2018 INFINITI QX30 inflation pressure

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 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.

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.

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. 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 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 system1-51

•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" in the "9. Maintenance and
Schedules" section.) Deposits from
leaded gasoline seriously reduce the
ability of the three-way catalyst to help
reduce exhaust pollutants and/or dam-
age 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 your
tires 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
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from working
properly. Always check the TPMS telltale af-
ter 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.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the
low tire pressure warning light is lit, one or
more of the tires is significantly under-
inflated.
The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h).
Also, this system may not detect a sudden
drop in tire pressure (for example a flat tire
while driving).
For additional information, refer to "Tire
Pressure Monitoring System (TPMS)" in the
"5. Starting and driving" section.
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 thedriver 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 In-
formation” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.

TIRE INFLATION PRESSURE
Checking tire pressure
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge squarely ontothe valve stem. Do not press too hard or
force the valve stem sideways, or air will
escape. If the hissing sound of air escap-
ing from the tire is heard while checking
the pressure, reposition the gauge to
eliminate this leakage.
3. Remove the gauge.
4. Read the tire pressure on the gauge stem and compare it to the specification shown
on the Tire and Loading Information label. 5. Add air to the tire as needed. If too much
air is added, press the core of the valve
stem briefly with the tip of the gauge stem
to release pressure. Recheck the pressure
and add or release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, in- cluding the spare.

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the side-
wall of all tires. This information identifies
and describes the fundamental characteris-
tics of the tire and also provides the tire iden-
tification number (TIN) for safety standard
certification. The TIN can be used to identify
the tire in case of a recall.
