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-6751 may be used with your Cum-
mins diesel engine. Use of biodiesel mixture in excess
of 5% 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 Cum-
minsdiesel engine.
Intervention Regeneration Strategy – EVIC
Message Process Flow
The Cummins diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in the low-
est emitting diesel engine ever produced.
To achieve these emissions standards, your vehicle is
equipped with a state-of-the-art engine and exhaust
system. The engine and exhaust after-treatment system
work together to achieve the EPA Heavy Duty Diesel
Engine Emissions Standards. These systems are seam-
lessly integrated into your vehicle and managed by the
Cummins Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust sys-
tem’s catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your truck or engine.

•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 cooling performance, poor gas
mileage, and increased emissions.
Charge Air Cooler – Inter-Cooler
The charge air cooler is positioned between 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
rapidly 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 immedi-
ately if the “Brake System Warning Light” indicates
system failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” mark and an “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.

Fuel Selection Use good quality diesel fuel from a reputable supplier in your vehicle.
Federal law requires that you must fuel this vehicle with Ultra Low Sul-
fur 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 performance. 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. This vehicle is fully
compatible with biodiesel blends up to 5% biodiesel meeting ASTM
specification D-975.
Diesel Exhaust Fluid – Chassis Cab
Only MOPAR
Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that
has been API Certified to the ISO 22241 standard. Use of fluids not API
Certified to ISO 22241 may result in system damage.

MAINTENANCE SCHEDULE
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
•Check the engine oil level at least 30 minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
Once a Month
•Inspect the batteries, and clean and tighten the termi-
nals as required.
•Check the fluid levels of the coolant reservoir, brake
master cylinder, and transmission and transfer case (if
equipped), add as needed.
At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Check the automatic transmission fluid level (if
equipped).
•Check the manual transmission fluid level (if
equipped).
•Check the coolant level, hoses, and clamps.
•Lubricate outer tie rod ends.
Inspection and service should also be performed anytime
a malfunction is observed or suspected. Retain all re-
ceipts.
