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 airbag-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:
• Driver and passenger dual-stage airbag supplemental restraints.
• Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
• Driver’s seat position sensor.
• Front crash severity sensor.
• Restraints Control Module (RCM).
• Restraint system warning light and back-up tone.
• The electrical wiring for the airbags, 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 may activate the safety belt pretensioners and/or either one or both
stages of the dual-stage airbag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or airbags 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 airbags 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.

• one or more impact and safing sensors and diagnostic monitor (RCM),
• a readiness light and tone
• the electrical wiring which connects the components.
The RCM (restraints control module) monitors its own internal circuits
and 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).
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 Airbag readiness section
in the Instrument Cluster chapter. 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 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, contact your
authorized dealer as soon as possible. Unless serviced, the system may
not function properly in the event of a collision.
Seat-mounted side airbag system
WARNING: Do not place objects or mount equipment on or
near the airbag cover on the side of the seatbacks of the front
seats or in front seat areas that may come into contact with a
deploying airbag. Failure to follow these instructions may increase the
risk of personal injury in the event of a collision.
WARNING: Do not use accessory seat covers. The use of
accessory seat covers may prevent the deployment of the side
airbags and increase the risk of injury in an accident.
WARNING: Do not lean your head on the door. The side airbag
could injure you as it deploys from the side of the seatback.

SNOW TIRES AND CHAINS
WARNING: Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and
performance of your vehicle, which could result in an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
Additionally, the use of non-recommended tires and wheels could
cause steering, suspension, axle or transfer case/power transfer unit
failure.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
• Use only cable type chains or chains offered by Ford as an accessory
or equivalent. Other conventional link type chains may contact and
cause damage to the vehicle’s wheel house and/or body.
• Do not install chains on the front wheels. Chains on the front wheels
may interfere with suspension components.
• Chains are not recommended for use on the P275/55R20 tire.
• Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
• Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
• If possible, avoid fully loading your vehicle.
• Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
• The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
• Do not exceed 30 mph (48 km/h) with tire chains on your vehicle.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or

Follow these guidelines to ensure safe towing procedure:
• Stay within your vehicle’s load limits. If exceeded, cargo should be
removed from the trailer and/or the vehicle until all weights are within
specified limits.
• Thoroughly prepare your vehicle for towing. Refer to Preparing to
tow in this chapter.
• Use extra caution when driving while trailer towing. Refer to Driving
while you tow in this chapter.
• Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the scheduled maintenance guide.
• Do not tow a trailer until your vehicle has been driven at least
500 miles (800 km). Additionally, during the first 500 miles (800 km)
that you tow a trailer, do not drive over 70 mph (113 km/h) and do
not make starts at full throttle.
• Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
Trailer towing (standard equipment):
Your vehicle is equipped with a integrated trailer hitch and a Class I
(4-pin) trailer electrical connector. The 4-pin connector supplies power
to tail lamps, stop lamps, and turn lamps. See the trailer towing chart for
the trailer towing weight recommendation.
Trailer towing (optionally equipped trailer tow package):
The optional trailer tow package includes heavy duty trailer tow wiring.
Both a Class I (4-pin) and IV (7-pin) trailer electrical connector are
provided. Under the instrument panel a electrical connector is provided
for a customer supplied aftermarket electronic brake controller. For
installing a customer supplied electronic brake controller, a electrical
jumper harness and trailer tow electrical instructions are included with
the optional trailer tow package.
The kit containing a electrical jumper and trailer tow electrical
instructions may be purchased from any authorized dealer (Part number
4L1Z-14A348-AA)
Note: Before towing a trailer, make sure the trailer brakes (if equipped)
and lamps are properly connected and functional. Electronic trailer
brakes (if equipped) refer to the instructions provided by the
aftermarket electronic brake controller manufacture for determining
trailer brake functionality.

Trailer towing tips
• Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
• Allow more distance for stopping with a trailer attached.
• If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
• The trailer tongue weight should be 10–15% of the loaded trailer
weight.
• If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to the Maintenance and Specifications chapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full throttle starts.
• After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
• To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
• Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
• do not allow the static water level to rise above the bottom edge of
the rear bumper.
• do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
