WHAT IS THE DIESEL
PARTICULATE FILTER
The diesel particulate filter is part of yourvehicle's emissions system and filtersharmful diesel particulates from theexhaust gas.
HOW DOES THE DIESEL
PARTICULATE FILTER WORK
The diesel particulate filter reducesemissions by trapping exhaust particlesbefore they reach the tailpipe. The systemmust periodically clean the exhaustparticles that gather inside the filter. Thisis carried out in three ways, passiveregeneration, active regeneration andmanual regeneration.
Passive Regeneration
In passive regeneration, the normalexhaust system temperature cleans thefilter by oxidizing the soot. Cleaning occursduring normal vehicle operating conditionsdue to driving patterns.
Active Regeneration
Once the diesel particulate filter is full,active regeneration raises the exhausttemperature to eliminate the particles.
When the engine control module detectsthat the diesel particulate filter is nearlyfull of particulates, and you are notoperating your vehicle in a manner to alloweffective regeneration, messages appearin the information display as a reminderfor you to drive your vehicle in order toclean the diesel particulate filter. If youdrive your vehicle in a manner to alloweffective regeneration, the informationdisplay shows a cleaning exhaust filtermessage.
DIESEL PARTICULATE FILTER
PRECAUTIONS
WARNING: Do not park or idle yourvehicle over dry leaves, dry grass or othercombustible materials. The regenerationprocess creates very high exhaust gastemperatures and the exhaust willradiate a considerable amount of heatduring and after regeneration and afteryou have switched the engine off. This isa potential fire hazard.
WARNING: When the ExhaustFilter Cleaning message appears in theinformation display, do not park nearflammable materials, vapors orstructures until filter cleaning iscomplete.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the diesel oxidationcatalytic converter or the dieselparticulate filter. The diesel oxidationcatalytic converter and the dieselparticulate filter heat up to very hightemperatures after only a short periodof engine operation and remain hot afteryou switch the engine off.
Note:Avoid running out of fuel.
Note: During regeneration at low speed orengine idle, you may smell a hot metallicodor and could notice a clicking metallicsound. This is due to high temperaturesreached during regeneration and is normal.
Note:Changes in the engine or exhaustsound may be heard during the regenerationprocess.

WHAT IS THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM
The selective catalytic reduction systemhelps reduce tailpipe emissions andrequires Diesel Exhaust Fluid (DEF) toconvert nitrogen oxides into nitrogen andwater.
HOW DOES THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM WORK
The selective catalytic reduction systeminjects diesel exhaust fluid into the exhaustsystem to enable correct selective catalyticreduction system function.
The usage of diesel exhaust fluid hasincreased from prior model years in orderto meet more stringent emissionsrequirements. The diesel exhaust fluidusage ranges from approximately 2-6%of fuel burned (100.00 gal (378.54 L) offuel requires approximately 2.00 gal(7.57 L)to 6.00 gal (22.71 L) of dieselexhaust fluid) depending on vehicle usage.Factors that influence diesel exhaust fluidusage may include:
•Payload/Towing
•Driving Style
•Altitude
•Humidity
•Temperature

PRECAUTIONS
WARNING: Keep diesel exhaustfluid out of reach of children. Avoidcontact with skin, eyes or clothing. Incase of contact with your eyes, flushimmediately with water and get promptmedical attention. In case of contactwith your skin, clean immediately withsoap and water. If you swallow anydiesel exhaust fluid, drink plenty ofwater, call a physician immediately.
WARNING: Only refill the dieselexhaust fluid tank in a well ventilatedarea. When you remove the dieselexhaust fluid tank filler cap or a dieselexhaust fluid container cap, ammoniavapors may escape. Ammonia vaporscan be irritating to skin, eyes and mucousmembranes. Inhaling ammonia vaporscan cause burning to the eyes, throat andnose and cause coughing and wateryeyes.
WARNING: Diesel exhaust fluidmust be refilled when low or replacedwhen contaminated or your vehiclespeed becomes limited to 50 mph(80 km/h). In these conditions, drive withcaution and refill diesel exhaust fluidimmediately. If the diesel exhaust fluidbecomes empty or contaminated andfluid is not replaced, your vehiclebecomes limited to engine idle only oncestopped. In these conditions, be cautiouswhere you stop your vehicle because youmay not be able to drive long distancesor maintain highway speeds until yourefill or replace the diesel exhaust fluid.

WARNING: Tampering with ordisabling the selective catalyticreduction system results in severevehicle performance limitation includingeventual speed limiting to 5 mph(8 km/h).
Note: Do not put diesel exhaust fluid in thefuel tank. Do not start the engine if anyamount of diesel exhaust fluid was addedto the diesel fuel tank as it will likely lead tofailure of the fuel pump and injectors andmay result in severe engine damage whichyour vehicle Warranty may not cover. Thediesel fuel tank must be completely drainedand cleaned prior to being refilled with cleandiesel fuel and starting the engine.
Selective catalytic reduction systems aresensitive to contamination of the dieselexhaust fluid. Maintaining the purity of thefluid is important to avoid systemmalfunctions. If you remove or drain thediesel exhaust fluid tank, do not use thesame fluid to refill the tank. The systemhas a sensor to monitor fluid quality.
Driving without refilling, replacingcontaminated diesel exhaust fluid, orhaving the selective catalytic reductionsystem repaired results in the followingactions as required by the California AirResources Board (CARB) and the U.S.Environmental Protection Agency (EPA):
•Within a preset distance to empty,speed is limited upon vehicle restart.Prior to this occurring a messageappears in the information display.
•Further vehicle operation withoutrefilling or replacing contaminateddiesel exhaust fluid causes the engineto enter an idle-only condition. Thisonly occurs upon vehicle refueling,vehicle idling in park for 1 hour, orengine shutdown for 10 minutes ormore and is indicated by a message inthe information display indicatingrequired actions to resume normaloperation. It is required to add aminimum of 1.0 gal (3.8 L) of dieselexhaust fluid to the tank to exit theidle-only condition, but your vehicle isstill in the speed-limiting mode untilyou refill the tank completely.
Note:For vehicle speed limiting or idle-onlycondition, normal vehicle operation resumeswhen you refill the diesel exhaust fluid tankor repair the contaminated system. If thesystem is contaminated or inoperative, haveyour vehicle checked as soon as possible.

GUIDELINES
•Diesel exhaust fluid is non-flammable,non-toxic, colorless and water-solubleliquid.
•In order for the system to operatecorrectly you must maintain the dieselexhaust fluid level.
•Do not overfill the diesel exhaust fluidtank.
•Diesel exhaust fluid is corrosive.
•Avoid spilling diesel exhaust fluid onpainted surfaces, carpeting or plasticcomponents. Immediately wipe awayany diesel exhaust fluid that has spilledwith a damp cloth and water. If it hasalready crystallized, use warm waterand a sponge.
•Do not store the diesel exhaust fluidbottle in your vehicle. If it leaks it couldcause damage to interior componentsor release an ammonia odor inside yourvehicle.
•Do not re-use the diesel exhaust fluidcontainer once it is emptied.
•Store diesel exhaust fluid out of directsunlight and in temperatures between23–68°F (-5–20°C).
•The system has a diesel exhaust fluidquality sensor. Dilution of dieselexhaust fluid or use of any other liquidin the selective catalytic reductionsystem leads to a diesel exhaust fluidsystem fault, eventually leading to thevehicle only operating in idle-onlymode.
•Do not dilute diesel exhaust fluid withwater or any other liquid.
