NOTE:
•If you accidentally fill the fuel tank with gasoline on
your diesel vehicle, do not start the engine. Damage to
the engine and fuel system could occur. Please call
your authorized dealer for service.
• A maximum blend of 5% biodiesel meeting ASTM
specification D-975 may be used with your diesel
engine without any adjustments to regular service
schedules.
• Commercially available fuel additives are not neces-
sary for the proper operation of your diesel engine.
• No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F or -23°C) exist.Biodiesel Fuel Requirements
A maximum blend of 5% biodiesel meeting ASTM speci-
fication D975 is recommended for use with your diesel
engine. If frequent operation with Biodiesel blends that
are between 6% and 20% (B6–B20) is desired, the main-
tenance schedule is subject to shorter intervals.
The oil and filter change along with fuel filter replace-
ment is subject to shorter intervals when operating your
engine on biodiesel greater than 5%. Do not use biodiesel
greater than 20%.
For regular use of biodiesel blends between 6% and 20%
(B6–B20) it is important that you understand and comply
with these requirements. Refer to the “Maintenance
Chart” in the “Maintenance Schedules” section for fur-
ther direction.

CAUTION!
Failure to comply with Oil Change requirements for
vehicles operating on biodiesel blends between 6%
and 20% (B6–B20) will result in premature engine
wear. Such wear is not covered by the New Vehicle
Limited Warranty.
Biodiesel is a fuel produced from renewable resources
typically derived from animal fat, rapeseed oil (Rapeseed
Methyl Ester (RME) base), or soybean oil (Soy Methyl
Ester (SME or SOME) base).
Biodiesel fuel has inherent limitations which require that
you understand and adhere to the following requirements
if you use blends of Biodiesel between 6% and 20%
(B6–B20). There are no unique restrictions for the use of B5.
CAUTION!
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.
Biodiesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient tem-
peratures, which may pose problems for both storage and
operation. Precautions can be necessary at low ambient
temperatures, such as storing the fuel in a heated build-
ing or a heated storage tank, or using cold temperature
additives.

Biodiesel Fuel Filter Change Intervals
The use of biodiesel requires intervals shorter than the
outlined 30,000 miles (48 280 km) and must not exceed
the suggested schedule. When operating on biodiesel
between 6% and 20%, fuel filter replacement intervals
must not exceed 20,000 Miles (40 233 km).
NOTE:Under no circumstances should oil change inter-
vals exceed 8,000 miles (12 875 km) or 6 months, if
regular operation occurs with 6% - 20% biodiesel blends.
Under no circumstances should fuel filter intervals ex-
ceed 20,000 miles (40 233 km), if regular operation occurs
with 6% - 20% biodiesel blends. Failure to comply with
these Oil Change and fuel filter requirements for vehicles
operating on biodiesel blends up to B20 may result in
premature engine wear. Such wear is not covered by the
New Vehicle Limited Warranty. The engine may suffer
severe damage if operated with concentrations of bio-
diesel higher than 20%.
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic Re-
duction system to meet the very stringent diesel emis-
sions standards required by the Environmental Protec-
tion Agency.
The purpose of the SCR system is to reduce levels of NOx
(oxides of nitrogen emitted from engines) that are harm-
ful to our health and the environment to a near-zero level.
Small quantities of Diesel Exhaust Fluid (DEF) is injected
into the exhaust upstream of a catalyst where, when
vaporized, it converts smog-forming nitrogen oxides
(NOx) into harmless nitrogen (N2) and water vapor
(H2O), two natural components of the air we breathe.
You can operate with the comfort that your vehicle is
contributing to a cleaner, healthier world environment
for this and generations to come.

Engine Oil
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer recom-
mends engine oils that meet the requirements of FCA
Material Standard MS-11106, and that are approved to
ACEA C3.
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals. The best time to check
the oil level is before starting the engine after it has been
parked overnight. When checking oil after operating the
engine, first ensure the engine is at full operating tem-
perature, then wait for five minutes after engine shut-
down to check the oil.
1 — MAX Mark
2—MINMark
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil
only when the level on the dipstick is below the “MIN”

mark. The total capacity from the MIN mark to the MAX
mark is 1.3 qts (1.2 L).
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
NOTE: It is possible for your oil level to be slightly
higher than a previous check. This would be due to diesel
fuel that may temporarily be in the crankcase due to
operation of the diesel particulate filter regeneration
strategy. This fuel will evaporate out under normal
operation.
Never operate the engine with oil level below the “MIN”
mark or above the upper “MAX” mark.
Change Engine Oil
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Engine Oil Viscosity (SAE Grade)
CAUTION!
Your vehicle is equipped with an advanced technol-
ogy Diesel Engine and an emission device designed
to limit Diesel Particulate Emissions from being
released into the atmosphere. The durability of your
engine and life expectancy of this diesel particulate
filter emission device is highly dependent on the use
of the correct engine oil.
Only use ACEA C3 SAE 5W-30 Synthetic Low Ash engine
oil meeting FCA Material Standard MS-11106 or Pennzoil
Ultra Euro L full synthetic 5W-30 motor oil, which is

recommended for all operating temperatures. This en-
gine oil improves low temperature starting and vehicle
fuel economy.
Materials Added To Engine Oil
The manufacturer strongly recommends against the ad-
dition 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 addi-
tives.
Engine Oil Filter
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information. The
engine oil filter should be changed at every engine oil
change.
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 your 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 Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
CAUTION!
All air entering the engine intake must be filtered.
The abrasive particles in unfiltered air will cause
rapid wear to engine components.
