Coolant temperature warning light “”
When the coolant temperature reaches a specified
level, this light comes on to warn that the coolant
temperature is too hot. If the light comes on during
operation, stop the engine as soon as it is safe to
do so and allow the engine to cool down for about
10 minutes.
To check the coolant temperature warning light,
shift the drive select lever into neutral, turn the key
to “ON”, and then press the start switch. If the light
does not come on, have a Yamaha dealer inspect
the electrical circuit.CAUTION:_

The engine may overheat if the ATV is
overloaded. If this happens, reduce the
load to specification.


Restart after making sure that the light is
out. Continuous use while the light is on
may cause damage to the engine.

To change from two-wheel drive (2WD) to four-
wheel drive (4WD), stop the ATV and set the
switch to the 4WD position.
To change from four-wheel drive (4WD) to two-
wheel drive (2WD), stop the ATV and set the
switch to the 2WD position.
WARNING
_ Always stop the ATV before changing from
2WD to 4WD or from 4WD to 2WD. The ATV
handles differently in 2WD than in 4WD in
some circumstances. Changing from 2WD to
4WD or vice-versa while moving may cause
the ATV to unexpectedly handle differently.
This could distract the operator and increase
the risk of losing control and an accident. _
