3rd row bench seat
Installing top tether strap
WARNING
In the 3rd row bench seat, a child
restraint with a top tether strap can
only be used in the center position. Do
not place in an outboard seating position
and attempt to angle the tether strap to
the center position.
First, secure the child restraint with the seat
belt. 1. If necessary, raise or remove the head
restraint or headrest to position the top
tether strap over the top of the seatback.
If the head restraint or headrest is
removed, store it in a secure place. Be
sure to reinstall the head restraint or
headrest when the child restraint is
removed. See “Head restraints/head-
rests” (P.1-13) for head restraint or
headrest adjustment, removal and in-
stallation information.
2. Secure the tether strap to the tether anchor point on the back of each seat-
back (2nd row seat) or on the floor (3rd
row seat) behind the child restraint.
3. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack. Make sure the head restraint
or headrest does not contact the top
tether strap.
If you have any questions when installing a
top tether strap on the rear seat, it is
recommended you visit an INFINITI retailer
for this service.
BOOSTER SEATS
Precautions on booster seats
WARNING
If a booster seat and seat belt are not
used properly, the risk of a child being
injured in a sudden stop or collision
greatly increases:
. Make sure the shoulder portion of
the belt is away from the child’s face
and neck and the lap portion of the
belt does not cross the stomach.
. Make sure the shoulder belt is not
behind the child or under the child’s
arm.
. A booster seat must only be installed
in a seating position that has a lap/
shoulder belt.

Booster seat installation
CAUTION
Do not use the lap/shoulder belt Auto-
matic Locking Retractor (ALR) mode
when using a booster seat with the seat
belts.
Refer to all Warnings and Cautions in the
“Child safety”, “Child restraints” and “Boos-
ter seats” sections earlier in this section
before installing a child restraint.
Follow these steps to install a booster seat in
the rear seat or in the front passenger seat:
SSS0640
1. If you must install a booster seat in the
front seat, move the seat to the rear-
most position.
2. Position the booster seat on the seat. Only place it in a forward-facing direc-
tion. Always follow the booster seat
manufacturer’s instructions.
LRS0454
Front passenger position
3. The booster seat should be positioned on the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint or headrest to obtain the
correct booster seat fit. If the head
restraint or headrest is removed, store
it in a secure place. Be sure to reinstall
the head restraint or headrest when the
booster seat is removed. See “Head
restraints/headrests” (P.1-13) for head
restraint or headrest adjustment, re-
moval and installation information.
If the seating position does not have an
adjustable head restraint or a headrest
and it is interfering with the proper

indicate that the front passenger air bag
is operational.
In addition to the above, certain objects
placed on the front passenger seat may also
cause the light to operate as described
above depending on their weight.
For additional information related to the
normal operation and troubleshooting of
this occupant classification sensor system,
please refer to “Normal operation” (P.1-62)
and “Troubleshooting” (P.1-62) in this sec-
tion.
Front passenger air bag:
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below as permitted by U.S. regula-
tions. If the front passenger 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
reduce the risk of injury or death from an
inflating air bag to certain front passenger
seat occupants, such as children, by requiring
the air bag to be automatically turned OFF.
The occupant classification sensors (weight
sensors) are on the seat cushion frame under
the front passenger seat and are designed to
detect an occupant and objects on the seat.
For example, if a child is in the front passenger seat, the Advanced Air Bag
System is designed to turn the passenger
air bag OFF in accordance with the regula-
tions. Also, if a child restraint of the type
specified in the regulations is on the seat, the
occupant classification sensors can detect it
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 passenger air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however, if the occupant does
not sit in the seat properly (for example, by
not sitting upright, by sitting on an edge of
the seat, or by otherwise being out of
position), 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 prop-
erly installed in a rear seat. If this is not
possible, the occupant classification sensors
are designed to operate as described above
to turn the front passenger air bag OFF for
specified child restraints. Failing to properly
secure child restrains and to use the ALR
mode may allow the restraint to tip or move
in an accident or sudden stop. This can also
result in the passenger air bag inflating in a
crash instead of being OFF. (See “Child
restraints” (P.1-31) for proper use and
installation.)
If the front passenger seat is not occupied,
the passenger 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 being de-
tected by the occupant classification sen-
sors. 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 instructions in this manual.
Always be sure that you and all vehicle
occupants are seated and restrained prop-
erly.
Using the front passenger air bag status
light, you can monitor when the front
passenger air bag is automatically turned
OFF with the seat occupied. The light will
not illuminate when the front passenger seat
is unoccupied.
If an adult occupant is in the seat but the
front passenger air bag status light is
illuminated (indicating that the air bag is
OFF), it could be that the person is a small
adult, or is not sitting on the seat properly.
If a child restraint must be used in the front
seat, the front passenger air bag status light
