Note:Do not insert objects other than anaccessory plug into the power point. Thiswill damage the outlet and blow the fuse.
Note:Do not hang any type of accessory oraccessory bracket from the plug.
Note:Do not use the power point over thevehicle capacity of 12 volt DC 180 watts ora fuse may blow.
Note:Do not use the power point foroperating a cigar lighter element.
Note:Improper use of the power point cancause damage not covered by yourwarranty.
Note:Always keep the power point capsclosed when not in use.
Run the engine for full capacity use of thepower point. To prevent the battery frombeing discharged:
•do not use the power point longer thannecessary when the engine is notrunning
•do not leave devices plugged inovernight or when the vehicle is parkedfor extended periods.
Locations
Power points may be found:
•On the instrument panel (twolocations).
•Inside the center console.
•On the rear of the center console.
•Inside the front under-seat storagecompartment (if equipped).
•Inside the rear under-seat storagecompartment (if equipped).
110 Volt AC Power Points (If Equipped)
WARNING
Do not keep electrical devicesplugged in the power points whenthe devices are not in use. Do not useany extension cord with the 110 volt ACpower points, since it will defeat the safetyprotection design. Do not use a singlepower point to power multiple devices.

FUEL CONSUMPTION
Empty reserve is the amount of fuelremaining in the tank after the fuel gaugeindicates empty. The amount of usablefuel in the empty reserve varies and shouldnot be relied upon to increase driving range.
•The usable capacity of the fuel tank isthe amount of fuel that can be addedinto the tank after the gauge indicatesempty
•The advertised capacity is the total fueltank size.  See Capacities andSpecifications (page 292).  It is thecombined usable capacity plus theempty reserve.
•Due to the empty reserve, you may notbe able to refuel the full amount of theadvertised capacity of the fuel tankeven when the fuel gauge reads empty.
Filling the Tank
For consistent results when filling the fueltank:
•Turn the ignition off before fueling; aninaccurate reading results if the engineis left running.
•Use the same fill rate(low-medium-high) each time the tankis filled.
•Allow no more than two automaticclick-offs when filling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Do not measure fuel economy during thefirst 1000 miles (1600 kilometers) ofdriving (this is your engine’s break-inperiod); a more accurate measurement isobtained after 2000 miles - 3000 miles(3200 kilometers - 4800 kilometers). Also,fuel expense, frequency of fill ups or fuelgauge readings are not accurate ways tomeasure fuel economy.
1.Fill the fuel tank completely and recordthe initial odometer reading.
2. Each time you fill the tank, record theamount of fuel added.
3.After at least 3 to 5 tank fill ups, fill thefuel tank and record the currentodometer reading.
4. Subtract your initial odometer readingfrom the current odometer reading.
5. Calculate fuel economy by dividingmiles traveled by gallons used (ForMetric: Multiply liters used by 100, thendivide by kilometers traveled).
Keep a record for at least 1 month andrecord the type of driving (city or highway).This provides an accurate estimate of thevehicle’s fuel economy under currentdriving conditions. Additionally, keepingrecords during summer and winter showhow temperature impacts fuel economy.In general, lower temperatures mean lowerfuel economy.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Carrying unnecessary weight mayreduce fuel economy (approximately1 mpg [0.4 km/L] is lost for every 400pounds [180 kilograms] of weightcarried).

Fuel and Refueling 

WARNING
The appropriate loadingcapacity of your vehicle canbe limited either by volumecapacity (how much space isavailable) or by payload capacity(how much weight the vehicleshould carry). Once you havereached the maximum payload ofyour vehicle, do not add morecargo, even if there is spaceavailable. Overloading orimproperly loading your vehiclecan contribute to loss of vehiclecontrol and vehicle rollover.

2.Determine the combinedweight of the driver andpassengers that will be ridingin your vehicle.
3.Subtract the combined weightof the driver and passengersfrom XXX kg or XXX lb.
4.The resulting figure equals theavailable amount of cargo andluggage load capacity. Forexample, if the “XXX” amountequals 1,400 lb. and there willbe five 150 lb. passengers inyour vehicle, the amount ofavailable cargo and luggageload capacity is 650 lb.(1400-750 (5 x 150) = 650 lb.)
5.Determine the combinedweight of luggage and cargobeing loaded on the vehicle.That weight may not safelyexceed the available cargo andluggage load capacitycalculated in Step 4.
6.If your vehicle will be towing atrailer, load from your trailerwill be transferred to yourvehicle. Consult this manual todetermine how this reduces theavailable cargo and luggageload capacity of your vehicle.
The following gives you a fewexamples on how to calculate theavailable amount of cargo andluggage load capacity:
*Suppose your vehicle has a1400-pound (635-kilogram) cargoand luggage capacity. You decideto go golfing. Is there enough loadcapacity to carry you, four of yourfriends and all the golf bags? Youand four friends average 220pounds (99 kilograms) each andthe golf bags weigh approximately30 pounds (13.5 kilograms) each.The calculation would be: 1400 -(5 x 220) - (5 x 30) = 1400 - 1100- 150 = 150 pounds. Yes, you haveenough load capacity in yourvehicle to transport four friendsand your golf bags. In metric units,the calculation would be: 635kilograms - (5 x 99 kilograms) -(5 x 13.5 kilograms) = 635 - 495 -67.5 = 72.5 kilograms.
*Suppose your vehicle has a1400-pound (635-kilogram) cargoand luggage capacity. You andone of your friends decide to pickup cement from the local homeimprovement store to finish thatpatio you have been planning forthe past two years. Measuring theinside of the vehicle with the rearseat folded down, you have roomfor twelve 100-pound(45-kilogram) bags of cement. Doyou have enough load capacity totransport the cement to yourhome? If you and your friend eachweigh 220 pounds (99 kilograms),the calculation would be: 1400 -(2 x 220) - (12 x 100) = 1400 - 440- 1200 = - 240 pounds. No, you donot have enough cargo capacity
to carry that much weight. Inmetric units, the calculation would
182
Super Duty (TFA)
Load Carrying 

be: 635 kilograms - (2 x 99kilograms) - (12 x 45 kilograms) =635 - 198 - 540 = -103 kilograms.You will need to reduce the loadweight by at least 240 pounds(104 kilograms). If you removethree 100-pound (45-kilogram)cement bags, then the loadcalculation would be:1400 - (2 x220) - (9 x 100) = 1400 - 440 -900 = 60 pounds. Now you havethe load capacity to transport thecement and your friend home. Inmetric units, the calculation wouldbe: 635 kilograms - (2 x 99kilograms) - (9 x 45 kilograms) =635 - 198 - 405 = 32 kilograms.
The above calculations alsoassume that the loads arepositioned in your vehicle in amanner that does not overloadthe Front or the Rear Gross AxleWeight Rating specified for yourvehicle on the Safety ComplianceCertification Label. The label shallbe affixed to either the door hingepillar, door-latch post, or the dooredge that meets the door-latchpost, next to the driver's seatingposition.
Special Loading Instructionsfor Owners of Pick-up Trucksand Utility-type Vehicles
WARNING
Loaded vehicles may handledifferently than unloadedvehicles. Extra precautions, suchas slower speeds and increasedstopping distance, should betaken when driving a heavilyloaded vehicle.
Your vehicle can haul more cargoand people than most passengercars. Depending upon the typeand placement of the load,hauling cargo and people mayraise the center of gravity of thevehicle.

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR orthe GAWR specified on thecertification label.
Towing trailers beyond themaximum recommendedgross trailer weight exceeds thelimit of the vehicle and couldresult in engine damage,transmission damage, structuraldamage, loss of vehicle control,vehicle rollover and personalinjury.
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See the Fuseschapter.
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle.
Towing a trailer places an extraload on your vehicle's engine,transmission, axle, brakes, tiresand suspension. Inspect thesecomponents periodically during,and after, any towing operation.
Load Placement
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight.
•Select a tow bar with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, the trailer frameshould be level, or slightlyangled down toward yourvehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibrationor shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual.  See Load Limit (page176).  You can also find theinformation in the RV & TrailerTowing Guide, available at anauthorized dealer.

Trailer Lamps
WARNING
Never connect any trailer lamp wiringto the vehicle's tail lamp wiring; thismay damage the electrical systemresulting in fire. Contact your authorizeddealer as soon as possible for assistancein proper trailer tow wiring installation.Additional electrical equipment may berequired.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, turn signals and hazard lights areworking.
Using a Step Bumper (If Equipped)
The rear bumper is equipped with anintegral hitch and only requires a ball witha one-inch (25.4 millimeter) shankdiameter. The bumper has a 5000-pound(2268 kilogram) trailer weight and a500-pound (227 kilogram) tongue weightcapacity
If it is necessary to relocate the hitch ballposition, you must install a frame-mountedtrailer hitch.
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 (113km/h) during the first 500 miles (800kilometers).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 miles (80kilometers).
•When stopped in congested or heavytraffic during hot weather, place thegearshift in position 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.
•If your vehicle is equipped withAdvanceTrac with RSC, this systemmay turn on during typical corneringmaneuvers with a heavily loaded trailer.This is normal. Turning the corner at aslower speed while towing may reducethis tendency.
•If you are towing a trailer frequently inhot weather, hilly conditions, at thegross combined weight rating (or anycombination of these factors), considerrefilling your rear axle with syntheticgear lubricant (if the axle is not alreadyfilled with it).  See Capacities andSpecifications (page 292).
