2. Pick up the latch plate, and run the lap and shoulder portions of
the vehicle's safety belt through
or around the restraint. The child
restraint instructions will show
you how.
3. For H3T models, tilt the latchplate to adjust the belt if needed.
4. Push the latch plate into thebuckle until it clicks.

Seats and Restraints 3-61
6. To tighten the belt, push downon the child 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. 7. 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)
on page 3‑51for more
information.
For H3T models, if the headrest
interferes with the installation of
the child restraint, remove the
headrest by pressing the button
on the headrest post, at the
top of the seatback, and lift to
remove. Store the headrest
under the outboard side of the
rear seat.
8. Push and pull the child restraint in different directions to be sure
it is secure.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it. If the
headrest has been removed,
reinsert it onto the seatback.
Securing Child Restraints
(Rear Center Seating
Position)
Many child restraints are too wide to
be correctly secured in the center
rear seat, although some of them
will fit there. If the center seat
position is too narrow for the child
restraint, secure it in a rear outside
seat position.
If a child restraint is secured in the
center seat position, follow the
instructions in Securing Child
Restraints (Rear Outboard Seating
Position)
on page 3‑59or Securing
Child Restraints (Rear Center
Seating Position)
on page 3‑61or
Securing Child Restraints (Right
Front Seat Position) on page 3‑62.

3-62 Seats and Restraints
Securing Child Restraints
(Right Front Seat
Position)
The vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
SeeWhere to Put the Restraint
on
page 3‑49.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right front
passenger frontal airbag under
certain conditions. See Passenger
Sensing System
on page 3‑35and Passenger Airbag Status
Indicatoron page 5‑11for more
information, including important
safety information.
A label on the sun visor says,
“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 right
front passenger 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 right front
passenger airbag inflates and the
passenger seat is in a forward
position.
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though it is
turned off.
(Continued)
WARNING (Continued)
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 right front seat, always move
the front passenger seat as far
back as it will go. It is better to
secure the child restraint in a
rear seat.
SeePassenger Sensing System
on page 3‑35for additional
information.
If the child restraint has the LATCH
system, see Lower Anchors and
Tethers for Children (LATCH
System)
on page 3‑51for how and
where to install the child restraint
using LATCH. If a child restraint is
secured using a safety belt and it
uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System)
on page 3‑51for
top tether anchor locations.

Seats and Restraints 3-63
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 strap
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.
You will be using the lap-shoulder
belt to secure the child restraint in
this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as itwill go before securing the
forward-facing child restraint.
When the passenger sensing
system has turned off the
right front passenger frontal
airbag, the off indicator on
the passenger airbag status
indicator should light and stay
lit when the vehicle is started.
See Passenger Airbag Status
Indicator on page 5‑11. 2. Put the child restraint on
the seat.
3. Pick up the latch plate, and run the lap and shoulder portions of
the vehicle's safety belt through
or around the restraint. The child
restraint instructions will show
you how.
4. Push the latch plate into thebuckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
5. Pull the rest of the shoulder beltall the way out of the retractor to
set the lock.

6. To tighten the belt, push downon the child 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.
7. Push and pull the child restraint in different directions to be sure
it is secure. If the airbag is off, the off indicator
in the passenger airbag status
indicator will come on and stay on
when the vehicle is started.
If a child restraint has been
installed and the on indicator is lit,
see
“If the On Indicator is Lit for a
Child Restraint ”under Passenger
Sensing System
on page 3‑35for
more information.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.

9-32 Driving and Operating
Similar appearing vehicles may
have different GVWRs and
capacity weights. Please note
the vehicle's Certification/Tire
label or consult your dealer for
additional details.
{WARNING
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
If you do, parts on the vehicle
can break, and it can change
the way the vehicle handles.
These could cause you to
lose control and crash. Also,
overloading can shorten the
life of the vehicle. Using heavier suspension
components to get added
durability might not change
the weight ratings. Ask your
dealer to help you load the
vehicle the right way.Notice :Overloading the
vehicle may cause damage.
Repairs would not be covered
by the vehicle warranty. Do
not overload the vehicle.
If you put things inside your
vehicle –like suitcases,
tools, packages, or anything
else –they will go as fast as the
vehicle goes. If you have to stop
or turn quickly, or if there is a
crash, they will keep going.
{WARNING
Things you put inside your
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the cargo
area of your vehicle. Try to
spread the weight evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint
in your vehicle.
.When you carry something
inside the vehicle, secure
it whenever you can.
.Do not leave a seat folded
down unless you need to.
