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 toSeat-mounted side airbag system
later 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 toSide curtain airbag systemlater
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.
•Driver’s side knee airbag module.
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
backup power, the airbag ignitors and safety belt pretensioners.
Knee airbag system (driver’s side only)
The knee airbag is located under the instrument panel. The system
works along with the driver’s front airbag to help reduce injury to the
legs. When the driver’s airbag activates in a collision, the knee airbag
deploys from under the instrument panel.
As with front and side airbags, it is important to be properly seated and
restrained to reduce the risk of death or serious injury.

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.
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
uses apassenger airbag offor
pass airbag offindicator which will
light and stay lit to remind you that
the front passenger frontal airbag is
off. The indicator lamp is located in
the center stack of the instrument panel above the climate controls.
Note: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.
When the front passenger seat is not occupied (empty seat) or in the
event that the front passenger frontal airbag is enabled (may inflate), the
indicator lamp will be unlit.
The front passenger sensing system is designed to disable (will not
inflate) the front passenger’s frontal airbag when a rear facing infant
seat, a forward-facing child restraint, or a booster seat is detected.

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 (including side air
curtain systems).
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.
•The same warning light,
electronic control and diagnostic
unit as used for the front airbags.
•Two crash sensors located under
the outboard side of the front seats, attached near the floor.
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 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 crash sensors located under the outboard side of the front seats,
attached near the floor.
•Two crash sensors located at the base of the “C” pillars above the
wheel house.
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 or an unbuckled child or small person in the passenger
seat. The air curtain was designed to inflate between the side window
area and occupant to further enhance the 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.

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.

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.

ADVANCETRACSTABILITY ENHANCEMENT SYSTEM
Your vehicle is equipped with the AdvanceTracsystem. The
AdvanceTracsystem provides the following stability enhancement
features for certain driving situations:
•Traction control system (TCS), which functions to help avoid
drive-wheel spin and loss of traction.
•Electronic stability control (ESC), which functions to help avoid skids
or lateral slides
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracsystem. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac
system. Install any aftermarket stereo loudspeaker as far as possible from
the front center console, the tunnel, and the front seats in order to
minimize the risk of interfering with the AdvanceTracsensors. Reducing
the effectiveness of the AdvanceTracsystem could lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracsystem is an indication that at least
some of the tires have exceeded their ability to grip the road; this
could reduce the operator’s ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle rollover, personal injury
and death. If your AdvanceTracsystem activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTracsystem, the stability control light will illuminate
steadily, and you may hear a chime. If equipped with a message center,
the vehicle will also indicate a failure with the brake system, have the
system serviced by an authorized dealer immediately.
The AdvanceTracsystem automatically enables each time the engine is
started. All features of the AdvanceTracsystem (TCS and ESC) are
active and monitor the vehicle from start-up. However, the system will
only intervene if the driving situation requires it.

The RSS detects obstacles up to six
feet (two meters) from the rear
bumper with a decreased coverage
area at the outer corners of the
bumper, (refer to the figures for
approximate zone coverage areas).
As you move closer to the obstacle,
the rate of the tone increases. When
the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 10 inches (25.0 cm) from the
side of the vehicle, the tone will
sound for only three seconds. Once
the system detects an object
approaching, the tone will sound
again.
While receiving a warning the radio volume will be reduced to a
predetermined level. After the warning goes away, the radio will return
to the previous value.
The RSS automatically turns on when the gearshift lever is placed in R
(Reverse) and the ignition is on. A control in the message center allows
the driver to disable the system. Refer toMessage centerin the
Instrument Clusterchapter for more information.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
