following requirements if you use blends of biodiesel
greater then 5% but not greater than 20% (B6-B20). There
are no unique restrictions for the use of B5. Use of blends
greater than 20% is not approved. Use of blends greater
than 20% can result in engine damage. Such damage is not
covered by the New Vehicle Limited Warranty.
Fuel Quality — Must Comply With ASTM
Standards
The quality of biodiesel fuel may vary widely. Only fuel
produced by a BQ9000 supplier to the following specifica-
tions may be blended to meet biodiesel blend (B6–B20) fuel
meeting ASTM specification D-7467:
•Pretrodiesel fuel meeting ASTM specification D-975 and
biodiesel fuel (B100) meeting ASTM specification
D-6751.
Fuel Oxidation Stability — Must Use Fuel Within
Six Months Of Manufacture
Biodiesel fuel has poor oxidation stability which can result
in long term storage problems. Fuel produced to approved
ASTM standards, if stored properly, provides for protec-
tion against fuel oxidation for up to six months.
Fuel Water Separation — Must Use MOPAR/
Cummins Approved Fuel Filter Elements
You must use MOPAR/Cummins approved fuel filter
elements in both your engine mounted filter and frame
mounted filter.
Biodiesel fuel has a natural affinity to water and water
accelerates microbial growth. Your MOPAR/Cummins fil-
tration system is designed to provide adequate fuel water
separation capabilities.
Bio-Diesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient tempera-
tures, which may pose problems for both storage and opera-
tion. Precautions can be necessary at low ambient tempera-
tures, such as storing the fuel in a heated building or a heated
storage tank, or using cold temperature additives.
Fuel In Oil Dilution — Must Adhere To Required
Oil Change Interval
Fuel dilution of lubricating oil has been observed with the
use of biodiesel fuel. Fuel in oil must not exceed 5%. To
ensure this limit is met your oil change interval must be
maintained to the following schedule:
5
STARTING AND OPERATING 159

•Ram PickUp 2500/3500 Only — 15,000 Miles*
• Ram 3500/4500/5500 Chassis Cab — 12,500 Miles*
(*unless otherwise notified with a oil service message)
CAUTION!
•Under no circumstances should oil change intervals
exceed 15,000 miles (24 000 km) pickup or 12,500 miles
(20 000 km) chassis cab if operation occurs with greater
than 5% biodiesel blends. Oil change intervals should
not exceed 6 months in either case. Failure to comply
with these Oil Change requirements for vehicles op-
erating on biodiesel blends up to B20 may result in
premature engine wear. Such wear is not covered by
the New Vehicle Limited Warranty.
• B20 Biodiesel capable: The engine may suffer severe
damage if operated with concentrations of Biodiesel
higher than 20%.

160 STARTING AND OPERATING

•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.
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 system
could result from using an improper fuel tank filler
tube cap. A poorly fitting cap could let impurities 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 maintenance 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 microbes
form “slime” that will clog the fuel filtration system 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.

Priming If The Engine Has Run Out Of Fuel
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.
1. Add a substantial amount of fuel to the tank, approxi- mately 2 to 5 gal (8L to 19L).
2. Turn ignition switch to the start position to engage starter for one second, return ignition switch to run
position. This will activate in tank fuel pump for ap-
proximately 15 seconds. Repeat this process twice.
3. Start the engine using the “Normal Starting” procedure. Refer to “Starting Procedures” in “Starting and Operat-
ing” for further information.
CAUTION!
Do not engage the starter motor for more than 15
seconds at a time. Allow two minutes between the
cranking intervals.
NOTE: The engine may run rough until the air is forced
from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel blending agent.
They can be unstable under certain conditions and be
hazardous or explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gasoline, the use
of these fuels can cause damage to the fuel system.
NOTE:
• A maximum blend of 5% biodiesel, meeting ASTM
specification D-975 may be used with your Cummins
diesel engine. (Chassis Cab models not configured with
B20 capability.)
188 MAINTAINING YOUR VEHICLE

•A maximum blend of 20% biodiesel, meeting ASTM
specification D-7467 may be used with your Cummins
diesel engine. (Pickup models and Chassis Cab models
configured with B20 capability.)
• Use of biodiesel mixture in excess of 20% can negatively
impact the fuel filter’s ability to separate water from the
fuel, resulting in high pressure fuel system corrosion or
damage.
• Ethanol blends are not recommended or approved for
use with your Cummins diesel engine.
• In addition, commercially available fuel additives are
not necessary for the proper operation of your Cummins
diesel engine.
Intervention Regeneration Strategy — Message
Process Flow
The Cummins diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in one of the
lowest emitting diesel engines ever produced.
To achieve these emissions standards, your vehicle is
equipped with a state-of-the-art engine and exhaust sys-
tem. The engine and exhaust after-treatment system work
together to achieve the EPA Heavy Duty Diesel Engine Emissions Standards. These systems are seamlessly inte-
grated into your vehicle and managed by the Cummins
Powertrain Control Module (PCM). The PCM manages
engine combustion to allow the exhaust system’s catalyst
to trap and burn Particulate Matter (PM) pollutants, with
no input or interaction on your part.
If the engine is allowed to idle or the truck is driven on low
engine speed drive cycles for more than 2 hours, the
system will automatically enter an emissions operating
mode that will increase the engine idle speed to 900 RPM
(1050 RPM for Chassis Cab). While in this mode, which is
designed to help maintain the diesel particulate filter, the
engine idle speed will return to normal when the brake
pedal is applied. A small change in engine tone or a slight
change in engine performance while accelerating may also
be noticeable at speeds below 20 mph (32 kmh). This
operating mode may last for up to an hour of idle time, or
around 20 minutes of driving time.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your truck or engine.
Refer to “Instrument Cluster Display” in “Understanding
Your Instrument Panel” for further information.

MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned below the radiator and
the air conditioner condenser. Air enters the engine
through the air cleaner and passes through the turbo-
charger, where it is pressurized. This pressurized air rap-
idly reaches high temperature. The air is then directed
through a hose to the charge air cooler and through another
hose to the intake manifold of the engine. The air entering the engine has been cooled by about 50° to 100°F (10° to
38°C). This cooling process enables more efficient burning
of fuel resulting in fewer emissions.
To guarantee optimum performance of the system, keep
the surfaces of the charge air cooler, condenser and radiator
clean and free of debris. Periodically check the hoses
leading to and from the charge air cooler for cracks or loose
clamps resulting in loss of pressure and reduced engine
performance.
Brake System
Brake Master Cylinder — Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service, or immediately
if the “Brake System Warning Light” indicates system
failure.
The brake master cylinder has a translucent plastic reser-
voir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
full mark because leakage may occur at the cap.7
