300 STARTING AND OPERATING

POWER TAKE OFF OPERATION ± IF EQUIPPED
The Dodge Chassis Cab vehicle, when equipped with
either the automatic 6 speed or manual G-56 6 speed
transmissions, will allow for an aftermarket upfit with a
transmission driven PTO (power take off). The customer
will have the ability to operate the PTO in either a
ªstationaryº or ªmobileº mode. The vehicles will be
factory set to the ªstationaryº mode. In order to select the
ªmobileº mode a DaimlerChrysler Dealership is required
to modify the vehicles settings using their proprietary
Dealer service tool.
Stationary Mode
To operate the PTO in this mode the vehicle must meet
the following conditions:
²Be in ªparkº position (vehicles equipped with auto-
matic transmission)
²Upfitter provider (on/off) switch has been activated
²Parking brake applied (vehicles equipped with
manual transmission)
²Vehicle must be running
²No vehicle, brake or clutch switch faults present
²PTO must be correctly installed using the vehicle
provided circuits
The customer has the choice to operate the PTO by
utilizing the cruise control switches or by utilizing a
remote control (provided by the PTO supplier). To oper-
ate the feature using the cruise control switches the
customer must first activate the up fitter provided on/off
switch. Next, the cruise control ªonº switch is selected.
Following this step the ªsetº switch must be depressed.
The vehicle is now in the PTO mode and is ready for use.
In order to increase or decrease the engine idle speed, to
optimize the PTO function, the ªaccelº and ªdecelº cruise
switches can be used respectively. To disengage PTO

operation and return to ªstandard vehicle operationº
simply turn the up fitter provided on/off switch to the off
position or press the ªcancelº cruise switch.
To operate the PTO via a remote switch the customer
must make sure the above conditions are met. It is vital
for proper operation that the PTO and remote have been
installed correctly paying special attention to ensure the
vehicle provided wiring has been connected properly.
This is the responsibility of the installer of the PTO and
switches/remote system. It is the responsibility of the
PTO manufacturer to ensure that their electrical (switches
and remote) system is compatible with the vehicle's
electrical architecture and software functionality.
Mobile Mode
To operate the PTO in this mode the vehicle must meet
the following conditions:
²Dealer selected ªmobileº mode activated via Dealer
proprietary service tool
²Upfitter provider (on/off) switch has been activated
²Vehicle must be in ªparkº or ªdriveº position (vehicles
equipped with automatic transmission)
²Parking brake must not be applied
²No vehicle, brake or clutch switch faults present
²Vehicle must be running
²PTO must be correctly installed using the vehicle
provided circuits
The customer may choose to use the PTO while the
vehicle is moving. To do so the PTO function must be
activated prior to taking the vehicle out of ªparkº. This is
accomplished by activating the up fitter provided PTO
on/off switch. At this point the customer may place the
vehicle in a forward or reverse gear and have PTO

Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Towing Tips Ð Automatic Transmission
The ªDº range can be selected when towing. However, if
frequent shifting occurs while in this range, the ªTOW
HAULº or ªOD/OFFº range should be selected.
NOTE:Using the ªTOW HAULº or ªOD/OFFº range
while operating the vehicle under heavy operating con-
ditions will improve performance and extend transmis-
sion life by reducing excessive shifting and heat build up.
This action will also provide better engine braking.

Recreational Towing Procedure Ð Manual Shift
Transfer Case Ð If Equipped
Use the following procedure to prepare your vehicle for
recreational towing:
CAUTION!
It is necessary to follow these steps to be certain that

recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop.
2. Shut OFF the engine.
3. Depress the brake pedal.
4. Shift automatic transmission to N (NEUTRAL), or
depress the clutch on manual transmissions.5. Shift transfer case lever into N (NEUTRAL).
6. Start the engine.
7. Shift automatic transmission into Reverse (R).
8. Release brake pedal for five seconds and ensure that
there is no vehicle movement.
9. Repeat steps 7 and 8 with the transmission in Drive
(D).
10. Shut OFF the engine and place the ignition key to the
unlocked OFF position.
11. Shift automatic transmission into P (PARK).
12. Apply the parking brake.
13. Attach vehicle to tow vehicle with tow bar.
14. Release the parking brake.
370 STARTING AND OPERATING

CAUTION!
Damage to the automatic transmission may occur if
the transmission is shifted into P (PARK) with the
transfer case in N (NEUTRAL) and the engine RUN-
NING. With the transfer case in N (NEUTRAL)
ensure that the engine is OFF prior to shifting the
transmission into P (PARK)
Returning to Normal Operation Ð Manual Shift
Transfer Case
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring the vehicle to a complete stop.
2. Apply the parking brake.
3. Shut OFF the engine.4. Depress the brake pedal.
5. Shift automatic transmission to N (NEUTRAL), or
depress the clutch on manual transmissions.
6. Shift transfer case lever to desired position.
7. Shift automatic transmission into P (Park).
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(NEUTRAL) position without first fully engaging the
parking brake. The transfer case N (NEUTRAL) po-
sition disengages both the front and rear driveshafts
from the powertrain and will allow the vehicle to
move regardless of the transmission position. The
parking brake should always be applied when the
driver is not in the vehicle.
