in the ON position, there may be a problem with your
water separator wiring or sensor. See your authorized
dealer for service.
Upon proper draining of the water from the fuel filter, the
“Water In Fuel Indicator Light” will remain illuminated for
approximately 10 seconds. If the water was drained while
the engine was running, the “Water In Fuel Indicator
Light” may remain on for approximately three minutes.
NOTE:Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately discarded,
can present a problem to the environment. Contact an
authorized dealer, service station, or government agency
for advice on recycling programs and for where used fluids
and filters can be properly disposed of in your area.
Drain the fuel/water separator filter when the “Water In
Fuel Indicator Light” is ON. Within 10 minutes of vehicle
shutdown, turn the filter drain valve (located on the
bottom of the filter housing) counterclockwise to drain
fuel/water, then turn the ignition switch to the ON posi-
tion, and allow any accumulated water to drain. Leave the
drain valve open until all water and contaminants have
been removed. When clean fuel is visible, close the drain
valve by turning it clockwise, and turn the ignition switch
to OFF. If more than two ounces or 60 milliliters of fuel have been
drained, follow the directions for “Priming If The Engine
Has Run Out Of Fuel.”
Underbody Mounted Fuel Filter Replacement
NOTE:
Using a fuel filter that does not meet the manufac-
turer’s filtration and water separating requirements can
severely impact fuel system life and reliability.
CAUTION!
• Diesel fuel will damage blacktop paving surfaces.
Drain the filter into an appropriate container.
• Do not prefill the fuel filter when installing a new
fuel filter. There is a possibility debris could be
introduced into the fuel filter during this action. It is
best to install the filter dry and allow the in-tank lift
pump to prime the fuel system.

•PTO must be correctly installed using the vehicle pro-
vided circuits.
The instrument cluster will display a PTO Onmessage for
five seconds if the above conditions are met. Otherwise, the
instrument cluster will display a message To Operate PTO
Shift To Park indicating what operator action should be
taken to engage the PTO mode.
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 operate the feature
using the cruise control switches, the customer must first
activate the PTO switch which will turn on the PTO. In
order to increase or decrease the engine idle speed, to
optimize the PTO function, the “RESUME/ACCEL” and
“DECEL” cruise switches can be used respectively. To
disengage PTO operation and return to “standard vehicle
operation” simply toggle the PTO switch to the OFF
position.
The torque converter clutch (TCC) will automatically en-
gage at engine speeds above 1,200 RPM (engine speed) in
PTO stationary mode. Once engaged, the TCC will remain
applied and will not disengage until the engine speed falls
below 1,000 RPM. TCC engagement is desirable for certain
types of PTO applications (Automatic Transmission Only). 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.
NOTE:
Single set speed can be programmed via the PTO
menu on the instrument cluster display. Further details are
available at the Ram Truck Bodybuilders web site located
at
rambodybuilder.com
Mobile Mode
To operate the PTO in this mode the vehicle must meet the
following conditions:
• Mobile mode is activated via the menu on the instru-
ment cluster display.
• (ON/OFF) switch has been activated.
• Vehicles with automatic transmission must be in PARK
or DRIVE.

STARTING AND OPERATING 155

•Parking brake must not be applied.
• Brake pedal must not be applied.
• No vehicle, brake or clutch switch faults present.
• Vehicle engine must be running.
• PTO must be correctly installed using the vehicle pro-
vided 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 accom-
plished by activating the upfitter-provided PTO on/off
switch. At this point, the customer may place the vehicle in
a forward or reverse gear and have PTO operation once the
vehicle begins to move. To disengage PTO operation and
return to “standard vehicle operation” simply toggle the
on/off switch to the OFF position.
NOTE: For application specific information with respect
to PTO and pump requirements and additional vehicle
information (wiring schematics, preset idle values, engine
speed limits, and vehicle hardware and software require-
ments) please refer to the Body Builders Guide by access-

ENGINE RUNAWAY
Diesel engine runaway is a rare condition affecting diesel
engines, where the engine consumes its own lubrication oil
and runs at higher and higher RPM until it overspeeds to
a point where it destroys itself due to either mechanical
failure or engine seizure through lack of lubrication.
WARNING!
In case of engine runaway due to flammable fumes
from fuel spills or turbocharger oil leaks being sucked
into the engine, do the following to help avoid per-
sonal injury and/or vehicle damage:
1. Turn the ignition switch to the OFF position.
2. Using a CO2 or dry chemical type fire extinguisher,
direct the spray from the fire extinguisher into the
grille on the passenger side so that the spray enters the
engine air intake.
The inlet for the engine air intake is located behind the
passenger side headlamp and receives air through the
grille.
156 STARTING AND OPERATING

2. Install the air cleaner cover onto the housing assemblylocating tabs.
3. Install screws to secure the air cleaner cover to the housing assembly.
Draining Fuel/Water Separator Filter
There are two fuel filter assemblies. One is located on the
driver’s side of the engine. The best access to this water
drain valve is from under the hood. The second one is on
the under body, located in front of the rear axle above the
drive shaft on pick-up models. The Chassis Cab models
second filter location is on the frame behind the front axle.
The best access to this water drain valve is from under the
vehicle.
CAUTION!
•Do not drain the fuel/water separator filter when the
engine is running.
• Diesel fuel will damage blacktop paving surfaces.
Drain the filter into an appropriate container.
If water is detected in the water separator while the engine
is running, or while the ignition switch is in the ON
position, the “Water In Fuel Indicator Light” will illumi-
nate and an audible chime will be heard five times. At this point you should stop the engine and drain the water from
both of the filters.
CAUTION!
If the “Water In Fuel Indicator Light” remains on, DO
NOT START the engine before you drain water from
the fuel filters to avoid engine damage.
If the “Water In Fuel Indicator Light” comes on and a single
chime is heard while you are driving, or with the ignition
switch in the ON position, there may be a problem with
your water separator wiring or sensor. See your authorized
dealer for service.
Upon proper draining of the water from both fuel filters,
the “Water In Fuel Indicator Light” will remain illuminated
for approximately 10 seconds. If the water was drained
while the engine was running, the “Water In Fuel Indicator
Light” may remain on for approximately three minutes.
NOTE: Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately discarded,
can present a problem to the environment. Contact an
authorized dealer, service station, or government agency
for advice on recycling programs and for where used fluids
and filters can be properly disposed of in your area.

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made directly
to the battery and fused as close to the battery as possible.
The negative power connection should be made to body
sheet metal adjacent to the negative battery connection.
This connection should not be fused.
Antennas for two-way radios should be mounted on the
roof or the rear area of the vehicle. Care should be used
in mounting antennas with magnet bases. Magnets may
affect the accuracy or operation of the compass on
vehicles so equipped.The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
