{Sales Code EXG) only.
DISCUSSION:
The affected vehicles are equipped with diesel engines that use a Selective Catalytic
Reduction (SCR) exhaust emissions aftertreatment system . This technology is used to
reduce the Nitrogen Oxides (NOx) emissions of the engine so that it meets current U.S.
EPA and California exhaust emission requirements . In order to function properly and
ensure the vehicle meets applicable emission standards, the SCR system injects Diesel
Exhaust Fluid (DEF) into the exhaust upstream of the SCR catalyst. The DEF reacts with
the exhaust gas inside the catalyst to convert NOx to harmless gasses prior to release into
the atmosphere .

Since DEF is consumed during operation of the vehicle , the DEF tank must be refilled
periodically as outlined in the Owners Manual Diesel Supplement. The DEF filler cap is
clearly marked "Diesel Exhaust Fluid". On Cab Chassis vehicles, the cap is located behind
the cab on the driver's side of the truck . On Pickup trucks, the cap is located behind the
fuel fill door. The tank is pre-filled with approximately 3 gallons of DEF from the
manufacturing assembly plant. This factory fill should be adequate to perform the vehicle's
Pre-Delivery Inspection and other in-dealership operations.
These diesel vehicles are equipped with an Electronic Vehicle Information Center (EVIC)
that will provide the driver with warning messages displayed by the EVIC and audible
chimes informing the driver when it is necessary to refill the DEF tank. Please refer to the
applicable Owner's Manual Diesel Supplement for complete aftertreatment warning
message details .
**The driver will be notified when the level of DEF drops below approximately 2.5 gallons.
The first level warning displays the message "5 MPH Max Speed in XXXX mi DEF Low
Refill Soon". The mileage counter will then begin to countdown to 0 as the vehicle is
driven . The message "5 MPH Max Speed on Restart, Long Idle, or Refuel" will then be
displayed followed by the message, "5 MPH Max Speed Refill DEF." At this point, the
vehicle will be reduced to a maximum of 5 mph until the DEF tank is refilled. The
Powertrain Control Module (PCM) may also set a Diagnostic Trouble Code (DTC) P203F (Diesel Exhaust Fluid) Reductant Level Too Low.**
NOTE: **A minimum of 2.5 gallons of DEF will need to be added in order for the
system to reset and clear out the message.**
As indicated on the "New Vehicle Preparation Form," dealers are requested to fill the DEF
tank just prior to delivering the vehicle to the owner. Labor Operation 25-08-01-40 can be
used to reimburse dealers for this DEF fill. This Labor Operation can only be used prior to
resale delivery and is not intended to be used for any warranty repair.
NOTE: Do not prematurely fill the DEF tank. DEF has a limited shelf life based on
ambient temperatures and exposure to sunlight. Vehicles that are exposed to
high temperatures for lengths of time may have their DEF urea concentration
degrade to the point that the DEF will become less effective at reducing NOx
levels in the SCR catalyst. If this occurs, the engine control system may
illuminate the Malfunction Indicator Lamp (MIL) and set related Diagnostic
Trouble Codes (OTC). Refer to the following chart to get a better
understanding of DEF shelf life.
The following chart provides the approximate shelf life of DEF versus temperature.

It is recommended that dealers store DEF in a location that minimizes this degradation.
If it is suspected that the urea concentration level has decreased too low, DEF can be
tested using a Refractometer. OTC DEF/UREA Refractometer (16-5025) is available
through Pentastar Service Equipment (PSE). DEF urea concentration should be at 32 .5%.
The DEF tank has been designed with an air space that accommodates the expansion of
DEF. Never 'top-off' the DEF tank after a normal fill , as that will allow DEF to fill the
expansion space, which can cause damage to the tank.
DEF is subject to freezing at the lowest temperatures . For example, DEF may freeze at
temperatures at or below 12° F (-11 ° C). The system has been designed to operate in this
environment.
Containers, pumps or plumbing containing iron , non-stainless steel, aluminum or brass will
rapidly corrode if used to store or transfer DEF. This corrosion can result in plugging of the
onboard DEF filter, or other emission system damage.
If DEF is spilled , it should be cleaned up with mild soap and water to avoid corrosion or
damage to components and finished surfaces.
DEF can crystallize when exposed to air. However, the crystals should re-dissolve when
reintroduced to fresh DEF . Crystallization may be noticed around the DEF filler opening
and is normal .
Please refer to the Service Information and/or the Owner's Manual for additional
information .
NOTE: Improper, diluted, or contaminated DEF may lead to MIL illumination and
reduced speed conditions, so it is important to use 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.
