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 (page178). You can also find theinformation in the RV & TrailerTowing Guide, available at anauthorized dealer.

Towing

•Service your vehicle morefrequently if you tow a trailer.See your scheduledmaintenance information.
•If you use a rental trailer, followthe instructions the rentalagency gives you.
See Load limits in the LoadCarrying chapter for loadspecification terms found on thetire label and Safety Compliancelabel and instructions oncalculating your vehicle's load.
Remember to account for thetrailer tongue weight as part ofyour vehicle load when calculatingthe total vehicle weight.
Trailer Towing Connector
When attaching the trailer wiringconnector to your vehicle, only usea proper fitting connector thatworks with the vehicle and trailerfunctions. Some seven-positionconnectors may have the SAEJ2863 logo, which confirms that itis the proper wiring connector andworks correctly with your vehicle.

•When stopped in congested orheavy traffic during hotweather, place the gearshift inposition P to aid engine andtransmission cooling and tohelp A/C performance.
•Turn off the speed control withheavy loads or in hilly terrain.The speed control may turn offautomatically when you aretowing on long, steep grades.
•Shift to a lower gear whendriving down a long or steephill. Do not apply the brakescontinuously, as they mayoverheat and become lesseffective.
•If your transmission is equippedwith a Grade Assist orTow/Haul feature, use thisfeature when towing. Thisprovides engine braking andhelps eliminate excessivetransmission shifting foroptimum fuel economy andtransmission cooling.
•If your vehicle is equipped withAdvanceTrac with RSC, thissystem may turn on duringtypical cornering maneuverswith a heavily loaded trailer.This is normal. Turning thecorner at a slower speed whiletowing may reduce thistendency.
•If you are towing a trailerfrequently in hot weather, hillyconditions, at the grosscombined weight rating (or anycombination of these factors),consider refilling your rear axlewith synthetic gear lubricant (ifthe axle is not already filledwith it). See Capacities andSpecifications (page 301).
•Allow more distance forstopping with a trailerattached. Anticipate stops andbrake gradually.
•Avoid parking on a grade.However, if you must park on agrade:
1. Turn the steering wheel topoint your vehicle tires awayfrom traffic flow.
2.Set your vehicle parking brake.
3.Place the automatictransmission in position P.
4.Place wheel chocks in frontand back of the trailer wheels.(Chocks not included withvehicle.)
Your vehicle may be equippedwith a temporary or conventionalspare tire. A "temporary" spare tireis different in size (diameter orwidth), tread-type (All-Season orAll Terrain) or is from a differentmanufacturer than the road tireson your vehicle. Consultinformation on the tire label orSafety Compliance label forlimitations when using.

•Use a damper device such as a tarp,heavy blanket or piece of carpetdraped over the recovery strap to helpabsorb the energy in the event thestrap breaks.
•Make sure the stuck vehicle is notloaded heavier than its gross vehicleweight rating specified on thecertification label.
•Always align the tow vehicle and stuckvehicle in a straight line (within 10degrees).
•Keep bystanders to the sides of thevehicle, at a distance of at least twicethe length of the recovery strap. Thishelps avoid injury from the hazard of arecovery hook or strap breaking, or avehicle lurching into their path.
TRANSPORTING THE VEHICLE
If you need to have your vehicle towed,contact a professional towing service or,if you are a member of a roadsideassistance program, your roadsideassistance service provider.
We recommend the use of a wheel lift anddollies or flatbed equipment to tow yourvehicle. Do not tow with a slingbelt. FordMotor Company has not approved aslingbelt towing procedure. Vehicledamage may occur if towed incorrectly, orby any other means.
Ford Motor Company produces a towingmanual for all authorized tow truckoperators. Have your tow truck operatorrefer to this manual for proper hook-upand towing procedures for your vehicle.
It is acceptable to have your two-wheeldrive vehicle towed with the front wheelson the ground (without dollies) and therear wheels off the ground.
We recommend towing a four-wheel drivevehicle with all wheels off the ground, suchas using a wheel lift and dollies or flatbedequipment. However, it is acceptable touse a wheel lift to raise the rear of yourvehicle so long as, depending on vehicleconfiguration, you perform the followingbefore towing:
•If your vehicle is equipped with amanual-shift transfer case, make surethe front wheel hub locks are in theFREE position before towing.
•If your vehicle is equipped with anelectronic shift-on-the-fly transfercase, make sure you turn thefour-wheel drive control to the 2Hposition before towing.
Note:Towing an electronic shift-on-the-flyfour-wheel drive vehicle with the frontwheels on the ground without disengagingthe front hubs may cause damage to theautomatic transmission.

Towing

•Transmissions give their best fueleconomy when operated in the topcruise gear and with steady pressureon the gas pedal.
•Four-wheel-drive operation (ifequipped) is less fuel efficient thantwo-wheel-drive operation.
•Close the windows for high-speeddriving.
DRIVING THROUGH WATER
Note:Driving through deep water abovethe recommended levels can cause vehicledamage.
If driving through deep or standing wateris unavoidable, proceed very slowly. Neverdrive through water that is higher than thebottom of the wheel rims (for cars) or thebottom of the hubs (for trucks).
When driving through water, traction orbrake capability may be limited. Also,water may enter your engine’s air intakeand severely damage your engine or yourvehicle may stall.
Once through the water, always dry thebrakes by moving your vehicle slowly whileapplying light pressure on the brake pedal.Wet brakes do not stop the vehicle asquickly as dry brakes.
FLOOR MATS
WARNINGS
Always use floor mats that aredesigned to fit the foot well of yourvehicle, leaving the pedal areaunobstructed, and which can be firmlysecured to retention posts so that theycannot slip out of position and interferewith the pedals or impair safe operation ofyour vehicle in other ways.
Incorrectly fitted floor mats cancause the accelerator pedal tobecome stuck in the open position.This can cause loss of vehicle control.
Always correctly install the floormats to the retention posts so thatthey cannot slip out of position orobstruct pedal operation.
Do not place unsecured floor matsor any other covering in the foot well.
Do not place additional floor matsor any other covering on top of theoriginal floor mats. This will reducethe pedal clearance and interfere with thepedal operation.
Do not allow objects to fall orbecome trapped under the pedals ofyour vehicle. This can cause loss ofvehicle control.
Carry out regular inspections to makesure the floor mats are secure.

Snowplowing with your AirbagEquipped Vehicle
WARNINGS
Do not attempt to service, repair, ormodify the airbag supplementalrestraint system (SRS) or its fuses.See your Ford or Lincoln Mercury dealer.
Additional equipment such assnowplow equipment may affect theperformance of the airbag sensorsincreasing the risk of injury. Please refer tothe Body Builders Layout Book forinstructions about the appropriateinstallation of additional equipment.
All occupants of the vehicle,including the driver, should alwaysproperly wear their safety belts, evenwhen provided with an airbagsupplemental restraint system (SRS).
Your vehicle is equipped with a driver andpassenger airbag supplemental restraintsystem. The supplemental restraint systemwill activate in certain frontal and offsetfrontal collisions when the vehicle sustainssufficient frontal deceleration.
Careless or high speed driving whileplowing snow that results in sufficientvehicle decelerations can deploy theairbag. Such driving also increases the riskof accidents
Never remove or defeat the trippingmechanisms designed into the snowremoval equipment by its manufacturer.Doing so may cause damage to the vehicleand the snow removal equipment as wellas possible airbag deployment.
Engine temperature while plowing
When driving with a plow, your engine mayrun at a higher temperature than normalbecause the attached snowplow blade willrestrict airflow to the radiator.
•If you are driving more than 14.91 mi(24 km) at temperatures abovefreezing, angle the plow blade eitherfull left or full right to providemaximum airflow to the radiator.
•If you are driving less than 14.91 mi(24 km) at speeds up to 44.7 mph(72 km/h) in cold weather, you will notneed to worry about blade position toprovide maximum airflow.
Transmission operation whileplowing
WARNING
Do not spin the wheels at over34.2 mph (55 km/h). The tires mayfail and injure a passenger orbystander.
•Shift transfer case to 4L (4WD Low)when plowing in small areas at speedsbelow 5 mph (8 km/h).
•Shift transfer case to 4H (4WD High)when plowing larger areas or light snowat higher speeds. Do not exceed 15 mph(24 km/h).
•Do not shift the transmission from aforward gear to R (Reverse) until theengine is at idle and the wheels havestopped.
