KEYS
Your vehicle is equipped with two
Integrated Keyhead Transmitters
(IKTs). The IKT functions as both a
programmed ignition key that
operates all the locks and starts the
vehicle, and a remote keyless entry
transmitter.
Your IKTs are programmed to your vehicle; using a non-programmed key
will not permit your vehicle to start. If you lose your authorized dealer
supplied IKTs, replacement IKTs are available through your authorized
dealer. Standard SecuriLock™ keys without remote entry transmitter
functionality can also be purchased from your authorized dealer if
desired.
Always carry a spare key with you in case of an emergency.
For more information regarding programming replacement IKTs, refer to
theSecuriLock™ passive anti-theft systemsection later in this chapter.
Note:Your vehicle’s IKTs were
issued with an adhesive security
label on them that provides
important vehicle key cut
information. It is recommended that
you maintain the label in a safe
place for future reference, such as
the inside front cover of this
Owner’s Guide.

To replace the battery:
1. Twist a thin coin in the slot of the
IKT near the key ring in order to
remove the battery cover.
2. Do not wipe off any grease on the
battery terminals on the back
surface of the circuit board.
3. Remove the old battery.Note:Please refer to local regulations when
disposing of transmitter batteries.
4. Insert the new battery. Refer to the instructions inside the IKT for the
correct orientation of the battery. Press the battery down to ensure that
the battery is fully seated in the battery housing cavity.
5. Snap the battery cover back onto the key.
Note:Replacement of the battery willnotcause the IKT to become
deprogrammed from your vehicle. The IKT should operate normally after
battery replacement.
Replacing lost Integrated Keyhead Transmitters (IKTs)
If you would like to have your Integrated Keyhead Transmitters
reprogrammed because you lost one, or would like to buy additional
IKTs, you can either reprogram them yourself, or takeall IKTsto your
authorized dealer for reprogramming.
How to reprogram your Integrated Keyhead Transmitters (IKTs)
To program a new Integrated Keyhead Transmitter yourself, refer to
Programming spare keysin theSecuriLock™ passive anti-theft
section of this chapter.Note:At least two IKTs are required to perform
this procedure yourself.

SECURILOCK™ PASSIVE ANTI-THEFT SYSTEM
SecuriLock™ passive anti-theft system is an engine immobilization
system. This system is designed to help prevent the engine from being
started unless acoded Integrated Keyhead Transmitter (IKT)
programmed to your vehicleis used. The use of the wrong type of
coded key may lead to a “no-start” condition.
Your vehicle comes with two coded Integrated Keyhead Transmitters;
additional coded IKTs may be purchased from your authorized dealer.
Standard SecuriLock™ keys without remote entry transmitter
functionality can also be purchased from your authorized dealer if
desired. The authorized dealer can program your spare IKTs to your
vehicle or you can program the IKTs yourself. Refer toProgramming
spare Integrated Keyhead Transmittersfor instructions on how to
program the coded key.
Note:The SecuriLock™ passive 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 IKT while starting the engine. These
objects will not cause damage to the coded IKT, but may cause a
momentary issue if they are too close to the IKT when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded IKT and restart the engine.

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
You can program your own Integrated Keyhead Transmitters or standard
SecuriLock™ coded keys to your vehicle. This procedure will program
both the engine immobilizer keycode and the remote entry transmitter
portion of the IKT to your vehicle.Note: A maximum of eight coded
keys can be programmed to your vehicle; only four of these eight can be
IKTs with remote entry functionality.
Tips:
•Only use Integrated Keyhead Transmitters (IKTs) or standard
SecuriLock™ keys.
•You must have two previously programmed coded keys (keys that
already operate your vehicle’s engine) and the new unprogrammed
key(s) readily accessible.
•If two previously programmed coded keys are not available, you must
take your vehicle to your authorized dealer to have the spare key(s)
programmed.
Please read and understand the
entire procedure before you begin.
1. Insert the first previously
programmedcoded keyinto the
ignition.
2. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position.
Keep the ignition in the 3 (RUN) position for at least three seconds, but
no more than 10 seconds.
3. Turn the ignition to the 1 (LOCK) position and remove the firstcoded
keyfrom the ignition.
4. Within ten seconds of turning the ignition to the 1 (LOCK) position,
insert the second previouslycoded keyinto the ignition.

INFORMATION ABOUT UNIFORM TIRE QUALITY GRADING
Tire Quality Grades apply to new
pneumatic passenger car tires.
The Quality grades can be found
where applicable on the tire sidewall
between tread shoulder and
maximum section width.
For example:
•Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic passenger car tires.
They do not apply to deep tread, winter-type snow tires, space-saver or
temporary use spare tires, light truck or “LT” type tires, tires with
nominal rim diameters of 10 to 12 inches or limited production tires as
defined in Title 49 Code of Federal Regulations Part 575.104(c)(2).
U.S. Department of Transportation-Tire quality grades:The U.S.
Department of Transportation requires Ford Motor Company to give you
the following information about tire grades exactly as the government
has written it.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C.
The grades represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor traction
performance.

•kPa:Kilopascal, a metric unit of air pressure.
•PSI:Pounds per square inch, a standard unit of air pressure.
•Cold inflation pressure:The tire pressure when the vehicle has
been stationary and out of direct sunlight for an hour or more and
prior to the vehicle being driven for 1 mile (1.6 km).
•Recommended inflation pressure:The cold inflation pressure found
on the Safety Compliance Certification Label or Tire Label located on
the B-Pillar or the edge of the driver’s door.
•B-pillar:The structural member at the side of the vehicle behind the
front door.
•Bead area of the tire:Area of the tire next to the rim.
•Sidewall of the tire:Area between the bead area and the tread.
•Tread area of the tire:Area of the perimeter of the tire that
contacts the road when mounted on the vehicle.
•Rim:The metal support (wheel) for a tire or a tire and tube assembly
upon which the tire beads are seated.
INFLATING YOUR TIRES
Safe operation of your vehicle requires that your tires are properly
inflated. Remember that a tire can lose up to half of its air pressure
without appearing flat.
Every day before you drive, check your tires. If one looks lower than the
others, use a tire gauge to check pressure of all tires and adjust if
required.
At least once a month and before long trips, inspect each tire and check
the tire pressure with a tire gauge (including spare, if equipped). Inflate
all tires to the inflation pressure recommended by Ford Motor Company.
Use a tire gauge to check the tire inflation pressure, including the spare
(if equipped), at least monthly and before long trips. You are strongly
urged to buy a reliable tire pressure gauge, as automatic service station
gauges may be inaccurate. Ford recommends the use of a digital or
dial-type tire pressure gauge rather than a stick-type tire pressure gauge.
Use the recommended cold inflation pressure for optimum tire
performance and wear. Under-inflation or over-inflation may cause
uneven treadwear patterns.

Note:If you have to drive a distance to get air for your tire(s), check
and record the tire pressure first and add the appropriate air pressure
when you get to the pump. It is normal for tires to heat up and the air
pressure inside to go up as you drive.
2. Remove the cap from the valve on one tire, then firmly press the tire
gauge onto the valve and measure the pressure.
3. Add enough air to reach the recommended air pressure.
Note:If you overfill the tire, release air by pushing on the metal stem in
the center of the valve. Then recheck the pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire, including the spare.
Note:Some spare tires operate at a higher inflation pressure than the
other tires. For T-type/mini-spare tires (seeDissimilar Spare
Tire/Wheel Informationsection for description): Store and maintain at
60 psi (4.15 bar). For Full Size and Dissimilar spare tires (see
Dissimilar Spare Tire/Wheel Informationsection for description):
Store and maintain at the higher of the front and rear inflation pressure
as shown on the Tire Label.
6. Visually inspect the tires to make sure there are no nails or other
objects embedded that could poke a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts or bulges.
TIRE CARE
Inspecting your tires
Periodically inspect the tire treads for uneven or excessive wear and
remove objects such as stones, nails or glass that may be wedged in the
tread grooves. Check for holes or cuts that may permit air leakage from
the tire and make necessary repairs. Also inspect the tire sidewalls for
cracking, cuts, bruises and other signs of damage or excessive wear. If
internal damage to the tire is suspected, have the tire demounted and
inspected in case it needs to be repaired or replaced. For your safety,
tires that are damaged or show signs of excessive wear should not be
used because they are more likely to blow out or fail.
