FORWARD-FACING CHILD
RESTRAINT INSTALLATION
USING LATCH
For additional information, see “Child safety”
(P. 1-20) and “Child restraints” (P. 1-22) be-
fore installing a child restraint.
Do not use the lower anchors if the combined
weight of the child and the child restraint
exceeds 65 lbs. (29.5 kg). If the combined
weight of the child and the child restraint is
greater than 65 lbs. (29.5 kg), use the vehi-
cle's seat belt (not the lower anchors) to in-
stall the child restraint. Be sure to follow the
child restraint manufacturer's instructions for
installation.
Follow these steps to install a forward-
facing child restraint in the rear seats using
the LATCH system:
1. Position the child restraint on the seat. Always follow the child restraint manu-
facturer's instructions. 2. Secure the child restraint anchor attach-
ments to the LATCH lower anchors.
Check to make sure the LATCH attach-
ment is properly attached to the lower
anchors.
If the child restraint is equipped with a top
tether strap, route the top tether strap
and secure the tether strap to the tether
anchor point. For additional information,
see “Installing top tether strap” (P. 1-37).
Do not install child restraints that require
the use of a top tether strap in seating
positions that do not have a top tether
anchor. 3. The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
child restraint fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the child re-
straint is removed. For additional infor-
mation, see “Head restraints/headrests”
(P. 1-7).

FORWARD-FACING CHILD
RESTRAINT INSTALLATION
USING THE SEAT BELTS
WARNING
The three-point seat belt with Automatic
Locking Retractor (ALR) must be used
when installing a child restraint. Failure to
use the ALR mode will result in the child
restraint not being properly secured. The
restraint could tip over or be loose and
cause injury to a child in a sudden stop or
collision. Also, it can change the operation
of the front passenger air bag. For addi-
tional information, see “Front passenger
air bag and status light” (P. 1-51). For additional information, see “Child safety”
(P. 1-20) and “Child restraints” (P. 1-22) be-
fore installing a child restraint.
Do not use the lower anchors if the combined
weight of the child and the child restraint
exceeds 65 lbs. (29.5 kg). If the combined
weight of the child and the child restraint is
greater than 65 lbs. (29.5 kg), use the vehi-
cle's seat belt (not the lower anchors) to in-
stall the child restraint. Be sure to follow the
child restraint manufacturer's instructions for
installation.
Follow these steps to install a forward-facing
child restraint using the vehicle seat belt in the
rear seats or in the front passenger seat:
1.
If you must install a child restraint in the
front seat, it should be placed in a
forward-facing direction only. Move the
seat to the rearmost position. Child re-
straints for infants must be used in the
rear-facing direction and, therefore,
must not be used in the front seat.
2. Position the child restraint on the seat. Always follow the child restraint manu-
facturer’s instructions.
The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
child restraint fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the child re-
straint is removed. For additional infor-
mation, see “Head restraints/headrests”
(P. 1-7).
If the seating position does not have an
adjustable head restraint/headrest and it
is interfering with the proper child re-
straint fit, try another seating position or a
different child restraint.

3. Route the seat belt tongue through thechild restraint and insert it into the buckle
until you hear and feel the latch engage.
Be sure to follow the child restraint manu-
facturer’s instructions for belt routing.
If the child restraint is equipped with a top
tether strap, route the top tether strap
and secure the tether strap to the tether
anchor point (rear seat installation only).
For additional information, see “Installing
top tether strap” (P. 1-26).
Do not install child restraints that require the
use of a top tether strap in seating positions
that do not have a top tether anchor.
4. Pull the shoulder belt until the belt is fully extended. At this time, the seat belt re-
tractor is in the ALR mode (child restraint
mode). It reverts to ELR mode when the
seat belt is fully retracted. 5. Allow the seat belt to retract. Pull up on
the shoulder belt to remove any slack in
the belt.

6. Remove any additional slack from the seatbelt; press downward and rearward firmly
in the center of the child restraint with
your knee to compress the vehicle seat
cushion and seatback while pulling up on
the seat belt.
7. Tighten the tether strap according to the manufacturer's instructions to remove
any slack. 8. After attaching the child restraint, test it
before you place the child in it. Push it
from side to side while holding the child
restraint near the seat belt path. The child
restraint should not move more than 1
inch (25 mm), from side to side. Try to tug
it forward and check to see if the belt
holds the restraint in place. If the restraint
is not secure, tighten the seat belt as nec-
essary, or put the restraint in another seat
and test it again. You may need to try a
different child restraint. Not all child re-
straints fit in all types of vehicles. 9. Check to make sure the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 2
through 8.

WARNING
Child restraint anchorages are designed to
withstand only those loads imposed by
correctly fitted child restraints. Under no
circumstances are they to be used to attach
adult seat belts, or other items or equip-
ment to the vehicle. Doing so could damage
the child restraint anchorages. The child re-
straint will not be properly installed using
the damaged anchorage, and a child could
be seriously injured or killed in a collision.

3. The booster seat should be positioned onthe vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
booster seat fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the booster
seat is removed. For additional informa-
tion, see “Head restraints/headrests”
(P. 1-7). If the seating position does not have an
adjustable head restraint/headrest and it
is interfering with the proper booster seat
fit, try another seating position or a differ-
ent booster seat.
4. Position the lap portion of the seat belt low and snug on the child’s hips. Be sure to
follow the booster seat manufacturer’s
instructions for adjusting the seat belt
routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up extra
slack. Be sure the shoulder belt is posi-
tioned across the top, middle portion of
the child’s shoulder. Be sure to follow the
booster seat manufacturer’s instructions
for adjusting the seat belt routing.
6. Follow the warnings, cautions and in- structions for properly fastening a seat
belt shown in “Three-point type seat belt
with retractor” (P. 1-15). 7. If the booster seat is installed in the front
passenger seat, place the ignition switch
in the ON position. The front passenger air
bag status light
may or may not
illuminate, depending on the size of the
child and the type of booster seat being
used. For additional information, see
“Front passenger air bag and status light”
(P. 1-51).

Front passenger air bag
The front passenger air bag and passenger
knee air bag is designed to automatically turn
OFF when the vehicle is operated under
some conditions as described below in accor-
dance with U.S. regulations. If the front pas-
senger air bag and passenger knee air bag is
OFF, it will not inflate in a crash. The driver air
bag and other air bags in your vehicle are not
part of this system.
The purpose of the regulation is to help re-
duce the risk of injury or death from an inflat-
ing air bag to certain front passenger seat
occupants, such as children, by requiring the
air bag to be automatically turned OFF. Cer-
tain sensors are used to meet the
requirements.
The occupant classification sensor in this ve-
hicle is a weight sensor. It is designed to
detect an occupant and objects on the seat
by weight. For example, if a child is in the
front passenger seat, the INFINITI Advanced
Air Bag System is designed to turn the front
passenger air bag OFF in accordance with
the regulations. Also, if a child restraint of the
type specified in the regulations is on the
seat, its weight and the child’s weight can be
detected and cause the air bag to turn OFF.Front passenger seat adult occupants who
are properly seated and using the seat belt as
outlined in this manual should not cause the
front passenger air bag to be automatically
turned OFF. For small adults it may be turned
OFF, however, if the occupant takes his/her
weight off the seat cushion (for example, by
not sitting upright, by sitting on an edge of
the seat, or by otherwise being out of posi-
tion), this could cause the sensor to turn the
air bag OFF. Always be sure to be seated and
wearing the seat belt properly for the most
effective protection by the seat belt and
supplemental air bag.
INFINITI recommends that pre-teens and
children be properly restrained in a rear seat.
INFINITI also recommends that appropriate
child restraints and booster seats be properly
installed in a rear seat. If this is not possible,
the occupant classification sensor is designed
to operate as described above to turn the
front passenger air bag and passenger knee
air bag OFF for specified child restraints as
required by the regulations. Failing to prop-
erly secure child restraints and to use the ALR
mode may allow the restraint to tip or move
in a collision or sudden stop. This can also
result in the front passenger air bag and pas-
senger knee air bag inflating in a crash in-
stead of being OFF. For additional informa-
tion, see “Child restraints” (P. 1-22).If the front passenger seat is not occupied,
the front passenger air bag and passenger
knee air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because
of the object’s weight detected by the occu-
pant classification sensor. Other conditions
could also result in air bag inflation, such as if
a child is standing on the seat, or if two
children are on the seat, contrary to the in-
structions in this manual. Always be sure that
you and all vehicle occupants are seated and
restrained properly.
Using the front passenger air bag status light,
you can monitor when the front passenger air
bag and passenger knee air bag is automati-
cally turned OFF.
If an adult occupant is in the seat but the
front passenger air bag status light is illumi-
nated (indicating that the front passenger air
bag and passenger knee air bag is OFF), it
could be that the person is a small adult, or is
not sitting on the seat properly or not using
the seat belt properly.
If a child restraint must be used in the front
seat, the front passenger air bag status light
may or may not be illuminated, depending on
the size of the child and the type of child
restraint being used. If the air bag status light
is not illuminated (indicating that the front
