airbag LINCOLN MKX 2011 User Guide

WARNING:Always transport children 12 years old and under in
the back seat and always properly use appropriate child
restraints.
The front passenger sensing system can automatically turn off the front
passenger airbag and passenger seat-mounted side airbag. The system is
designed to help protect small (child size) occupants from frontal airbag
deployments when they are seated or restrained in the front passenger
seat contrary to proper child-seating or restraint usage
recommendations. Even with this technology, parents areSTRONGLY
encouraged to always properly restrain children in the rear seat. The
sensor also turns off the passenger front airbag and passenger
seat-mounted side airbag when the passenger seat is empty and the
safety belt is unbuckled.
Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety System to tailor the airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions, and in rollover and side collisions when the
Safety Canopyis activated. This helps increase the effectiveness of the
safety belts. In frontal collisions, the safety belt pretensioners can be
activated alone or, if the collision is of sufficient severity, together with
the front airbags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer toEnergy management feature
— front outboardsection in this chapter.
Determining if the Personal Safety System is operational
The Personal Safety System uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lights and chimessection in theInstrument Cluster
chapter. Routine maintenance of the Personal Safety System is not
required.

The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and front passenger sensing system. In addition, the
RCM also monitors the restraints warning light in the instrument cluster.
A difficulty with the system is indicated by one or more of the following.
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Safety belt precautions
WARNING:Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING:To reduce the risk of injury, make sure children sit
where they can be properly restrained.
WARNING:Never let a passenger hold a child on his or her lap
while the vehicle is moving. The passenger cannot protect the
child from injury in a collision.
WARNING:All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an air
bag supplemental restraint system (SRS) is provided.
WARNING:It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people riding in
these areas are more likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle that is not equipped
with seats and safety belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.

How to disengage the automatic locking mode
Disconnect the combination lap/shoulder belt and allow it to retract
completely to disengage the automatic locking mode and activate the
vehicle sensitive (emergency) locking mode.
WARNING:After any vehicle collision, the safety belt system at
all passenger seating positions must be checked by an authorized
dealer to verify that the “automatic locking retractor” feature for child
seats is still functioning properly. In addition, all safety belts should be
checked for proper function.
WARNING:BELT AND RETRACTOR ASSEMBLY MUST BE
REPLACED if the safety belt assembly “automatic locking
retractor” feature or any other safety belt function is not operating
properly when checked by an authorized dealer. Failure to replace the
belt and retractor assembly could increase the risk of injury in
collisions.
Energy management feature — front outboard
•This vehicle has a safety belt system with an energy management
feature at the front seats to help further reduce the risk of injury in
the event of a head-on collision.
•The energy management feature has a retractor assembly that is
designed to extend the safety belt webbing in a controlled manner.
This helps reduce the belt force acting on the user’s chest.
WARNING:Failure to inspect and replace if necessary the belt
and retractor assembly after an accident could increase the risk
of injury in a collision.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
front outboard passenger seating positions.
The safety belt pretensioner tightens the safety belts firmly against the
occupant’s body at the start of the crash.
WARNING:The driver and front passenger safety belt system
(including retractors, buckles and height adjusters) must be
replaced if the vehicle is involved in a collision that results in
deployment of front airbags, seat-mounted side airbags and Safety
CanopySystem and safety belt pretensioners.

The following are reasons most often given for not wearing safety belts
(All statistics based on U.S. data):
Reasons given... Consider...
“Crashes are rare
events”36700 crashes occur every day.The more we
drive, the more we are exposed to “rare” events,
even for good drivers.1 in 4 of us will be seriously
injured in a crash during our lifetime.
“I’m not going
far”3of4fatal crashes occur within25miles (40 km)
of home.
“Belts are
uncomfortable”We design our safety belts to enhance comfort. If
you are uncomfortable - try different positions for
the safety belt upper anchorage and seatback which
should be as upright as possible; this can improve
comfort.
“I was in a hurry”Prime time for an accident.Belt-Minderreminds
us to take a few seconds to buckle up.
“Safety belts
don’t work”Safety belts,when used properly,reduce risk of
deathto front seat occupants by45% in cars,and
by60% in light trucks.
“Traffic is light”Nearly 1 of 2 deaths occur in single-vehicle
crashes,many when no other vehicles are around.
“Belts wrinkle
my clothes”
Possibly, but a serious crash can do much more than
wrinkle your clothes, particularly if you are unbelted.
“The people I’m
with don’t wear
belts”Set the example, teen deaths occur 4 times more
often in vehicles with TWO or MORE people.
Children and younger brothers/sisters imitate
behavior they see.
“I have an
airbag”Airbags offer greater protection when used with
safety belts. Frontal airbags are not designed to
inflate in rear and side crashes or rollovers.
“I’d rather be
thrown clear”Not a good idea.Peoplewho areejected are 40
times more likely to DIE.Safety belts help
prevent ejection, WE CAN’T “PICK OUR CRASH”.
WARNING:Do not sit on top of a buckled safety belt or insert a
latchplate into the buckle to avoid the Belt-Minderchime. To
do so may adversely affect the performance of the vehicle’s airbag
system.

3. For the seating position being disabled, buckle then unbuckle the
safety belt three times at a moderate speed, ending in the unbuckled
state.
•After Step 3, the safety belt warning light will be turned on for three
seconds.
4. Within approximately seven seconds of the light turning off, buckle
then unbuckle the safety belt.
•This will disable the Belt-Minderfeature for that seating position if it
is currently enabled. As confirmation, the safety belt warning light will
flash 12 times in three seconds.
•This will enable the Belt-Minderfeature for that seating position if it

Important supplemental restraint system precautions
Airbags DO NOT inflate slowly or
gently and the risk of injury from a
deploying airbag is greatest close to
the trim covering the airbag module.
WARNING:All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an air
bag supplemental restraint system (SRS) is provided.
WARNING:When possible, all children 12 years old and under
should be properly restrained in a rear seating position.
WARNING:National Highway Traffic Safety Administration
(NHTSA) recommends a minimum distance of at least 10 inches
(25 cm) between an occupant’s chest and the driver airbag module.
WARNING:Never place your arm over the airbag module as a
deploying airbag can result in serious arm fractures or other
injuries.
Steps you can take to properly position yourself away from the airbag:
•Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
•Recline the seat slightly (one or two degrees) from the upright
position.

WARNING:Do not put anything on or over the airbag module.
Placing objects on or over the airbag inflation area may cause
those objects to be propelled by the airbag into your face and torso
causing serious injury.
WARNING:Do not attempt to service, repair, or modify the
airbag supplemental restraint system (SRS) or its fuses. See your
authorized dealer.
WARNING:Modifying or adding equipment to the front end of
the vehicle (including frame, bumper, front end body structure
and tow hooks) may affect the performance of the airbag system,
increasing the risk of injury. Do not modify the front end of the
vehicle.
Children and airbags
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear
seating positions than in the front
seating position. Failure to follow
these instructions may increase the
risk of injury in a collision.
WARNING:Airbags can kill
or injure a child in a child
seat.NEVERplace a rear-facing
child seat in front of an active
airbag. If you must use a
forward-facing child seat in the
front seat, move the seat all the
way back.

How does the safety belt pretensioner and airbag supplemental
restraint system work?
The safety belt pretensioner and
airbag SRS are designed to activate
when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates
pretensioner activation and airbag
inflation.
The fact that the airbags did not
activate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces were not of the type sufficient to
cause activation. Front airbags are designed to activate in frontal and
near-frontal collisions, not rollover, side-impact, or rear-impacts unless
the collision causes sufficient longitudinal deceleration.
The airbags inflate and deflate
rapidly upon activation. After airbag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
airbag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with
a deploying airbag may also cause abrasions, swelling or temporary
hearing loss. Because airbags must inflate rapidly and with considerable
force, there is the risk of death or serious injuries such as fractures,
facial and eye injuries or internal injuries, particularly to occupants who
are not properly restrained or are otherwise out of position at the time
of airbag deployment. Thus, it is extremely important that occupants be
properly restrained as far away from the airbag module as possible while
maintaining vehicle control.

WARNING:Several air bag system components get hot after
inflation. Do not touch them after inflation.
WARNING:If the air bag has deployed,the air bag will not
function again and must be replaced immediately.If the air
bag is not replaced, the unrepaired area will increase the risk of injury
in a collision.
The SRS consists of:
•driver and passenger airbag modules (which include the inflators and
airbags)
•seat-mounted side airbags. Refer toSeat-mounted side airbag system
later in this chapter
•safety belt pretensioners
•one or more impact and safing sensors
•a readiness light and tone
•and the electrical wiring which connects the components
•Side curtain airbag system. Refer toSafety CanopySystemlater in
this chapter.
•Front passenger sensing system. Refer toFront passenger sensing
systemlater in this chapter.
•“Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing systemlater in this chapter.
The diagnostic module monitors its own internal circuits and the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
backup power, the airbag ignitors and safety belt pretensioners.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.
The front passenger sensing system works with sensors that are part of
the front passenger’s seat and safety belt. The sensors are designed to
detect the presence of a properly seated occupant and determine if the
front passenger’s frontal airbag should be enabled (may inflate) or
disabled (will not inflate).

The front passenger sensing system will disable (will not inflate) the
front passenger’s frontal airbag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat.
•the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer’s instructions.
•the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions.
•the system determines that a small child is present in a booster seat.
•a front passenger takes his/her weight off of the seat for a period of
time.
Passenger airbag status indicator
The front passenger sensing system
uses a passenger airbag status
indicator which will illuminate
indicating that the front passenger
frontal airbag is either ON (enabled)
or OFF (disabled). The indicator
lamp is located in the center stack
of the instrument panel.
Note:The passenger airbag status indicator OFF and ON lamps will
illuminate for a short period of time when the ignition is first turned on
to confirm it is functional.
The front passenger sensing system is designed to disable (will not
inflate) the front passenger’s frontal airbag when the front passenger
seat is unoccupied, or a rear facing infant seat, a forward-facing child
restraint, or a booster seat is detected.
•When the front passenger sensing system disables (will not inflate)
the front passenger frontal airbag, the passenger airbag status
indicator will illuminate the OFF lamp and stay lit to remind you that
the front passenger frontal airbag is disabled.
•If the child restraint has been installed and the passenger airbag
status indicator illuminates the ON lamp, then turn the vehicle off,
remove the child restraint from the vehicle and reinstall the restraint
following the child restraint manufacturer’s instructions.
The front passenger sensing system is designed to enable (may inflate)
the front passenger’s frontal airbag anytime the system senses that a
person of adult size is sitting properly in the front passenger seat.
