INFINITI QX55 2023 Manual PDF

The INFINITI Advanced Air Bag System
monitors information from the crash zone
sensor, door sensors, satellite sensors, the Air
bag Control Unit (ACU), seat belt buckle sen-
sor and occupant classification sensor
(weight sensor). Inflator operation is based
on the severity of a collision and seat belt
usage for the driver. For the front passenger,
the occupant classification sensor is also
monitored. Based on information from the
sensor, only one front air bag may inflate in a
crash, depending on the crash severity and
whether the front occupants are belted or
unbelted. Additionally, the front passenger
air bag and front passenger supplemental
knee air bag may be automatically turned off
under some conditions, depending on the
weight detected on the passenger seat and
how the seat belt is used. If the front passen-
ger air bag and front passenger supplemental
knee air bag are OFF, the front passenger air
bag status light will be illuminated. For addi-
tional information, see “Front passenger air
bag and status light” (P. 1-52). One front air
bag inflating does not indicate improper per-
formance of the system.
If you have any questions about your air bag
system, it is recommended that you visit an
INFINITI retailer to obtain information about
the system. If you are considering modifica-
tion of your vehicle due to a disability, youmay also contact INFINITI. Contact informa-
tion is contained in the front of this Owner's
Manual.
When a front air bag inflates, a fairly loud
noise may be heard, followed by the release
of smoke. This smoke is not harmful and does
not indicate a fire. Care should be taken to
not inhale it, as it may cause irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.
Front air bags, along with the use of seat
belts, help to cushion the impact force on the
face and chest of the front occupants. They
can help save lives and reduce serious injuries.
However, an inflating front air bag may cause
facial abrasions or other injuries. Front air
bags, other than the driver and front passen-
ger supplemental knee air bags, do not pro-
vide restraint to the lower body.
Even with INFINITI Advanced Air Bags, seat
belts should be correctly worn and the driver
and passenger seated upright as far as prac-
tical away from the steering wheel or instru-
ment panel. The front air bags inflate quickly
in order to help protect the front occupants.
Because of this, the force of the front air bag
inflating can increase the risk of injury if the
occupant is too close to, or is against, the
front air bag module during inflation.
The front air bags deflate quickly after a
collision.
The front air bags operate only when the
ignition switch is placed in the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.

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.
1-54Safety-Seats, seat belts and supplemental restraint system

NOTE:
This vehicle’s occupant classification sensor
system generally keeps the classification
locked during driving, so it is important that
you confirm that the front passenger is
properly classified prior to driving. However,
the occupant classification sensor may re-
calculate the weight of the occupant under
some conditions (both while driving and
when stopped), so front passenger seat oc-
cupants should continue to remain seated as
outlined above.
Troubleshooting
If you think the front passenger air bag status
light is incorrect:
1. If the light is ON with an adult occupyingthe front passenger seat:
• Occupant is a small adult — the air bag light is functioning as intended. The front pas-
senger air bag and front passenger supple-
mental knee air bag are suppressed.
However, if the occupant is not a small adult,
then this may be due to the following condi-
tions that may be interfering with the weight
sensors: • Occupant is not sitting upright, leaning
against the seatback, and centered on the
seat cushion with his/her feet comfortably
extended to the floor.
• A child restraint or other object pressing against the rear of the seatback.
• A rear passenger pushing or pulling on the back of the front passenger seat.
• Forcing the front seat or seatback against an object on the seat or floor behind it.
• An object placed under the front passenger seat.
• An object placed between the seat cushion and center console or between the seat
cushion and the door.
If the vehicle is moving, please come to a stop
when it is safe to do so. Check and correct
any of the above conditions. Restart the ve-
hicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially. If the light is still ON after this, the person
should be advised not to ride in the front
passenger seat and the vehicle should be
checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.
2. If the light is OFF with a small adult, child
or child restraint occupying the front pas-
senger seat.
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
• Small adult or child is not sitting upright, leaning against the seatback, and centered
on the seat cushion with his/her feet com-
fortably extended to the floor.
• The child restraint is not properly installed, as outlined in the “Child Restraints”
(P. 1-21) section of this manual.
• An object weighing over 9.1 lbs. (4 kg) hanging on the seat or placed in the seat-
back pocket.
• A child restraint or other object pressing against the rear of the seatback.
• A rear passenger pushing or pulling on the back of the front passenger seat.
• Forcing the front seat or seatback against an object on the seat or floor behind it.
Safety-Seats, seat belts and supplemental restraint system1-55

• An object placed under the front passengerseat.
• An object placed between the seat cushion and center console.
If the vehicle is moving, please come to a stop
when it is safe to do so. Check and correct
any of the above conditions. Restart the ve-
hicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still OFF after this, the small
adult, child or child restraint should be repo-
sitioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit an INFINITI re-
tailer for this service.
3. If the light is OFF with no front passenger and no objects on the front passenger
seat, the vehicle should be checked. It is
recommended that you visit an INFINITI
retailer as soon as possible.
Other supplemental front-impact air bag
precautions
WARNING
• Do not place any objects on the steering
wheel pad or on the instrument panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may be-
come dangerous projectiles and cause in-
jury if the front air bags inflate.
• Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
• No unauthorized changes should be
made to any components or wiring of the
supplemental air bag system. This is to
prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system.
• Do not make unauthorized changes to
your vehicle's electrical system, suspen-
sion system or front end structure. This
could affect proper operation of the
front air bag system. •
Tampering with the front air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument panel
assembly by placing material over the
steering wheel pad and above the instru-
ment panel or by installing additional
trim material around the air bag system.
• Removing or modifying the front pas-
senger seat may affect the function of
the air bag system and result in serious
personal injury.
• Modifying or tampering with the front
passenger seat may result in serious per-
sonal injury. For example, do not change
the front seats by placing material on the
seat cushion or by installing additional
trim material, such as seat covers, on the
seat that are not specifically designed to
assure proper air bag operation. Addi-
tionally, do not stow any objects under
the front passenger seat or the seat
cushion and seatback. Such objects may
interfere with the proper operation of
the occupant classification sensor
(weight sensor).
1-56Safety-Seats, seat belts and supplemental restraint system

•No unauthorized changes should be
made to any components or wiring of the
seat belt system. This may affect the
front air bag system. Tampering with the
seat belt system may result in serious
personal injury.
• It is recommended that you visit an
INFINITI retailer for work on and around
the front air bags. It is also recommended
that you visit an INFINITI retailer for in-
stallation of electrical equipment. The
Supplemental Restraint System (SRS)
wiring harnesses* should not be modified
or disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the air bag system.
• A cracked windshield should be replaced
immediately by a qualified repair facility.
A cracked windshield could affect the
function of the supplemental air bag
system.
*The SRS wiring harness connectors are yel-
low and orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the front air bag
system and guide the buyer to the appropri-
ate sections in this Owner's Manual.
Front and rear outboard
seat-mounted side-impact
supplemental air bag and
roof-mounted curtain side-impact
and rollover supplemental air bag
systems
The side air bags are located in the outside of
the seatback of the front and rear outboard
seats. The curtain air bags are located in the
side roof rails. All of the information, cau-
tions and warnings in this manual must be
followed. The side air bags and curtain air
bags are designed to inflate in higher severity
side collisions, although they may inflate if the forces in another type of collision are
similar to those of a higher severity impact.
They are designed to inflate on the side
where the vehicle is impacted. They may not
inflate in certain side collisions.
Curtain air bags are also designed to inflate in
certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments (for example, during severe off-
roading) may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not always an
indication of proper side air bag and curtain
air bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard, fol-
lowed by the release of smoke. This smoke is
not harmful and does not indicate a fire. Care
should be taken not to inhale it, as it may
cause irritation and choking. Those with a
history of a breathing condition should get
fresh air promptly.
Side air bags, along with the use of seat belts,
help to cushion the impact force on the chest
and pelvic area of the front and rear outboard
occupants. Curtain air bags help to cushion
the impact force to the head of occupants in
the front and rear outboard seating positions.
They can help save lives and reduce serious
LRS3142
Safety-Seats, seat belts and supplemental restraint system1-57

injuries. However, an inflating side air bag
and curtain air bag may cause abrasions or
other injuries. Side air bags and curtain air
bags do not provide restraint to the lower
body.
The seat belts should be correctly worn and
the driver, front passenger and rear outboard
occupants seated upright as far as practical
away from the side air bag. Rear seat passen-
gers should be seated as far away as practi-
cal from the door finishers and side roof rails.
The side air bags and curtain air bags inflate
quickly in order to help protect the occupants.
Because of this, the force of the side air bag
and curtain air bag inflating can increase the
risk of injury if the occupant is too close to, or
is against, these air bag modules during infla-
tion. The side air bag will deflate quickly after
the collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain air bags oper-
ate only when the ignition switch is placed in
the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.WARNING
• Do not place any objects near the seat-
back of the front and rear seats. Also, do
not place any objects (an umbrella, bag,
etc.) between the front and rear door
finisher and the front and rear seat. Such
objects may become dangerous projec-
tiles and cause injury if a side air bag
inflate.
• Right after inflation, several side air bag
and curtain air bag system components
will be hot. Do not touch them; you may
severely burn yourself.
• No unauthorized changes should be
made to any components or wiring of the
side air bag and curtain air bag systems.
This is to prevent damage to or acciden-
tal inflation of the side air bag and cur-
tain air bag or damage to the side air bag
and curtain air bag systems.
• Do not make unauthorized changes to
your vehicle's electrical system, suspen-
sion system or side panel. This could af-
fect proper operation of the side air bag
and curtain air bag systems. •
Tampering with the side air bag system
may result in serious personal injury. For
example, do not change the front and
rear seats by placing material near the
seatbacks or by installing additional trim
material, such as seat covers, around the
side air bag.
• It is recommended that you visit a
INFINITI retailer for work on and around
the side air bag and curtain air bag. It is
also recommended that you visit a
INFINITI retailer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical test
equipment and probing devices should
not be used on the side air bag or curtain
air bag system.
* The SRS wiring harness connectors are yel-
low and orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the side air bag
and curtain air bag systems and guide the

Driver and front passenger
supplemental knee air bagThe knee air bag is located in the knee bolster,
on the driver’s and passenger’s side.All of the
information, cautions and warnings in this
manual apply and must be followed. The
knee air bag is designed to inflate in higher
severity frontal collisions, although it may in-
flate if the forces in another type of collision
are similar to those of a higher severity fron-
tal impact. It may not inflate in certain
collisions.
Vehicle damage (or lack of it) is not always an
indication of proper knee air bag operation. When the knee air bag inflates, a fairly loud
noise may be heard, followed by release of
smoke. This smoke is not harmful and does
not indicate a fire. Care should be taken not
to inhale it, as it may cause irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.
The knee air bag helps to cushion the impact
force on the knees of the driver and passen-
ger. It can help reduce serious injuries. How-
ever, an inflating knee air bag may cause
abrasions or other injuries. The knee air bag
provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of this,
the force of the knee air bag inflating can
increase the risk of injury if the occupant is
too close to, or is against, this air bag module
during inflation. The knee air bag will deflate
quickly after the collision is over OR the knee
air bag will remain inflated for a short time.
The knee air bag operates only when the ig-
nition switch is placed in the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.
