6 Shifting: Neutral to Reverse and Reverse to
Park
TIPThe drive select lever cannot be shifted into or fromreverse or park without applying the brake pedal.
1. Bring the ATV to a complete stop.
2. Apply the brake pedal.
3. Shift from neutral to reverse or from reverse to
park and vice versa by moving the drive select
lever along the shift guide.
TIP
When in reverse, the reverse indicator light
should come on. If the indicator light does not
come on, have a Yamaha dealer check the elec-
trical circuit.
Due to the synchronizing mechanism in the en-
gine, the indicator light may not come on until theATV starts moving.
4. Check behind for people or obstacles, and
then release the brake pedal.
5. Open the throttle lever gradually and continue
to watch to the rear while backing.
WARNING
EWB00720Improper operation in reverse could make you
hit an obstacle or even a person behind you,
resulting in serious injury. When you shift into
reverse, make sure there are no people or ob-
stacles behind you. When it is safe to proceed,go slowly.
