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
systemlater 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
back up 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.

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 nylon bag (airbag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
•The same warning light,
electronic control and diagnostic
unit as used for the front airbags.
•Two crash sensors mounted on the B pillar (one on each side of the
vehicle).
•Two crash sensors located at the C pillar behind the rear doors (one
on each side of the vehicle).
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. If the front passenger sensing system
detects an empty seat, the front passenger seat-mounted side airbag will
be deactivated. 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.
WARNING:Several air bag system components get hot after
inflation. Do not touch them after inflation.

How does the Safety Canopysystem work?
The design and development of the
Safety Canopysystem 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 Canopysystem 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 vehicle).
•A headliner designed to flex open
above the side doors to allow
Safety Canopydeployment.
•The same readiness airbag light, electronic control and diagnostic unit
as used for the front airbags.
•Two crash sensors mounted on the B pillar (one on each side of the
vehicle).
•Two crash sensors located at the C pillar behind the rear doors (one
on each side of the vehicle).
•Rollover sensor in the restraints control module (RCM).
The Safety Canopysystem, 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 or third row seats. The Safety Canopywill 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 Canopysystem 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 Canopyinflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.
The Safety Canopyis mounted to roof side-rail sheet metal, behind the
headliner, along the entire side of the vehicle. In certain lateral collisions
or rollover events, the Safety Canopysystem will be activated,
regardless of which seats are occupied. The Safety Canopyis 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 Canopydid 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
Canopyis 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.
WARNING:If the Safety
Canopysystem has
deployed, the Safety Canopywill
not function again unless replaced.
The Safety Canopysystem
(including the A, B, C, and D
pillar trim and headliner) must be
inspected and serviced by an
authorized dealer. If the Safety
Canopyis not replaced, it will
not function again, which will
increase the risk of injury in a
future collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAirbag readiness
section in theInstrument Clusterchapter. Routine maintenance of the
airbag is not required.
Any difficulty with the system is indicated by one or more of the
following:
•The readiness airbag light (same light as for front airbag system) will
either flash or stay lit.

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.
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

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 TPMS
Each road tire is equipped with
a tire pressure sensor fastened
to the inside rim of the wheel.
The pressure sensor is covered
by the tire and is not visible
unless the tire is removed. The
pressure sensor is located
opposite (180 degrees) from the
valve stem. 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 to
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. The Low
Tire Pressure Warning Lamp 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.
