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.

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.
•the same indicator light, RCM (restraints control module) and
diagnostic unit used for the Personal safety system.
•Front passenger sensing system
•Passenger airbag off indicator light.
The airbag supplemental restraints are an integral part of the Personal
Safety System. They are designed to be deployed in cases where the
Personal Safety System has determined the occupant conditions and
crash severity are appropriate to activate these devices. Refer to the
Personal Safety System™section in this chapter.

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.
Children and airbags
For additional important safety
information, read all information on
safety restraints in this guide.
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear seat
than in the front seat. 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.

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 cover as possible while
maintaining vehicle control.
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.

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.
The fact that the airbags did not inflate 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. Side airbags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.

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.
The Safety Canopy system is designed to active 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.

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.
Safety practices
Driving habits have a great deal to do with your tire mileage and safety.
•Observe posted speed limits
•Avoid fast starts, stops and turns
•Avoid potholes and objects on the road
•Do not run over curbs or hit the tire against a curb when parking
WARNING:If your vehicle is stuck in snow, mud, sand, etc.,do
notrapidly spin the tires; spinning the tires can tear the tire and
cause an explosion. A tire can explode in as little as three to five
seconds.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Highway hazards
No matter how carefully you drive there’s always the possibility that you
may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove wheel and replace it with your spare tire and wheel. If

Note:After having your tires rotated, check tire pressure and adjust to
the recommended inflation pressure.
Note:The TPMS reset tool is ONLY provided for vehicles with different
front and rear tire pressures. The TPMS reset procedure needs to be
performed after tire rotation only on these vehicles.
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.
INFORMATION CONTAINED ON THE TIRE SIDEWALL
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
Information on “P” type tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
1.P:Indicates a tire, designated by
the Tire and Rim Association
(T&RA), that may be used for

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
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.

To restore the full functionality of the tire pressure monitoring system,
have the damaged road wheel/tire repaired and remounted on your
vehicle. For additional information, refer toChanging tires with a
TPMSin this section.
When you believe your system is not operating properly
The main function of the tire pressure monitoring system is to warn you
when your tires need air. It can also warn you in the event the system is
no longer capable of functioning as intended. Please refer to the
