•Driver seat position sensor.
• Front crash severity sensors.
• Restraints control module with impact and safing sensors.
• Restraint system warning light and backup tone.
• The electrical wiring for the airbags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position

How does the Restraint Safety System work?
The Restraint 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. During a crash, the
restraints control module 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.
SOS POST-CRASH ALERT SYSTEM™
The system flashes the direction indicator lamps and the horn sounds
(intermittently) in the event of a serious impact that deploys an airbag
equipped on your vehicle.
The horn and lamps turn off when:
• You press the hazard button.
• You press the panic button (if equipped) on the remote entry
transmitter.
• Your vehicle runs out of power.
DRIVER AND PASSENGER AIRBAGS
WARNING: Never place your arm or any objects over an airbag
module. Placing your arm over a deploying airbag can result in
serious arm fractures or other injuries. Objects placed on or over the
airbag inflation area may cause those objects to be propelled by the
airbag into your face and torso causing serious injury.

Note:Certain states require electric trailer brakes for trailers over a
specified weight. Be sure to check state regulations for this specified
weight. The maximum trailer weights listed may be limited to this
specified weight, as your vehicle’s electrical system may not include the
wiring connector needed to use electric trailer brakes.
Your vehicle may tow a trailer provided the maximum trailer weight is
less than or equal to the maximum trailer weight listed for your vehicle
configuration on the following chart.
To calculate the maximum loaded trailer weight for your vehicle:
1. Start with the gross combined weight rating for your vehicle model and axle ratio. See the following chart.
2. Subtract all of the following that apply to your vehicle: •Vehicle curb weight
• Hitch hardware weight, such as a draw bar, ball, locks or weight
distributing
• Driver weight
• Passenger(s) weight
• Payload, cargo and luggage weight
• Aftermarket equipment weight.
3. This equals the maximum loaded trailer weight for this combination.
Note: The trailer tongue load figures into the payload for your vehicle.
Reduce the total payload by the final trailer tongue weight.
Consult an authorized dealer to determine the maximum trailer weight
allowed for your vehicle if you are not sure.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•Do not tow a trailer until you drive your vehicle at least 1000 miles
(1600 kilometers).
• Consult your local motor vehicle laws for towing a trailer.
• See the instructions included with towing accessories for the proper
installation and adjustment specifications.
• Service your vehicle more frequently if you tow a trailer. See your
scheduled maintenance information.
• If you use a rental trailer, follow the instructions the rental agency
gives you.
For load specification terms found on the tire label and Safety
Compliance label and for instructions on calculating your vehicle’s load,
refer to Load limit in theLoad Carrying chapter.
Remember to account for the trailer tongue weight as part of your
vehicle load when calculating the total vehicle weight.
Trailer Towing Connector (Vehicles with a Trailer Towing Package
and 7–Pin Connector) When attaching the trailer wiring
connector to your vehicle, only use
a proper fitting connector that
works with the vehicle and trailer
functions. If your vehicle has a
trailer towing package, it may have
a 7–pin connector. Some connectors
may have the SAE J2863 logo,
which confirms that it is the proper
wiring connector and works correctly with your vehicle.

Trailer Lamps
WARNING:Never connect any trailer lamp wiring to the
vehicle’s tail lamp wiring; this may damage the electrical system
resulting in a fire. Contact an authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing up to get the feel of your
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels clear curbs and other obstacles.
When Towing a Trailer
• Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).
• When stopped in congested or heavy traffic during hot weather, place
the gearshift in position Pto aid engine and transmission cooling and
to help air conditioning performance.
• Turn off the speed control with heavy loads or in hilly terrain. The
speed control may turn off automatically when you are towing on
long, steep grades.
• Shift to a lower gear when driving down a long or steep hill. Do not
apply the brakes continuously, as they may overheat and become less
effective.
• If your transmission is equipped with a Grade Assist or Tow/Haul
feature, use this feature when towing. This provides engine braking
and helps eliminate excessive transmission shifting for optimum fuel
economy and transmission cooling.
• If your vehicle is equipped with AdvanceTrac™ with RSC, this system
may turn on during typical cornering maneuvers with a heavily loaded
trailer. This is normal. Turning the corner at a slower speed while
towing may reduce this tendency.

•If your vehicle is equipped with Continuous Controlled Damping
Suspension (CCD Suspension), you can select NORMAL or SPORT
drive control modes for better experience while towing a trailer. See
the Information Displays chapter for details on selecting driving
modes.
• If you are towing a trailer frequently in hot weather, hilly conditions,
at the gross combined weight rating (or any combination of these
factors), consider refilling your rear axle with synthetic gear lubricant
(if the axle is not already filled with it). See the Capacities and
Specifications chapter for the lubricant specification.
• Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
• Avoid parking on a grade. However, if you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in position P.
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not included with vehicle.)
Your vehicle may be equipped with a temporary or conventional spare
tire. A “temporary” spare tire is different in size (diameter or width),
tread-type (All-Season or All-Terrain) or is from a different manufacturer
than the road tires on your vehicle. Consult information on the tire label
or Safety Compliance label for limitations when using.
Launching or Retrieving a Boat or Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer beforebacking the trailer into
the water.
Note: Reconnect the wiring to the trailer afterremoving the trailer 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 centimeters)
above the bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
• Causing internal damage to the components.
• Affecting driveability, emissions, and reliability.
Replace the rear axle lubricant anytime the rear axle submerges in
water. Water may have contaminated the rear axle lubricant, which does
not normally require checking or changing unless it is leaking or other
axle repair is required.

Note:The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when using
snow tires and chains.
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:
• If possible, avoid fully loading your vehicle.
• Use only cable type chains or chains offered by Ford/Lincoln 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 as this may interfere with
suspension components.
• Only certain snow cables or chains have been approved by
Ford/Lincoln as safe for use on your vehicle with the following tires:
275/65R18.
• You should install snow cables or chains that have been rated as SAE
Class S.
• Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
• Do not exceed 30 mph (50 km/h) or less if recommended by the chain
manufacturer while using snow chains.
• Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and retighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
• Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
• Purchase chains or cables from a manufacturer that clearly labels body
to tire dimension restrictions. The snow chains or cables must be
mounted in pairs on the rear tires only.
If you have any questions regarding snow chains or cables, please
contact your Ford/Lincoln dealer.
