To release the differential gear lock, stop the ATV
and push the switch to the “4WD” position.
TIP
If the differential gear lock is not engaging prop-
erly, turn the handlebar back and forth to help it
engage.

ly engaged will cause the vehicle speed to be
limited until engagement is complete.
When the ATV is in four-wheel-drive differential
gear lock, the maximum traveling speed is limit-
ed to 31 km/h (19 mi/h). However, if conditions
require full engine power to be available, push
and hold the override switch to disable the differ-
ential gear lock speed limiter. (See page 4-6 for
a detailed explanation of this switch.)
