Preferred Procedure
1. With engine RUNNING, slow vehicle to 2 to 3 mph (3
to 5 km/h).
2. Shift the transmission into NEUTRAL (depress clutch
on manual transmissions).
3. While still rolling, rotate the transfer case control
switch to the desired position.
4. After the desired position indicator light is ON (not
flashing), shift transmission back into gear (release clutch
on manual transmissions).
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the key ON and the engine either OFF or
RUNNING, shift the transmission into NEUTRAL (de-
press clutch on manual transmissions). 3. Rotate the transfer case control switch to the desired
position.
4. After the desired position indicator light is ON (not
flashing), shift transmission back into gear (release clutch
on manual transmissions).
NOTE: If steps 1 or 2 of either the Preferred or Alternate
Procedure are not satisfied prior to attempting the shift
then the desired position indicator light will flash con-
tinuously while the original position indicator light is
ON, until all requirements have been met.
NOTE: The ignition key must be ON for a shift to take
place and for the position indicator lights to be operable.
If the key is not ON then the shift will not take place and
no position indicator lights will be on or flashing.

POWER TAKE OFF OPERATION – IF EQUIPPED
The 3500 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
“stationary” or “mobile” mode. The vehicles will be
factory set to the “stationary” mode. In order to select the
“mobile” 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:
• Be in “park” position (vehicles equipped with auto-
matic transmission)
• Upfitter provider (on/off) switch has been activated • Parking brake applied (vehicles equipped with
manual transmission)
• Vehicle must be running
• No vehicle, brake or clutch switch faults present
• PTO 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 “on” switch is selected.
Following this step the “set” 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 “accel” and “decel” cruise
switches can be used respectively. To disengage PTO296 STARTING AND OPERATING

operation and return to “standard vehicle operation”
simply turn the up fitter provided on/off switch to the off
position.
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: • Dealer selected “mobile” mode activated via Dealer
proprietary service tool
• Upfitter provider (on/off) switch has been activated
• Vehicle must be in “park” or “drive” position (vehicles
equipped with automatic transmission)
• Parking brake must not be applied
• No vehicle, brake or clutch switch faults present
• Vehicle must be running
• PTO 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 “park”. 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 STARTING AND OPERATING 297

If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Towing Tips — Automatic Transmission
The “D” range can be selected when towing. However, if
frequent shifting occurs while in this range, the “TOW
HAUL” or “OD/OFF” range should be selected.
NOTE: Using the “TOW HAUL” or “OD/OFF” 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.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See Schedule “B” in
section 8 of this manual for transmission fluid change
intervals. NOTE: Check the automatic transmission fluid level
before towing.
Towing Tips — Tow/Haul (If Equipped)
To reduce potential for automatic transmission overheat-
ing, turn the “TOW HAUL OD/OFF” feature ON when
driving in hilly areas or shift the transmission to Drive
position 2 on more severe grades.
Towing Tips — Electronic Speed Control (If
Equipped)
Don’t use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency. STARTING AND OPERATING 353
