NOTICEECB00891
The engine may overheat if the ATV is over-
loaded. In this case, reduce the load to spec-
ification.

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 to
the engine.EBU27284Engine trouble warning light“”

ed. If the warning light remains on or comes on af-
ter the engine is started, the EPS system may not
be working correctly. When this occurs, have a
Yamaha dealer 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-

turning the key to “ON” while the button is pushed,
switches the display between “mph” and “km/h”.Clock mode
