CABIN AIR FILTER
The cabin air filter element is designed to reduce the concentration of
airborne particles such as dust, spores and pollen in the air being
supplied to the interior of the vehicle. The presence of a particulate filter
element provides the following benefits:
•Improves your driving comfort by reducing particle concentration.
•Improves the interior compartment cleanliness.
•Protects the climate control components from particle deposits.
Note:A cabin air filter must be installed at all times to prevent foreign
objects from entering the system. Running the system without a filter in
place could result in degradation or damage to the system.
For replacement intervals regarding the cabin air filter, see the
scheduled maintenance information. For more information regarding
your filter, see your authorized dealer.

Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions, and in side collisions and rollovers. This helps
increase the effectiveness of the safety belts. In frontal collisions, the
safety belt pretensioners can be activated alone or, if the collision is of
sufficient severity, together with the front airbags.
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 lights 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, rear outboard
inflatable belt (if equipped), 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.

•Wait at least two minutes and verify that the airbag readiness light in
the instrument cluster is no longer illuminated
•If the airbag readiness light in the instrument cluster 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 Guideor see your authorized dealer.
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 backup 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.
A difficulty with the system is indicated by one or more of the following:
•The readiness light (same light
for front and side airbag system)
will either flash or stay lit.
•The readiness 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/or light are repaired.
If any of these things happen, even intermittently, have the supplemental
restraint system serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.

The Safety Canopy is mounted to roof side-rail sheet metal, behind the
headliner, above each row of seats. In certain lateral collisions or rollover
events, the Safety Canopy system will be activated, regardless of which
seats are occupied. The Safety Canopy is designed to inflate between the
side window area and occupants to further enhance protection provided
in side impact collisions and rollover events.
The fact that the Safety Canopy 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. The Safety
Canopy is designed to inflate in certain side impact collisions or rollover
events, not in rear impact, frontal or near-frontal collisions, unless the
collision causes sufficient lateral deceleration or rollover.
WARNING:If the Safety
Canopy system has
deployed, the Safety Canopy will
not function again unless replaced.
The Safety Canopy system
(including the A, B, C, and D
pillar trim and headliner) must be
inspected and serviced by an
authorized dealer. If the Safety
Canopy is not replaced, it will not
function again, which will increase
the risk of injury in a future
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.
Any difficulty with the system is indicated by one or more of the following:
•The readiness airbag light (same light as for front airbag system) will
either flash or stay lit.
•The readiness light will not illuminate immediately after ignition is
turned on.

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), rear inflatable
safety belts (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.

VEHICLE CHARACTERISTICS
Four-wheel drive (4WD) system (if equipped)
A vehicle equipped with 4WD (when selected) has the ability to use all
four wheels to power itself. This increases traction which may enable you
to safely drive over terrain and road conditions that a conventional
two-wheel drive vehicle cannot.
Power is supplied to all four wheels through a transfer case or power
transfer unit. 4WD vehicles allow you to select different drive modes as
necessary. Information on transfer case operation and shifting procedures
can be found in theDrivingchapter. Information on transfer case
maintenance can be found in theMaintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
while the vehicle is moving can cause a momentary clunk and ratcheting
sound. These sounds are normal as the front drivetrain comes up to
speed and is not cause for concern.
WARNING:Do not become overconfident in the ability of 4WD
vehicles. Although a 4WD vehicle may accelerate better than
two-wheel drive vehicle in low traction situations, it won’t stop any
faster than two-wheel drive vehicles. Always drive at a safe speed.

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.

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 Guidechapter) will help your tires wear more
evenly, providing better tire performance and longer tire life.
•Front-wheel drive
(FWD)/All-wheel drive (AWD)
vehicles (front tires at top of
diagram)
Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note:After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.
INFORMATION CONTAINED ON THE TIRE SIDEWALL
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
