● 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
8-20 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 to
the engine.
EBU27280
Engine 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.
EBU29060
Electric Power Steering warning light “EPS”
(for EPS model)
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.
TIP
● 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 protect
the EPS motor from overheating.
