If you need to secure more than one child
restraint in the rear seat, seeWhere to Put
the Restraint 069.
1. Put the child restraint on the seat.
2. Attach and tighten the lower attachments to the lower anchors. If the
child restraint does not have lower
attachments or the desired seating
position does not have lower anchors,
secure the child restraint with the top
tether and the seat belt. Refer to your
child restraint manufacturer instructions
and the instructions in this manual.
2.1. Find the lower anchors for the desired seating position.
2.2. To access the lower anchors in the second row, it may help to recline
the seatback.
Third row seatbacks must be
upright before placing the child
restraint on the seat.
2.3. Put the child restraint on the seat.
2.4. Attach and tighten the lower attachments on the child restraint
to the lower anchors. If necessary, adjust the angle of the
second row seatback to achieve a
tight installation. Make sure the
second row bench seatbacks are
aligned at the same angle.
3. If the child restraint manufacturer recommends that the top tether be
attached, adjust the top tether to its full
length and attach it to the anchor. Refer
to the child restraint instructions and the
following steps:
3.1. Find the top tether anchor.
3.2. Route, attach, and tighten the top tether according to your child
restraint instructions and the
following instructions:
If the position you are using does
not have a head restraint and you
are using a single tether, route the
tether over the seatback.
If the position you are using does
not have a head restraint and you
are using a dual tether, route the
tether over the seatback.
If the position you are using has an
adjustable headrest or head
restraint, adjust it accordingly to
allow proper fitment. If you are
using a single tether, route the
tether in between the headrest or
head restraint posts.

76 Seats and Restraints
If the position you are using has an
adjustable headrest or head
restraint, adjust it accordingly to
allow proper fitment. If you are
using a dual tether, route the
tether around the headrest or head
restraint posts.
If the child restraint is installed next
to a center seat, make sure the top
tether does not interfere with the
center seating position shoulder
belt/retractor. If it does, find
another suitable seating position to
install the child restraint.If the position you are using has a
fixed head restraint and you are
using a single tether, route the
tether under the head restraint and
in between the head restraint posts
or around the outboard side of the
head restraint.
If the position you are using has a
fixed head restraint and you are
using a dual tether, route the
tether around the head restraint.
If the child restraint is installed next
to a center seat, make sure the top
tether does not interfere with the
center seating position shoulder
belt/retractor. If it does, find
another suitable seating position to
install the child restraint.
4. Before placing a child in the child restraint, make sure it is securely held in
place. To check, grasp the child restraint
at the LATCH path and attempt to move
it side to side and back and forth. There
should be no more than 2.5 cm (1 in) of
movement, for proper installation.
Replacing LATCH System Parts
After a Crash
{Warning
A crash can damage the LATCH system in
the vehicle. A damaged LATCH system
may not properly secure the child
restraint, resulting in serious injury or
even death in a crash. To help make sure

Seats and Restraints 77
Warning (Continued)
the LATCH system is working properly
after a crash, see your dealer to have the
system inspected and any necessary
replacements made as soon as possible.
If the vehicle has the LATCH system and it
was being used during a crash, new LATCH
system parts may be needed.
New parts and repairs may be necessary
even if the LATCH system was not being
used at the time of the crash.
Securing Child Restraints (With
the Seat Belt in the Rear Seat)
The vehicle is equipped with a front center
airbag in the inboard side of the driver seat.
Even with a front center airbag, a child
restraint can be installed in any second row
seating position. If you install a child
restraint in a second row center seat, move
the second row seat to the rearward
position, whenever possible, to minimize
contact with the front center airbag. 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.
If the child restraint has the LATCH system,
see
Lower Anchors and Tethers for Children
(LATCH System) 070 for how and where to
install the child restraint using LATCH. If a
child restraint is secured in the vehicle using
a seat belt and it uses a top tether, see
Lower Anchors and Tethers for Children
(LATCH System) 070 for top tether anchor
locations.
Do not secure a child seat in a position
without a top tether anchor if a national or
local law requires that the top tether be
anchored, or if the instructions that come
with the child restraint say that the top
tether must be anchored.
In Canada, the law requires that
forward-facing child restraints have a top
tether, and that the tether be attached.
If the child restraint or vehicle seat position
does not have the LATCH system, you will
be using the seat belt to secure the child
restraint. Be sure to follow the instructions
that came with the child restraint. If more than one child restraint needs to be
installed in the rear seat, be sure to read
Where to Put the Restraint
069.
1. Put the child restraint on the seat.
2. Pick up the latch plate and run the lap and shoulder portions of the vehicle seat
belt through or around the child
restraint. Ensure the seat belt webbing is
routed as directly as possible and is not
caught on seat handles or plastic trim.
The child restraint instructions will show
you how.
3. Push the latch plate into the buckle untilit clicks.

78 Seats and Restraints
Position the release button on the
buckle, away from the child restraint, so
that the seat belt could be quickly
unbuckled if necessary.
There must not be direct contact of the
child restraint to the push button.
4. Pull the shoulder belt all the way out ofthe retractor to set the lock. When the
retractor lock is set, the belt can be
tightened but not pulled out of the
retractor.
5. To tighten the belt, push down on thechild restraint, pull the shoulder portion
of the belt to tighten the lap portion of
the belt, and feed the shoulder belt back
into the retractor. When installing a
forward-facing child restraint, it may be
helpful to use your knee to push down
on the child restraint as you tighten
the belt.
Try to pull the belt out of the retractor
to make sure the retractor is locked.
If the retractor is not locked, repeat
Steps 4 and 5. 6. If the child restraint has a top tether,
follow the child restraint manufacturer's
instructions regarding the use of the top
tether. See Lower Anchors and Tethers
for Children (LATCH System) 070.
7. Before placing a child in the child restraint, make sure it is securely held in
place. To check, grasp the child restraint
at the seat belt path and attempt to
move it side to side and back and forth.
When the child restraint is properly
installed, there should be no more than
2.5 cm (1 in) of movement.
To remove the child restraint, unbuckle the
vehicle seat belt and let it return to the
stowed position. If the top tether is attached
to a top tether anchor, disconnect it.
Securing Child Restraints (With
the Seat Belt in the Front Seat)
This vehicle has airbags. A rear seat is a
safer place to secure a forward-facing child
restraint. See Where to Put the Restraint
0 69.
In addition, the vehicle has a passenger
sensing system which is designed to turn off
the front outboard passenger frontal airbag

16411536) - 2023 - CRC - 3/28/22
Seats and Restraints 79
under certain conditions. SeePassenger
Sensing System 059 and
Passenger Airbag Status Indicator 0104 for
more information, including important
safety information.
Never put a rear-facing child seat in the
front. This is because the risk to the
rear-facing child is so great, if the airbag
deploys.
{Warning
A child in a rear-facing child restraint can
be seriously injured or killed if the front
outboard passenger frontal airbag
inflates. This is because the back of the
rear-facing child restraint would be very
close to the inflating airbag. A child in a
forward-facing child restraint can be
seriously injured or killed if the front
outboard passenger frontal airbag inflates
and the passenger seat is in a forward
position.
Even if the passenger sensing system has
turned off the front outboard passenger
frontal airbag, no system is fail-safe. No
(Continued)
Warning (Continued)
one can guarantee that an airbag will not
deploy under some unusual circumstance,
even though it is turned off.
Secure rear-facing child restraints in a
rear seat, even if the airbag is off. If you
secure a forward-facing child restraint in
the front outboard passenger seat,
always move the seat as far back as it
will go. It is better to secure the child
restraint in a rear seat.
SeePassenger Sensing System 059 for
additional information.
If the child restraint uses a top tether, see
Lower Anchors and Tethers for Children
(LATCH System) 070 for top tether anchor
locations.
Do not secure a child seat in a position
without a top tether anchor if a national or
local law requires that the top tether be
anchored, or if the instructions that come
with the child restraint say that the top
tether must be anchored.
In Canada, the law requires that
forward-facing child restraints have a top
tether, and that the tether be attached. When using the lap-shoulder belt to secure
the child restraint in this position, follow the
instructions that came with the child
restraint and the following instructions:
1. Move the seat as far back as it will go before securing the forward-facing child
restraint. Move the seat upward or the
seatback to an upright position,
if needed, to get a tight installation of
the child restraint. There must be finger
clearance between the push button and
the child restraint.
When the passenger sensing system has
turned off the front outboard passenger
frontal airbag, the OFF indicator on the
passenger airbag status indicator should
light and stay lit when you start the
vehicle. See Passenger Airbag Status
Indicator 0104.
2. Put the child restraint on the seat.
3. Pick up the latch plate and run the lap and shoulder portions of the vehicle seat
belt through or around the restraint.
Ensure the seat belt webbing is routed
as direct as possible and is not caught
on seat handles or plastic trim. The child
restraint instructions will show you how.

86 Storage
Roof Rack System
The vehicle may be equipped with side-rails
for a roof rack system. Cargo must be
secured with properly installed cross rails
and other accessories designed to carry
cargo. These can be purchased from your
dealer.
{Warning
Before driving and occasionally during a
trip, check that cargo is securely fastened,
rests evenly between the cross rails and
does not block the vehicle's lamps or
windows. Never load cargo directly on
the roof of the vehicle or allow cargo to
hang over the rear or sides of the vehicle.
Never load cargo without first properly
installing cross rails and other accessories
designed to carry cargo. Personal injury,
death or damage to the vehicle or other
property may occur.
If driving for a long distance, on rough
roads, or at high speeds, occasionally stop
the vehicle to make sure the cargo remains
in its place.
Cargo Weight Limits
Do not exceed the maximum cargo weight
for the roof rack system, including the
weight of the cross rails and any other
accessories used to carry the cargo such
as bike racks or roof boxes. The maximum
cargo weight that can be loaded onto the
roof rack system is 100 kg (220 lb) or the
weight designated in the instructions that
came with the cross rails or other roof rack
accessories, whichever is less.
{Warning
Never load the roof rack with more
weight than specified in this section.
Loading cargo on the roof rack will make
the vehicle's center of gravity higher. To
avoid losing control of the vehicle, avoid
overloading, high speeds, sudden starts,
sharp turns, sudden braking, or abrupt
maneuvers when carrying cargo on the
roof rack. The weight of any cargo carried on the roof
rack system must be included in calculating
the loaded weight of the vehicle. Do not
exceed the maximum vehicle capacity when
loading the vehicle, including cargo carried
on the roof rack system and passengers and
cargo carried in the vehicle. For more
information on vehicle capacity and loading,
see
Vehicle Load Limits 0195.
