MIRRORS
Automatic dimming inside rear view mirror (if equipped)
Your vehicle is equipped with an
inside rear view mirror which has an
auto-dimming function. The
electronic day/night mirror will
change from the normal state to the
non-glare state when bright lights
(glare) reach the mirror. When the mirror detects bright light from front
or behind, it will automatically adjust (darken) to minimize glare.
Do not block the sensor on the backside of the mirror since this may
impair proper mirror performance.
Press the control to turn the mirror OFF or AUTO.
The mirror will automatically return to the normal state whenever the
vehicle is placed in R (Reverse)(when the mirror is on) to ensure a
bright clear view when backing up.
Electronic compass (if equipped)
The compass reading will remain accurate during most driving
conditions. Unknown to the driver, the compass is continuously
recalibrating due to magnetic fields and subtle, slow changes in vehicle
magnetics which can occur over the life of the vehicle.
The compass reading will remain fixed when significant changes in the
local magnetic field are experienced (such as steel bridges). The
compass will return to normal operation upon leaving the magnetized
area.
If highly magnetized items (such as magnetic mount antennas) are
placed very near the compass the display will change to ªCº for 15
seconds, then display all segments until the magnetized item is removed.
If a ªCº is displayed, refer toCompass calibration adjustment.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four
degrees between adjacent zones and will become noticeable as the
vehicle crosses multiple zones. A correct zone setting will eliminate this
error. Refer toCompass zone adjustment.

SAFETY RESTRAINTS
Personal Safety System
The Personal Safety System provides an improved overall level of frontal
crash protection to front seat occupants and is designed to help further
reduce the risk of air bag-related injuries. The system is able to analyze
different occupant conditions and crash severity before activating the
appropriate safety devices to help better protect a range of occupants in
a variety of frontal crash situations.
Your vehicle's Personal Safety System consists of:
²Driver and passenger dual-stage air bag supplemental restraints.
²Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
²Driver's seat position sensor.
²Front crash severity sensor.
²Restraints Control Module (RCM) with impact and safing sensors.
²Restraint system warning light and back-up tone.
²The electrical wiring for the air bags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, and indicator lights.

How does the personal safety system work?
The Personal Safety System can adapt the deployment strategy of your
vehicle's safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the Restraints Control Module (RCM). During a crash, the
RCM activates the safety belt pretensioners and/or either one or both
stages of the dual-stage air bag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or air bags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the Personal Safety System determined the
accident conditions (crash severity, belt usage, etc.) were not
appropriate to activate these safety devices. Front air bags and
pretensioners are designed to activate only in frontal and near-frontal
collisions, not rollovers, side-impacts, or rear-impacts unless the collision
causes sufficient longitudinal deceleration.
Driver and passenger dual-stage air bag supplemental restraints
The dual-stage air bags offer the capability to tailor the level of air bag
inflation energy. A lower, less forceful energy level is provided for more
common, moderate-severity impacts. A higher energy level is used for
the most severe impacts. Refer toAir bag Supplemental Restraints
section in this chapter.
Front crash severity sensor
The front crash severity sensor enhances the ability to detect the
severity of an impact. Positioned up front, it provides valuable
information early in the crash event on the severity of the impact. This
allows your Personal Safety System to distinguish between different
levels of crash severity and modify the deployment strategy of the
dual-stage air bags and safety belt pretensioners.
Driver's seat position sensor
The driver's seat position sensor allows your Personal Safety System to
tailor the deployment level of the driver dual-stage air bag based on seat
position. The system is designed to help protect smaller drivers sitting
close to the driver air bag by providing a lower air bag output level.
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
Seating and Safety Restraints
106

allows your Personal Safety System to tailor the air bag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety Beltsection in this chapter.
Front safety belt pretensioners
The safety belt pretensioners are designed to tighten the safety belts
firmly against the occupant's body during a collision. This maximizes the
effectiveness of the safety belts and helps properly position the occupant
relative to the air bag to improve protection. The safety belt
pretensioners can be either activated alone or, if the collision is of
sufficient severity, together with the air bags.
Front safety belt energy management retractors
The front 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 Beltsection 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 Lightsection in theInstrument Clusterchapter.
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.
²The warning light will either flash or stay lit.
²The warning light will not illuminate immediately after ignition is
turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System serviced at your dealership or by a qualified technician
immediately. Unless serviced, the system may not function properly in
the event of a collision.

Failure to replace the Belt and Retractor assembly could
increase the risk of injury in collisions.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
front outboard passenger seating positions.
The safety belt pretensioners are designed to activate only when the
safety belts are fastened during certain frontal or near-frontal collisions
with sufficient longitudinal deceleration. A safety belt pretensioner is a
device which tightens the webbing of the lap and shoulder belts in such
a way that they fit more snugly against the body.
The driver and front outboard passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the vehicle
is involved in a collision that results in the activation of the safety belt
pretensioners. Refer to theSafety belt maintenancesection in this
chapter.
In the event of a collision resulting in the deployment of the
front air bags, the front safety belts must be replaced if they
were in use. Failure to replace the safety belt assembly could result in
severe personal injuries in the event of a collision.
Safety belt usage sensors
The driver and front outboard passenger safety belt buckles are
equipped with sensors that detect if the safety belts are fastened. The
sensors provide information to the Personal Safety System which can
then adapt the air bag deployment or safety belt pretensioner activation
based upon safety belt usage.
The Personal Safety System provides the most benefit to belted
occupants. The system monitors and tailors the air bag
deployment based upon safety belt usage. Failure to properly wear
your safety belt will increase your risk of injury.

AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM
Your vehicle is equipped with a crash sensing and diagnostic module
which records information about the air bag and sensor systems. In the
event of a collision this module may save information related to the
collision including information about the air bag system and impact
severity. This information will assist Ford in the servicing of your vehicle
and may help Ford better understand real world collisions and further
improve the safety of future vehicles.
The air bag supplemental restraint system is designed to work in
conjunction with the safety belts to help protect the driver and front
outboard passenger from certain upper body injuries. The term
ªsupplemental restraintº means the air bags are intended as a
supplement to the safety belts. Air bags alone cannot protect as well as
air bags plus safety belts in impacts for which the air bags are designed
to deploy, and air bags do not offer any protection in crashes for which
they do not deploy.
HOW DO THE AIR BAG SUPPLEMENTAL RESTRAINTS WORK?
The air bag supplemental restraint system consists of:
²driver and passenger dual stage air bag modules (which include the
inflators and air bags).
²side air bags (if equipped). Refer toSide air bag systemlater in this
chapter.
²one or more impact and safing sensors.
²the same indicator light, RCM (restraints control module) and
diagnostic unit used for the Personal safety system.

Steps you can take to properly position yourself away from the airbag:
²Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
²Recline the seat slightly (one or two degrees) from the upright
position.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln Mercury dealer.
The front passenger air bag is not designed to offer protection to
occupants in the center front seating position.
Modifications to the front end of the vehicle, including frame,
bumper, front end body structure and tow hooks may affect the
performance of the air bag sensors increasing the risk of injury. Do not
modify the front end of the vehicle.

How does the side air bag system work?
The side air bag system consists of
the following:
²An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
²A special seat cover designed to
allow airbag deployment.
²The same warning light,
electronic control and diagnostic
unit as used for the front air
bags.
²Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated, even if the respective seat is not
occupied. The air bag was designed to inflate between the door panel
and occupant to further enhance the protection provided occupants in
side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
The fact that the air bags 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 air bags 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.

Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
Park brake warning chime
Sounds when the parking brake is set, the engine is running and the
transaxle is not in P (Park) or N (Neutral). The chime will shut off when
the parking brake is disengaged.
TRACTION CONTROLY(IF EQUIPPED)
Your vehicle may be equipped with the optional Traction Controly
system. This system helps you maintain the stability and steerability of
your vehicle. It is especially useful on slippery and/or hilly road surfaces.
The system operates by detecting and controlling wheel spin. The system
borrows many of the electronic and mechanical elements already present
in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess front wheel spin to be detected by the
Traction Controlyportion of the ABS computer. Any excessive wheel
spin is controlled by automatically applying and releasing the front
brakes in conjunction with engine torque reductions. Engine torque
reduction is realized via the fully electronic spark and fuel injection
systems. This process is very sensitive to driving conditions and very fast
acting. The front wheels ªsearchº for optimum traction several times a
second and adjustments are made accordingly.
The Traction Controlysystem will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow, ice covered
and gravel roads.
