3To install a child restraint system on the
outboard or center rear seats, do the fol-
lowing:
1. Place the child restraint system in the
seat and route the lap/shoulder belt
around or through the restraint, follow-
ing the restraint manufacturer’s
instructions. Be sure the seat belt web-
bing is not twisted.
2. Fasten the lap/shoulder belt latch into the buckle. Listen for the distinct “click”
sound.Position the release button so that it iseasy to access in case of an emergency.
3. Pull the shoulder portion of the seat belt all the way out. When the shoulder
portion of the seat belt is fully extend-
ed, it will shift the retractor to the
“Aautomatic locking” (child restraint)
mode. 4. Slowly allow the shoulder portion of
the seat belt to retract and listen for an
audible “clicking” or “ratcheting” sound.
This indicates that the retractor is in
the “automatic locking” mode. If no dis-
tinct sound is heard, repeat steps 3
and 4.

5. Remove as much slack from the beltas possible by pushing down on the
child restraint system while feeding the
shoulder belt back into the retractor.
6. Push and pull on the child restraint system to confirm that the seat belt is
holding it firmly in place. If it is not,
release the seat belt and repeat steps
2 through 6.
7. Double check that the retractor is in the “Automatic locking” mode by attempt-
ing to pull more of the seat belt out of
the retractor. If you cannot, the retractor
is in the “Automatic locking” mode.
To remove the child restraint, press the
release button on the buckle and then
pull the lap/shoulder belt out of the
restraint and allow the seat belt to retract
fully. When the seat belt is allowed to
retract to its fully stowed position, the
retractor will automatically switch
from the “Automatic locking” mode to
the emergency lock mode for normal
adult usage.
Securing a child restraint seat with
“Tether Anchor” system Child restraint hook holders are located
on the package tray.
OEN036104
WARNING
- Automatic locking mode
The lap/shoulder belt automatically
returns to the “emergency lock
mode” whenever the belt is allowed
to retract fully. Therefore, the pre-
ceding seven steps must be fol-
lowed each time a child restraint is
installed.
If the retractor is not in the
Automatic Locking mode, the child
restraint can move when your vehi-
cle turns or stops suddenly. A child
can be seriously injured or killed if
the child restraint is not properly
anchored to the car, including set-
ting the retractor to the Automatic
Locking mode.

31. Route the child restraint seat strap
over the seatback.
For vehicles with adjustable head-
rests, route the tether strap under the
headrest and between the headrest
posts, otherwise route the tether strap
over the top of the seatback.
2. Connect the tether strap hook to the appropriate child restraint hook holder
and tighten to secure the child restraint
seat.

WARNING
- Child restraintcheck
Check that the child restraint sys-
tem is secure by pushing and
pulling it in different directions.
Incorrectly fitted child restraints
may swing, twist, tip or separate
causing death or serious injury.
WARNING
- Tether strap
Never mount more than one child
restraint to a single tether anchor
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.
WARNING
A child can be seriously injured or
killed in a collision if the child
restraint is not properly anchored
to the car and the child is not prop-
erly restrained in the child restraint.
Always follow the child seat manu-
facturer’s instructions for installa-
tion and use.
WARNING - Child restraint anchorage
 Child restraint anchorages are
designed to withstand only those
loads imposed by correctly fitted
child restraints. Under no circum-
stances are they to be used for
adult seat belts or harnesses or
for attaching other items or
equipment to the vehicle.
 The tether strap may not work properly if attached somewhere
other than the correct tether
anchor.

Securing a child restraint seat withchild seat lower anchor systemSome child seat manufacturers make
child restraint seats that are labeled as
LATCH or LATCH-compatible child
restraint 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
positions in your vehicle. This type of
child restraint seat eliminates the need to
use seat belts to attach the child seat in
the rear seats. Child restraint symbols are located on
the left and right rear seat backs to indi-
cate the position of the lower anchors for
child restraints.

WARNING
 When using the vehicle's "LATCH" system to install a child
restraint system in the rear seat,
all unused vehicle rear seat belt
metal latch plates or tabs must be
latched securely in their seat belt
buckles and the seat belt web-
bing must be retracted behind
the child restraint to prevent the
child from reaching and taking
hold of unretracted seat belts.
Unlatched metal latch plates or
tabs may allow the child to reach
the unretracted seat belts which
may result in strangulation and a
serious injury or death to the
child in the child restraint.
 Do not place anything around the lower anchors. Also make sure
that the seat belt is not caught in
the lower anchors.

Safety features of your vehicle36
3LATCH anchors have been provided in
your vehicle. The LATCH anchors are
located in the left and right outboard rear
seating positions. Their locations are
shown in the illustration. There is no
LATCH anchor provided for the center
rear seating position.
The LATCH anchors are located between
the seatback and the seat cushion of the
rear seat left and right outboard seating
positions.
Follow the child seat manufacturer’s
instructions to properly install child
restraint seats with LATCH or LATCH-
compatible attachments.
Once you have installed the LATCH child
restraint, assure that the seat is properly
attached to the LATCH and tether
anchors.
Also, test the child restraint seat before
you place the child in it. Tilt the seat from
side to side. Also try to tug the seat for-
ward. Check to see if the anchors hold
the seat in place.
WARNING
If the child restraint is not anchored
properly, the risk of a child being
seriously injured or killed in a colli-
sion greatly increases.
WARNING -
LATCH lower
anchors
LATCH lower anchors are only to
be used with the left and right rear
outboard seating positions. Never
attempt to attach a LATCH
equipped seat in the center seating
position. You may damage the
anchors or the anchors may fail
and break in a collision.
CAUTION
Do not allow the rear seat belt web-
bing to get scratched or pinched bythe child-seat latch and LATCHanchor during the installation.

AIR BAG - ADVANCED SUPPLEMENTAL RESTRAINT SYSTEM
OYF039050N
* The actual air bags in the vehicle may differ from the illustration.
WARNING
Even in vehicles with air bags, you
and your passengers must always
wear the seat belts provided in
order to minimize the risk and
severity of injury in the event of a
collision or rollover.

Safety features of your vehicle38
3How does the air bag system
operate  Air bags are activated (able to inflate if
necessary) only when the ignition
switch is turned to the ON or START
position.
 Air bags inflate instantly in the event of serious frontal or side collision in order
to help protect the occupants from seri-
ous physical injury.
 There is no single speed at which the air bags will inflate.
Generally, air bags are designed to
inflate by the severity of a collision and
its direction. These two factors deter-
mine whether the sensors sendout an
electronic deployment/ inflation signal.
 Air bag deployment depends on a number of factors including vehicle
speed, angles of impact and the densi-
ty and stiffness of the vehicles or
objects which your vehicle hits in the
collision. Though, factors are not limit-
ed to those mentioned above.
 The front air bags will completely inflate and deflate in an instant.
It is virtually impossible for you to see
the air bags inflate during an accident. It is much more likely that you will sim-
ply see the deflated air bags hanging
out of their storage compartments after
the collision.
 In order to help provide protection in a severe collision, the air bags must
inflate rapidly. The speed of air bag
inflation is a consequence of the
extremely short time in which a collision
occurs and the need to get the air bag
between the occupant and the vehicle
structures before the occupant impacts
those structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries in a severe collision
and is thus a necessary part of air bag
design.
However, air bag inflation can also
cause injuries which normally can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
 There are even circumstances under which contact with the air bag
can cause fatal injuries, especially if
the occupant is positioned exces-
sively close to the air bag.
WARNING
 To avoid severe personal injuryor death caused by deploying air
bags in a collision, the driver
should sit as far back from the
steering wheel air bag as possi-
ble (at least 10 inches (250 mm)
away). The front passengers
should always move their seats
as far back as possible and sit
back in their seat.
 Air bags inflate instantly in the event of collision, and passen-
gers may be injured by the air bag
expansion force if they are not in
proper position.
 Air bag inflation may cause injuries which normally include
facial or bodily abrasions,
injuries from broken glasses or
burns by the air bag inflation
gasses.

339
Safety features of your vehicle
Noise and smokeWhen the air bags inflate, they make a
loud noise and they leave smoke and
powder in the air inside of the vehicle.
This is normal and is a result of the igni-
tion of the air bag inflator. After the air
bag inflates, you may feel substantial dis-
comfort in breathing due to the contact of
your chest with both the seat belt and the
air bag, as well as from breathing the
smoke and powder.Open your doors
and/or windows as soon as possible
after impact in order to reduce dis-
comfort and prevent prolonged expo-
sure to the smoke and powder.
Though the smoke and powder are non-
toxic, they may cause irritation to the skin
(eyes, nose and throat, etc). If this is the
case, wash and rinse with cold water
immediately and consult a doctor if the
symptom persists.
Do not install a child restraint on the
front passenger’s seat.Never place a rear-facing child restraint
in the front passenger’s seat. If the air
bag deploys, it would impact the rear-fac-
ing child restraint, causing serious or
fatal injury.
In addition, do not place front-facing child
restraints in the front passenger’s seat
either. If the front passenger air bag
inflates, it could cause serious or fatal
injuries to the child.
1JBH3051
WARNING
When the air bags deploy, the air
bag related parts in the steering
wheel and/or instrument panel
and/or in both sides of the roof rails
above the front and rear doors are
very hot. To prevent injury, do not
touch the air bag storage area’s
internal components immediately
after an air bag has inflated.
WARNING
 Extreme Hazard! Do not use a rearward facing child restraint on
a seat protected by an air bag in
front of it!
 Never put a child restraint in the front passenger’s seat. If the front
passenger air bag inflates, it
would cause serious or fatal
injuries.
 When children are seated in the rear outboard seats of a vehicle
equipped with side air bags, be
sure to install the child restraint
system as far away from the door
side as possible, and securely
lock the child restraint system in
position.
Inflation of side and/or curtain air
bags could cause serious injury
or death to an infant or child.
