provide additional cargo space.
To ip and fold the seat(s), do the following:
1. Pull up on the loop located where the seat cushion
meets the seatback and ip the seat cushion
forward.Notice:Folding a rear seat with the safety belts
still fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts
and return them to their normal stowed position
before folding a rear seat.
2. Lift the lever, located
on the outboard side of
the seatback, and
fold the seatback
forward.
The head restraint will automatically fold out of the
way as the seatback is folded down.

4. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the safety
belt through the latch plate to fully tighten the
lap belt on smaller occupants.To unlatch the belt, push the button on the buckle. The
belt should return to its stowed position.
Before a door is closed, be sure the safety belt is out of
the way. If a door is slammed against a safety belt,
damage can occur to both the belt and the vehicle.

{CAUTION:
Do not attach more than one child restraint to a
single anchor. Attaching more than one child
restraint to a single anchor could cause the anchor
or attachment to come loose or even break during
a crash. A child or others could be injured. To
reduce the risk of serious or fatal injuries during a
crash, attach only one child restraint per anchor.
{CAUTION:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Buckle 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.Notice:Do not let the LATCH attachments rub
against the vehicle’s safety belts. This may damage
these parts. If necessary, move buckled safety
belts to avoid rubbing the LATCH attachments.
Do not fold the empty rear seat with a safety belt
buckled. This could damage the safety belt or
the seat. Unbuckle and return the safety belt to its
stowed position, before folding the seat.
1. Attach and tighten 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.
1.1. Find the lower anchors for the desired
seating position.
1.2. Pull the strap at the center of the seat where
the seat cushion meets the seatback. This
will allow you to fold the seat cushion up and
out of the way. Lift the ap to expose the
anchors and then lower the seat cushion.
SeeRear Seat Operation on page 1-11
for additional information. Be sure the
cushion is locked into place.
1.3. Put the child restraint on the seat.
1.4. Attach and tighten the lower attachments on
the child restraint to the lower anchors.

5. To tighten the belt, push down on 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.6. If the child restraint has a top tether, follow the child
restraint manufacturer’s instructions regarding the
use of the top tether. SeeLower Anchors and
Tethers for Children (LATCH) on page 1-43for more
information.
7. 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 a Child Restraint in the
Center Rear Seat Position
Many child restraints are too wide to be correctly
secured in the center rear seat, although some of them
will t there. If the center seat position is too narrow
for your child restraint, secure it in a rear outside seat
position.
If you secure a child restraint in the center seat position,
follow the instructions inSecuring a Child Restraint in
a Rear Outside Seat Position on page 1-49.

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 1-64for more information.
To remove the child restraint, unbuckle the vehicle
safety belt and let it return to the stowed position.
Airbag System
The vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.
A roof-rail airbag for the driver and the passenger
seated directly behind the driver.
A roof-rail airbag for the right front passenger and
the passenger seated directly behind the right
front passenger.All of the airbags in your vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word AIRBAG will appear on the
middle part of the steering wheel for the driver and
on the instrument panel for the right front passenger.
With roof-rail airbags, the word AIRBAG will appear
along the headliner or trim.
Airbags are designed to supplement the protection
provided by safety belts. Even though today’s airbags
are also designed to help reduce the risk of injury
from the force of an inating bag, all airbags must inate
very quickly to do their job.
1-55

How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the
impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. Roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.
Rollover capable roof-rail airbags are designed to help
contain the head and chest of occupants in the
outboard seating positions in the rst and second rows.
The rollover capable roof-rail airbags are designed to
help reduce the risk of full or partial ejection in rollover
events, although no system can prevent all such
ejections.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-60for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
What Will You See After an Airbag
Inates?
After the frontal airbags inate, they quickly deate,
so quickly that some people may not even realize an
airbag inated. Roof-rail airbags may still be at least
partially inated for some time after they deploy. Some
components of the airbag module may be hot for
several minutes. For location of the airbag modules,
seeWhat Makes an Airbag Inflate? on page 1-61.
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.
