{CAUTION:
Children can be seriously injured or strangled
if a shoulder belt is wrapped around their neck
and the safety belt continues to tighten.
Secure any unused safety belts behind the
child restraint so children cannot reach them.
Pull the shoulder belt all the way out of the
retractor to set the lock, if your vehicle has
one, after the child restraint has been installed.
Be sure to follow the instructions of the child
restraint manufacturer.Notice:Contact between the child restraint LATCH
attachment parts and the vehicle’s safety belt
assembly may cause damage to these parts.
Make sure when securing unused safety belts
behind the child restraint that there is no contact
between the child restraint LATCH attachment parts
and the vehicle’s safety belt assembly.
Folding an empty rear seat with the safety belts
secured may cause damage to the safety belt or the
seat. When removing the child restraint, always
remember to return the safety belts to their normal,
stowed position before folding the rear seat.

1.5. Return the rear passenger side seatback to its
upright position. You may have to move the
child restraint to a temporary position to do
this. Ensure that the seatback locks and the
safety belt is routed properly. Then lower the
seat cushion until the seatback and the seat
cushion lock into position.
2. Attach 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 safety belts. 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. Attach and tighten the lower attachments on
the child restraint to the lower anchors.3. Tighten the top tether.
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
push and pull on the seatback to be sure it is
locked.
4. Push and pull the child restraint in different
directions to be sure it is secure.

If your vehicle has roof-rail airbags and a third row
passenger seat, the airbags are located in the ceiling
above the rear windows for the outboard passenger
positions in the third row.
{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating airbag must be kept clear. Do not put
anything between an occupant and an airbag,
and do not attach or put anything on the
steering wheel hub or on or near any other
airbag covering.
If your vehicle has roof-rail airbags, never
secure anything to the roof of your vehicle by
routing the rope or tie down through any door
or window opening. If you do, the path of an
inating roof-rail airbag will be blocked. Driver Side shown, Passenger Side similar
1-68

The parts of the airbag that come into contact with you
may be warm, but not too hot to touch. There may
be some smoke and dust coming from the vents in the
deated airbags. Airbag ination does not prevent
the driver from seeing out of the windshield or being
able to steer the vehicle, nor does it prevent people from
leaving the vehicle.
{CAUTION:
When an airbag inates, there may be dust in
the air. This dust could cause breathing
problems for people with a history of asthma or
other breathing trouble. To avoid this, everyone
in the vehicle should get out as soon as it is
safe to do so. If you have breathing problems
but cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a window
or a door. If you experience breathing problems
following an airbag deployment, you should
seek medical attention.Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and turn
the hazard warning ashers on when the airbags inate.
You can lock the doors, turn the interior lamps off,
and turn the hazard warning ashers off by using the
controls for those features.
In many crashes severe enough to inate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger airbag.Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for the
airbag system. If you do not get them, the airbag
system will not be there to help protect you in another
crash. A new system will include airbag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
Your vehicle has a crash sensing and diagnostic
module which records information after a crash.
SeeVehicle Data Recording and Privacy on
page 7-16andEvent Data Recorders on page 7-16.
Let only qualied technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer/retailer for service.
