2023 INFINITI QX55 child restraint

Booster seat installation
WARNING
To avoid injury to child, do not use the lap/
shoulder belt in the Automatic Locking Re-
tractor (ALR) mode when using a booster
seat with the seat belts.
For additional information, see “Child safety”
(P. 1-19), “Child restraints” (P. 1-21) and
“Booster seats” (P. 1-38) before installing a
child restraint.
Follow these steps to install a booster seat in
the rear seats or in the front passenger seat:
1.If you must install a booster seat in the
front seat, move the seat to the rearmost
position.
2. Position the booster seat on the seat. Only place it in a front-facing direction.
Always follow the booster seat manufac-
turer’s instructions. 3. The booster seat should be positioned on
the 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. 1-52).

WARNING
• Children may be severely injured or killed
when the front air bags, side air bags or
curtain air bags inflate if they are not
properly restrained. Pre-teens and chil-
dren should be properly restrained in the
rear seat, if possible.
• Even with the INFINITI Advanced Air
Bag System, never install a rear-facing
child restraint in the front seat. An in-
flating front air bag could seriously injure
or kill your child. For additional informa-
tion, see “Child restraints” (P. 1-21).WARNING
Front seat-mounted side-impact supple-
mental air bags and roof-mounted curtain
side-impact and rollover supplemental air
bags:
• The side air bags and curtain air bags
ordinarily will not inflate in the event of a
frontal impact, rear impact, or lower se-
verity side collision. Always wear your
seat belts to help reduce the risk or se-
verity of injury in various kinds of
accidents.

WARNING
To ensure proper operation of the passen-
ger’s INFINITI Advanced Air Bag System,
please observe the following items.
• Do not allow a passenger in the rear seat
to push or pull on the seatback pocket.
• Do not place heavy loads heavier than
9.1 lbs. (4 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
• Make sure that there is nothing pressing
against the rear of the seatback, such as
a child restraint installed in the rear seat
or an object stored on the floor.
• Make sure that there is no object placed
under the front passenger seat.
• Make sure that there is no object placed
between the seat cushion and the center
console or between the seat cushion and
the door. •
If a forward-facing child restraint is in-
stalled in the front passenger seat, do
not position the front passenger seat so
the child restraint contacts the instru-
ment panel. If the child restraint does
contact the instrument panel, the sys-
tem may determine the seat is occupied
and the passenger air bag and front pas-
senger supplemental knee air bag may
deploy in a collision. Also the front pas-
senger air bag status light may not illu-
minate. For additional information, see
“Child restraints” (P. 1-21).
• Confirm the operating condition with
the front passenger air bag status light.
• If you notice that the front passenger air
bag status light is not operating as de-
scribed in this section, get the occupant
classification system checked. It is rec-
ommended that you visit an INFINITI re-
tailer for this service.
• Until you have confirmed with a retailer
that your passenger seat occupant clas-
sification system is working properly,
position the occupants in the rear seat-
ing positions. •
Do not position the front passenger seat
so it contacts the rear seat. If the front
seat does contact the rear seat, the air
bag system may determine a sensor mal-
function has occurred and the front pas-
senger air bag status light may illuminate
and the supplemental air bag warning
light may flash.
This vehicle is equipped with the INFINITI
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements un-
der U.S. regulations. It is also permitted in
Canada. All of the information, cautions and
warnings in this manual still apply and must
be followed.
The driver supplemental front-impact air bag
is located in the center of the steering wheel.
The front passenger supplemental front-
impact air bag is mounted in the dashboard
above the glove box. The front air bags are
designed to inflate in higher severity frontal
collisions, although they may inflate if the
forces in another type of collision are similar
to those of a higher severity frontal impact.
They may not inflate in certain frontal colli-
sions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag
system operation.

Front passenger air bag and status light
WARNING
The front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed to automatically turn OFF under
some conditions. Read this section care-
fully to learn how it operates. Proper use of
the seat, seat belt, and child restraints is
necessary for most effective protection.
Failure to follow all instructions in this
manual concerning the use of seats, seat
belts, and child restraints can increase the
risk or severity of injury in an accident.Status light
The front passenger seat is equipped with an
occupant classification sensor (weight sen-
sor) that turns the front passenger air bag
and front passenger supplemental knee air
bag on or off depending on the weight ap-
plied to the front passenger seat. The status
of the front passenger air bag and front pas-
senger supplemental knee air bag (ON or
OFF) is indicated by the front passenger air
bag status light
which is located on the
instrument panel.
After the ignition switch is placed in the "ON"
position, the front passenger air bag status
light on the instrument panel illuminates for
about 7 seconds and then turns off or re-
mains illuminated depending on the front
passenger seat occupied status. The light op-
erates as follows:
CONDITION DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG AND FRONT PASSENGER
SUPPLEMENTAL KNEE AIR BAG STATUS
Empty Empty front passenger seat ON (illuminated) INHIBITED
Nobody/Somebody Bag or Child or Child Restraint or
Small Adult in front passenger seat ON (illuminated)
INHIBITED
Adult Adult in the front passenger seat OFF (dark) ACTIVATED
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, see “Normal op-
eration” (P. 1-54) and “Troubleshooting”
(P. 1-55).
LRS0865
1-52Safety-Seats, seat belts and supplemental restraint system

Front passenger air bag
The front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed to automatically turn OFF when the
vehicle is operated under some conditions as
described below in accordance with U.S.
regulations. If the front passenger air bag and
front passenger supplemental knee air bag
are OFF, they will not inflate in a crash. The
driver air bag and other air bags in your ve-
hicle 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 and front passenger
supplemental knee air bag to be automati-
cally turned OFF. For small adults it may be
turned OFF, however, if the occupant takes
his/her weight off the seat cushion (for ex-
ample, 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 bags 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 front passenger
supplemental knee air bag OFF for specified
child restraints as required by the regulations.
Failing to properly 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 front passenger supplemental knee
air bag inflating in a crash instead of beingOFF. For additional information, see “Child
restraints” (P. 1-21).
If the front passenger seat is not occupied,
the front passenger air bag and front passen-
ger supplemental 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 de-
tected by the occupant 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, con-
trary to the instructions in this manual. Al-
ways be sure that you and all vehicle occu-
pants are seated and restrained properly.
Using the front passenger air bag status light,
you can monitor when the front passenger air
bag and front passenger supplemental knee
air bag is automatically 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 front passenger supplemental knee
air bag is OFF), it could be that the person is a
small adult, or is not sitting on the seat prop-
erly 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
Safety-Seats, seat belts and supplemental restraint system1-53

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
passenger air bag and front passenger
supplemental knee air bag might inflate in a
crash), it could be that the child restraint or
seat belt is not being used properly. Make
sure that the child restraint is installed prop-
erly, the seat belt is used properly and the
occupant is positioned properly. If the air bag
status light is still not illuminated, reposition
the occupant or child restraint in a rear seat.
If the front passenger air bag status light will
not illuminate even though you believe that
the child restraint, the seat belts and the oc-
cupant are properly positioned, it is recom-
mended that you take your vehicle to an
INFINITI retailer. An INFINITI retailer can
check system status by using a special tool.
However, until you have confirmed with a
retailer that your air bag is working properly,
reposition the occupant or child restraint in a
rear seat.
The INFINITI Advanced Air Bag System and
front passenger air bag status light will take a
few seconds to register a change in the front
passenger seat status. This is normal system
operation and does not indicate a
malfunction.If a malfunction occurs in the front passenger
air bag system, the supplemental air bag
warning light
, located in the meter and
gauges area of the instrument panel, will be
illuminated (blinking or steadily lit). Have the
system checked. It is recommended that you
visit an INFINITI retailer for this service.
Normal operation
In order for the occupant classification sen-
sor system to classify the front passenger
based on weight, please follow the precau-
tions and steps outlined below:
Precautions
• Make sure that there are no objects weigh- ing over 9.1 lbs. (4 kg) hanging on the seat
or placed in the seatback pocket.
• Make sure that a child restraint or other object is not pressing against the rear of the
seatback.
• Make sure that a rear passenger is not pushing or pulling on the back of the front
passenger seat.
• Make sure that the front passenger seat or seatback is not forced back against an ob-
ject on the seat or floor behind it.
• Make sure that there is no object placed under the front passenger seat. Steps
1. Adjust the seat as outlined in the “Seats”
(P. 1-2) section of this manual. Sit upright,
leaning against the seatback, and cen-
tered on the seat cushion with your feet
comfortably extended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seat belts” (P. 1-11) section of this
manual. Front passenger seat belt buckle
status is monitored by the occupant clas-
sification system, and is used as an input
to determine occupancy status. So, it is
highly recommended that the front pas-
senger fasten their seat belt.
4. Remain in this position for 30 seconds allowing the system to classify the front
passenger before the vehicle is put into
motion.
5. Ensure proper classification by checking the front passenger air bag status light.
