Heated outside mirrorsR(if equipped)
Both mirrors are heated
automatically to remove ice, mist
and fog when the rear window
defrost is activated.
Do not remove ice from the
mirrors with a scraper or
attempt to readjust the mirror
glass if it is frozen in place.
These actions could cause
damage to the glass and mirrors.
Fold-away mirrors
Pull the side mirrors in carefully
when driving through a narrow
space, like an automatic car wash.
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.

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.
²Passenger occupant classification sensor (if equipped).
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, passenger occupant classification sensor (if equipped), 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.

Passenger occupant classification sensor (OCS) (if equipped)
If your vehicle is equipped with this feature, there will be a label located
under the front passenger seat which is marked ªOCSº. Alternatively, you
may take your vehicle to any Ford or Lincoln Mercury dealer for
assistance.
For air bags to do their job they must inflate with great force, and this
force can pose a potentially deadly risk to occupants that are very close
to the air bag when it begins to inflate. For some occupants, like infants
in rear-facing child seats, this occurs because they are initially sitting
very close to the air bag. For other occupants, this occurs when the
occupant is not properly restrained by seat belts or child safety seats and
they move forward during pre-crash braking. The most effective way to
reduce the risk of unnecessary injuries is to make sure all occupants are
properly restrained. Accident statistics suggest that children are much
safer when properly restrained in the rear seating positions than in the
front.
Air bags can kill or injure a child in a child seat.NEVERplace a
rear-facing child seat in front of an active air bag. If you must
use a forward-facing child seat in the front seat, move the seat all the
way back.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
The passenger occupant classification sensor can automatically turn off
the passenger front air bag and side air bag (if equipped). The system is
designed to help protect small (child size) occupants from air bag
deployments when they are improperly seated or restrained in the front
passenger seat contrary to proper child-seating or restraint usage
recommendations. Even with this technology, parents areSTRONGLY
encouraged to always properly restrain children in the rear seat. The
sensor also turns off the air bag(s) when the passenger seat is empty to
prevent unnecessary replacement of the air bag(s) after a collision.
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
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 toEnergy management featuresection 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 the
Warning 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, driver seat
position sensor, and passenger occupant classification sensor (if
equipped). 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.

Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front seat belt buckle
assemblies, buckle support assemblies (slide bar-if equipped), shoulder
belt height adjusters (if equipped), shoulder belt guide on seatback (if
equipped), child safety seat tether bracket assemblies (if equipped),
LATCH child seat tether anchors and lower anchors (if equipped), and
attaching hardware, should be inspected after a collision. Ford Motor
Company recommends that all safety belt assemblies used in vehicles
involved in a collision be replaced. However, if the collision was minor
and a qualified technician finds that the belts do not show damage and
continue to operate properly, they do not need to be replaced. Safety
belt assemblies not in use during a collision should also be inspected and
replaced if either damage or improper operation is noted.
Failure to inspect and if necessary replace the safety belt
assembly under the above conditions could result in severe
personal injuries in the event of a collision.
Refer toCleaning and maintaining the safety beltsin theCleaning
chapter.
AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
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 Motor Company in servicing
the vehicle and in helping to better understand real world collisions and
further improve the safety of future vehicles.

Do not attempt to service, repair, or modify the air bag
supplemental restraint systems or its fuses. See your Ford or
Lincoln Mercury dealer.
The front passenger air bag is not designed to offer protection to
an occupant 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.
Children and air bags
For additional important safety
information, read all information on
safety restraints in this guide.
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.
Air bags can kill or injure a
child in a child seat.
NEVERplace a rear-facing child
seat in front of an active air bag. If
you must use a forward-facing
child seat in the front seat, move
the seat all the way back.

How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
longitudinal 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. Air bags are designed to inflate in frontal and
near-frontal collisions, not rollover, side-impact, or rear-impacts unless
the collision causes sufficient longitudinal deceleration.
The air bags inflate and deflate
rapidly upon activation. After air bag
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
air bag. 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 air bag may also cause abrasions, swelling or temporary
hearing loss. Because air bags 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 air bag deployment. Thus, it is extremely important that occupants be
properly restrained as far away from the air bag module as possible while
maintaining vehicle control.
