requirements of law. Ford recommendschecking with a NHTSA Certified ChildPassenger Safety Technician (CPST) andconsult your pediatrician to make sure yourchild seat is appropriate for your child, andis compatible with and properly installedin your vehicle. To locate a child seat fittingstation and CPST, contact the NHTSA tollfree at 1-888-327-4236 or go tohttp://www.nhtsa.dot.gov. In Canada,check with your local St. John Ambulanceoffice for referral to a CPST or for furtherinformation, contact your provincialministry of transportation, locate your localSt. John Ambulance office by searching forSt. John Ambulance on the internet, orTransport Canada at 1-800-333-0371(http://www.tc.gc.ca). Failure to properlyrestrain children in safety seats madeespecially for their height, age, and weightmay result in an increased risk of seriousinjury or death to your child.

PRINCIPLE OF OPERATION
WARNINGS
Airbags do not inflate slowly orgently, and the risk of injury from adeploying airbag is the greatest closeto the trim covering the airbag module.
All occupants of your vehicle,including the driver, should alwaysproperly wear their safety belts, evenwhen an airbag supplemental restraintsystem is provided. Failure to properly wearyour safety belt could seriously increasethe risk of injury or death.
Always transport children 12 yearsold and under in the back seat andalways properly use appropriatechild restraints. Failure to follow this couldseriously increase the risk of injury or death.
Never place your arm over the airbagmodule as a deploying airbag canresult in serious arm fractures orother injuries.
Airbags can kill or injure a child in achild seat. Never place a rear-facingchild seat in front of an active airbag.If you must use a forward-facing child seatin the front seat, move the seat upon whichthe child seat is installed all the way back.
Do not attempt to service, repair, ormodify the airbag supplementalrestraint systems or its fuses as youcould be seriously injured or killed. Contactyour authorized dealer as soon as possible.
Several airbag system componentsget hot after inflation. To avoid riskof injury, do not touch them afterinflation.
If the airbag has deployed, the airbagwill not function again and must bereplaced immediately. If the airbagis not replaced, the unrepaired area willincrease the risk of injury in a crash.
The airbags are a supplemental restraintsystem and are designed to work with thesafety belts to help protect the driver andright front passenger from certain upperbody injuries. Airbags do not inflate slowly;there is a risk of injury from a deployingairbag.
Note:You will hear a loud bang and see acloud of harmless powdery residue if anairbag deploys. This is normal.
The airbags inflate and deflate rapidlyupon activation. After airbag deployment,it is normal to notice a smoke-like, powderyresidue or smell the burnt propellant. Thismay consist of cornstarch, talcum powder(to lubricate the bag) or sodiumcompounds (for example, baking soda)that result from the combustion processthat inflates the airbag. Small amounts ofsodium hydroxide may be present whichmay irritate the skin and eyes, but none ofthe residue is toxic.
While the system is designed to helpreduce serious injuries, contact with adeploying airbag may also cause abrasionsor swelling. Temporary hearing loss is alsoa possibility as a result of the noiseassociated with a deploying airbag.Because airbags must inflate rapidly andwith considerable force, there is the risk ofdeath or serious injuries such as fractures,facial and eye injuries or internal injuries,particularly to occupants who are notproperly restrained or are otherwise out ofposition at the time of airbag deployment.Thus, it is extremely important thatoccupants be properly restrained as faraway from the airbag module as possiblewhile maintaining vehicle control.
Routine maintenance of the airbags is notrequired.

WARNINGS
the protection of the airbag, you also mayreduce the effectiveness of your safety beltsystem, which was designed to work withthe airbag. If you are not a person whomeets the requirements stated in theNational Highway Traffic SafetyAdministration or Transport Canadadeactivation criteria turning off the airbagcan increase the risk of serious injury ordeath in a crash.
If your vehicle has rear seats, alwaystransport children who are 12 andyounger in the rear seat. Always usesafety belts and child restraints properly.Do not place a child in a rear facing infantseat in the front seat unless your vehicle isequipped with an airbag on and off switchand the passenger airbag is turned off. Thisis because the back of the infant seat istoo close to the inflating airbag and therisk of a fatal injury to the infant when theairbag inflates is substantial.
If the pass airbag off light isilluminated when the passengerairbag switch is on and the ignitionis on, have the passenger airbag switchserviced at your authorized dealerimmediately.
The passenger airbag remains off until youturn it back on.
1.Insert the ignition key and turn theswitch to ON.
2.The pass airbag off light will brieflyilluminate when the ignition is turnedto on. This indicates that the passengerairbag is operational.
The passenger side airbag should alwaysbe on (the pass airbag off light should notbe illuminated) unless the passenger is aperson who meets the requirements statedeither in Category 1, 2 or 3 of the NationalHighway Traffic Safety Administration orTransport Canada deactivation criteriawhich follows.
The vast majority of drivers and passengersare much safer with an airbag thanwithout. To do their job and reduce the riskof life threatening injuries, airbags mustopen with great force, and this force canpose a potentially deadly risk in somesituations, particularly when a front seatoccupant is not properly buckled up. Themost effective way to reduce the risk ofunnecessary airbag injuries withoutreducing the overall safety of the vehicleis to make sure all occupants are properlyrestrained in the vehicle, especially in thefront seat. This provides the protection ofsafety belts and permits the airbags toprovide the additional protection they weredesigned to provide. If you choose todeactivate your airbag, you are losing thevery significant risk reducing benefits ofthe airbag and you are also reducing theeffectiveness of the safety belts, becausesafety belts in modern vehicles aredesigned to work as a safety system withthe airbags.

Transport Canada Deactivation Criteria(Canada Only)
WARNING
This vehicle has special energymanagement safety belts for thedriver and right front passenger.These particular belts are specificallydesigned to work with airbags to helpreduce the risk of injury in a crash. Theenergy management safety belt isdesigned to give or release additional beltwebbing in some accidents to reduceconcentration of force on an occupant'schest and reduce the risk of certain bonefractures and injuries to underlying organs.In a crash, if the airbag is turned off, thisenergy management safety belt mightpermit the person wearing the belt to moveforward enough to incur a serious or fatalinjury. The more severe the crash, and theheavier the occupant, the greater the riskis. Be sure the airbag is turned on for anyperson who does not qualify under theNational Highway Traffic SafetyAdministration deactivation criteria.
1.Infant: An infant (less than 1 year old)must ride in the front seat because:
•my vehicle has no rear seat;
•the rear seat in my vehicle cannotaccommodate a rear-facing infantseat;
•the infant has a medical conditionwhich, according to the infant'sphysician, makes it necessary for theinfant to ride in the front seat so thatthe driver can monitor the infant'scondition.
2.Child age 12 or under: A child age 12 orunder must ride in the front seat because:
•my vehicle has no rear seat;
•although children age 12 and under ridein the rear seat whenever possible,children age 12 and under have nooption but to sometimes ride in thefront seat because rear seat space isinsufficient;
•the child has a medical condition that,according to the child's physician,makes it necessary for the child to ridein the front seat so that the driver canmonitor the child's condition.
3.Medical condition: A passenger has amedical condition that, according to his orher physician:
•poses a special risk for the passengerif the airbag deploys; and
•makes the potential harm from thepassenger airbag deployment greaterthan the potential harm from turningoff the airbag and experiencing a crashwithout the protection offered by theairbag
Proper Driver and Front PassengerSeating Adjustment
WARNING
The National Highway Traffic SafetyAdministration recommends aminimum distance of at least 10inches (25 centimeters) between anoccupant’s chest and the driver airbagmodule.
To properly position yourself away fromthe airbag:
•Move your seat to the rear as far as youcan while still reaching the pedalscomfortably.
•Recline the seat slightly (one or twodegrees) from the upright position.

How Your Vehicle Differs FromOther Vehicles
WARNING
Vehicles with a higher center ofgravity such as utility and four-wheeldrive vehicles handle differently thanvehicles with a lower center of gravity.Utility and four-wheel drive vehicles arenot designed for cornering at speeds ashigh as passenger cars any more thanlow-slung sports cars are designed toperform satisfactorily under off-roadconditions. Avoid sharp turns, excessivespeed and abrupt maneuvers in thesevehicles. Failure to drive cautiously couldresult in an increased risk of loss of vehiclecontrol, vehicle rollover, personal injury anddeath.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle may behigher to allow it to travel over roughterrain without getting hung up ordamaging underbody components.
The differences that make your vehicle soversatile also make it handle differentlythan an ordinary passenger car.
Maintain steering wheel control at alltimes, especially in rough terrain. Sincesudden changes in terrain can result inabrupt steering wheel motion, make sureyou grip the steering wheel from theoutside. Do not grip the spokes.
Drive cautiously to avoid vehicle damagefrom concealed objects such as rocks andstumps.
You should either know the terrain orexamine maps of the area before driving.Map out your route before driving in thearea. To maintain steering and brakingcontrol of your vehicle, you must have allfour wheels on the ground and they mustbe rolling, not sliding or spinning.
Driving Off-Road With Truck andUtility Vehicles
Note:On some models, the initial shift fromtwo-wheel drive to four-wheel drive whilethe vehicle is moving can cause somemomentary clunk and ratcheting sounds.This is the front drivetrain coming up tospeed and the automatic locking hubsengaging and is not cause for concern.
Note:Your vehicle may be equipped witha front air dam that can become damaged(due to reduced ground clearance) whentaking your vehicle off-road. This air damcan be taken off by removing two bolts.
Four-wheel drive vehicles are speciallyequipped for driving on sand, snow, mudand rough terrain and have operatingcharacteristics that are somewhatdifferent from conventional vehicles, bothon and off the road.
Power is supplied to all four wheelsthrough a transfer case. On Four-wheeldrive vehicles, the transfer case allows youto select 4WD when necessary.Information on transfer case operation andshifting procedures can be found in thischapter. Information on transfer casemaintenance can be found in theMaintenance chapter. You should becomethoroughly familiar with this informationbefore you operate your vehicle.

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
