Yamaha YFM450FAT Owner's Manual page 31

NOTE:
_
If the digits of the speedometer appear as
shown when the switch is NOT being pushed,
this could indicate a malfunction in the electri-
cal system. In this case, take the ATV to a
Yamaha dealer at the first opportunity.
_
POTENTIAL HAZARD
Riding too fast while the ATV is in
4WD-LOCK.
WHAT CAN HAPPEN
All wheels turn at the same speed when
the differential 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.
HOW TO AVOID THE HAZARD
Always ride at a slow speed when the
ATV is in 4WD-LOCK, and allow extra
time and distance for maneuvers.
