Throttle Lever - Yamaha GRIZZLY 450 YFM450DF Owner's Manual

1. On-Command differential gear lock switch
"4WD"/"LOCK"
To release the differential gear lock, stop the ATV
and push the switch to the "4WD" position.
TIP
 When the switch is set to "LOCK", the differen-
tial gear lock indicator and indicator light will
flash until the differential gear is locked.
 When the indicator and indicator light are flash-
ing, turning the handlebar back and forth will
help the differential gear lock to engage.
 Riding before the differential gear lock is prop-
erly engaged (e.g., when the indicator and indi-
cator light are flashing) will cause the vehicle
speed to be limited until engagement is com-
plete.
 When the ATV is in four-wheel-drive differential
gear lock, the maximum traveling speed is limit-
ed to 35 km/h (22 mi/h). However, if conditions
require full engine power to be available, push
and hold the override switch to disable the dif-
ferential gear lock speed limiter. (See page 4-8
for a detailed explanation of this switch.)

Throttle lever

Once the engine is running, pushing the throttle le-
ver will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine
will return to an idle any time the throttle lever is re-
leased.
