For best overall vehicle and engineperformance, premium fuel with an octanerating of 91 or higher is recommended. Theperformance gained by using premium fuelis most noticeable in hot weather as wellas other conditions, for example whentowing a trailer. See Towing a Trailer(page 365).
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contactan authorized dealer to prevent any enginedamage.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimalvehicle and engine performance.
For additional information, visitwww.toptiergas.com.
Note:Use of any fuel for which the vehiclewas not designed can impair the emissioncontrol system, cause loss of vehicleperformance, and cause damage to theengine which may not be covered by thevehicle Warranty.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 fuel.
•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel, using leaded fuel isprohibited by law.
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl, which is amanganese-based fuel additive, will impairengine performance and affect theemission control system.
SELECTING THE CORRECT FUELFOR COLD WEATHER
Choosing the Right Fuel: VehiclesOperated Where Ultra Low SulfurDiesel Fuel Is Required (UnitedStates/Canada/Puerto Rico/U.S.Virgin Islands And Other Locales)
Note:Your Warranty will not cover damagecaused by using an improper type of fuel orfuel additive.
Note:Do not blend used engine oil withdiesel fuel under any circumstances.Blending used oil with the fuel significantlyincreases your vehicle’s exhaust emissionsand reduce engine life due to increasedinternal wear.
We recommend Top Tier diesel fuel whereavailable to help minimize engine depositsand maintain optimal vehicle and engineperformance.
For additional information, visitwww.toptiergas.com.
You should use ultra-low sulfur diesel fueldesignated as number 1-D or 2-D with amaximum of 15-ppm sulfur in your dieselvehicle. You can operate your vehicle ondiesel fuels containing up to 20%biodiesel, also known as B20. These fuelsshould meet the ASTM D975 diesel or theASTM D7467 B6-B20 biodiesel industryspecifications. Outside of North America,use fuels meeting EN590 or equivalentlocal market standard.

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
SELECTIVE CATALYTIC

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.

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.
