pressure sensor INFINITI QX30 2017 Owners Manual

WARNING
•The front-air bags ordinarily will not inflate
in the event of a side impact, rear impact,
rollover, or lower severity frontal collision.
Always wear the seat belts to help reduce
the risk or severity of injury in accidents.
•The front passenger air bag will not inflate if
the passenger air bag status light is lit or if
the front passenger seat is unoccupied. For
additional information, refer toFront pas-
senger air bag and status lightin the1.
Safety — seats, seat belts and supplemen-
tal restraint systemSafety — seats, seat
belts and supplemental restraint system
section.
•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 side-
ways, 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 inju-
ries from the front air bag if you are up
against it when it inflates. Always sit back
against the seatback and as far away aspractical from the steering wheel. Always
properly use the seat belts.
•The driver and front passenger seat belt
buckles are equipped with sensors that de-
tect if the seat belts are fastened. The
INFINITI Advanced Air Bag System monitors
the severity of a collision and seat belt us-
age then inflates the air bags as needed.
Failure to properly wear seat belts can in-
crease 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 conditions. This sensor
is only used in this seat. Failure to be prop-
erly seated and wearing the seat belt can
increase the risk or severity of injury in an
accident. For additional information, refer
toFront passenger air bag and status light
in the1. Safety — seats, seat belts and
supplemental restraint systemsection.
•Keep hands on the outside of the steering
wheel. Placing them inside the steering
wheel rim could increase the risk that they
are injured when the front air bag inflates.
WARNING
Never let children ride unrestrained or extend
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 passenger’s
INFINITI Advanced Air Bag System, please ob-
serve 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 instrument
panel. If the child restraint does contact the
instrument panel, the system may deter-
mine the seat is occupied and the passen-
ger air bag may deploy in a collision. For
additional information about installing and
using child restraints, refer toChild
restraintsin the1. Safety — seats, seat
belts and supplemental restraint system
section.
•Confirm the operating condition with the
front passenger air bag status light.
NIC2754
Safety — seats, seat belts and supplemental restraint system1-45

•If you notice that the front passenger air
bag status light is not operating as de-
scribed in this section. It is recommended
that you visit an INFINITI retailer to check
the occupant classification system.
•Until you have confirmed with a retailer that
your passenger seat occupant classification
system is working properly, position the oc-
cupants in the rear seating positions.
This vehicle is equipped with the INFINITI Ad-
vanced Air Bag System for the driver and front
passenger seats. This system is designed to
meet certification requirements under 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, al-
though 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 collisions. 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 classification sensor (pressure
sensor). Inflator operation is based on the
severity of a collision and seat belt usage for
the driver. For the front passenger, the occu-
pant 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 automati-
cally turned off under some conditions, depend-
ing on the weight detected on the passenger
seat and how the seat belt is used. If the front
passenger air bag is OFF, the front passenger
air bag status light will be illuminated (if the
seat is unoccupied, the light will not be illumi-
nated, but the air bag will be off). For additional
information, refer toFront passenger air bag
and status lightin the1. Safety — seats, seat
belts and supplemental restraint systemsec-
tion. One front air bag inflating does not indi-
cate 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 modification of
your vehicle due to a disability, you may also
contact INFINITI. Contact information is con-
tained 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 abra-
sions 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 practical
away from the steering wheel or instrument
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
1-46Safety — seats, seat belts and supplemental restraint system

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 vehicle
information display (seeSupplemental Re-
straint System (SRS) air bag warning light
earlier in this section). When the front passen-
ger seat is occupied, always pay attention to
the and AIRBAG OFF> indicator lamps. Be aware of the
status of the front-passenger front air bag both
before and during the journey.
If the indicator lamp
remains off and/or the ON> indicator lamp lights up, do not install a
rearward-facing child restraint system on the
front-passenger seat. For further information
seeTroubleshootinglater 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 seatoccupants, such as children, by requiring the
air bag to be automatically turned OFF. 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 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
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 supple-
mental air bag. INFINITI recommends that pre-
teens and children be properly restrained in a
rear seat. INFINITI also recommends that appro-
priate child restraints and booster seats beproperly 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 toChild restraintsin the1. Safety —
seats, seat belts and supplemental restraint
systemsection.
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, contrary
to the instructions in this manual. Always be
sure that you and all vehicle occupants are
seated and restrained properly.

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 occu-
pant and the steering wheel or instrument
panel. Such objects may become 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 severely burn your-
self.
•No unauthorized changes should be made
to any components or wiring of the supple-
mental 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, suspension sys-
tem 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. Tam-
pering includes changes to the steering
wheel and the instrument panel assembly
by placing material over the steering wheel
pad and above the instrument panel or by
installing additional trim material around
the air bag system.
•Removing or modifying the front passenger
seat may affect the function of the air bag
system and result in serious personal in-
jury.
•Modifying or tampering with the front pas-
senger seat may result in serious personal
injury. For example, do not change the front
seats by placing material on the seat cush-
ion or by installing additional trim material,
such as seat covers, on the seat that are not
specifically 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 ob-
jects may interfere with the proper opera-
tion 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 sys-
tem may result in serious 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 electri-
cal equipment. The Supplemental Restraint
System (SRS) wiring harnesses* should not
be modified or disconnected. Unauthorized
electrical test equipment and probing de-
vices 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 func-
tion 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 appropriate sections
in this Owner’s Manual.

WARNING
•Radio waves could adversely affect electric
medical equipment. Those who use a pace-
maker should contact the electric medical
equipment manufacturer for the possible in-
fluences before use.
•If the light does not illuminate with the
ignition switch pushed ON, have the vehicle
checked. It is recommended you visit an
INFINITI retailer for this service.
•If the light illuminates while driving, avoid
sudden steering maneuvers or abrupt brak-
ing, reduce vehicle speed, pull off the road
to a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage the
tires and increase the likelihood of tire fail-
ure. Serious vehicle damage could occur
and may lead to an accident and could result
in serious personal injury or death. Check
the tire pressure for all four tires. Adjust the
tire pressure to the recommended COLD tire
pressure shown on the tire placard, located
in the driver’s door opening, to turn the low
tire pressure warning light off. If the light
still illuminates while driving after adjust-
ing the tire pressure, a tire may be flat. If you
have a flat tire, replace it with a replacement
tire as soon as possible.
•If a replacement tire is mounted or a wheel
is replaced without a TPMS sensor tire pres-
sure will not be indicated, the TPMS will not
function and the low tire pressure warning
light will flash for approximately 1 minute.
The light will remain on after 1 minute. Have
your vehicle’s tires replaced and/or TPMS
system reset as soon as possible. It is rec-
ommended you visit an INFINITI retailer for
these services.
•Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
CAUTION
•The TPMS is not a substitute for the regular
tire pressure check. Be sure to check the tire
pressure regularly.
•If the vehicle is being driven at speeds of
less than 16 MPH (25 km/h), the TPMS may
not operate correctly.
•Be sure to install the specified size of tires
to all four wheels correctly.

CAUTION
•Do not use leaded gasoline. (SeeRecom-
mended fluids/lubricants and capacitiesin
the9. Maintenance and Schedulessec-
tion.) Deposits from leaded gasoline seri-
ously reduce the ability of the three-way
catalyst to help reduce exhaust pollutants
and/or damage the three-way catalyst.
•Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems may cause overrich fuel to flow into
the three-way catalyst, causing it to over-
heat. Do not keep driving if the engine mis-
fires, or if noticeable loss of performance or
other unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended you visit an
INFINITI retailer for this service.
•Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-way
catalyst.
•Do not race the engine while warming it up.
•Do not push or tow your vehicle to start the
engine.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
Each tire, including the spare (if present),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS malfunc-
tion indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from working properly. Always check
the TPMS telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
The vehicle’s wheels have sensors fitted that
monitor the tire pressures in all four tires The
tire pressure monitor warns you if the pressure
drops in one or more of the tires The tire
pressure monitor only functions if the corre-
sponding sensors are fitted to all wheels.
Information on tire pressures is shown in the
vehicle information display. After a few minutes
of driving, the current tire pressure of each tire
is shown in the [Serv.] menu of the vehicle
information display.

WARNING
•Radio waves could adversely affect electri-
cal medical equipment. Those who use a
pacemake should contact their electrical
medical equipment manufacturer for the
pssible influences before use.
•If the low tire pressure warning light illumi-
nates or a tire pressure-related warning is
displayed by the vehicle information dis-
play while driving, avoid sudden steering
maneuvers or abrupt braking, reduce ve-
hicle speed, pull off the road to a safe loca-
tion and stop the vehicle as soon as pos-
sible. Driving with under-inflated tires may
permanently damage the tires and increase
the likelihood of tire failure. Serious vehicle
damage could occur and may lead to an ac-cident and could result in serious personal
injury. Check the tire pressure for all four
tires. Adjust the tire pressure to the recom-
mended COLD tire pressure shown on the
tire and loading information label to turn
the low tire pressure warning light OFF. If
you have a flat tire, replace it with a replace-
ment tire as soon as possible.
•If a replacement wheel is fitted without an
INFINITI TPMS Sensor, the TPMS will not
function and the low tire pressure warning
light will flash for approximately 1 minute.
The light will remain on after 1 minute. It is
recommended you contact an INFINITI re-
tailer as soon as possible for tire replace-
ment and/or system resetting.
•For models with run-flat tires, although you
can continue driving with a punctured run-flat
tire, remember that vehicle handling stability
is reduced, which could lead to an accident
and personal injury. Also, driving a long dis-
tance at high speeds may damage the tires.
–Do not drive at speeds above 50 MPH (80
km/h) and do not drive more than approxi-
mately 93 miles (150 km) with a punctured
run-flat tire. The actual distance the ve-
hicle can be driven on a flat tire depends
on outside temperature, vehicle load, road
conditions and other factors.
–If you detect any unusual sounds or
vibrations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously dam-
aged and need to be replaced.
•Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
•If you used Emergency Tire Sealant to repair
a minor tire puncture, the TPMS sensor
should be checked when repairing or re-
placing the tire (for models equipped with
the emergency tire puncture repair kit). It is
recommended you visit an INFINITI retailer
for this service.
•INFINITI recommends using only INFINITI
Genuine Emergency Tire Sealant provided
with your vehicle. Other tire sealants may
damage the valve stem seal which can
cause the tire to lose air pressure (for mod-
els equipped with the emergency tire punc-
ture repair kit).
