FORD FOCUS 2018 Service Manual

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 seatbelts, evenwhen an airbag supplemental restraintsystem is provided. Failure to properly wearyour seatbelt could seriously increase therisk of injury or death.
Even with advanced restraintssystems, properly restrain children12 and under in a rear seatingposition. Failure to follow this couldseriously increase the risk of injury or death.
Do not place your arms on the airbagcover or through the steering wheel.Failure to follow this instructioncould result in personal injury.
Keep the areas in front of the airbagsfree 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 couldresult in personal injury or death.
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 childrestraint is installed all the way back.
Do not attempt to service, repair, ormodify the supplementary restraintsystem or associated components.Failure to follow this instruction couldresult in personal injury or death.
WARNINGS
Several airbag system componentsget hot after inflation. To reduce therisk of injury, do not touch them afterinflation.
If a supplementary restraint systemcomponent has deployed, it will notfunction again. Have the system andassociated components inspected as soonas possible. Failure to follow thisinstruction could result in personal injuryor death.
The airbags are a supplemental restraintsystem and are designed to work with theseatbelts 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.
DRIVER AND PASSENGER
AIRBAGS
WARNINGS
Do not place your arms on the airbagcover or through the steering wheel.Failure to follow this instructioncould result in personal injury.
Keep the areas in front of the airbagsfree 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 couldresult in personal injury or death.
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 childrestraint is installed all the way back.
The driver and front passenger airbags willdeploy during significant frontal and nearfrontal crashes.
The driver and passenger front airbagsystem consists of:
•Driver and passenger airbag modules.
•Front passenger sensing system.
· Crash sensors and monitoringsystem with readiness indicator.See Crash Sensors and AirbagIndicator (page 45).
Proper Driver and Front PassengerSeating Adjustment
WARNING
National Highway Traffic SafetyAdministration (NHTSA)recommends a minimum distanceof at least 10 in (25 cm) 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.
392018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingSupplementary Restraints SystemE151127 E67017

After all occupants have adjusted theirseats and put on seatbelts, it is veryimportant that they continue to sitproperly. A properly seated occupant sitsupright, leaning against the seatback, andcentered on the seat cushion, with theirfeet comfortably extended on the floor.Sitting improperly can increase the chanceof injury in a crash event. For example, ifan occupant slouches, lies down, turnssideways, sits forward, leans forward orsideways, or puts one or both feet up, thechance of injury during a crash is greatlyincreased.
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 childrestraint 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.
FRONT PASSENGER SENSING
SYSTEM
WARNINGS
Even with advanced restraintssystems, properly restrain children12 and under in a rear seatingposition. Failure to follow this couldseriously increase the risk of injury or death.
Sitting improperly, out of position orwith the seatback reclined too farcan take weight off the seat cushionand affect the decision of the passengersensing system, resulting in serious injuryor death in the event of a crash. Always situpright against your seat back, with yourfeet on the floor.
Do not stow objects in the seatbackmap pocket or hang objects off aseatback if a child is in the frontpassenger seat. Do not place objects underthe front passenger seat or between theseat and the center console. Check thepassenger airbag indicator lamp for properairbag status. Failure to follow theseinstructions may interfere with the frontpassenger seat sensing system andincrease the risk of serious injury.
Any alteration or modification to thefront passenger seat may affect theperformance of the front passengersensing system. This could seriouslyincrease the risk of injury or death.
This system works with sensors that arepart of the front passenger seat andseatbelt to detect the presence of aproperly-seated occupant and determineif the front passenger frontal airbag shouldbe enabled (may inflate) or not.
402018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingSupplementary Restraints SystemE142846

The front passenger sensing system usesa passenger airbag status indicator thatilluminates indicating that the frontpassenger frontal airbag is either ON(enabled) or OFF (disabled).
The indicator lamp is located in the centerstack of the instrument panel.
Note:The passenger airbag status indicatorOFF and ON indicator lamps illuminate fora short period of time when the ignition isfirst turned on to confirm they are functional.
The front passenger sensing system isdesigned to disable (will not inflate) thefront passenger frontal airbag when thefront passenger seat is unoccupied, or arear facing infant seat, a forward-facingchild restraint, or a booster seat isdetected. Even with this technology,parents are strongly encouraged toalways properly restrain children in the rearseat. The sensor also turns off thepassenger front airbag when the passengerseat is empty.
•When the front passenger sensingsystem disables (will not inflate) thefront passenger frontal airbag, thepassenger airbag status indicatorilluminates the OFF lamp and stays litto remind you that the front passengerfrontal airbag is disabled.
•If the child restraint has been installedand the passenger airbag statusindicator illuminates the ON lamp, thenturn the vehicle off, remove the childrestraint from the vehicle and reinstallthe restraint following the childrestraint manufacturer's instructions.
The front passenger sensing system isdesigned to enable (may inflate) the frontpassenger's frontal airbag anytime thesystem senses that a person of adult sizeis sitting properly in the front passengerseat.
•When the front passenger sensingsystem enables the front passengerfrontal airbag (may inflate), thepassenger airbag status indicatorilluminates the ON lamp and remainsilluminated.
If a person of adult size is sitting in the frontpassenger seat, but the airbag off indicatorlamp is lit, it is possible that the person isnot sitting properly in the seat. If thishappens:
•Turn the vehicle off and ask the personto place the seatback in the full uprightposition.
•Have the person sit upright in the seat,centered on the seat cushion, with theperson’s legs comfortably extended.
•Restart the vehicle and have the personremain in this position for about twominutes. This allows the system todetect that person and enable thepassenger’s frontal airbag.
•If the indicator OFF lamp remains liteven after this, the person should beadvised to ride in the rear seat.

After all occupants have adjusted theirseats and put on seatbelts, it is veryimportant that they continue to sitproperly. A properly seated occupant sitsupright, leaning against the seatback, andcentered on the seat cushion, with theirfeet comfortably extended on the floor.Sitting improperly can increase the chanceof injury in a crash event. For example, ifan occupant slouches, lies down, turnssideways, sits forward, leans forward orsideways, or puts one or both feet up, thechance of injury during a crash is greatlyincreased.
If you think that the status of the passengerairbag indicator lamp is incorrect, checkfor the following:
•Objects lodged underneath the seat.
•Objects between the seat cushion andthe center console.
•Objects hanging off the seatback.
•Objects stowed in the seatback mappocket.
•Objects placed on the occupant’s lap.
•Cargo interference with the seat.
•Other passengers pushing or pulling onthe seat.
•Rear passenger feet and knees restingor pushing on the seat.
The conditions listed above may cause theweight of a properly seated occupant tobe incorrectly interpreted by the frontpassenger sensing system. The person inthe front passenger seat may appearheavier or lighter due to the conditionsdescribed in the list above.
Make sure the front passengersensing system is operatingproperly, See Crash Sensorsand Airbag Indicator (page 45).
If the airbag readiness lamp is lit, dothe following:
The driver or adult passengers shouldcheck for any objects that may be lodgedunderneath the front passenger seat orcargo interfering with the seat.
If objects are lodged or cargo is interferingwith the seat, please take the followingsteps to remove the obstruction:
•Pull the vehicle over.
•Turn the vehicle off.
•Driver or adult passengers shouldcheck for any objects lodgedunderneath the front passenger seator cargo interfering with the seat.
•Remove the obstruction(s) (if found).
•Restart the vehicle.
422018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingSupplementary Restraints SystemE67017

•Wait at least two minutes and verifythat the airbag readiness lamp is nolonger illuminated
•If the airbag readiness lamp remainsilluminated, this may or may not be aproblem due to the front passengersensing system.
Do not attempt to repair or service thesystem. Take your vehicle immediately toan authorized dealer.

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 seat airbag supplementalrestraint systems, its fuses or theseat cover on a vehicle containing seatairbags as you could be seriously injuredor killed. Contact your authorized dealeras soon as possible.
WARNINGS
If the side airbag has deployed, theairbag will not function again. Theside airbag system (including theseat) must be inspected as soon aspossible. If the airbag is not replaced, theunrepaired area will increase the risk ofinjury in a crash.
The side airbags are on the outboard sideof the seatbacks of the front seats. Theairbag was designed to inflate betweenthe door panel and occupant to furtherenhance the protection provided tooccupants in certain side impact crashes.
The system consists of the following:
•A label or embossed side panelindicating that side airbags are fittedto your vehicle.
•Side airbags inside the driver and frontpassenger seatbacks.
•Front passenger sensing system.

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.
DRIVER KNEE AIRBAG
A driver's knee airbag is located under theinstrument panel. During a crash, therestraints control module may activate thedriver's knee airbag based on crash severityand occupant conditions. Under certaincrash and occupant conditions, the driver’sknee airbag may deploy but the driver’sfront airbag may not activate. As with frontand side airbags, it is important to beproperly seated and restrained to reducethe risk of death or serious injury.
Make sure the knee airbag isoperating properly. See CrashSensors and Airbag Indicator(page 45).
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.
WARNINGS
Do not attempt to service, repair, ormodify the supplementary restraintsystem or associated components.Failure to follow this instruction couldresult in personal injury or death.
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 a supplementary restraint systemcomponent has deployed, it will notfunction again. Have the system andassociated components inspected as soonas possible. Failure to follow thisinstruction could result in personal injuryor death.
The Safety Canopy deploys duringsignificant side crashes or when a certainlikelihood of a rollover event is detectedby the rollover sensor. The Safety Canopyis mounted to the roof side rail sheet metal,behind the headliner, above each row ofseats. In certain sideways crashes orrollover events, the Safety Canopy will beactivated, regardless of which seats areoccupied. The Safety Canopy is designedto inflate between the side window areaand occupants to further enhanceprotection provided in side impact crashesand rollover events.
442018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingSupplementary Restraints SystemE67017

The system consists of the following:
•Safety Canopy curtain airbags abovethe trim panels over the front and rearside windows identified by a label orwording on the headliner or roof-pillartrim.
•A flexible headliner which opens abovethe side doors to allow air curtaindeployment
· Crash sensors and monitoringsystem with a readinessindicator. See Crash Sensorsand Airbag Indicator (page 45).
Properly restrain children 12 years old andunder in the rear seats. The Safety Canopywill not interfere with children restrainedusing a properly installed child or boosterseat because it is designed to inflatedownward from the headliner above thedoors along the side window opening.
The design and development of the SafetyCanopy included recommended testingprocedures that were developed by agroup of automotive safety experts knownas the Side Airbag Technical WorkingGroup. These recommended testingprocedures help reduce the risk of injuriesrelated to the deployment of side airbags(including the Safety Canopy).
CRASH SENSORS AND
AIRBAG INDICATOR
WARNING
Modifying or adding equipment tothe front end of your vehicle(including hood, bumper system,frame, front end body structure, tow hooksand hood pins) may affect theperformance of the airbag system,increasing the risk of injury. Do not modifyor add equipment to the front end of yourvehicle.
Your vehicle has a collection of crash andoccupant sensors which provideinformation to the restraints controlmodule which deploys (activates) thefront seatbelt pretensioners, driver airbag,passenger airbag, knee airbag(s), seatmounted side airbags, and the SafetyCanopy. Based on the type of crash, therestraints control module will deploy theappropriate safety devices.
The restraints control module alsomonitors the readiness of the above safetydevices plus the crash and occupantsensors. A warning indicator light in theinstrument cluster indicates the readinessof the safety system. If this warningindicator light is not functioning and thereis another fault within the system, themessage cluster could display an airbagfailure warning. You could hear five tonesthat repeat periodically until you repair theproblem, the warning indicator light couldilluminate or both. Routine maintenanceof the airbag is not required.
A difficulty with the system is indicated byone or more of the following:
The indicator light will notilluminate immediately after theignition is turned on.
452018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingSupplementary Restraints SystemE75004 E67017 E67017

•The indicator light either flashes orstays illuminated.
•You could hear five tones thatperiodically repeat until the problem isrepaired.
•A message could appear in theinformation display.
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 airbagsupplemental restraint system aredesigned to activate when your vehiclesustains frontal or sideways decelerationsufficient to cause the restraints controlmodule to deploy a safety device or whena certain likelihood of a rollover event isdetected by the rollover sensor.
The fact that the seatbelt pretensionersor 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 controlmodule determined the crash conditions(for example, crash severity, belt usage)were not appropriate to activate thesesafety 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 aredesigned to activate in frontal,near-frontal, side and rollover crashes.
•The design of the side airbags is toinflate in certain side crashes. Sideairbags could activate in other types ofcrashes if the vehicle experiencessufficient sideways motion ordeformation.
•The knee airbag(s) could deploy basedon crash severity and occupantconditions.
•The design of the Safety Canopy is toinflate in certain side impact crashesand when a certain likelihood ofrollover is detected by the rolloversensor. The Safety Canopy couldactivate in other types of crashes if thevehicle experiences sufficient sidewaysmotion or deformation, or a certainlikelihood of rollover.
AIRBAG DISPOSAL
Contact your authorized dealer as soon aspossible. Airbags must be disposed of byqualified personnel.
