98 SEATS AND RESTRAINTS
Securing Child Restraints
(With the Safety Belt in the
Rear Seat)
When securing a child restraint in a
rear seating 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, seeLower Anchors and Tethers
for Children (LATCH System) 091 for
how and where to install the child
restraint using LATCH. If a child
restraint is secured in the vehicle
using a safety belt and it uses a top
tether, see Lower Anchors and Tethers
for Children (LATCH System) 091 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 strap must
be anchored.
If the child restraint or vehicle seat
position does not have the LATCH
system, you will be using the safety 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 090.
{Warning
The power seats will work with the
ignition off. Children could operate
the power seats and be injured.
Never leave children alone in the
vehicle.
Caution
Do not adjust the power seat when
a child restraint is installed.
Adjusting the seat may cause
damage to the installed child
restraint. Use the window lockout
button on the driver door to
prevent adjustment of the seat
whenever a child restraint is
installed. If the rear seat is adjustable, make
sure the rear seat is positioned fully
rearward before installing a child
restraint.
1. Put the child restraint on the seat.
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. Push the latch plate into thebuckle until it clicks.

SEATS AND RESTRAINTS 99
Position the release button on
the buckle, away from the child
restraint system, so that the
safety belt could be quickly
unbuckled if necessary.
4. Pull the shoulder belt all the wayout of the 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 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.
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) 091.
7. Before placing a child in the child restraint, make sure it is
securely held in place. 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.
Securing Child Restraints
(With the Safety 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 090.

100 SEATS AND RESTRAINTS
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the front
outboard passenger frontal airbag and
knee airbag under certain conditions.
SeePassenger Sensing System 079 and
Passenger Airbag Status Indicator 0126
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
(Continued)
Warning (Continued)
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 airbag(s), no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag(s) are off.
Secure rear-facing child restraints
in a rear seat, even if the airbag(s)
are 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 079
for additional information. If the child restraint uses a top tether,
see
Lower Anchors and Tethers for
Children (LATCH System) 091 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 strap must
be anchored.
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.
When the passenger sensing
system has turned off the front
outboard passenger frontal
airbag and knee airbag, the off
indicator on the passenger airbag
status indicator should light and

7. Before placing a child in thechild restraint, make sure it is
securely held in place. Refer to
your child restraint manufacturer
instructions.
If the airbags are 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 079.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
