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.CAUTION:_

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


After restarting, make sure that the light is
out. Continuous use while the light is on
may cause damage to the engine.

WARNING
_ Always ride at a slow speed when the ATV is in
4WD-LOCK, and allow extra time and distance
for maneuvers.
All wheels turn at the same speed when the dif-
ferential is locked, so it takes more effort to
turn the ATV. The amount of effort is more the
faster you go. You may lose control and have
an accident if you cannot make a sharp
enough turn for the speed you are traveling. _
