Second-row bench seats and third-row
passenger side
The LATCH anchors are at the rear section
of the rear seat between the cushion and
seatback below the symbols as shown.
Follow the child restraint manufacturer's
instructions to properly install a child
restraint with LATCH attachments.
Follow the instructions on attaching child
safety seats with tether straps. See Using
Tether Straps later in this chapter.
Attach LATCH lower attachments of the
child restraint only to the anchors shown. Use of Inboard Lower Anchors from the
Outboard Seating Positions (Center
Seating Use) WARNING
The standardized spacing for LATCH
lower anchors is 11 in (280 mm)
center to center. Do not use LATCH
lower anchors for the center seating
position unless the child restraint
manufacturer's instructions permit and
specify using anchors spaced at least as
far apart as those in this vehicle. The lower anchors at the center of the
second row bench seat are spaced 20.5 in
(52 cm)
apart. The standardized spacing
for LATCH lower anchors is 11 in (28 cm)
center to center. You cannot install a child
restraint with rigid LATCH attachments at
the center seating position. You can only
use LATCH compatible child restraints
(with attachments on belt webbing) at
this seating position provided that the child
restraint manufacturer ’s instructions
permit use with the anchor spacing stated.
Do not attach a child restraint to any lower
anchor if an adjacent child restraint is
attached to that anchor.
Each time you use the safety seat, check
that the seat is properly attached to the
lower anchors and tether anchor, if
applicable. Tug the child restraint from side
to side and forward and back where it is
secured to your vehicle. The seat should
move less than one inch when you do this
for a proper installation.
If the safety seat is not anchored properly,
the risk of a child being injured in a crash
greatly increases.

against the occupant’
s body when
activated. This helps increase the
effectiveness of the seatbelts. In frontal
crashes, the seatbelt pretensioners can be
activated alone or, if the crash is of
sufficient severity, together with the front
airbags.
FASTENING THE SEATBELTS
Standard belts shown, inflatable belts
similar
The front outboard and rear safety
restraints in the vehicle are combination
lap and shoulder belts. 1. Insert the belt tongue into the proper
buckle (the buckle closest to the
direction the tongue is coming from)
until you hear a click and feel it latch.
Make sure you securely fasten the
tongue in the buckle. 2. To unfasten, press the release button
and remove the tongue from the
buckle.
Using Seatbelts During Pregnancy WARNING
Always ride and drive with your
seatback upright and properly fasten
your seatbelt. Fit the lap portion of
the seatbelt snugly and low across the
hips. Position the shoulder portion of the
seatbelt across your chest. Pregnant
women must follow this practice. See the
following figure. 35

PASSIVE ANTI-THEFT
SYSTEM
Note:
The 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: Metallic objects, electronic devices
or a second coded key on the same key
chain may cause vehicle starting problems
if they are too close to the key when starting
the engine. Prevent these objects from
touching the coded key while starting the
engine. Switch the ignition off, move all
objects on the key chain away from the
coded key and restart the engine if a
problem occurs.
Note: Do not leave a duplicate coded key
in the vehicle. Always take your keys and
lock all doors when leaving the vehicle.
SecuriLock®
The system is an engine immobilization
system. It is designed to help prevent the
engine from being started unless a coded
key programmed to your vehicle is used.
Using the wrong key may prevent the
engine from starting. A message may
appear in the information display.
If you are unable to start the engine with a
correctly coded key, a malfunction has
happened and a message may appear in
the information display.
Automatic Arming
The vehicle arms immediately after you
switch the ignition off.
Automatic Disarming
Switching the ignition on with a coded key
disarms the vehicle. Replacement Keys
Note:
Your vehicle comes equipped with
two integrated keyhead transmitters or two
intelligent access keys.
The integrated keyhead transmitter
functions as a programmed ignition key
that operates all the locks and starts the
vehicle, as well as a remote control.
The intelligent access key functions as a
programmed key that operates the driver
door lock and activates the intelligent
access with push button start system, as
well as a remote control.
If your programmed transmitters or
standard SecuriLock coded keys
(integrated keyhead transmitters only) are
lost or stolen and you do not have an extra
coded key, you will need to have your
vehicle towed to an authorized dealer. You
need to erase the key codes from your
vehicle and program new coded keys.
Store an extra programmed key away from
the vehicle in a safe place to help prevent
any inconveniences. See your authorized
dealer to purchase additional spare or
replacement keys.
Programming a Spare Integrated
Keyhead Transmitter
Note: You can program a maximum of eight
coded keys to your vehicle. All eight can be
integrated keyhead transmitters.
You can program your own integrated
keyhead transmitter or standard
SecuriLock coded keys to your vehicle. This
procedure will program both the engine
immobilizer keycode and the remote entry
portion of the remote control to your
vehicle
Only use integrated keyhead transmitters
or standard SecuriLock keys.

and removing the previously
programmed coded key, insert the new
unprogrammed key into the ignition.
8. Switch the ignition from off to on. Keep
the ignition on for at least six seconds.
9. Remove the newly programmed coded
key from the ignition.
If the key has been successfully
programmed it will start the engine and
operate the remote entry system (if the
new key is an integrated keyhead
transmitter).
If programming was not successful, wait
10 seconds and repeat Steps 1 through 8.
If you are still unsuccessful, take your
vehicle to your authorized dealer. Programming a Spare Intelligent
Access Key
See your authorized dealer to have
additional keys programmed to your
vehicle.
ANTI-THEFT ALARM
The system will warn you of an
unauthorized entry to your vehicle. It will
be triggered if any door, the luggage
compartment or the hood is opened
without using the key, remote control or
keyless entry keypad.
The direction indicators will flash and the
horn will sound if unauthorized entry is
attempted while the alarm is armed.
Take all remote controls to an authorized
dealer if there is any potential alarm
problem with your vehicle.
Arming the Alarm
The alarm is ready to arm when there is
not a key in your vehicle. Electronically lock
your vehicle to arm the alarm.

actions:
•
Unlock the doors or luggage
compartment with the remote control
or keyless entry keypad.

Third Row Seat Exit
1. Pull on the strap on the back of the
second row seat. This folds the
seatback forward. Pull the strap a
second time to tumble the seat
forward, allowing easy exit from the
third row seat. Note: You must fold the
seatback flat in order to release the
floor latches. Make sure that there are
no objects on the seat cushion that
may restrict the seatback from folding
flat. 2.
To return the seatback to the floor from
the tumbled position, rotate the seat
down until you hear it latching to the
floor. 3.
Lift the seatback toward the rear of the
vehicle, and rotate the seatback until
you hear a click, locking it in the upright
position. Note:
The seatback will not
raise if the rear latch hooks are not
properly engaged to the floor striker. If
the seatback does not raise, then
repeat steps 3 and 4. 4.
Make sure that the rear latch hooks are
properly engaged with the floor striker.
Note: Make sure that the seat and seatback
are latched securely in position. Keep floor
area free of objects that would prevent
proper seat engagement.
