RESTARTING THE ENGINE AFTERSTOPPING IT - VEHICLES WITH:PUSH BUTTON START
The system allows you to start the enginewithin 10 seconds of switching it off, evenif it does not detect a valid passive key.
Within 10 seconds of switching the engineoff, fully press the brake pedal and pressthe push button ignition switch. After 10seconds, you can no longer start the engineif the system does not detect a validpassive key.
When you start the engine, it remainsrunning until you press the push buttonignition switch, even if your vehicle doesnot detect a valid passive key. If you openand close a door when the engine isrunning, the system searches for a validpassive key.
ENGINE BLOCK HEATER (IF
EQUIPPED)
ENGINE BLOCK HEATERPRECAUTIONS
WARNING: Failure to follow engineblock heater instructions could result inproperty damage or serious personalinjury.
WARNING: Do not use your heaterwith ungrounded electrical systems ortwo-pronged adapters. There is a risk ofelectrical shock.
WARNING: Do not fully close thehood, or allow it to drop under its ownweight when using the engine blockheater. This could damage the powercable and may cause an electrical shortresulting in fire, injury and propertydamage.
We recommend that you do the followingfor a safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified byUnderwriter’s Laboratory (UL) orCanadian Standards Association(CSA). This extension cord must besuitable for use outdoors, in coldtemperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and engine blockheater cord plug connections are freeand clear of water. This could cause anelectric shock or fire.
•If the engine block heater cord is underthe hood, do not remove the wiringfrom its original location. Do not closethe hood on the extension wiring.
•Park your vehicle in a clean area, clearof combustible materials.
•Firmly connect the engine block heatercord and the extension cord.
•Check the extension cord for heatanywhere when the system has beenoperating for approximately 30minutes.
•Unplug and properly stow the systembefore starting and driving your vehicle.The protective cover seals theterminals of the engine block heatercord plug when not in use.
•Check the engine block heater systemfor proper operation before winter.

Before you start manual regeneration, dothe following:
•Make sure the parking brake is on.
•Shift into park (P) on stable, levelground.
•Park your vehicle outside of anystructure.
•Park your vehicle 10–15 ft (3–5 m)away from any obstructions and awayfrom materials that can easily combustor melt, for example paper, leaves,petroleum products, fuels, plastics andother dry organic material.
•Make sure there is a minimum of 1/8tank of fuel.
•Make sure all fluids are at proper levels.
DIESEL PARTICULATE FILTERMANUAL REGENERATIONLIMITATIONS
You cannot use manual regeneration untilthe diesel particulate filter load percentagehas reached 100% or Full. The dieselparticulate filter load percentagefluctuates up and down when driving yourvehicle due to active and passiveregenerations.
If your vehicle is operated with significantstationary operation, low speed drivecycles less than 25 mph (40 km/h), shortdrive cycles, drive time less than 15 minutesor the vehicle does not fully warm up,passive and active regeneration may notsufficiently clean the diesel particulatefilter system.
Aftermarket devices or modifications tothe exhaust system may reduce theeffectiveness of the exhaust system aswell as cause damage to the exhaustsystem or engine. This may also degradevehicle performance and could lead toengine damage that may not be coveredby the vehicle Warranty.
STARTING DIESEL PARTICULATEFILTER MANUAL REGENERATION
Start with your vehicle engine and when ithas reached the normal operatingtemperature, press the information displaycontrol button on the steering wheel. SeeInstrument Cluster Display (page 143).
If the diesel particulate filter is near or atsaturation, a message requestingpermission to initiate filter cleaningappears in the information display. SeeDiesel Particulate Filter – InformationMessages (page 224). Answer yes to thisprompt and then follow the next promptsregarding exhaust position required toinitiate manual regeneration. Be sure tounderstand each prompt. If you are notsure what is being asked by each prompt,contact an authorized dealer. The displayconfirms the operation has started andwhen it has finished. You can also drive toclean the filter.
When the system is at the pointof oversaturation, themalfunction indicator lampilluminates and a message appears in theinformation display. You cannot initiatefilter cleaning. You must have your vehiclechecked as soon as possible.
Once manual regeneration starts, enginespeed increases and the cooling fan speedincreases. You will hear a change in audiblesound due to engine speed and cooling fanspeed increases.
It is not necessary to open the hood on theengine compartment. Once manualregeneration completes, the engine speedreturns to normal idling. The exhaustsystem remains very hot for severalminutes even after regeneration iscomplete. Do not reposition the vehicleover materials that could burn until the

If there are any issues with thediesel particulate filter system,or when the system is at thepoint of oversaturation, thepowertrain warning lamp andthe malfunction indicator lampilluminate to inform you that your vehiclerequires service. You may not be able toinitiate filter cleaning. Have your vehiclechecked as soon as possible.

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.
