American Petroleum Institute (API)
Approved Engine Oil
These symbols mean that the oil has been certified
by the API. The manufacturer only recommends API
trademark oils.
The API Starburst trademark certifies
0W-20, 0W-30 and 5W-30 engine oils.
The API Donut trademark certifies 0W-40
and 5W-40 engine oil.
For diesel engines, oils with a high ash content may
produce damaging deposits on cylinder head
valves and/or after-treatment system damage. A
maximum sulfated ash content of 1.00 mass % is
recommended for all oil used in the engine.
The same oil change interval is to be followed for
synthetic oil as for petroleum-based oil. Also,
synthetic oil must meet the same performance
specifications as petroleum oil.
Synthetic Engine Oils
Your engine was designed for synthetic engine oils,
only use synthetic API approved engine oils.
Synthetic engine oils which do not have both the
correct API trademark and the correct SAE viscosity
grade numbers should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against
the addition of any additives (other than leak
detection dyes) to the engine oil. Engine oil is an
engineered product and its performance may be
impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil
Filters
Care should be taken in disposing of used engine
oil and oil filters from your vehicle. Used oil and oil
filters, indiscriminately discarded, can present a
problem to the environment. Contact an
authorized dealer, service station or governmental
agency for advice on how and where used oil and
oil filters can be safely discarded in your area.
ENGINE OIL FILTER
The engine oil filter should be replaced with a new
filter at every engine oil change.
Engine Oil Filter Selection
A full-flow type disposable oil filter should be used
for replacement. The quality of replacement filters varies considerably. Only high quality Mopar®
certified filters should be used.
ENGINE AIR CLEANER FILTER
For the proper maintenance intervals
Úpage 329.
NOTE:Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality filters
should be used to ensure most efficient service.
Mopar® engine air cleaner filters are a high quality
filter and are recommended.
CAUTION!
Do not use chemical flushes in your engine oil as
the chemicals can damage your engine. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in the
case of engine backfire. Do not remove the air
induction system (air cleaner, hoses, etc.) unless
such removal is necessary for repair or mainte -
nance. Make sure that no one is near the engine
compartment before starting the vehicle with
the air induction system (air cleaner, hoses, etc.)
removed. Failure to do so can result in serious
personal injury.

AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
Refrigerant Recovery And Recycling
R-134a — If Equipped
R-134a Air Conditioning Refrigerant is a Hydrofluo -
rocarbon (HFC) that is an ozone-friendly
substance. The manufacturer recommends that
air conditioning service be performed by an
authorized dealer or other service facilities using
recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil and refrigerants.
Refrigerant Recovery And Recycling
R-1234yf — If Equipped
R-1234yf Air Conditioning Refrigerant is a Hydroflu -
oroolefin (HFO) that is endorsed by the
Environmental Protection Agency and is an
ozone-friendly substance with a low
global-warming potential. The manufacturer
recommends that air conditioning service be
performed by an authorized dealer using recovery
and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil, and refrigerants.

WARNING!

Use only refrigerants and compressor lubri
-
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty Infor -
mation Book, for further warranty information.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring lines
to be disconnected should be done by an expe -
rienced technician.

CAUTION!

Do not use chemical flushes in your air condition -
ing system as the chemicals can damage your air
conditioning components. Such damage is not
covered by the New Vehicle Limited Warranty.

PRIMING IF THE ENGINE HAS RUN OUT
O
F FUEL

1. Add a substantial amount of fuel to the tank,
approximately 2 to 5 gal (8L to 19L).

2. Three priming cycles must be completed. Turn ignition to the RUN position and wait approxi -
mately 30 seconds. This will activate the in tank
fuel pump. Turn the ignition switch to the off
position, and leave off for at least 30 seconds.
Repeat this procedure three times before
cranking the engine.
3. Start the engine using the “Normal Starting”
procedure Ú page 108.
4. Once the engine starts, allow the engine to idle for a minimum of 30 seconds.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.
NOTE:
A maximum blend of 5% biodiesel, meeting
ASTM specification D-975 may be used with
your Cummins® diesel engine.
A maximum blend of 20% biodiesel, meeting
ASTM specification D-7467 may be used with
your Cummins® diesel engine.
Use of biodiesel mixture in excess of 20% can
negatively impact the fuel filter's ability to sepa -
rate water from the fuel, resulting in high pres -
sure fuel system corrosion or damage.
Ethanol blends are not recommended or
approved for use with your Cummins® diesel
engine.
In addition, commercially available fuel addi -
tives are not necessary for the proper operation
of your Cummins® diesel engine.

The Cummins® diesel engine meets all
Environmental Protection Agency (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 system. The engine and exhaust
after-treatment system work together to achieve
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.
CAUTION!
Do not engage the starter motor for more than
15 seconds at a time. Allow two minutes
between the cranking intervals.
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.
