WARNING
_
Always stop the ATV before changing from
2WD to 4WD, or from 4WD to 4WD-LOCK, or
vice-versa.
The ATV handles differently in 2WD than in
4WD and in 4WD-LOCK in some circumstanc-
es. Changing from 2WD to 4WD, or from 4WD
to 4WD-LOCK, or vice-versa while moving may
cause the ATV to unexpectedly handle differ-
ently. This could distract the operator and in-
crease the risk of losing control and an
accident.
