The vehicle may have power take-off (PTO). The PTO switch is located on the instrument panel.
An indicator in the switch comes on to show PTO is active. See High Idle System for more information.
A PTO is a gearbox or mechanical device used to transmit mechanical power from the powertrain, through gears or a transmission, to another mechanical or hydraulic device. Before using a PTO, refer to the manufacturer's or installer's instructions.
