After all occupants have adjusted their seatsand put on seatbelts, it is very important thatthey continue to sit properly. A properlyseated occupant sits upright, leaning againstthe seat backrest, and centered on the seatcushion, with their feet comfortably extendedon the floor. Sitting improperly can increasethe chance of injury in a crash event. Forexample, if an occupant slouches, lies down,turns sideways, sits forward, leans forwardor sideways, or puts one or both feet up, thechance of injury during a crash greatlyincreases.
The conditions listed above may cause theweight of a properly seated occupant to beincorrectly interpreted by the front passengersensing system. The person in the frontpassenger seat may appear heavier or lighterdue to the conditions described in the listabove.
Make sure the front passengersensing system is operatingproperly. See Crash Sensors andAirbag Indicator (page 55).
Do not attempt to repair or service thesystem. Take your vehicle immediately to anauthorized dealer.
If it is necessary to modify an advanced frontairbag system to accommodate a personwith disabilities, contact the Ford CustomerRelationship Center. See Getting theServices You Need (page 269).
SIDE AIRBAGS
WARNING: Do not place objects ormount equipment on or near the airbagcover, on the side of the front or rearseatbacks, or in areas that may come intocontact with a deploying airbag. Failure tofollow these instructions may increase therisk of personal injury in the event of a crash.
WARNING: Do not use accessory seatcovers. The use of accessory seat coversmay prevent the deployment of the sideairbags and increase the risk of injury in anaccident.
WARNING: Do not lean your head onthe door. The side airbag could injure youas it deploys from the side of the seatback.
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 side airbags are on the outboard sideof the seat backrests of the front seats. Incertain sideways crashes, the side airbagswill be inflated. The airbag was designed toinflate between the door panel and occupantto further enhance the protection providedoccupants in side impact crashes.

Supplementary Restraints SystemE67017

The system consists of the following:
•A label or embossed side panelindicating that side airbags are fitted toyour vehicle.
•Side airbags inside the driver and frontpassenger seat backrests.
•Front passenger sensing system.
•Crash sensors and monitoring systemwith readiness indicator. See CrashSensors and Airbag Indicator (page 55).
The design and development of the sideairbag system included recommendedtesting procedures that were developed bya group of automotive safety experts knownas the Side Airbag Technical Working Group.These recommended testing procedureshelp reduce the risk of injuries related to thedeployment of side airbags.
DRIVER AND PASSENGER KNEE
AIRBAGS
Driver and passenger knee airbags arelocated under or within the instrument panel.During a crash, the restraints control modulemay activate the driver and passenger kneeairbags (individually or both) based on crashseverity and respective occupant conditions.Under certain crash and occupant conditions,the driver and passenger knee airbags maydeploy (individually or both) but thecorresponding front airbag may not activate.As with front and side airbags, it is importantto be properly seated and restrained toreduce the risk of death or serious injury.
Make sure the knee airbags areoperating properly. See CrashSensors and Airbag Indicator(page 55).
SAFETY CANOPY™
WARNING: Do not place objects ormount equipment on or near the headlinerat the siderail that may come into contactwith a deploying curtain airbag. Failure tofollow these instructions may increase therisk of personal injury in the event of a crash.
WARNING: Do not lean your head onthe door. The curtain airbag could injure youas it deploys from the headliner.
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.

CRASH SENSORS AND AIRBAG
INDICATOR
WARNING: Modifying or addingequipment to the front end of the vehicle(including frame, bumper, front end bodystructure and tow hooks) may affect theperformance of the airbag system, increasingthe risk of injury. Do not modify the front endof the vehicle.
Your vehicle has a collection of crash andoccupant sensors which provide informationto the restraints control module. Therestraints control module deploys (activates)the front seatbelt system, the adaptivecollapsible steering column, driver airbag,passenger airbag, knee airbag(s), seatmounted side airbags, Safety Canopy andoptional rear inflatable seatbelts. Based onthe type of crash, the restraints controlmodule will deploy the appropriate safetydevices.
The restraints control module also monitorsthe readiness of the above safety devicesplus the crash and occupant sensors. Thereadiness of the safety system is indicatedby a warning indicator light in the instrumentcluster or a backup tone (if equipped).Routine maintenance of the airbag is notrequired.
A difficulty with the system is indicated byone or more of the following:
The readiness light will notilluminate immediately after theignition is turned on.
•The readiness light will either flash orstay lit.
•A series of five beeps will be heard (Ifequipped). The tone pattern will repeatperiodically until the problem, the lightor both are repaired.
If any of these things happen, evenintermittently, have the supplementalrestraint system serviced at an authorizeddealer immediately. Unless serviced, thesystem may not function properly in theevent of a crash.
The seatbelt pretensioners and the frontairbag supplemental restraint system aredesigned to activate when the vehiclesustains frontal deceleration sufficient tocause the restraints control module to deploya safety device.
The fact that the seatbelt pretensioners orfront airbags did not activate for both frontseat occupants in a crash does not meanthat something is wrong with the system.Rather, it means the restraints control moduledetermined the accident conditions (crashseverity, belt usage) were not appropriate toactivate these safety devices.
•The design of the front airbags is toactivate only in frontal and near-frontalcrashes (not rollovers, side impacts orrear impacts) unless the crash causessufficient frontal deceleration.
•The seatbelt pretensioners and rearinflatable seatbelts are designed toactivate in frontal, near-frontal and sidecrashes and rollovers.
•The knee airbag(s) may deploy based oncrash severity and occupant conditions.

The scheduled maintenance items listed inscheduled maintenance information areessential to the life and performance of yourvehicle and to its emissions system.
If you use anything other than Lincoln,Motorcraft or Lincoln-authorized parts formaintenance replacements or for service ofcomponents affecting emission control, suchnon-Lincoln parts should be equivalent togenuine Lincoln Motor Company parts inperformance and durability.
Illumination of the service engine soonindicator, charging system warning light orthe temperature warning light, fluid leaks,strange odors, smoke or loss of enginepower could indicate that the emissioncontrol system is not working properly.
An improperly operating or damaged exhaustsystem may allow exhaust to enter thevehicle. Have a damaged or improperlyoperating exhaust system inspected andrepaired immediately.
Do not make any unauthorized changes toyour vehicle or engine. By law, vehicleowners and anyone who manufactures,repairs, services, sells, leases, tradesvehicles, or supervises a fleet of vehicles arenot permitted to intentionally remove anemission control device or prevent it fromworking. Information about your vehicle’semission system is on the Vehicle EmissionControl Information Decal located on or nearthe engine. This decal also lists enginedisplacement.
Please consult your warranty information forcomplete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects the environmentby making sure that your vehicle continuesto meet government emission standards. TheOBD-II system also assists a servicetechnician in properly servicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected a malfunction.Temporary malfunctions may cause theservice engine soon indicator to illuminate.Examples are:
1. Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in the fuel—theengine may misfire or run poorly.
3. The fuel fill inlet may not have closedproperly. See Refueling (page 169).
4. Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank with goodquality fuel, properly closing the fuel fill inletor letting the electrical system dry out. Afterthree driving cycles without these or anyother temporary malfunctions present, theservice engine soon indicator should stay offthe next time you start the engine. A drivingcycle consists of a cold engine startupfollowed by mixed city and highway driving.No additional vehicle service is required.

Engine Emission Control

If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II may nothave symptoms that are apparent, continueddriving with the service engine soon indicatoron can result in increased emissions, lowerfuel economy, reduced engine andtransmission smoothness and lead to morecostly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programs toinspect the emission control equipment onyour vehicle. Failure to pass this inspectioncould prevent you from getting a vehicleregistration.
If the service engine soon indicatoris on or the bulb does not work,your vehicle may need service.See On-Board Diagnostics.
Your vehicle may not pass the I/M test if theservice engine soon indicator is on or notworking properly (bulb is burned out), or ifthe OBD-II system has determined that someof the emission control systems have notbeen properly checked. In this case, thevehicle is not ready for I/M testing.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that the vehicleis not ready for I/M testing. To determine ifthe vehicle is ready for I/M testing, turn theignition key to the on position for 15 secondswithout cranking the engine. If the serviceengine soon indicator blinks eight times, itmeans that the vehicle is not ready for I/Mtesting; if the service engine soon indicatorstays on solid, it means that your vehicle isready for I/M testing.
The OBD-II system checks the emissioncontrol system during normal driving. Acomplete check may take several days.
If the vehicle is not ready for I/M testing, youcan perform the following driving cycleconsisting of mixed city and highway driving:
1. 15 minutes of steady driving on anexpressway or highway followed by 20minutes of stop-and-go driving with atleast four 30-second idle periods.
2.Allow your vehicle to sit for at least eighthours with the ignition off. Then, start thevehicle and complete the above drivingcycle. The vehicle must warm up to itsnormal operating temperature. Oncestarted, do not turn off the vehicle untilthe above driving cycle is complete.
If the vehicle is still not ready for I/M testing,you need to repeat the above driving cycle.
