48 Seats and Restraints
Second Row Seats
The vehicle's second row seats
have head restraints in the outboard
seating positions that cannot be
adjusted.
The second row seat outboard head
restraints are not removable.
Third Row Seats
The third row seat head restraint
can be lowered to allow for better
visibility when the rear seat is
unoccupied.To lower the head restraint, press
the button located on the top of the
seatback and push the head
restraint down.
Return the lowered head restraint to
the upright position until it locks into
place. Push and pull on the head
restraint to make sure it is locked.
If you are installing a child restraint
in the third row seat, see
“Securing
a Child Restraint Designed for the
LATCH System” underLower
Anchors and Tethers for Children
(LATCH System) 093.
Front Seats
Center Seat
If equipped, the center front
seatback doubles as an armrest and
cupholder/storage area for the driver
and passenger when the center
front seat is not used. Do not use it
as a seating position when the
seatback is folded down.
Power Seat Adjustment
{Warning
You can lose control of the
vehicle if you try to adjust a driver
seat while the vehicle is moving.
Adjust the driver seat only when
the vehicle is not moving.

Canada/Mexico-13566587) - 2020 - CRC - 4/15/19
Seats and Restraints 91
Booster Seats
A belt-positioning booster seat is
used for children who have
outgrown their forward-facing child
restraint. Boosters are designed to
improve the fit of the vehicle's seat
belt system until the child is large
enough for the vehicle seat belts to
fit properly without a booster seat.
See the seat belt fit test in Older
Children 086.
Securing an Add-On Child
Restraint in the Vehicle
{Warning
A child can be seriously injured or
killed in a crash if the child
restraint is not properly secured in
the vehicle. Secure the child
restraint properly in the vehicle
using the vehicle seat belt or
LATCH system, following the
instructions that came with that
child restraint and the instructions
in this manual.
To help reduce the chance of injury,
the child restraint must be secured
in the vehicle. Child restraints must
be secured in vehicle seats by lap
belts or the lap belt portion of a
lap-shoulder belt, or by the LATCH
system. See Lower Anchors and
Tethers for Children (LATCH
System) 093 for more information.
Children can be endangered in a
crash if the child restraint is not
properly secured in the vehicle. When securing an add-on child
restraint, refer to the following:
1. Instruction labels provided on the child restraint
2. Instruction manual provided with the child restraint
3. This vehicle owner's manual
The child restraint instructions are
important, so if they are not
available, obtain a replacement
copy from the manufacturer.
Keep in mind that an unsecured
child restraint can move around in a
collision or sudden stop and injure
people in the vehicle. Be sure to
properly secure any child restraint in
the vehicle —even when no child is
in it.
In some areas Certified Child
Passenger Safety Technicians
(CPSTs) are available to inspect
and demonstrate how to correctly
use and install child restraints. In
the U.S., refer to the National
Highway Traffic Safety
Administration (NHTSA) website to
locate the nearest child safety seat

Canada/Mexico-13566587) - 2020 - CRC - 4/15/19
Seats and Restraints 93
{Warning
A child in a child restraint in the
center front seat can be badly
injured or killed by the frontal
airbags if they inflate. Never
secure a child restraint in the
center front seat. It is always
better to secure a child restraint in
a rear seat.
Do not use child restraints in the
center front seat position.
When securing a child restraint with
the seat belts in a rear seat position,
study the instructions that came with
the child restraint to make sure it is
compatible with this vehicle.
Child restraints and booster seats
vary considerably in size, and some
may fit in certain seating positions
better than others. Depending on where you place the
child restraint and the size of the
child restraint, you may not be able
to access adjacent seat belts or
LATCH anchors for additional
passengers or child restraints.
Adjacent seating positions should
not be used if the child restraint
prevents access to or interferes with
the routing of the seat belt.
Wherever a child restraint is
installed, be sure to follow the
instructions that came with the child
restraint and secure the child
restraint properly.
Keep in mind that an unsecured
child restraint can move around in a
collision or sudden stop and injure
people in the vehicle. Be sure to
properly secure any child restraint in
the vehicle
—even when no child is
in it.
Lower Anchors and
Tethers for Children
(LATCH System)
The LATCH system secures a child
restraint during driving or in a crash.
LATCH attachments on the child
restraint are used to attach the child
restraint to the anchors in the
vehicle. The LATCH system is
designed to make installation of a
child restraint easier.
In order to use the LATCH system in
your vehicle, you need a child
restraint that has LATCH
attachments. LATCH-compatible
rear-facing and forward-facing child
seats can be properly installed
using either the LATCH anchors or
the vehicle’ s seat belts. Do not use
both the seat belts and the LATCH
anchorage system to secure a
rear-facing or forward-facing
child seat.

Canada/Mexico-13566587) - 2020 - CRC - 4/15/19
94 Seats and Restraints
Booster seats use the vehicle’s seat
belts to secure the child and the
booster seat. If the manufacturer
recommends that the booster seat
be secured with the LATCH system,
this can be done as long as the
booster seat can be positioned
properly and there is no interference
with the proper positioning of the
lap-shoulder belt on the child.Make sure to follow the instructions
that came with the child restraint,
and also the instructions in this
manual.
When installing a child restraint with
a top tether, you must also use
either the lower anchors or the seat
belts to properly secure the child
restraint. A child restraint must
never be installed using only the top
tether and anchor.For a forward-facing 5-pt harness
child restraint where the combined
weight of the child and restraint are
up to 29.5 kg (65 lb), use either the
lower LATCH anchorages with the
top tether anchorage, or the seat
belt with the top tether anchorage.
Where the combined weight of the
child and restraint are greater than
29.5 kg (65 lb), use the seat belt with
the top tether anchorage only.

specific child weight up to which the
LATCH system can be used to
install the restraint.
The following explains how to attach
a child restraint with these
attachments in the vehicle.
Not all vehicle seating positions
have lower anchors. In this case,
the seat belt must be used (with top tether where available) to secure
the child restraint. See

96 Seats and Restraints
Lower Anchors
Lower anchors (1) are metal bars
built into the vehicle. There are two
lower anchors for each LATCH
seating position that will
accommodate a child restraint with
lower attachments (2).
Top Tether Anchor
A top tether (3,4) is used to secure
the top of the child restraint to the
vehicle. A top tether anchor is built
into the vehicle. The top tether
attachment hook (2) on the child
restraint connects to the top tether
anchor in the vehicle in order to
reduce the forward movement and
rotation of the child restraint during
driving or in a crash.The child restraint may have a
single tether (3) or a dual tether (4).
Either will have a single attachment
hook (2) to secure the top tether to
the anchor.
Some child restraints with top
tethers are designed for use with or
without the top tether being
attached. Others require the top
tether always to be attached. In
Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached. Be sure to read and follow
the instructions for your child
restraint.

anchor symbol is on the flipper
panel.
Second Row Seat—Bucket
For models with bucket second row
seating, the top tether anchors are
at the bottom rear of the seat
cushion for each seating position in
the second row. Be sure to use an
anchor located directly behind the
seating position where the child
restraint will be placed.Second Row Seat —60/40
For models with 60/40 second row
seating, the top tether anchors are
at the bottom rear of the seat
cushion for each seating position in
the second row. Be sure to use an
anchor located directly behind the
seating position where the child
restraint will be placed.

Third Row Seat
For the third row seat, the top tether
anchors are on the back of the
seatback. Move the flipper panel
rearward to access the anchors. Be
sure to use an anchor located
directly behind the seating position
where the child restraint will be
placed.
Do not secure a child restraint in a
position without a top tether anchor
if a national or local law requires
that the top tether be attached, or if
the instructions that come with the
child restraint say that the top tether
must be attached. According to accident statistics,
children and infants are safer when
properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position. See
Where to Put the
Restraint 092 for additional
information.
Securing a Child Restraint
Designed for the LATCH
System
{Warning
A child could be seriously injured
or killed in a crash if the child
restraint is not properly attached
to the vehicle using either the
LATCH anchors or the vehicle
seat belt. Follow the instructions
that came with the child restraint
and the instructions in this
manual.
{Warning
To reduce the risk of serious or
fatal injuries during a crash, do
not attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment
to come loose or even break
during a crash. A child or others
could be injured.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
