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 air bag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety restraintssection in this chapter.
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 side collisions and rollovers when the
vehicle is equipped with the Safety Canopy
system. This maximizes 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 air bags.
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 toSafety restraintssection 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 air bag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, and the driver
seat position sensor. 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 the 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.

Front and second row safety belt height adjustment
Your vehicle has safety belt height
adjustments for the driver, right
front passenger and second row
outboard passengers. Adjust the
height of the shoulder belt so the
belt rests across the middle of your
shoulder.
To lower the shoulder belt height,
push the button and slide the height
adjuster down. To raise the height
of the shoulder belt, push the
button and slide the height adjuster up. Pull down on the height adjuster
to make sure it is locked in place.
Position the safety belt height adjusters so that the belt rests
across the middle of your shoulder. Failure to adjust the safety
belt properly could reduce the effectiveness of the seat belt and
increase the risk of injury in a collision.

complete.
Safety belt extension assembly
If the safety belt is too short when fully extended, there is a 8 inch (20
cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained from your dealer at no cost.
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.
Do not use extensions to change the fit of the shoulder belt
across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front seat belt buckle
assemblies, buckle support assemblies (slide bar-if equipped), shoulder
belt height adjusters (if equipped), shoulder belt guide on seatback (if
equipped), child safety seat LATCH and tether anchors, and attaching
hardware, should be inspected after a collision. Ford Motor Company

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 nylon curtain with a
gas generator concealed behind
the headliner and above the doors
(one on each side of the vehicle).
•A headliner that will flex to 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 side crash sensors mounted at the base of the B-pillar (one on
each side of the vehicle).
•Two side crash sensors located at the c-pillar behind the rear doors
(one on each side of the vehicle).
•Roll over sensor in the restraints control module (RCM).
The Safety Canopy
system, in combination with seat 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 or third row seats (if equipped). 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 openings.
The Safety Canopy
system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to
close an electrical circuit that initiates Safety Canopy
inflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.

Any difficulty with the system is indicated by one or more of the
following:
•The readiness light (same light as for front air bag system) will either
flash or stay lit.
•The readiness 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 light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a collision
or rollover event.
Disposal of air bags and air bag equipped vehicles (including
pretensioners)
See your local dealership or qualified technician. Air bags MUST BE
disposed of by qualified personnel.
SAFETY RESTRAINTS FOR CHILDREN
See the following sections for directions on how to properly use safety
restraints for children. Also seeAir bag supplemental restraint system
(SRS)in this chapter for special instructions about using air bags.
Important child restraint precautions
You are required by law to use safety restraints for children in the U.S.
and Canada. If small children (generally children who are four years old
or younger and who weigh 40 lb. [18 kg] or less) ride in your vehicle, you
must put them in safety seats made especially for children. Many states
require that children use approved booster seats until they are eight
years old. Check your local and state or provincial laws for specific
requirements regarding the safety of children in your vehicle. When
possible, always place children under age 12 in the rear seat of your
vehicle. Accident statistics suggest that children are safer when properly
restrained in the rear seating positions than in the front seating position.
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.
Always follow the instructions and warnings that come with any infant or
child restraint you might use.

13.Maximum Permissible Inflation Pressure:Indicates the tire
manufacturers’maximum permissible pressure and/or the pressure at
which the maximum load can be carried by the tire. This pressure is
normally higher than the manufacturer’s recommended cold inflation
pressure which can be found on either the tire label or certification label
which is located on the B-Pillar or the edge of the driver’s door. The cold
inflation pressure should never be set lower than the recommended
pressure on the vehicle label.
The tire suppliers may have additional markings, notes or warnings such
as standard load, radial tubeless, etc.
Additional information contained on the tire sidewall for“LT”type
tires
“LT”type tires have some additional
information beyond those of“P”

TIRE PRESSURE MONITORING SYSTEM (TPMS)
When the Tire Pressure Monitoring
System warning light is lit, one or
more of your tires is significantly
under-inflated. You should stop and
check your tires as soon as possible,
and inflate them to the proper pressure as indicated on the vehicle’s tire
information placard (label). Driving on a significantly under-inflated tire
causes the tire to overheat and can eventually lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability. Even if your vehicle is
equipped with a Tire Pressure Monitoring System, it is still important
that you manually check the inflation pressure of your tires regularly.
Each tire, including the spare, should be checked monthly when cold and
set to the recommended inflation pressure which can be found on either
the tire label or certification label which is located on the B-Pillar or the
edge of the driver’s door.
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, see
Inspecting and inflating 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 TPMS
It is recommended that you always
have your tires serviced by a dealer
or qualified technician.Each road
tire is equipped with a tire
pressure sensor mounted on the
wheel inside the tire connected
to the valve stem. The tire
pressure sensor must be
unbolted from the wheel prior to
tire removal. The sensor can be
removed by loosening the nut at the valve stem. Failure to
remove the sensor may damage it.The rubber grommet (washer)
between the wheel and the tire pressure sensor needs to be replaced
whenever the sensor is removed to minimize air leaks.

The tire pressure should be checked periodically (at least monthly) using
an accurate tire gauge, refer toInspecting and inflating 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 every
minute while you are driving and once an hour when your vehicle is
parked. The Low Tire Warning Lamp will turn ON if the tire pressure is
25% below the pressure listed on the tire label (approximately 6 to 9 psi
below the manufacturer’s recommend tire pressure). If the tire pressure
increases 2 psi above the“Light ON”threshold, then the TPMS light will
turn OFF. 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.
In short, once the light has turned ON, at least one tire may be under
inflated.
When your temporary spare tire is installed
When one of your road tires needs to be replaced with the temporary
spare, the TPMS system 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. During this time, the low tire warning light can periodically
return or stay on, depending on the state of the damaged road
wheel/tire. This will include the message center messages (if equipped).
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 TPMS
in 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
following chart for information concerning your Tire Pressure Monitoring
System:
