WARNING:
Riding with a reclined seatback in-
creases your chance of serious or fatal
injuries in the event of a collision or
sudden stop. The protection of your
restraint system (seat belts and airbags)
is greatly reduced by reclining your seat.
Seat belts must be snug against your
hips and chest to work properly. The
more the seatback is reclined, the greater
the chance that an occupant's hips will
slide under the lap belt or the occupant's
neck will strike the shoulder belt. Drivers
and passengers should always sit well
back in their seats, properly belted, and
with the seatbacks upright.
B080E01CM-AATHeadrestThe driver's and front passenger's seats
are equipped with a headrest for the
occupant's safety and comfort.
The headrest not only provides comfort for
the driver and front passenger, but also
helps protect the head and neck in the
event of a collision.

WARNING:
o For maximum effectiveness in case
of an accident, the headrest should be
adjusted so the middle of the head-
rest is at the same height of the center
of gravity of an occupant's head. Gen-
erally, the center of gravity of most
people's head is similar with the height
of the top of their eyes. Also, adjust
the headrest as close to your head as
possible. For this reason, the use of a
cushion that holds the body away from
the seatback is not recommended.

WARNING:
The purpose of the folding rear
seatbacks is to allow you to carry longer
objects than could otherwise be
accommodated. Do not allow
passengers to sit on top of the folded
down seatback, while the car is moving
as this is not a proper seating position
and no seat belts are available for use.
This could result in serious injury or
death in case of an accident or sudden
stop. Objects carried on the folded down
seatback should not extend higher than
the top of the front seats. This could allow
cargo to slide forward and cause injury
or damage during sudden stops.
B110A01NF-GATFOLDING REAR SEATBACKSo To unlock the seatback, pull the
seatback release lever, then pull for-
ward on the seatback panel.
o When you return the seatback to its
upright position, always be sure it has
locked into position by pulling and
pushing on the top of the seatback.

!For vehicles with adjustable headrests,
route the tether strap under the head-
rest and between the headrest posts,
otherwise route the tether strap over the
top of the seatback.
3. Connect the tether strap hook to the
child restraint hook holder and tighten
to secure the seat.
WARNING:
o A child can be seriously injured or
killed in a collision if the child restraint
is not properly anchored. Always
follow the child seat manufacturer’s
instructions for installation and use.
o Never mount more than one child re-
straint to a single tether or to a single
lower anchorage point. The increased
load caused by multiple seats may
cause the tethers or anchorage points
to break, causing serious injury or
death.
B230D06E-AATSecuring the Child Restraint Seat
with the "Child Seat Lower Anchor"
systemSome child seat manufacturers make safety
seats that are labeled as LATCH or LATCH-
compatible child seats. LATCH stands for
"Lower anchors and Tethers for Children".
These seats include two rigid or webbing
mounted attachments that connect to two
LATCH anchors at specific seating posi-
tions in your vehicle. This type of child seat
eliminates the need to use seat belts to
attach the child seat. LATCH anchors have
been provided in your vehicle. The LATCH
anchors are located in the left and right
outboard rear seating positions. Their loca-
tions are shown in the illustration. There is
no LATCH anchor provided for the center
rear seating position.

WARNING:
o A child can be seriously injured or
killed in a collision if the child restraint
is not properly anchored. Always
follow the child seat manufacturer’s
instructions for installation and use.
o Never install a child restraint using
the LATCH lower anchors at the cen-
ter position of the rear seat. In a
crash, the LATCH lower anchors may
break if a car seat is improperly placed
in the center position resulting in se-
rious or fatal injuries. Only place a
LATCH or LATCH-compatible child
seat in the left or right out-board rear
seating positions (as shown) to the
appropriate LATCH anchors pro-
vided.
o Never mount more than one child
restraint to a single tether or to a
single lower anchorage point. The
increased load caused by multiple
seats may cause the tethers or
anchorage points to break, causing
serious injury or death.
