CONTROLS AND INSTRUMENTS
PTO is a device that is used to provide engine power to special equipment directly from
the engine or through the transmission. This manual describes an operation of PTO,
but for an operation of special equipment other than the PTO lever and PTO switch,
consult [Instruction Manual for Special Equipment].
CAUTION
• Make sure that there are no persons or objects around and above the vehicle
before operating PTO.
• Operate PTO on a level surface.
• When operating the PTO and special equipment, be sure to place the gearshift
lever into the "N" position, firmly pull the parking brake lever and keep the brake
pedal fully depressed with your right foot.
• Do not operate PTO and/or special equipment while the vehicle is moving.
• For operation of special equipment, consult the separate
for Special Equipment].
ADVICE
• The PTO of the AMT model cannot be engaged when the engine speed is
800 r/min or higher to prevent a failure of the system. However, the PTO can
be engaged at engine speeds of up to 1,200 r/min during diesel particulate
defuser (DPD) regeneration or upon startup of a cold engine (when the quick-
warm system is activated). The PTO cannot be engaged during fast idle control
immediately after cold engine startup or when the engine speed is increased
with the idling control knob. Wait until engine warm up completes or return the
idling control knob to the lowest setting before operating the PTO switch.
• While operating the PTO of the vehicle equipped with DPD, the DPD system
will continue to filter the exhaust and accumulate soot. The engine control
system, depending on the speed and load being applied by the PTO, may
not be able to generate enough energy or adequate heat needed to clean or
regenerate the filter. Continued operation under conditions that do not allow
effective regeneration or cleaning will eventually plug the filter and result in
reduced power. The check engine warning light will be displayed, and dealer
service will be required to return the vehicle to normal operation. To prevent
this from occurring, frequently monitor the vehicle during PTO operation, paying
particular attention to the DPD manual regeneration indicator light (amber) if the
vehicle is not equipped with multi-information display (MID) or the "PUSH DPD
SWITCH" message (amber) if the vehicle is equipped with MID.
