Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
right front passenger seating positions.
The safety belt pretensioner removes some slack from the safety belt
system at the start of a crash. The safety belt pretensioner uses the
same crash sensor system as the front airbags and Safety Canopy
System. When the safety belt pretensioner deploys, the lap and shoulder
belt are tightened.
When the Safety CanopySystem and/or the front airbags are activated,
the safety belt pretensioners for the driver and right front passenger
seating positions will be activated when the respective seatbelt is
properly buckled.
WARNING:The driver and the right 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 or Safety CanopySystem and safety belt
pretensioners.
WARNING:Failure to replace the safety belt assembly under
the above conditions could result in severe personal injuries in
the event of a collision.
Refer to theSafety belt maintenancesection in this chapter.
Safety belt usage sensors
The driver and front outboard passenger safety belt buckles are
equipped with sensors that detect if the safety belts are fastened. The
sensors provide information to the Personal Safety Systemwhich can
then adapt the airbag deployment or safety belt pretensioner activation
based upon safety belt usage.
WARNING:The Personal Safety Systemprovides the most
benefit to belted occupants. The system monitors and tailors the
airbag deployment based upon safety belt usage. Failure to properly
wear your safety belt will increase your risk of injury.

Safety belt extension assembly
If the safety belt is too short when fully extended, a safety belt extension
assembly can be obtained from an authorized dealer.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
WARNING:Do not use extensions to change the fit of the
shoulder belt across the torso.
AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The airbag supplemental restraint system is designed to work in
conjunction with the safety belts to help protect the driver and front
outboard passenger from certain upper body injuries. The term
“supplemental restraint” means the airbags are intended as a supplement
to the safety belts. Airbags alone cannot protect as well as airbags plus
safety belts in impacts for which the airbags are designed to deploy, and
airbags do not offer any protection in crashes for which they do not
deploy.
The airbag supplemental restraint system consists of:
•driver and passenger dual stage airbag modules (which include the
inflators and airbags).
•side airbags and Safety Canopy. Refer toSeat-mounted side airbag
systemandSafety Canopysystemlater in this chapter.
•one or more impact and safing sensors.

WARNING:Never place your arm over the airbag module as a
deploying airbag can result in serious arm fractures or other
injuries.
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 systems or its fuses. Contact your
authorized dealer as soon as possible.
WARNING:The front passenger airbag is not designed to offer
protection to an occupant in the center front seating position.
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.
WARNING:Additional equipment may affect the performance of
the airbag sensors increasing the risk of injury.

WARNING:Several airbag system components get hot after
inflation. Do not touch them after inflation.
WARNING:If the airbag has deployed,the airbag will not
function again and must be replaced immediately.If the
airbag is not replaced, the unrepaired area will increase the risk of
injury in a collision.
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,
•a child or a small person occupies the front passenger seat.
Note:When the passenger airbag off light is illuminated, the passenger
(seat mounted) side airbag may be disabled to avoid the risk of airbag
deployment injuries.

WARNING:All occupants of the vehicle should always wear
their safety belts even when an airbag SRS is provided.
How does the side airbag system work?
The design and development of the
side airbag system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags.
The side airbag system consists of
the following:
•An inflatable bag (airbag) with a gas generator concealed behind the
outboard bolster of the driver and front passenger seatbacks.
•A special seat cover designed to allow airbag deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Crash sensors located on the front doors.
•One crash sensor located on each side of the b-pillar, (SuperCab only).
•One crash sensor located on each side of the c-pillar, (SuperCrew
only).
Side airbags, in combination with safety belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side airbags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the airbag on the side affected by
the collision will be inflated. The airbag was designed to inflate between
the door panel and occupant to further enhance the protection provided
occupants in side impact collisions.
The airbag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates airbag inflation.

How does the Safety CanopySystem work?
The design and development of the
Safety Canopy system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy).
The Safety Canopy system consists
of the following:
•An inflatable curtain with a gas
generator concealed behind the
headliner and in the corner or C
pillar behind the doors.
•A headliner designed to flex open
above the side doors to allow Safety Canopy deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two crash sensors located on the C-pillar (one on each side)
(SuperCab and SuperCrew only).
•Crash sensors located on the front doors.
•Rollover sensor in the restraints control module (RCM).
The Safety Canopy system, in combination with safety belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second row seats. The Safety Canopy will not interfere with children
restrained using a properly installed child or booster seat because it is
designed to inflate downward from the headliner above the doors along
the side window opening.
Seating and Safety Restraints
206
2012 F-150(f12)
Owners Guide, 1st Printing
USA(fus)

The Safety Canopy system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the RCM to initiate Safety
Canopy inflation or when a certain likelihood of a rollover event is
detected by the rollover sensor.
The Safety Canopy is mounted to roof side-rail sheet metal, behind the
headliner, above each row of seats. The Safety Canopy is designed to
inflate between the side window area and occupants to further enhance
protection provided in side impact collisions and rollover events.
The fact that the Safety Canopy 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. The Safety
Canopy is designed to inflate in certain side impact collisions or rollover
events, not in rear impact, frontal or near-frontal collisions, unless the
collision causes sufficient lateral deceleration or rollover likelihood.
WARNING:Several Safety
Canopy system components
get hot after inflation. Do not
touch them after inflation.
WARNING:If the Safety Canopy system has deployed, the
Safety Canopy will not function again unless replaced. The
Safety Canopy system (including the A, B, C, and D pillar trim and
headliner) must be inspected and serviced by an authorized dealer. If
the Safety Canopy is not replaced, it will not function again, which will
increase the risk of injury in a future collision.

WARNING:When mounting replacement tires and wheels, you
should not exceed the maximum pressure indicated on the
sidewall of the tire to set the beads without additional precautions
listed below. If the beads do not seat at the maximum pressure
indicated, re-lubricate and try again.
When inflating the tire for mounting pressures up to 20 psi (1.38 bar)
greater than the maximum pressure on the tire sidewall, the following
precautions must be taken to protect the person mounting the tire:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and wheel bead seat area again.
3. Stand at a minimum of 12 ft (3.66 m) away from the tire wheel
assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20 psi (1.38 bar) greater than the
maximum pressure, a Ford dealer or other tire service professional
should do the mounting.
Always inflate steel carcass tires with a remote air fill with the person
inflating standing at a minimum of 12 ft (3.66 m) away from the tire
wheel assembly.
Important:Remember to replace the wheel valve stems when the road
tires are replaced on your vehicle.
It is recommended that the two front tires or two rear tires generally be
replaced as a pair.
The tire pressure sensors mounted in the wheels (originally installed on
your vehicle) are not designed to be used in aftermarket wheels.
The use of wheels or tires not recommended by Ford Motor Company
may affect the operation of your tire pressure monitoring system.
If the TPMS indicator is flashing, your TPMS is malfunctioning. Your
replacement tire might be incompatible with your TPMS, or some
component of the TPMS may be damaged.

Tire rotation
Rotating your tires at the recommended interval (as indicated in the
Scheduled Maintenancechapter) will help your tires wear more evenly,
providing better tire performance and longer tire life.
•Rear-wheel drive (RWD)
vehicles/Four-wheel drive (4WD)
vehicles (front tires at top of
diagram)
Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note:After having your tires rotated, check tire pressure and adjust to
the recommended inflation pressure.
WARNING:If the tire label shows different tire pressures for
the front and rear tires and the vehicle is equipped with TPMS
(tire pressure monitoring system), then the settings for the TPMS
sensors need to be updated. Always perform the TPMS reset procedure
after tire rotation. If the system is not reset, it may not provide a low
tire pressure warning when necessary. See the TPMS reset procedure
in this chapter.

following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
WARNING:The tire pressure monitoring system is NOT a
substitute for manually checking tire pressure. The tire pressure
should be checked periodically (at least monthly) using a tire gauge,
seeInflating your tiresin this chapter. Failure to properly maintain
your tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
Changing tires with a TPMS
Note:Each road tire is equipped
with a tire pressure sensor located
inside the tire/wheel cavity. The
pressure sensor is attached to the
valve stem. The pressure sensor is
covered by the tire and is not visible
unless the tire is removed. Care
must be taken when changing the
tire to avoid damaging the sensor.
It is recommended that you always
have your tires serviced by an
authorized dealer.
The tire pressure should be checked periodically (at least monthly) using
an accurate tire gauge, refer toInflating your tiresin this chapter.
Understanding your tire pressure monitoring system (TPMS)
The tire pressure monitoring system measures pressure in your four road
tires and sends the tire pressure readings to your vehicle. The low tire
pressure warning light will turn on if the tire pressure is significantly low.
Once the light is illuminated, your tires are under-inflated and need to be
inflated to the manufacturer’s recommended tire pressure. Even if the
light turns on and a short time later turns off, your tire pressure still
needs to be checked. Visit www.checkmytires.org for additional
information.
When your temporary spare tire is installed
When one of your road tires needs to be replaced with the temporary
spare, the TPMS will continue to identify an issue to remind you that the
damaged road wheel/tire needs to be repaired and put back on your
vehicle.
