2018 INFINITI QX30 inflation pressure

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.

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.

WARNING
•The exhaust gas and the exhaust system
are very hot. Keep people, animals and
flammable materials away from the ex-
haust system components.
•Do not stop or park the vehicle over
flammable materials such as dry grass,
wastepaper or rags. They may ignite
and cause a fire.
CAUTION
•Do not use leaded gasoline. (See "Rec-
ommended fluids/lubricants and ca-
pacities".) Deposits from leaded gaso-
line seriously reduce the ability of the
three-way catalyst to help reduce ex-
haust pollutants and/or damage the
three-way catalyst.
•Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems may cause overrich
fuel to flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly. It is rec-ommended 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 recom-
mended 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 monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of yourtires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. 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 driv-
er’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 system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS

Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips.
The recommended tire pressure specifica-
tions are shown on the F.M.V.S.S./
C.M.V.S.S. label or the Tire and Loading In-
formation label (if so equipped) under the
Cold Tire Pressure heading. The Tire and
Loading Information label is affixed to the
driver side center pillar. Tire pressures should
be checked regularly because:
•Most tires naturally lose air over time.
•Tires can lose air suddenly when driven
over potholes or other objects or if the
vehicle strikes a curb while parking.
The tire pressures should be checked when
the tires are cold. The tires are considered
COLD after the vehicle has been parked for
3 or more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.
WARNING
•Improperly inflated tires can fail sud-
denly and cause an accident.
•The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S. S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on the
Tire and Loading Information label (if so
equipped). Do not load your vehicle be-
yond this capacity. Overloading your
vehicle may result in reduced tire life,
unsafe operating conditions due to pre-
mature tire failure, or unfavorable han-
dling characteristics and could also lead
to a serious accident. Loading beyond
the specified capacity may also result in
failure of other vehicle components.
•Before taking a long trip, or whenever
you heavily load your vehicle, use a tire
pressure gauge to ensure that the tire
pressures are at the specified level.
•For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
