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.

Supplementary Restraints System

After all occupants have adjusted theirseats and put on seatbelts, it is veryimportant that they continue to sitproperly. Properly seated occupants situpright, lean against the seat back, andcenter themselves on the seat cushion,with their feet comfortably extended onthe floor. Sitting improperly can increasethe chance of injury in a crash event. Forexample, if an occupant slouches, liesdown, turns sideways, sits forward, leansforward or sideways, or puts one or bothfeet up, the chance of injury during a crashgreatly increases.
Children and Airbags
WARNING
Airbags can kill or injure a child in achild restraint. Never place arear-facing child restraint in front ofan active airbag. If you must use aforward-facing child restraint in the frontseat, move the seat upon which the childseat is installed all the way back.
Children must always be properlyrestrained. Accident statistics suggest thatchildren are safer when properly restrainedin the rear seating positions than in thefront seating position. Failure to followthese instructions may increase the risk ofinjury in a crash.
If two adults and a child occupy a RegularCab, properly restrain the child in thecenter front unless doing so would interferewith driving your vehicle. This provides lapand shoulder belt protection for alloccupants, and airbag protection for theadults. A child or infant properly restrainedin the center front seat should not incurrisk of serious injury from the airbags.
SIDE AIRBAGS
WARNINGS
Do not place objects or mountequipment on or near the airbagcover, on the side of the seatbacks(of the front seats), or in front seat areasthat may come into contact with adeploying airbag. Failure to follow theseinstructions may increase the risk ofpersonal injury in the event of a crash.
Do not use accessory seat covers.The use of accessory seat coversmay prevent the deployment of theside airbags and increase the risk of injuryin an accident.
Do not lean your head on the door.The side airbag could injure you as itdeploys from the side of theseatback.
Do not attempt to service, repair, ormodify the airbag, its fuses or theseat cover on a seat containing anairbag as you could be seriously injured orkilled. Contact your authorized dealer assoon as possible.
If the side airbag has deployed, theairbag will not function again. Theside airbag system (including theseat) must be inspected and serviced byan authorized dealer. If the airbag is notreplaced, the unrepaired area will increasethe risk of injury in a crash.

Supplementary Restraints SystemE142846

The side airbags are located on theoutboard side of the seatbacks of the frontseats. In certain sideways crashes, theairbag on the side affected by the crashwill be inflated. The airbag was designedto inflate between the door panel andoccupant to further enhance the protectionprovided occupants in side impact crashes.
The system consists of the following:
•A label or embossed side panelindicating that side airbags are foundon your vehicle.
•Side airbags located inside theseatback of the driver and frontpassenger seats.
·Crash sensors and monitoringsystem with readiness indicator.See Crash Sensors and AirbagIndicator (page 52).
The design and development of the sideairbag system included recommendedtesting procedures that were developedby a group of automotive safety expertsknown as the Side Airbag TechnicalWorking Group. These recommendedtesting procedures help reduce the risk ofinjuries related to the deployment of sideairbags.
SAFETY CANOPY™
WARNINGS
Do not place objects or mountequipment on or near the headlinerat the siderail that may come intocontact with a deploying curtain airbag.Failure to follow these instructions mayincrease the risk of personal injury in theevent of a crash.
Do not lean your head on the door.The curtain airbag could injure youas it deploys from the headliner.
Do not attempt to service, repair, ormodify the curtain airbagsupplemental restraint system, itsfuses, the A, B, or C pillar trim, or theheadliner on a vehicle containing curtainairbags as you could be seriously injuredor killed. Contact your authorized dealeras soon as possible.
All occupants of your vehicle,including the driver, should alwaysproperly wear their seatbelts, evenwhen an airbag supplemental restraintsystem is provided. Failure to properly wearyour seatbelt could seriously increase therisk of injury or death.
To reduce risk of injury, do notobstruct or place objects in thedeployment path of the airbag.
If the curtain airbags have deployed,the curtain airbags will not functionagain. The curtain airbags (includingthe A, B and C pillar trim and headliner)must be inspected and serviced as soonas possible. If the curtain airbag is notreplaced, the unrepaired area will increasethe risk of injury in a crash.

TOWING A TRAILER
WARNINGS
Towing trailers beyond themaximum recommendedgross trailer weight exceeds thelimit of your vehicle and couldresult in engine damage,transmission damage, structuraldamage, loss of vehicle control,vehicle rollover and personalinjury.
Do not exceed the GVWR orthe GAWR specified on thecertification label.
Note: See RecommendedTowing Weights (page 277).
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See Fuses(page 312).
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle or trailer.
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 ball mount with thecorrect rise or drop and loadcapacity. When both theloaded vehicle and trailer areconnected, 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 (page261).
You can also find information inthe RV & Trailer Towing Guideavailable at your authorizeddealer, or online.

•Federal and some local regulationsrequire additional exterior lamps forsnowplow-equipped vehicles. Consultyour authorized dealer for additionalinformation.
Operating the Vehicle with theSnowplow Attached
Note:Do not use your vehicle for snowremoval until you have driven at least500 mi (800 km).
Ford recommends vehicle speed does notexceed 45 mph (72 km/h) whensnowplowing.
The attached snowplow blade restrictsairflow to the radiator, and may cause theengine to run at a higher temperature:Attention to engine temperature isespecially important when outsidetemperatures are above freezing. Anglethe blade to maximize airflow to theradiator and monitor engine temperatureto determine whether a left or right angleprovides the best performance.
Follow the severe duty schedule in yourScheduled Maintenance information forengine oil and transmission fluid changeintervals.
Snowplowing with your AirbagEquipped Vehicle
WARNINGS
Do not attempt to service, repair, ormodify the airbag supplementalrestraint system (SRS) or its fuses.Contact an authorized dealer.
Additional equipment for examplesnowplow 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 seatbelt, 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 theairbags. 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.
