WARNING:Depending on where you secure a child restraint,
and depending on the child restraint design, you may block
access to certain safety belt buckle assemblies and/or LATCH lower
anchors, rendering those features potentially unusable. To avoid risk of
injury, occupants should only use seating positions where they are able
to be properly restrained.
Use of inboard lower anchors from the outboard seating positions
(center seating use)
The lower anchors at the center of the second row rear seat are spaced
520 mm (20.5 inches) apart. The standardized spacing for LATCH lower
anchors is 280 mm (11 inches) center to center. A child seat with rigid
LATCH attachments cannot be installed at the center seating position.
LATCH compatible child seats (with attachments on belt webbing) can
only be used at this seating position provided that the child seat
manufacturer’s instructions permit use with the anchor spacing stated.
Do not attach a child seat to any lower anchor if an adjacent child seat is
attached to that anchor.
WARNING:The standardized spacing for LATCH lower anchors
is 280 mm (11 inches) center to center. Do not use LATCH
lower anchors for the center seating position unless the child seat
manufacturer’s instructions permit and specify using anchors spaced at
least as far apart as those in this vehicle.
If you install a child seat with rigid LATCH attachments, do not tighten
the tether strap enough to lift the child seat off the vehicle seat cushion
when the child is seated in it. Keep the tether strap just snug without
lifting the front of the child seat. Keeping the child seat just touching the
vehicle seat gives the best protection in a severe crash.
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 seat from side to side and forward and back where it is secured to
the 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.

Combining safety belt and LATCH lower anchors for attaching
child safety seats
When used in combination, either the safety belt or the LATCH lower
anchors may be attached first, provided a proper installation is achieved.
Attach the tether strap afterward, if included with the child seat. Refer
toRecommendations for attaching child safety restraints for children
in this chapter.
Attaching child safety seats with tether straps
Many forward-facing child safety seats include a tether strap which
extends from the back of the child safety seat and hooks to an anchoring
point called the top tether anchor. Tether straps are available as an
accessory for many older safety seats. Contact the manufacturer of your
child seat for information about ordering a tether strap, or to obtain a
longer tether strap if the tether strap on your safety seat does not reach
the appropriate top tether anchor in the vehicle.
The rear seats of your vehicle are equipped with built-in tether strap
anchors located behind the seats as described below.
The tether strap anchors in your vehicle are in the following positions
(shown from top view):
•40/40 second row seats and
third-row passenger side
•60/40 second row seats and
third-row passenger side
Attach the tether strap only to the appropriate tether anchor as shown.
The tether strap may not work properly if attached somewhere other
than the correct tether anchor.

Once the child safety seat has been installed, using either the safety belt,
the lower anchors of the LATCH system, or both, you can attach the top
tether strap.
Perform the following steps to attach a child safety seat to the tether
anchor:
1. Route the child safety seat tether
strap over the back of the seat.
Lift the head restraint to its full-up
position (refer toHead restraints
underRear seatsin this chapter).
Route the child safety seat tether
strap over the back of the seat,
under the head restraint, and
between the head restraint posts.
Leave the head restraint in the
full-up position.
2. Locate the correct anchor for the selected rear seating position.

Note: The cargo tie-downs at the
rear edge of the floor are not
tether anchors.
3. Clip the tether strap to the
anchor as shown.
If the tether strap is clipped incorrectly, the child safety seat may not be
retained properly in the event of a collision.
4. Tighten the child safety seat tether strap according to the
manufacturer’s instructions.
If the safety seat is not anchored properly, the risk of a child being
injured in a collision greatly increases.
If your child restraint system is equipped with a tether strap, and the
child restraint manufacturer recommends its use, Ford also recommends
its use.

Child booster seats
The belt-positioning booster (booster seat) is used to improve the fit of
the vehicle safety belt. Children outgrow a typical child seat (e.g.,
convertible or toddler seat) when they weigh about 40 lb (18 kg) and are
around four (4) years of age. Consult your child safety seat owner guide
for the weight, height, and age limits specific to your child safety seat.
Keep your child in the child safety seat if it properly fits the child,
remains appropriate for their weight, height and age AND if properly
secured to the vehicle.
Although the lap/shoulder belt will provide some protection, children
who have outgrown a typical child seat are still too small for lap/shoulder
belts to fit properly, and wearing an improperly fitted vehicle safety belt
could increase the risk of serious injury in a crash. To improve the fit of
both the lap and shoulder belt on children who have outgrown child
safety seats, Ford Motor Company recommends use of a belt-positioning
booster.
Booster seats position a child so that vehicle lap/shoulder safety belts fit
better. They lift the child up so that the lap belt rests low across the hips
and the knees bend comfortably at the edge of the cushion, while
minimizing slouching. Booster seats may also make the shoulder belt fit
better and more comfortably. Try to keep the belt near the middle of the
shoulder and across the center of the chest. Moving the child closer (a
few centimeters or inches) to the center of the vehicle, but remaining in
the same seating position, may help provide a good shoulder belt fit.
When children should use booster seats
Children need to use booster seats from the time they outgrow the
toddler seat until they are big enough for the vehicle seat and
lap/shoulder belt to fit properly. Generally this is when they reach a
height of at least 4 feet 9 inches (1.45 meters) tall (around age eight to
age twelve and between 40 lb (18 kg) and 80 lb (36 kg) or upward to
100 lb (45 kg) if recommended by your child restraint manufacturer).
Many state and provincial laws require that children use approved
booster seats until they reach age eight, a height of 4 feet 9 inches
(1.45 meters) tall, or 80 lb (36 kg).

Booster seats should be used until you can answer YES to ALL of these
questions when seated without a booster seat:
•Can the child sit all the way back
against the vehicle seat back with
knees bent comfortably at the
edge of the seat cushion?
•Can the child sit without
slouching?
•Does the lap belt rest low across the hips?
•Is the shoulder belt centered on the shoulder and chest?
•Can the child stay seated like this for the whole trip?
Types of booster seats
There are generally two types of belt-positioning booster seats: backless
and high back. Always use booster seats in conjunction with the vehicle
lap/shoulder belt.
•Backless booster seats
If your backless booster seat has a
removable shield, remove the
shield. If a vehicle seating position
has a low seat back or no head
restraint, a backless booster seat
may place your child’s head (as
measured at the tops of the ears)
above the top of the seat. In this
case, move the backless booster
to another seating position with a
higher seat back or head restraint and lap/shoulder belts, or consider
using a high back booster seat.

•High back booster seats
If, with a backless booster seat,
you cannot find a seating position
that adequately supports your
child’s head, a high back booster
seat would be a better choice.
Children and booster seats vary in size and shape. Choose a booster that
keeps the lap belt low and snug across the hips, never up across the
stomach, and lets you adjust the shoulder belt to cross the chest and
rest snugly near the center of the shoulder. The drawings below compare
the ideal fit (center) to a shoulder belt uncomfortably close to the neck
and a shoulder belt that could slip off the shoulder. The drawings below
also show how the lap belt should be low and snug across the child’s
hips.

If the booster seat slides on the vehicle seat, placing a rubberized mesh
sold as shelf or carpet liner under the booster seat may improve this
condition. Do not introduce any item thicker than this under the booster
seat. Check with the booster seat manufacturer’s instructions.
The importance of shoulder belts
Using a booster without a shoulder belt increases the risk of a child’s
head hitting a hard surface in a collision. For this reason, you should
never use a booster seat with a lap belt only. It is generally best to use a
booster seat with lap/shoulder belts in the back seat.
Move a child to a different seating location if the shoulder belt does not
stay positioned on the shoulder during use.
Follow all instructions provided by the manufacturer of the booster seat.
WARNING:Never place, or allow a child to place, the shoulder
belt under a child’s arm or behind the back because it reduces
the protection for the upper part of the body and may increase the risk
of injury or death in a collision.
