EMISSION LAW
WARNING: Do not remove or alterthe original equipment floor covering orinsulation between it and the metal floorof the vehicle. The floor covering andinsulation protect occupants of thevehicle from the engine and exhaustsystem heat and noise. On vehicles withno original equipment floor coveringinsulation, do not carry passengers in amanner that permits prolonged skincontact with the metal floor. Failure tofollow these instructions may result infire or personal injury.
U.S. federal laws and certain state lawsprohibit removing or rendering inoperativeemission control system components.Similar federal or provincial laws mayapply in Canada. We do not approve of anyvehicle modification without firstdetermining applicable laws.
Tampering with emissionscontrol systems includingrelated sensors or the DieselExhaust Fluid system can result in reducedengine power and the illumination of theservice engine soon light.
Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative byany person other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery tothe ultimate purchaser or while it is inuse.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessiveexhaust smoke, check for the following:
•A plugged or disconnected air inletsystem hose.
•A plugged engine air filter element.
•Water in the fuel filter and waterseparator.
•A clogged fuel filter.

Noise Emissions Warranty,Prohibited Tampering Acts andMaintenance
On January 1, 1978, Federal regulationbecame effective governing the noiseemission on trucks over 10,000 lb(4,536 kg) Gross Vehicle Weight Rating(GVWR). The preceding statementsconcerning prohibited tampering acts andmaintenance, and the noise warrantyfound in the Warranty Guide, areapplicable to complete chassis cabs over10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
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.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicableexhaust emission standards.
To make sure that the catalytic converterand other emission control componentscontinue to work properly:
•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 293).
•Use only the specified fuel listed.
•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:Resulting component damage maynot be covered by the vehicle Warranty.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.

Illumination of the service engine soonindicator, charging system warning light orthe temperature warning light, fluid leaks,strange odors, smoke or loss of enginepower could indicate that the emissioncontrol system is not working properly.
An improperly operating or damagedexhaust system may allow exhaust toenter the vehicle. Have a damaged orimproperly operating exhaust systeminspected and repaired immediately.
Do not make any unauthorized changes toyour vehicle or engine. By law, vehicleowners and anyone who manufactures,repairs, services, sells, leases, tradesvehicles, or supervises a fleet of vehiclesare not permitted to intentionally removean emission control device or prevent itfrom working. Information about yourvehicle’s emission system is on the VehicleEmission Control Information Decallocated on or near the engine. This decalalso lists engine displacement.
Please consult your warranty informationfor complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1.Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3.The fuel fill inlet may not have closedproperly. See Refueling (page 185).
4.Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctionspresent, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixed city andhighway driving. No additional vehicleservice is required.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness andlead to more costly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
If the service engine soonindicator is on or the bulb doesnot work, your vehicle may needservice. See On-Board Diagnostics.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn. Have your vehiclechecked. If the vehicle has continuousvibration or shudder in the steering wheelwhile braking, have your vehicle checked.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. Wet brakes result in reducedbraking efficiency. Gently press the brakepedal a few times when driving from a carwash or standing water to dry the brakes.
See Cleaning the Wheels (page 344).
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Switch the engine off, move thetransmission to park (P) and apply theparking brake. Inspect the acceleratorpedal and the area around it for any itemsor debris that may be obstructing itsmovement. If none are found and thecondition persists, have your vehiclechecked. If your vehicle has to be towed,we recommend that you contact aprofessional towing service.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional.
If the warning lamp does not illuminateduring start up, remains on or flashes, thesystem may be disabled. Have the systemchecked. If the anti-lock brake system isdisabled, normal braking is still operational.
See Warning Lamps and Indicators(page 105).
Note:Indicators vary depending on region.
This lamp illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional. If it does notilluminate when you switch theignition on, or if it begins to flashat any time except the time during applyingor releasing the parking brake, have thesystem checked.
Regenerative Braking System
This feature simulates the engine brakingof an internal combustion engine andassist the standard brake system whilerecovering some of the energy of motionand storing it in the battery to improve fueleconomy. The standard brake system isdesigned to fully stop the car ifregenerative braking is not available.During regenerative braking, the motor isspun as a generator to create electricalcurrent. This recharges the battery andslows the vehicle. Once the acceleratorpedal is released, the motor changes froman energy user to an energy producer.

Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thegearshift in park (P) to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1.Turn the steering wheel to point yourvehicle tires away from traffic flow.
2.Set your vehicle parking brake.
3.Place the automatic transmission inpark (P).
4.Place wheel chocks in front and backof the trailer wheels. (Chocks notincluded with vehicle.)
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter removing the trailer from the water.
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 in (15 cm) above the bottomedge of the rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Replace the rear axle lubricant anytimethe rear axle has been submerged in water.Water may have contaminated the rearaxle lubricant, which is not normallychecked or changed unless a leak issuspected or other axle repair is required.
