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 position P to aid engine andtransmission cooling and to help A/Cperformance.
•Switch off the speed control withheavy loads or in hilly terrain. Thespeed control may turn offautomatically when you are towing onlong, steep grades.
•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. See Capacities andSpecifications (page 194).
•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 inposition P.
4. Place wheel chocks in front and backof the trailer wheels. (Chocks notincluded with vehicle.)
Your vehicle may be equipped with atemporary or conventional spare tire. A"temporary" spare tire is different in size(diameter or width), tread-type(All-Season or All Terrain) or is from adifferent manufacturer than the road tireson your vehicle. Consult information on thetire label or Safety Compliance label forlimitations when using.
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.

Towing

BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). Duringthis time, your vehicle may exhibit someunusual driving characteristics.
Avoid driving too fast during the first1,000 mi (1,600 km). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Do not tow during the first 1,000 mi(1,600 km).
REDUCED ENGINE
PERFORMANCE
WARNING
If you continue to drive your vehiclewhen the engine is overheating, theengine could stop without warning.Failure to follow this instruction couldresult in the loss of control of your vehicle.
If the engine coolant temperature gaugeneedle moves to the upper limit position,the engine is overheating. See Gauges(page 51).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends onambient temperature, vehicle load andterrain. The engine continues to operatewith limited power for a short period oftime.
If the engine temperature continues to rise,the fuel supply to the engine reduces. Theair conditioning switches off and the enginecooling fan operates continually.
1. Gradually reduce your speed and stopyour vehicle as soon as it is safe to doso.
2. Immediately switch the engine off toprevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See EngineCoolant Check (page 142).
5. Have your vehicle checked as soon aspossible.
ECONOMICAL DRIVING
Fuel economy is affected by several thingssuch as how you drive, the conditions youdrive under and how you maintain yourvehicle.
There are some things to keep in mind thatmay improve your fuel economy:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving (When runningerrands, go to the furthest destinationfirst and then work your way backhome).
•Close the windows for high-speeddriving.
•Drive at reasonable speeds.
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
There are also some things you may wantto avoid doing because they reduce yourfuel economy:
•Avoid sudden or hard accelerations.
•Avoid revving the engine before turningoff the car.
•Avoid long idle periods.
•Do not warm up your vehicle on coldmornings.

Location of the Tire Label
You can find a Tire Labelcontaining tire inflation pressureby tire size and other importantinformation located on the B-Pillaror the edge of the driver's door.
Inflating Your Tires
Safe operation of your vehiclerequires that your tires areproperly inflated. Remember thata tire can lose up to half of its airpressure without appearing flat.
Every day before you drive, checkyour tires. If one looks lower thanthe others, use a tire gauge tocheck pressure of all tires andadjust if required.
At least once a month and beforelong trips, inspect each tire andcheck the tire pressure with a tiregauge (including spare, ifequipped). Inflate all tires to theinflation pressure recommended
by Ford Motor Company.

You are strongly urged to buy areliable tire pressure gauge, asautomatic service station gaugesmay be inaccurate. Fordrecommends the use of a digitalor dial-type tire pressure gaugerather than a stick-type tirepressure gauge.
Use the recommended coldinflation pressure for optimum tireperformance and wear.Under-inflation or over-inflationmay cause uneven treadwearpatterns
WARNING
Under-inflation is the mostcommon cause of tire failuresand may result in severe tirecracking, tread separation orblowout, with unexpected loss ofvehicle control and increased riskof injury. Under-inflation increasessidewall flexing and rollingresistance, resulting in heatbuildup and internal damage tothe tire. It also may result inunnecessary tire stress, irregularwear, loss of vehicle control andaccidents. A tire can lose up tohalf of its air pressure and notappear to be flat!
Always inflate your tires to theFord recommended inflationpressure even if it is less than themaximum inflation pressureinformation found on the tire. TheFord recommended tire inflation
pressure is found on the SafetyCompliance Certification Label or
Tire Label (affixed to either thedoor hinge pillar, door-latch post,or the door edge that meets thedoor-latch post, next to thedriver's seating position), or TireLabel located on the B-pillar orthe edge of the driver's door.Failure to follow the tire pressurerecommendations can causeuneven treadwear patterns andadversely affect the way yourvehicle handles
Note:Do not reduce tire pressureto change the ride characteristicsof the vehicle. If you do notmaintain the inflation pressure atthe levels specified by Ford, yourvehicle may experience a conditionknown as shimmy. Shimmy is asevere vibration and oscillation inthe steering wheel after the vehicletravels over a bump or dip in theroad that does not dampen out byitself. Shimmy may result fromsignificant under-inflation of thetires, improper tires (load range,size, or type), or vehiclemodifications such as lift-kits. Inthe event that your vehicleexperiences shimmy, you shouldslowly reduce speed by either liftingoff the accelerator pedal or lightlyapplying the brakes. The shimmyceases as the vehicle speeddecreases.
Maximum Inflation Pressure isthe tire manufacturer's maximumpermissible pressure and thepressure at which the maximum
load can be carried by the tire. Thispressure is normally higher than

Note:Some spare tires operate ata higher inflation pressure than theother tires. For T type mini-sparetires, (see the Dissimilar sparewheel and tire assemblyinformation for a description. Storeand maintain at 60 psi (4.15 bar).For full-size and dissimilar sparetires, see the Dissimilar spare wheeland tire assembly information fora description. Store and maintainat the higher of the front and rearinflation pressure as shown on theSafety Compliance CertificationLabel or Tire Label.
6. Visually inspect the tires tomake sure there are no nails orother objects embedded thatcould poke a hole in the tire andcause an air leak.
7. Check the sidewalls to makesure there are no gouges, cuts orbulges.
Tire Inflation Information
WARNING
An inflated tire and rim canbe very dangerous ifimproperly used, serviced ormaintained. To reduce the risk ofserious injury, never attempt tore-inflate a tire which has been runflat or seriously under-inflatedwithout first removing the tirefrom the wheel assembly forinspection. Do not attempt to addair to tires or replace tires orwheels without first takingprecautions to protect personsand property.
All tires with Steel Carcass Plies(if equipped):
This type of tire utilizes steel cordsin the sidewalls. As such, theycannot be treated like normal lighttruck tires. Tire service, includingadjusting tire pressure, must beperformed by personnel trained,supervised and equippedaccording to Federal OccupationalSafety and Health Administrationregulations. For example, duringany procedure involving tireinflation, the technician orindividual must utilize a remoteinflation device, and ensure thatall persons are clear of thetrajectory area.

WARNINGS
Only use replacement tiresand wheels that are the samesize, load index, speed rating andtype (such as P-metric versusLT-metric or all-season versusall-terrain) as those originally
provided by Ford. Therecommended tire and wheel size
WARNINGS
may be found on either the SafetyCompliance Certification Label(affixed to either the door hingepillar, door-latch post, or the dooredge that meets the door-latchpost, next to the driver's seatingposition), or the Tire Label whichis located on the B-Pillar or edgeof the driver's door. If thisinformation is not found on theselabels, then you should contactyour authorized dealer as soon aspossible. Use of any tire or wheelnot recommended by Ford canaffect the safety and performanceof your vehicle, which could resultin an increased risk of loss ofvehicle control, vehicle rollover,personal injury and death.
To reduce the risk of seriousinjury, when mountingreplacement tires and wheels, youshould not exceed the maximumpressure indicated on the sidewallof the tire to set the beads withoutadditional precautions listedbelow. If the beads do not seat atthe maximum pressure indicated,re-lubricate and try again.
For a mounting pressuremore than 20 psi (1.38 bar)greater than the maximumpressure, a Ford dealer or othertire service professional should dothe mounting.
