Engaging PTO
To activate and engage the PTO use the following steps:
1. Stop your vehicle.
2. Shift the transmission to NEUTRAL (N)
or PARK (P).
3. Move the PTO switch (cruise control switch,
if equipped) to the on position.
4. Press the PTO enable switch on the instrument panel.
The engine speed will increase to the PTO standby
speed, a factory default setting of 1,200 rpm. This
speed is intended for engagement only, this is not an
operation speed.
Engagement procedures could vary, so before
engaging PTO, refer to the PTO manufacturer or
installer's instructions.
You can now use the PTO controls (cruise controls) to
operate/regulate PTO speeds.
