SECURILOCKPASSIVE ANTI-THEFT SYSTEM (IF EQUIPPED)
SecuriLockpassive anti-theft system is an engine immobilization
system. This system is designed to help prevent the engine from being
started unless acoded key programmed to your vehicleis used. The
use of the wrong type of coded key may lead to a “no-start” condition.
The message center will display:STARTING SYSTEM FAULT.
Your vehicle comes with two coded keys; additional coded keys may be
purchased from your authorized dealer. The authorized dealer can
program your spare keys to your vehicle or you can program the keys
yourself. Refer toProgramming spare keysfor instructions on how to
program the coded key.
Note:The SecuriLockpassive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.
Note:Large metallic objects, electronic devices that are used to
purchase gasoline or similar items, or a second coded key on the same
key chain may cause vehicle starting issues. You need to prevent these
objects from touching the coded key while starting the engine. These
objects will not cause damage to the coded key, but may cause a
momentary issue if they are too close to the key when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded key and restart the engine.
Note: Do not leave a duplicate coded key in the vehicle. Always
take your keys and lock all doors when leaving the vehicle.

Automatic arming
The vehicle is armed immediately after turning the ignition off.
Automatic disarming
Switching the ignition on with acoded keydisarms the vehicle.
Replacement keys
If your keys are lost or stolen and you don’t have an extra coded key,
you will need to have your vehicle towed to an authorized dealer. The
key codes need to be erased from your vehicle and new coded keys will
need to be programmed.
Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLockkeys can be used. To program acoded keyyourself, you
will need two previously programmedcoded keys(keys that already
operate your vehicle’s engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are not available, you must
bring your vehicle to your authorized dealer to have the spare coded
key(s) programmed.
Please read and understand the entire procedure before you begin.
1. Insert the first previously
programmedcoded keyinto the
ignition and turn the ignition from
the 1 (off) position to the 3 (on)
position (maintain ignition in the 3
(on) position for at least one
second, but no more than
10 seconds).
2. Turn ignition from the 3 (on)
position back to the 1 (off) position
in order to remove the firstcoded
keyfrom the ignition.

3. After three seconds but within 10 seconds of removing the firstcoded
key,insert the second previously programmedcoded keyinto the
ignition and turn the ignition from the 1 (off) position to the 3 (on)
position (maintain ignition in the 3 (on) position for at least one second
but no more than 10 seconds).
4. Turn the ignition from the 3 (on) position back to the 1 (off) position
in order to remove the secondcoded keyfrom the ignition.
5. After three seconds but within 10 seconds of removing the second
coded key,insert the new unprogrammed key (new key/valet key) into
the ignition and turn the ignition from the 1 (off) position to the 3 (on)
position (maintain ignition in the 3 (on) position for at least one second,
but no more than 10 seconds). This step will program your new key to a
coded key.
6. To program additional new unprogrammed key(s), repeat Steps 1
through 5.
If successful, the new coded key(s) will start the vehicle’s engine.
If not successful, the new coded key(s) will not start the vehicle’s engine
and you may repeat Steps 1 through 5. If failure repeats, bring your vehicle
to your authorized dealer to have the new spare key(s) programmed.
PERIMETER ALARM SYSTEM (IF EQUIPPED)
The perimeter anti-theft system will warn you in the event of an
unauthorized entry to your vehicle.
If there is any potential perimeter anti-theft problem with your vehicle,
ensureALL remote entry transmittersare taken to the authorized
dealer to aid in troubleshooting.
Arming the system
When armed, this system will respond if unauthorized entry is
attempted. When unauthorized entry occurs, the system will flash the
park/turn lamps and will sound the horn.
The system is ready to arm whenever the key is removed from the
ignition. Either of the following actions will prearm the alarm system:
•Press the
control on the remote entry transmitter.
•Open a door and press the power door lock control to lock all the
doors, and then close the door.
•Press and hold the 7•8 and 9•0 controls on the keyless entry pad
at the same time to lock the doors (driver’s door must be closed).

Heated and cooled seats (if equipped)
The controls for the climate controlled seats are located on the climate
control system.
Heated Seats
WARNING:Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes, spinal cord
injury, medication, alcohol use, exhaustion, or other physical
conditions, must exercise care when using the seat heater. The seat
heater may cause burns even at low temperatures, especially if used
for long periods of time. Do not place anything on the seat that
insulates against heat, such as a blanket or cushion, because this may
cause the seat heater to overheat. Do not puncture the seat with pins,
needles, or other pointed objects because this may damage the heating
element which may cause the seat heater to overheat. An overheated
seat may cause serious personal injury.
•Do not place heavy objects on the seat.
•Do not operate the seat heater if water or any other liquid is spilled
on the seat. Allow the seat to dry thoroughly.
The heated seats will only function when the engine is running.
To operate the heated seats:
Press the heated seat button/symbol
to cycle through the various heat
settings and off. Warmer settings are
indicated by more indicator lights.
Cooled Seats

TRAILER TOWING
Note:The trailer towing chart in this section applies to vehicles
equipped with a gasoline engine; for vehicles equipped with a diesel
engine, refer to your diesel supplement.
Your vehicle may tow a Conventional/Class IV trailer or fifth-wheel trailer
provided the maximum trailer weight is less than or equal to the
maximum trailer weight for your engine and rear axle ratio.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully prior to and after any towing operation. Refer to
Transmission fluid temperature gaugein theInstrument Cluster
chapter for the transmission fluid temperature information.
To find the maximum trailer weight allowed for your vehicle, consult
your authorized dealer (or theRV and Trailer Towing Guideprovided
by your authorized dealer).
To calculate your maximum trailer weight on your own:
1.Pick-up trucks:Take curb weight, hitch hardware and the driver’s
weight, then subtract them from the GCWR listed for your vehicle
series and drive axle ratio listed on the following table.
2.
Chassis cabs and pick-up trucks with aftermarket equipment:
Weigh your vehicle at a certified scale and subtract this actual curb
weight, hitch hardware and the driver’s weight from the GCWR listed
for your vehicle series and drive axle ratio listed on the following table.
The weight of all additional cargo and passengers must be subtracted
from the maximum trailer weight calculated above.
Further trailer/hitch restrictions and limitations exist depending on the
type of trailer and hitch used. This information follows the table listing
the maximum GCWRs.
For load specification terms found on the label and instructions on
calculating your vehicle’s load, refer toVehicle loading - with and without
a trailerin this chapter when figuring the total weight of your vehicle.
Note:Do not exceed the tire ratings specified on the Tire Label or
Safety Compliance Certification Label.
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
