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.
The SRS consists of the following items:
•Driver and passenger airbag modules (which include the inflators and
airbags)
•safety belt pretensioners
•Front passenger sensing system
•“Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing systemlater in this chapter.
•Driver and passenger side airbags
•One or more impact and safing sensors
•A readiness light and tone
•A diagnostic module
•The electrical wiring which connects the components
The diagnostic module monitors its own internal circuits as well as the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
back up power and the airbag ignitors.

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.
WARNING:If the safety belt pretensioners deploy in an
accident, they will not function again ( belt will not extract or
retract) and must be replaced immediately. Failure to replace the
retractor assemblies will increase the risk of 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,

WARNING:All occupants of the vehicle should always wear
their safety belts even when an airbag SRS is provided.
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 nylon 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.
•Two crash sensors located near the 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
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates airbag inflation.

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

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.
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.
