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.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.

Override switch “OVERRIDE”
Top speed is normally limited when operating in
4WD-LOCK. If conditions require more engine
power when riding forward, push and hold this
switch to override the 4WD-LOCK speed limiting
function. (See page 4-31 for a detailed explanation
about the differential gear lock switch and its func-
tion.) Releasing the switch restores the speed lim-
iting function.
While this switch is pushed, the segments of the
speedometer digits will appear as shown in the fig-
ure.NOTE:_ If the digits of the speedometer appear as shown
when the switch is NOT being pushed, this could
indicate a malfunction in the electrical system. In
this case, take the ATV to a Yamaha dealer at the
first opportunity. _

On-command four-wheel drive and differential
gear lock switches
This ATV is equipped with an on-command four-
wheel drive switch “2WD”/“4WD” and a differential
gear lock switch “LOCK”/“4WD”. Select the appro-
priate drive according to terrain and the conditions.

Two-wheel drive (2WD): Power is supplied to
the rear wheels only.


Four-wheel drive (4WD): Power is supplied to
the rear and front wheels.


Four-wheel drive with the differential gear
locked (4WD-LOCK): Power is supplied to the
rear and front wheels when the differential gear
is locked (“DIFF.LOCK”). Unlike the 4WD
mode, all wheels turn at the same speed.

Differential gear lock switch “LOCK”/“4WD”
To lock the differential gear in 4WD, make sure the
on-command four-wheel-drive switch is set to
“4WD”, stop the ATV, move the lever to position
b, and then set the switch to “LOCK”. When the
differential gear is locked, the differential gear lock
indicator (“DIFF.LOCK”) light will come on along
with the indicator “” in the speedometer unit
display.
To release the differential gear lock, stop the ATV
and set the switch to “4WD”.
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. _

NOTE:_

When the switch is set to “LOCK”, the differ-
ential gear lock indicator light will flash until
the differential gear is locked.


When the indicator light is flashing, turning
the handlebar back and forth will help the dif-
ferential gear lock to engage.


Riding before the differential gear lock is
properly engaged (e.g., when the indicator
light is flashing) will cause the engine speed
to be limited until engagement is complete.


When the ATV is in 4WD-LOCK, the maxi-
mum traveling speed is limited to 35 km/h.
However, if conditions require full engine
power to be available, push and hold the
override switch to disable the “4WD-LOCK”
speed limiter. (See page 4-21 for a detailed
explanation of this switch.)
