ENGINE OIL — GAS ENGINE
Engine Oil Selection — Gasoline Engine
Use only the manufacturer's recommended fluids
Úpage 473.
NOTE:Hemi engines (5.7L) at times can tick right after
startup and then quiet down after approximately
30 seconds. This is normal and will not harm the
engine. This characteristic can be caused by short
drive cycles. For example, if the vehicle is started
then shut off after driving a short distance. Upon
restarting, you may experience a ticking sound.
Other causes could be if the vehicle is unused for
an extended period of time, incorrect oil, extended
oil changes or extended idling. If the engine
continues to tick or if the Malfunction Indicator
Light (MIL) comes on, see the nearest authorized
dealer.
Engine Oil Selection — Diesel Engine
Use only the manufacturer's recommended fluids
Úpage 473.
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.
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.
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.

Engine Air Cleaner Filter Installation
NOTE:Inspect and clean the housing if dirt or debris is
present before replacing the engine air cleaner
filter.

1. Install the engine air cleaner filter into the housing assembly with the engine air cleaner
filter inspection surface facing downward.

2. Install the engine air cleaner filter cover onto the housing assembly.
3. Tighten the fasteners (six) on the engine air cleaner filter assembly.
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
maintenance. 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.

G/T AIR FILTER MAINTENANCE
Clean Engine Air Filter
The scheduled air filter cleaning interval is 30,
000 miles (48,280 km), or if in a dusty
environment the engine air filter should be
checked periodically to ensure optimal air flow.

1. Spray the air filter with the recommended
Mopar® air filter cleaner or apply mild
dishwashing detergent and water and let sit
for at least 10 minutes to loosen dir before
rinsing.

NOTE:Never use strong detergents, high pressure, or
gasoline on the air filter.
2. Rinse the air filter with cool low-pressure water applied from the inside (clean side) out in
order to flush the dirt out of the filter. Continue
to rinse the filter until all traces of the cleaner
have been removed.
NOTE:It may be necessary to repeat steps 1 and 2 if the
air filter is not completely clean.
3. After rinsing the air filter, gently shake off the excess water and allow air filter to dry
naturally.
NOTE:Do not use forced air pressure as it may damage
the filtering capabilities of the filter’s microfibers
and also void its warranty.
DRAINING FUEL/WATER SEPARATOR
F
ILTER — DIESEL ENGINE
The fuel/water separator filter housing is located
inside the frame rail, behind the left front wheel.
The best access to this water drain valve is from
under the vehicle.
If water is detected in the water separator while the
engine is running, or while the ignition switch is in
the ON/RUN position, the Water In Fuel Indicator
Light will illuminate and an audible chime will be
heard. At this point, you should stop the engine
and drain the water from the filter housing.
Fuel Filter Assembly

If the Water In Fuel Indicator Light comes on and a
single chime is heard while you are driving, or with
the ignition in the ON position, there may be a
problem with your water separator wiring or
sensor. See an authorized dealer for service.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running.
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appropriate
container.
1 — Water In Fuel Drain Valve
CAUTION!
If the Water In Fuel Indicator Light remains on,
DO NOT START the engine before you drain water
from the fuel filter to avoid engine damage.

6. Remove the used filter cartridge from the housing and dispose of it according to your
local regulations.
7. Wipe the sealing surfaces of the lid and housing clean.
8. Install a new o-ring into the ring groove on the filter housing and lubricate with clean engine
oil.
PRIMING IF THE ENGINE HAS RUN OUT
O
F FUEL — DIESEL ENGINE

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

2. Press ignition switch twice without your foot on brake to put vehicle in ON/RUN position. This
will activate the in tank fuel pump for approxi -
mately 30 seconds. Repeat this process twice. 3. Start the engine using the “Normal Starting”
procedure Ú page 144.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.
NOTE:
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.
In addition, commercially available fuel addi -
tives are not necessary for the proper operation
of your diesel engine.
For extreme cold conditions, "Mopar® Premium
Diesel Fuel Treatment" is recommended to
assist with cold starting.
INTERVENTION REGENERATION

TRATEGY — MESSAGE PROCESS FLOW
(D
IESEL ENGINE)
This engine meets all required diesel engine
emissions standards. To achieve these emissions
standards, your vehicle is equipped with a
state-of-the-art engine and exhaust system. These
systems are seamlessly integrated into your
vehicle and managed by the 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.
Additionally, your vehicle has the ability to alert you
to additional maintenance required on your vehicle
or engine Ú page 114.
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!
The starter motor will engage for approximately
30 seconds at a time. Allow two minutes
between 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.
