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 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 3-33 for additional
information.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) on page 3-47 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.
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.
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 on page 5-19.
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.
Tilt the latch plate to adjust the
belt, if needed.

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 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. Before placing a child in thechild restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
safety 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 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” underPassenger Sensing
System on page 3-33 for more
information.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.

Power Outlet 110 Volt
Alternating Current
If equipped with this power outlet, it
can be used to plug in electrical
equipment that uses a maximum
limit of 150 watts.
For vehicles with a center console,
the 110 volt power outlet is on the
rear of the center console.
For vehicles with bench seats, the
110 volt power outlet is on the
center stack below the climate
controls.
The 110 volt power outlet is on the
rear of the center console.
An indicator light on the outlet turns
on to show it is in use. The light
comes on when the ignition is in
ON/RUN, equipment requiring less
than 150 watts is plugged into the
outlet, and no system fault is
detected.The indicator light does not come on
when the ignition is in LOCK/OFF or
if the equipment is not fully seated
into the outlet.
If equipment is connected using
more than 150 watts or a system
fault is detected, a protection circuit
shuts off the power supply and the
indicator light turns off. To reset the
circuit, unplug the item and plug it
back in or turn the ignition off and
then back to ON/RUN. The power
restarts when equipment using 150
watts or less is plugged into the
outlet and a system fault is not
detected.

properly if they are plugged in:.Equipment with high initial peak
wattage, such as
compressor-driven refrigerators
and electric power tools.
