Front safety belt energy management retractors
The front outboard 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
feature- front outboardsection 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 light and chimessection in theInstrument Cluster
chapter. 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 airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and front passenger sensing system. 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.
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after ignition is
turned on.
•A 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 an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Safety belt precautions
WARNING:Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING:To reduce the risk of injury, make sure children sit
where they can be properly restrained.

In case there is a problem with the
front passenger sensing system, the
airbag readiness light in the
instrument cluster will stay lit.
If the airbag readiness light 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 light is
no longer illuminated
•If the airbag readiness light 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 theCustomer
Assistancesection of thisOwner’s Guide.
WARNING:Any alteration/modification to the front passenger
seat may affect the performance of the front passenger sensing
system.
Determining if the system is operational
The supplemental restraint system uses a warning indicator light in the
instrument cluster or a back-up tone to indicate the condition of the
system. Refer to theWarning lights and chimessection in the
Instrument Clusterchapter. Routine maintenance of the airbag is not
required.

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 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.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAirbag readiness
section in theInstrument Clusterchapter. Routine maintenance of the
airbag is not required.

Move a child to a different seating location if the shoulder belt does not
stay positioned on the shoulder during use.
Follow all instructions provided by the manufacturer of the booster seat.
WARNING:Never place, or allow a child to place, the shoulder
belt under a child’s arm or behind the back because it reduces
the protection for the upper part of the body and may increase the risk
of injury or death in a collision.
Child restraint and safety belt maintenance
Inspect the vehicle safety belts and child safety seat systems periodically
to make sure they work properly and are not damaged. Inspect the
vehicle and child seat safety belts to make sure there are no nicks, tears
or cuts. Replace if necessary. All vehicle safety belt assemblies, including
retractors, buckles, front safety 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 LATCH and tether anchors, and attaching hardware, should be
inspected after a collision. Refer to the child restraint manufacturer’s
instructions for additional inspection and maintenance information
specific to the child restraint. Ford Motor Company recommends that all
safety belt assemblies in use in vehicles involved in a collision be
replaced. However, if the collision was minor and an authorized dealer
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.
For proper care of soiled safety belts, refer toInteriorin theCleaning
chapter.
WARNING:Failure to inspect and if necessary replace the
safety belt assembly or child restraint system under the above
conditions could result in severe personal injuries in the event of a
collision.

Improper or inadequate vehicle maintenance can cause tires to wear
abnormally. Inspect all your tires, including the spare, frequently, and
replace them if one or more of the following conditions exist:
Tire wear
When the tread is worn down to
1/16th of an inch (2 mm), tires must
be replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or “wear bars”, which
look like narrow strips of smooth
rubber across the tread will appear
on the tire when the tread is worn
down to 1/16th of an inch (2 mm).
When the tire tread wears down to
the same height as these “wear bars”, the tire is worn out and must be
replaced.
Damage
Periodically inspect the tire treads and sidewalls for damage (such as
bulges in the tread or sidewalls, cracks in the tread groove and
separation in the tread or sidewall). If damage is observed or suspected
have the tire inspected by a tire professional. Tires can be damaged
during off-road use, so inspection after off-road use is also
recommended.
WARNING: Age
Tires degrade over time depending on many factors such as
weather, storage conditions, and conditions of use (load, speed,
inflation pressure, etc.) the tires experience throughout their lives.
In general, tires should be replaced after six years regardless of tread
wear. However, heat caused by hot climates or frequent high loading
conditions can accelerate the aging process and may require tires to be
replaced more frequently.
You should replace your spare tire when you replace the road tires or
after six years due to aging even if it has not been used.

•Do not run over curbs or hit the tire against a curb when parking
WARNING:If your vehicle is stuck in snow, mud, sand, etc.,do
notrapidly 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.
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.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you’re driving, the wheels may be
out of alignment. Have an authorized dealer check the wheel alignment
periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by an authorized dealer.
Front wheel drive (FWD) vehicles and those with an independent rear
suspension (if equipped) may require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire rotation
Rotating your tires at the recommended interval (as indicated in the
scheduled maintenance informationthat comes with your vehicle) will
help your tires wear more evenly, providing better tire performance and
longer tire life.
