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.

REQUIREMENTS
Only use diesel exhaust fluid that iscertified by the American PetroleumInstitute (API).
You can purchase diesel exhaust fluid atan authorized dealer, or contact roadsideassistance for help in finding a retailer thatsells diesel exhaust fluid.
Note:Non-certified diesel exhaust fluid usecan cause damage that your Warranty maynot cover
SELECTIVE CATALYTIC
REDUCTION SYSTEM
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.

WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of yourvehicle's emissions system and filtersharmful pollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
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 catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a shortperiod of engine operation and stays hotafter the engine is switched off.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
To avoid damaging the catalytic converter:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 422).
•Use the correct fuel. See Fuel andRefueling (page 214).
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Do not make any unauthorizedchanges to your vehicle or engine. By law,vehicle owners and anyone whomanufactures, repairs, or services a fleet ofvehicles are not permitted to intentionallyremove an emission control device orprevent it from working.

POWER TAKE-OFF (IF EQUIPPED)
HOW DOES THE POWER TAKE-OFF WORK
Auxiliary equipment called power take-off,or PTO, is often added to the engine ortransmission to operate utility equipment.Examples include a wheel-lift for towtrucks, cranes, tools for construction or tireservice, and pumping fluids. PTOapplications draw auxiliary horsepowerfrom the powertrain, often while thevehicle is stationary. In this condition, thereis limited cooling air flow through theradiator and around the vehicle thatnormally occurs when a vehicle is moving.The aftermarket PTO system installer,having the most knowledge of the finalapplication, is responsible for determiningwhether additional chassis heat protectionor powertrain cooling is required, andalerting the user to the safe and properoperation.
Note:Use of auxiliary equipment thatexceeds the maximum Power Take-Off(PTO) load specified in our Truck BodyBuilders Layout Book can adversely affectthe performance of the powertrain system.Refer to the Body Builders Layout Book forinstructions about the appropriateinstallation of additional equipment.
