SEATBELT REMINDER
Belt-Minder™
This feature supplements the safety beltwarning function by providing additionalreminders that intermittently sound a toneand illuminate the safety belt warning lightwhen you are in the driver seat or you havea front seat passenger and a safety belt isunbuckled.
The system uses information from thefront passenger sensing system todetermine if a front seat passenger ispresent and therefore potentially in needof a warning. To avoid activating theBelt-Minder feature for objects you placein the front passenger seat, only the frontseat passengers receive warnings asdetermined by the front passenger sensingsystem.
If the Belt-Minder warnings expire(warnings for about five minutes) for onepassenger (driver or front passenger), theother passenger can still cause theBelt-Minder feature to turn on.

CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle seatbelts and childsafety seat systems periodically to makesure they work properly and are notdamaged. Inspect the vehicle and childrestraint seatbelts to make sure there areno nicks, tears or cuts. Replace ifnecessary. All vehicle seatbelt assemblies,including retractors, buckles, front seatbeltbuckle assemblies, buckle supportassemblies (slide bar-if equipped),shoulder belt height adjusters (ifequipped), shoulder belt guide on seatbackrest (if equipped), child safety seatLATCH and tether anchors, and attachinghardware, should be inspected after acrash. Read the child restraintmanufacturer's instructions for additionalinspection and maintenance informationspecific to the child restraint.
We recommend that all seatbeltassemblies in use in vehicles involved in acrash be replaced. However, if the crashwas minor and an authorized dealer findsthat the belts do not show damage andcontinue to operate properly, they do notneed to be replaced. Seatbelt assembliesnot in use during a crash should also beinspected and replaced if either damageor improper operation is noted.
Properly care for seatbelts. See VehicleCare (page 262).
SEATBELT EXTENSIONS
WARNING: Persons who fit intothe vehicle's seatbelt should not use anextension. Unnecessary use could resultin serious personal injury in the event ofa crash.
WARNING: Only use extensionsprovided free of charge by our dealers.The dealer will provide an extensiondesigned specifically for this vehicle,model year and seating position. The useof an extension intended for anothervehicle, model year or seating positionmay not offer you the full protection ofyour vehicle's seatbelt restraint system.
WARNING: Never use seatbeltextensions to install child restraints.
WARNING: Do not use extensionsto change the way the seatbelt fitsacross the torso, over the lap or to makethe seatbelt buckle easier to reach.

AIR SUSPENSION
Note:Do not operate your vehicle withoutair in the suspension springs. Operating yourvehicle without air in the suspension springsdamages the suspension, degrades rideperformance and may cause propertydamage.
The air suspension system automaticallyadjusts to different loads to maintain aconstant frame height, allows for ease ofvehicle loading, provides improved vehicleride, and increased driver comfort.
Air Suspension Dump Button
Note:The suspension dumps air when theignition is in the accessory or on position,but fills only when the ignition is in the onposition.
A button located on the instrument panelcontrols the system. It operates only whenthe ignition is in the accessory or onposition and the air tanks have sufficientpressure to fill the air springs. When youturn off the ignition, the suspensionremains in whatever state it was last set.
Pressing and holding the button for twoseconds exhausts air from the air springs,lowering the frame for loading. Pressingand holding the button for two secondsfills the air springs so your vehicle remainsat normal ride height.
System Indicator Light
The air suspension indicator lightilluminates when using the button torelease air pressure in the rear air springs.Never drive your vehicle when the warninglamp is illuminated and there is low (or no)air pressure in the springs.
Connecting and Disconnecting aTrailer with Air Suspension and AirSuspension Dump Button
When connecting to a trailer:
•Press and hold the button for twoseconds to exhaust air from the airsuspension system.
•Press and hold the button for twoseconds, and then raise the landinggear after making the connection tothe trailer.
When disconnecting the trailer:
•Lower the landing gear, and then pressand hold the button for two seconds.
•Disconnect the brake hoses, trailer-sideand rear light connectors, then pull therelease lever on the fifth wheel.
You must fill the air springs beforeoperating with a trailer or operating in thebobtail mode.
Suspension Conversions
WARNING: When operating aloaded vehicle, the driver must keep alladjustable axles on the ground at alltimes, supporting their share of thevehicle’s load.

the driver that battery protection actionsare active. These messages are only fornotification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
Electrical accessory installation
To ensure proper operation of the BMS,any electrical devices that are added tothe vehicle should not have their groundconnection made directly at the negativebattery post. A connection at the negativebattery post can cause inaccuratemeasurements of the battery conditionand potential incorrect system operation.
Note:Electrical or electronic accessoriesadded to the vehicle by the dealer or theowner may adversely affect batteryperformance and durability, and may alsoaffect the performance of other electricalsystems in the vehicle.
When a battery replacement is required,the battery should only be replaced witha Ford recommended replacement batterywhich matches the electrical requirementsof the vehicle. After battery replacement,or in some cases after charging the batterywith the external charger, the BMS requireseight hours of vehicle sleep time (key offwith doors closed) to relearn the newbattery state of charge. Prior to relearningthe state of charge, the BMS may disableelectrical features (to protect the battery)earlier than normal.

•Maintaining proper steering gear andpower steering pump lubricant levels.
•Checking steering column joint boltsand steering linkage, particularly forbody-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, checksteering column joint bolt tightness every60,000 mi (96,000 km) or annually,whichever occurs first. Do not overtightenthe bolts.
Hydraulic System
Whenever draining and refilling the powersteering's hydraulic system for any reason,bleed air from the system before returningthe vehicle to service. Failure to bleed thehydraulic system properly can result indegradation of power system performance.
Consult an authorized dealer who is awareof the proper procedures for filling andbleeding the system.
SUSPENSION SYSTEM
INSPECTION (IF EQUIPPED)
Note:Do not adjust air suspension heightto any setting other than the specifiedsetting. Altering the height setting changesthe driveline angle and may result inunwarrantable component damage, suchas transmission component damage.
Verify drive axle air suspension height andheight control valve performance at engineoil change intervals.
Periodically check:
•Condition of spring leaves for evidenceof fatigue, bending or breakage.
•Condition of suspension mountingbrackets and bushings.
•Torque rod mounting fasteners fortightness.
•For proper suspension alignment.Maintain proper alignment at all times.
•U-bolts. After the chassis has beenoperating under load for 1,000 mi(1,600 km) or six months (whichevercomes first), the U-bolt nuts must bere-torqued. Re-torque the U-bolt nutsevery 37,000 mi (60,000 km)thereafter. Clean and lubricate theU-bolt and nut threads and seats tomake sure a like new condition whenre-torqueing. See Spring U-BoltCheck (page 261).
