Pregnant women should always wear theirseatbelt. Position the lap belt portion of acombination lap and shoulder belt low acrossthe hips below the belly and worn as tightas comfort allows. Position the shoulder beltto cross the middle of the shoulder and thecenter of the chest.
Seatbelt Locking Modes
WARNING: If your vehicle is involvedin a crash, have the seatbelts and associatedcomponents inspected as soon as possible.Failure to follow this instruction could resultin personal injury or death.
All safety restraints in the vehicle arecombination lap and shoulder belts. Thedriver seatbelt has the vehicle sensitivelocking mode. The front outboard passengerand rear seatbelts have both the vehiclesensitive locking mode and the automaticlocking mode.
Vehicle Sensitive Mode
This is the normal retractor mode, whichallows free shoulder belt length adjustmentto your movements and locking in responseto vehicle movement. For example, if thedriver brakes suddenly or turns a cornersharply, or the vehicle receives an impact ofabout 5 mph (8 km/h) or more, thecombination seatbelts lock to help reduceforward movement of the driver andpassengers.
In addition, the retractor is designed to lockif you pull the webbing out too quickly. If theseatbelt retractor locks, slowly lower theheight adjuster to allow the seatbelt toretract. If the retractor does not unlock, pullthe seatbelt out slowly then feed a small
length of webbing back toward the stowedposition. For rear seatbelts, recline the rearseat backrest or push the seat backrestcushion away from the seatbelt. Feed a smalllength of webbing back toward the stowedposition.
Automatic Locking Mode
In this mode, the shoulder belt automaticallypre-locks. The belt retracts to remove anyslack in the shoulder belt. The automaticlocking mode is not available on the driverseatbelt.
When to Use the Automatic Locking Mode
Use this mode any time a child safety seat,except a booster, is installed in passengerfront or rear seating positions. Properlyrestrain children 12 years old and under in arear seating position whenever possible.See Child Safety (page 19).

1.Buckle the combination lap and shoulderbelt.
2. Grasp the shoulder portion and pulldownward until you pull the entire beltout. As the belt retracts, you will hear aclicking sound. This indicates the seatbeltis now in the automatic locking mode.
Rear outboard inflatable seatbelts (secondrow only–if equipped)
1.Buckle the combination lap and shoulderbelt.
2.Grasp the lap portion of the belt and pullupward until you pull the entire belt out.
3. Allow the belt to retract. As the beltretracts, you will hear a clicking sound.This indicates the seatbelt is now in theautomatic locking mode.
How to Disengage the Automatic LockingMode
Unbuckle the combination lap and shoulderbelt and allow it to retract completely todisengage the automatic locking mode andactivate the vehicle sensitive (emergency)locking mode.
Rear Inflatable Seatbelt (If Equipped)
WARNING: Do not attempt to service,repair, or modify the supplementary restraintsystem or associated components. Failureto follow this instruction could result inpersonal injury or death.
WARNING: If a supplementary restraintsystem component has deployed, it will notfunction again. Have the system andassociated components inspected as soonas possible. Failure to follow this instructioncould result in personal injury or death.
The rear inflatable seatbelts are in theshoulder portion of the seatbelts of thesecond-row outboard seating positions.

SeatbeltsE142591 E146363

Note:The rear inflatable seatbelts arecompatible with most infant and child safetycar seats and belt positioning booster seatswhen properly installed. This is because theyare designed to fill with a cooled gas at alower pressure and at a slower rate thantraditional airbags. After inflation, theshoulder portion of the seatbelt remains coolto the touch.
The rear inflatable seatbelt consists of thefollowing:
•An inflatable bag in the shoulder seatbeltwebbing.
•Lap seatbelt webbing with automaticlocking mode.
•The same warning light, electroniccontrol and diagnostic unit as used forthe front seatbelts.
•Impact sensors in various parts of thevehicle.
How does the rear inflatable seatbeltsystem work?
The rear inflatable seatbelts function likestandard restraints in everyday usage.
During a crash of sufficient force, theinflatable belt inflates from inside thewebbing.
The fully inflated belt's increased diametermore effectively holds the occupant in theappropriate seating position, and spreadscrash forces over more area of the body thanregular seatbelts. This helps reduce pressureon the chest and helps control head andneck motion for passengers.
The rear inflatable seatbelts are designed toinflate in frontal or near-frontal crashes andin some side impact crashes and rollovercrashes. The fact that the rear inflatableseatbelt did not inflate in a crash does notmean that something is wrong with thesystem. Rather, it means the forces were notof the type sufficient to cause activation.
SEATBELT HEIGHT ADJUSTMENT
WARNING: Position the safety beltheight adjusters so that the belt rests acrossthe middle of your shoulder. Failure to adjustthe safety belt properly could reduce theeffectiveness of the safety belt and increasethe risk of injury in a crash.

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 is
unbuckled.
The system uses information from the frontpassenger sensing system to determine if afront seat passenger is present and thereforepotentially in need of a warning. To avoidactivating the Belt-Minder feature for objectsyou place in the front passenger seat, onlythe front seat passengers receive warningsas determined by the front passengersensing system.
If the Belt-Minder warnings expire (warningsfor about five minutes) for one passenger(driver or front passenger), the otherpassenger can still cause the Belt-Minderfeature to turn on.

Seatbelts

We recommend that all seatbelt assembliesin use in vehicles involved in a crash bereplaced. However, if the crash was minorand an authorized dealer finds that the beltsdo not show damage and continue tooperate properly, they do not need to bereplaced. Seatbelt assemblies not in useduring a crash should also be inspected andreplaced if either damage or improperoperation is noted.
Properly care for seatbelts. See Cleaningthe Interior (page 323).
SEATBELT EXTENSION
WARNING: Persons who fit into thevehicle's seatbelt should not use anextension. Unnecessary use could result inserious personal injury in the event of acrash.
WARNING: Only use extensionsprovided free of charge by Lincoln MotorCompany dealers. The dealer will providean extension designed specifically for thisvehicle, model year and seating position. Theuse of an extension intended for anothervehicle, model year or seating position maynot offer you the full protection of yourvehicle’s seatbelt restraint system.
WARNING: Never use seatbeltextensions to install child restraints.
WARNING: Do not use a seatbeltextension with an inflatable seatbelt.
WARNING: Do not use extensions tochange the fit of the belt across the torso,over the lap or to make the seatbelt buckleeasier to reach.
If, because of body size or driving position,it is not possible to properly fasten theseatbelt over your lap and shoulder, anextension that is compatible with theseatbelts is available free of charge fromLincoln Motor Company dealers. Only Lincolnseatbelt extensions made by the samecompany which made the original equipmentseatbelts, should be used with Lincolnseatbelts.

Seatbelts

The Personal Safety System provides animproved overall level of frontal crashprotection to front seat occupants and isdesigned to help further reduce the risk ofairbag-related injuries. The system is able toanalyze different occupant conditions andcrash severity before activating theappropriate safety devices to help betterprotect a range of occupants in a variety offrontal crash situations.
The Vehicle Personal Safety System consistsof:
•Driver and passenger dual-stage airbagsupplemental restraints.
•Front seat outermost seatbelts withpretensioners, energy managementretractors and seatbelt usage sensors.
•Driver seat position sensor.
•Passenger seat position sensor.
•Front passenger sensing system.
•Passenger airbag off and on indicators.
•Front crash severity sensors.
•Restraints control module with impactand safing sensors.
•Restraint system warning lamp and tone.
•The electrical wiring for the airbags, crashsensors, seatbelt pretensioners, frontseatbelt usage sensors, driver seatposition sensor, front passenger sensingsystem and indicators.
How Does the Personal Safety SystemWork?
The Personal Safety System can adapt thedeployment strategy of the safety devicesaccording to crash severity and occupantconditions. A collection of crash andoccupant sensors provides information tothe restraints control module. During a crash,the restraints control module may deploy theseatbelt pretensioners, one or both stagesof the dual-stage airbags based on crashseverity and occupant conditions.

Personal Safety System™

PRINCIPLE OF OPERATION
WARNING: Airbags do not inflateslowly or gently, and the risk of injury from adeploying airbag is the greatest close to thetrim covering the airbag module.
WARNING: All occupants of yourvehicle, including the driver, should alwaysproperly wear their seatbelts, even when anairbag supplemental restraint system isprovided. Failure to properly wear yourseatbelt could seriously increase the risk ofinjury or death.
WARNING: Even with advancedrestraints systems, properly restrain children12 and under in a rear seating position.Failure to follow this could seriously increasethe risk of injury or death.
WARNING: Do not place your arms onthe airbag cover or through the steeringwheel. Failure to follow this instruction couldresult in personal injury.
WARNING: Keep the areas in front ofthe airbags free from obstruction. Do not affixanything to or over the airbag covers.Objects could become projectiles duringairbag deployment or in a sudden stop.Failure to follow this instruction could resultin personal injury or death.
WARNING: Airbags can kill or injure achild in a child restraint. Never place arear-facing child restraint in front of an activeairbag. If you must use a forward-facing childrestraint in the front seat, move the seat uponwhich the child restraint is installed all theway back.
WARNING: Do not attempt to service,repair, or modify the supplementary restraintsystem or associated components. Failureto follow this instruction could result inpersonal injury or death.
WARNING: Several airbag systemcomponents get hot after inflation. To reducethe risk of injury, do not touch them afterinflation.
WARNING: If a supplementary restraintsystem component has deployed, it will notfunction again. Have the system andassociated components inspected as soonas possible. Failure to follow this instructioncould result in personal injury or death.
The airbags are a supplemental restraintsystem and are designed to work with theseatbelts to help protect the driver and rightfront passenger from certain upper bodyinjuries. Airbags do not inflate slowly; thereis a risk of injury from a deploying airbag.
Note:You will hear a loud bang and see acloud of harmless powdery residue if anairbag deploys. This is normal.
