Children and airbagsChildren 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.
NEVER place 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 pretensioners and
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 to Seat-mounted side airbag system
later in this chapter
• safety belt pretensioners
• one or more impact and safing sensors

backup power, the airbag ignitors and safety belt pretensioners.
FRONT PASSENGER SENSING SYSTEM
WARNING: Even with Advanced Restraints Systems, children 12
and under should be properly restrained in a rear seating position.
WARNING: Sitting improperly out of position or with the seat
back reclined too far can take off weight from the seat cushion
and affect the decision of the front passenger sensing system, resulting
in serious injury or death in a crash.
Always sit upright against your seatback, with your feet on the floor.
WARNING: To reduce the risk of possible serious injury:
Do not stow objects in seat back map pocket (if equipped) or
hang objects off seat back if a child is in the front passenger seat.
Do not place objects underneath the front passenger seat or between
the seat and the center console (if equipped).
Check the “passenger airbag off” or “pass airbag off” indicator lamp for
proper airbag Status.
Failure to follow these instructions may interfere with the passenger
seat sensing system.
WARNING: Any alteration/modification to the front passenger
seat may affect the performance of the front passenger sensing
system.

This system works with sensors that are part of the front passenger’s
seat and safety belt to detect the presence of a properly seated occupant
and determine if the front passenger’s frontal airbag should be enabled
(may inflate) or not.The front passenger sensing system
uses a pass airbag off indicator
which will illuminate and stay lit to
remind you that the front passenger
frontal airbag is disabled.
The indicator lamp is located under
the climate controls. The indicator
lamp will illuminate for a short
period of time when the ignition is turned to the on position to confirm
it is functional.
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.
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.
• When the front passenger sensing system enables the front passenger
frontal airbag (may inflate), the passenger airbag status indicator will
illuminate the ON lamp and remain illuminated.
If a person of adult size is sitting in the front passenger’s seat, but the
pass airbag off indicator lamp is lit, it is possible that the person isn’t
sitting properly in the seat. If this happens:
• Turn the vehicle off and ask the person to place the seatback in the
full upright position.

To know if the front passenger sensing system is operating
properly, refer toCrash sensors and Airbag Indicator later in
this chapter.
If the airbag readiness lamp is lit, do the following:
The driver and/or adult passengers should check for any objects that
may be lodged underneath the front passenger seat or cargo interfering
with the seat.
If objects are lodged and/or cargo is interfering with the seat; please take
the following steps to remove the obstruction:
• Pull the vehicle over.
• Turn the vehicle off.
• Driver and/or adult passengers should check for any objects lodged
underneath the front passenger seat or cargo interfering with the seat.
• Remove the obstruction(s) (if found).
• Restart the vehicle.
• Wait at least two minutes and verify that the airbag readiness lamp is
no longer illuminated
• If the airbag readiness lamp remains illuminated, this may or may/not
be a problem due to the front passenger sensing system.
DO NOT attempt to repair or service the system; take your vehicle
immediately to an authorized dealer.
If it is necessary to modify an advanced front airbag system to
accommodate a person with disabilities, contact the Ford Customer
Relationship Center at the phone number shown in the Customer
Assistance section of this Owner’s Manual.
Determining if the system is operational
The system uses a warning indicator light in the instrument cluster or a
backup tone to indicate the condition of the system. Routine
maintenance of the airbag is not required.
A difficulty with the system is indicated by one or more of the following: •The readiness light (same light for front and side airbag
system) will either flash or stay lit.
• The readiness light will not illuminate immediately after ignition is
turned on.
• An information message will appear in the message center.

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 an
inflator 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 and on the rocker
behind the C pillar (one sensor
on each pillar 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. 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
acceleration 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:Do not attempt to service, repair, or modify the side air
curtain system, its fuses, the A, B, or C pillar trim, or the headliner
on a vehicle containing a side air curtain. See your authorized dealer.
WARNING: All occupants of the vehicle, including the driver,
should always wear their safety belts even when an inflatable
curtain is provided.
WARNING: To reduce the risk of injury, do not obstruct or place
objects in the deployment zone of the inflatable curtain.
How does the side air curtain system work? The design and development of the
side air curtain 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 side air
curtain systems).
The side air curtain system consists
of the following:
•An inflatable curtain with a gas
generator concealed behind the
headliner and above the doors.
• The headliner will flex to open above the side doors to allow air
curtain deployment.
• The same warning light, electronic control and diagnostic unit as used
for the front airbags.
• Two pressure sensors located in the front doors.
•
Two crash sensors located on the rocker panel behind the lower C pillar.
Side air curtains and side airbags, in combination with safety belts, can
help reduce the risk of severe injuries in the event of a significant side
impact collision.

Children 12 years old and under should always be properly restrained in
the rear seats. The side air curtain 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 side air curtains are mounted to the sheet metal above the first and
second row seats. In certain lateral collisions, the air curtain and
seat-mounted side airbag on the side affected by the collision will be inflated,
except that the passenger sensing system will deactivate the passenger
seat-mounted side airbag if it detects an empty unbuckled passenger seat.
The air curtain was designed to inflate between the side window area and
occupant to further enhance the head protection provided to occupants in
side impact collisions. The seat-mounted side airbag was designed to inflate
between the door panel and occupant to further enhance the protection
provided occupants in side impact collisions.
The side air curtain system SRS is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the sensors to close an
electrical circuit that initiates air curtain and seat-mounted side airbag
inflation.
The fact that the side air curtain and seat-mounted side airbag 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. The side air curtain system is 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.
WARNING: If the side air curtain has deployed, the air curtain
will not function again. The side air curtain system (including
the A, B and C pillar trim and headliner) must be inspected and
serviced by an authorized dealer. If the air curtain is not replaced, the
unrepaired area will increase the risk of injury in a collision.

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
WARNING: If your vehicle is stuck in snow, mud, sand, etc., do
not rapidly 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.
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
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
you cannot detect a cause, have the vehicle towed to the nearest repair
facility or tire dealer to have the vehicle inspected.

replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
The tire pressure monitoring system complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the
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.
Changing Tires with a TPMSNote:Each road tire is equipped
with a tire pressure sensor located
inside the tire and wheel assembly
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 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 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.
