2012 Ram 5500 Chassis Cab Diesel Supplement

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)
•Brake pedal must not be applied
•Vehicle engine 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 upfitter-provided on/off
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 turn the upfitter-provided on/off switch to the
OFF position.
The torque converter lockup clutch will automatically
engage at engine speeds above 1,200 RPM (engine speed)
in PTO stationary mode. Once engaged, the lockup clutch
will remain on and not disengage until the engine speed
is below 1,000 RPM. Lockup clutch engagement is desir-
able for certain types of PTO applications (AS68RC
Six-Speed Automatic Transmission Only).

STARTING AND OPERATING 79

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:If you desire a single PTO speed, your vehicle
must be wired to use a remote PTO switch. For instruc-
tions on programming the SET speed, refer to the
LEARNING SET SPEED section of the Body Builder’s
Guide which can be found at www.ramtrucks.com.
Mobile Mode
To operate the PTO in this mode the vehicle must meet
the following conditions:
•Authorized dealer-selected “mobile” mode activated
via authorized dealer proprietary service tool
•Upfitter-provided (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
•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
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 upfitter-provided PTO
80 STARTING AND OPERATING

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 opera-
tion” simply turn the upfitter-provided on/off switch to
the OFF position.

to PTO and pump requirements and additional vehicle
information (wiring schematics, preset idle values, en-
gine speed limits, and vehicle hardware and software
requirements) please refer to the Body Builders Guide by
accessing www.ramtrucks.com and choosing the appro-
priate links.

ENGINE RUNAWAY
WARNING!
In case of engine runaway due to flammable fumes
from gasoline spills or turbocharger oil leaks being
sucked into the engine, do the following to help
avoid personal injury and/or vehicle damage:
1. Turn the ignition switch to the OFF position.
2. Using a CO
2or dry chemical type fire extin-
guisher, direct the spray from the fire extinguisher
into the grille on the passenger side so that the spray
enters the engine air intake.

STARTING AND OPERATING 81

WARNING! (Continued)
The inlet for the engine air intake is located behind
the passenger side headlamp and receives air
through the grille.
FUEL REQUIREMENTS
Use good quality diesel fuel from a reputable supplier in
your vehicle. Federal law requires that you must fuel this
vehicle with Ultra Low Sulfur Highway Diesel fuel (15
ppm Sulfur maximum) and prohibits the use of Low
Sulfur Highway Diesel fuel (500 ppm Sulfur maximum)
to avoid damage to the emissions control system. For
most year-round service, No. 2 diesel fuel meeting ASTM
specification D-975 Grade S15 will provide good perfor-
mance. If the vehicle is exposed to extreme cold (below
20°F or -7°C), or is required to operate at colder-than-
normal conditions for prolonged periods, use climatized
No. 2 diesel fuel or dilute the No. 2 diesel fuel with 50%No. 1 diesel fuel. This will provide better protection from
fuel gelling or wax-plugging of the fuel filters.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and hazardous or explosive when mixed with diesel
fuel.
Diesel fuel is seldom completely free of water. To prevent
fuel system trouble, drain the accumulated water from
the fuel/water separator using the fuel/water separator
drain provided. If you buy good quality fuel and follow
the cold weather advice above, fuel conditioners should
not be required in your vehicle. If available in your area,
a high cetane “premium” diesel fuel may offer improved
cold-starting and warm-up performance.
82 STARTING AND OPERATING

Fuel Specifications
The Cumminsdiesel engine has been developed to take
advantage of the high energy content and generally
lower cost No. 2 Ultra Low Sulfur diesel fuel or No. 2
Ultra Low Sulfur climatized diesel fuels. Experience has
shown that it also operates on No. 1 Ultra Low Sulfur
diesel fuels or other fuels within specification.
NOTE:
•A maximum blend of 5% biodiesel meeting ASTM
specification D-6751 may be used with your Cum-
mins diesel engine.
•In addition, commercially available fuel additives are
not necessary for the proper operation of your Cum-
minsdiesel engine.
•No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F or -23°C) exist.
ADDING FUEL
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
•Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
•Make sure that the fuel filler cap is tightened each time
the vehicle is refueled.

STARTING AND OPERATING 83

WARNING!
A fire may result if fuel is pumped into a portable
container that is on a truck bed. You could be burned.
Always place fuel containers on the ground while
filling.
Fuel Filler Cap
If the fuel filler cap is lost or damaged, be sure the
replacement cap is for use with this vehicle.
CAUTION!
Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler tube cap. A poorly fitting cap could let impuri-
ties into the fuel system.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the fuel filler cap is removed or
the tank filled.
•Never add fuel to the vehicle when the engine is
running.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage – Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of “microbes.” These
84 STARTING AND OPERATING

microbes form “slime” that will clog fuel filters and lines.
Drain condensation from the supply tank and change the
line filter on a regular basis.
NOTE:When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
If the vehicle will not start, refer to “Maintenance
Procedures/Priming If The Engine Has Run Out Of Fuel”
in “Maintaining Your Vehicle” for further information.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in tempera-
tures between 10° to 90°F (-12° to 32°C), it will last a
minimum of one year.
DEF is subject to freezing at the lowest temperatures. For
example, DEF may freeze at temperatures at or below
12° F (-11° C). The system has been designed to operate in
this environment.
NOTE: When working with DEF, it is important to
know that:
•Any containers or parts that come into contact with
DEF must be DEF compatible (plastic or stainless
steel). Copper, brass, aluminum, iron or non-stainless
steel should be avoided as they are subject to corrosion
by DEF.
•If DEF is spilled, it should be wiped up completely

STARTING AND OPERATING 85

Adding Diesel Exhaust Fluid – Chassis Cab Only
The DEF gauge (located on the EVIC display) will
display the level of DEF remaining in the tank. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
•When the DEF gauge reads 75%, add approximately
2 gallons (7.5 Liters) to fill the DEF tank.
•When the DEF gauge reads 50%, add approximately
4 gallons (15 Liters) to fill the DEF tank.
•When the DEF gauge reads 25%, add approximately
6 gallons (23 Liters) to fill the DEF tank.
NOTE: Driving conditions (altitude, vehicle speed,
load, etc.) will effect the amount of DEF that is used in
your vehicle.
DEF Fill Procedure
NOTE: Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for the correct fluid type.
1. Remove cap from DEF tank (located on drivers side of
the vehicle).
