2018 INFINITI QX30 sensor

WARNING
•The front-air bags ordinarily will not in-
flate in the event of a side impact, rear
impact, rollover, or lower severity fron-
tal collision. Always wear the seat belts
to help reduce the risk or severity of in-
jury in accidents.
•The front passenger air bag will not
inflate if the OFF>
indicator light is lit. For
additional information, refer to "Front
passenger air bag and status light".
•The seat belts and the front-impact air
bags are most effective when you are
sitting well back and upright in the seat.
The front air bags inflate with great
force. Even with the INFINITI Advanced
Air Bag System, if you are unrestrained,
leaning forward, sitting sideways, or
out of position in any way, you are at
greater risk of injury or death in a crash.
You may also receive serious or fatal in-
juries from the front air bag if you are up
against it when it inflates. Always sit
back against the seatback and as far
away as practical from the steering
wheel. Always properly use the seat
belts.
•The driver and front passenger seat belt
buckles are equipped with sensors that
detect if the seat belts are fastened. The
INFINITI Advanced Air Bag System
monitors the severity of a collision and
seat belt usage then inflates the air bags
as needed. Failure to properly wear seat
belts can increase the risk or severity of
injury in an accident.
•The front passenger seat is equipped
with an occupant classification sensor
(pressure sensor) that turns the front
passenger air bag OFF under some con-
ditions. This sensor is only used in this
seat. Failure to be properly seated and
wearing the seat belt can increase the
risk or severity of injury in an accident.
For additional information, refer to
"Front passenger air bag and status
light".
•Keep hands on the outside of the steer-
ing wheel. Placing them inside the steer-
ing wheel rim could increase the risk that
they are injured when the front air bag
inflates.
WARNING
Never let children ride unrestrained or ex-
tend their hands or face out of the window.
Do not attempt to hold them in your lap or
arms. Some examples of dangerous riding
positions are shown in the illustrations.

WARNING
To ensure proper operation of the passen-
ger's INFINITI Advanced Air Bag System,
please observe the following items:
•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 may deploy in
a collision. For additional information
about installing and using child re-
straints, refer to "Child restraints".
•Confirm the operating condition with
the front passenger air bag status light.
NIC2754
Safety — seats, seat belts and supplemental restraint system1-43

•If you notice that the front passenger
air bag status light is not operating as
described in this section. It is recom-
mended that you visit an INFINITI re-
tailer to check the occupant classifica-
tion system.
•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.
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 warn-
ings 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 supple-
mental 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 frontalcollisions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag
system operation.
The INFINITI Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle sensor and occupant classifica-
tion sensor (pressure sensor). Inflator opera-
tion 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 may be automatically turned off un-
der some conditions, depending on the infor-
mation provided by the Occupation Classifi-
cation System Sensor. If the front passenger
air bag is OFF, the OFF>
indicator light will be illuminated.
For additional information, refer to "Front
passenger air bag and status light". One front
air bag inflating does not indicate improper
performance of the system.
If a crash occurs in which the vehicle's air
bags deploy, by design the vehicle may not
restart. If this occurs, it is recommended that
you visit an INFINITI retailer for repair.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, you
may 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 do not provide 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
1-44Safety — seats, seat belts and supplemental restraint system

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 a few seconds af-
ter the engine starts if the system is opera-
tional.
Front passenger air bag and status
light
WARNING
The front passenger air bag is designed to
automatically turn OFF under some condi-
tions. Read this section carefully 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 con-
cerning the use of seats, seat belts and
child restraints can increase the risk or se-
verity of injury in an accident.

dicator light
Status light
The front passenger seat is equipped with an
occupant classification sensor (pressure sen-
sor) that turns the front passenger air bag on
or off depending on the weight applied to the
front passenger seat. The indicator lights in-
form you whether the front passenger front
air bag is disabled or enabled.
Place the ignition in the ON position. The
system carries out a self-diagnosis.The and SENGER AIRBAG ON> indicator lights will
light up simultaneously for approximately six
seconds.
The indicator lights display the status of the
front passenger front air bag:
• lights up: the
front passenger front air bag is enabled. If,
in the event of an accident, all deployment
criteria are met, the front passenger front
air bag is deployed.
• lights up:
the front passenger front air bag is dis-
abled. It will then not be deployed in the
event of an accident.
If the status of the front passenger front air
bag changes while the vehicle is in motion, an
air bag display message appears in the ve-
hicle information display. When the front
passenger seat is occupied, always pay at-
tention to the
and indicator
lights. Be aware of the status of the front
passenger front air bag both before and dur-
ing the journey.
If neither the
or the indicator
lights light up, or if either indicator light only
lights up intermittently during the journey, the
front passenger seat may not be used for a

child restraint. Use another seating position
for the child restraint. INFINITI recommends
that all child restraints be installed in the rear
seat. Preteen children should be seated in
the rear seat. For further information see
"Troubleshooting" later in this section.
Front passenger air bag
The front passenger air bag is designed 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 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
under some conditions. Certain sensors are
used to meet the requirements.
The occupant classification sensor in this ve-
hicle is a pressure sensor. It is designed to
detect an occupant and objects on the seat
by weight. For example, if a child up to the
approximate size and weight of a one year
old is properly restrained is in the front pas-
senger seat, the INFINITI Advanced Air Bag
System is designed to turn the front passen-
ger air bag OFF. For a properly restrained
child who is larger than the approximate sizeand weight of a one year old, the front pas-
senger air bag may or may not be automati-
cally turned OFF, depending on the size of
the child and the type of child restraint being
used. After installing the child restraint and
positioning the child, place the ignition switch
in the ON position: if the BAG OFF> indicator light is illuminated, the
air bag is OFF. If the ON> indicator light is illuminated, the air bag
will inflate in a crash. 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 oth-
erwise 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 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 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 passenger air bag
inflating in a crash instead of being OFF. For
additional information about proper use and
installation, refer to "Child restraints".
If the front passenger seat is not occupied,
the front 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'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.
If the automatic front passenger air bag de-
activation system detects that:
•The front passenger seat is unoccupied,
the indica-
tor light lights up after the system self-test
and remains lit. This indicates that the
front passenger front air bag is disabled.

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
injury 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 in-
strument panel or by installing addi-
tional 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
personal injury. For example, do not
change the front seats by placing mate-
rial on the seat cushion or by installing
additional trim material, such as seat
covers, on the seat that are not specifi-
cally designed to assure proper air bag
operation. Additionally, 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 (pressure sensor).
•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 seri-
ous personal injury.
•It is recommended that you visit an
INFINITI retailer for work on and around
the front air bag. It is also recommended
that you visit an INFINITI retailer for
installation of electrical equipment. The
Supplemental Restraint System (SRS)
wiring harnesses* should not be modi-
fied 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 facil-
ity. A cracked windshield could affect
the function of the supplemental air bag
system.

The SRS wiring harness connectors are
yellow 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.
Safety — seats, seat belts and supplemental restraint system1-49

If the seat belt warning light flashes, together
with an intermittent warning tone, this means
that the driver or passenger has not fastened
their seat belt, and the speed of the vehicle is
exceeding 15 MPH (25 km/h).

warning light
WARNING
If the supplemental air bag warning light is
on, it could mean that the front air bag,
driver's knee air bag, side air bag, curtain
air bag and/or pretensioner systems will
not operate in an accident. To help avoid
injury to yourself or others, have your ve-
hicle checked by an INFINITI retailer as
soon as possible.
When the ignition switch is in the ON posi-
tion, the Supplemental Restraint System
(SRS) air bag warning light illuminates to in-
dicate that the system is operational. The
light then tuns off within a few seconds after
the engine is started.
If any of the following conditions occur, the
front air bag, front seat-mounted side-
impact air bag, roof-mounted curtain air bag
and pretensioner systems need servicing:
•The supplemental air bag warning light
remains on for longer than a few seconds
once the engine is running.
•The supplemental air bag warning light
flashes intermittently.
•The supplemental air bag warning light
does not come on at all.
It is recommended you visit an INFINITI re-
tailer for these services. Unless checked and
repaired, the supplemental restraint system
(air bag system) and/or the pretensioner sys-
tems may not function properly. For addi-
tional information, refer to "Supplemental
Restraint System (SRS)".
Coolant warning light
WARNING
If the coolant warning light is lit, the engine
may not be being cooled sufficiently and
may be damaged.
Never drive with an overheated engine.
Driving when your engine is overheated can
cause some fluids which may have leaked
into the engine compartment to catch fire.
In addition, steam from an overheated en-
gine can cause serious burns, which can oc-
cur just by opening the hood.
There is a risk of injuryIf the red coolant warning light lights up while
the engine is running and the coolant tem-
perature gauge is at the start of the scale, the
temperature sensor for the coolant tempera-
ture gauge is faulty. The coolant temperature
is no longer being monitored. There is a risk of
engine damage if the coolant temperature is
too high.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions, and switch
off the engine. Do not continue driving under
any circumstances.
Consult an INFINITI retailer.
If the red coolant warning light comes on
while the engine is running, with or without
an accompanying warning tone, it could
mean that:
•The coolant level is too low.
•If the coolant level is correct, the airflow to
the engine radiator may be blocked or the
electric engine radiator fan may be mal-
functioning.
•The coolant is too hot and the engine is no
longer being cooled sufficiently.
Observe the additional display messages in
the vehicle information display.
