to “ON”. If the warning
light does not come on, have a Yamaha dealer
check the electrical circuit.CAUTION:ECB00891The engine may overheat if the ATV is over-
loaded. In this case, reduce the load to spec-
ification.

The engine may also overheat if mud or dirt
has accumulated on the radiator (i.e., after
riding in wet terrain). In this case, see page
8-19 for an explanation on how to access the
radiator.Start the engine after making sure that the
warning light is out. Continuous use while
the warning light is on may cause damage tothe engine.EBU27280Engine trouble warning light “”
This warning light comes on or flashes when an
electrical circuit monitoring the engine is defective.
When this occurs, have a Yamaha dealer check
the self-diagnosis system. (See page 4-5 for an ex-
planation 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, then go off, have a
Yamaha dealer check the electrical circuit.EBU27542Electric Power Steering warning light “EPS”
This warning light comes on when the key is turned
to “ON”, and then goes off once the engine is start-
ed. If the warning light remains on or comes on af-ter the engine is started, the EPS system may be
defective. When this occurs, have a Yamaha deal-
er check the EPS 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, have a Yamaha dealer
check the electrical circuit.
NOTE:If the engine is stopped using the engine stop
switch and the key is in the “ON” position, the
EPS warning light comes on to indicate that the
power assistance for the steering is not function-
ing.If the steering load is too heavy (i.e., excessive
steering use when the ATV is traveling at a slow
speed), the power assist is reduced to protectthe EPS motor from overheating.EBU17961On-Command four-wheel-drive/differential
gear lock indicator “”/“”
