102 SEATS AND RESTRAINTS
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)
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, seeLower Anchors and Tethers
for Children (LATCH System) 095 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) 095 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.
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 094.
1. Put the child restraint on the seat.
For outboard rear seat positions,
put the head restraint in the
upright position. See Head
Restraints 053. 2. Pick up the latch plate, and run
the lap and shoulder portions of
the vehicle's seat belt through or
around the restraint. The child
restraint instructions will show
you how.
3. Push the latch plate into thebuckle until it clicks.
Position the release button on
the buckle, away from the child
restraint, so that the seat 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) 095.
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.

104 SEATS AND RESTRAINTS
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 Restraint094.
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.
See Passenger Sensing System 082 and
Passenger Airbag Status Indicator 0130
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
(Continued)
Warning (Continued)
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 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,(Continued)
Warning (Continued)
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 082
for additional information.
If the vehicle does not have a rear seat
that will accommodate a rear-facing
child restraint, a rear-facing child
restraint should not be installed in the
vehicle, even if the airbag is off.
If the child restraint uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) 095 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.

SEATS AND RESTRAINTS 105
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.
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
stay lit when you start the
vehicle. See Passenger Airbag
Status Indicator 0130.
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 seat belt through or
around the restraint. The child
restraint instructions will show
you how.
Tilt the latch plate to adjust the
belt if needed.
4. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle, away from the child
restraint, so that the seat belt
could be quickly unbuckled if
necessary.

5. 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.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.
Try to pull the belt out of the
retractor to make sure the
retractor is locked. If the
retractor is not locked, repeat
Steps 5 and 6. 7. If the vehicle does not have a
rear seat and the child restraint
manufacturer recommends using
a top tether anchor, attach the
top tether to the top tether
anchor. Refer to the instructions
that came with the child
restraint and to Lower Anchors
and Tethers for Children (LATCH
System) 095.
8. 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.
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 082.

normally, the indicator light turns off.
For vehicles with the reconfigurable
cluster, this light may not come on
when the engine is started.
If the light stays on and the engine
does not start, there could be a
problem with the theft-deterrent
system. SeeImmobilizer Operation
