2017 INFINITI QX30 inflation pressure

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.

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.

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 toTire Pressure
Monitoring System (TPMS)in the5. Starting and
drivingsection.
Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips.
The recommended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S. label or
the Tire and Loading Information label (if so
equipped) under the Cold Tire Pressure head-
ing. The Tire and Loading Information label is
affixed to the driver side center pillar. Tire
pressures should be checked regularly be-
cause:
•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 suddenly
and cause an accident.
•The Gross Vehicle Weight rating (GVWR) is
located on the F.M.V.S. S./C.M.V.S.S. certi-
fication label. The vehicle weight capacity is
indicated on the Tire and Loading Informa-
tion label (if so equipped). Do not load your
vehicle beyond this capacity. Overloading
your vehicle may result in reduced tire life,
unsafe operating conditions due to prema-
ture tire failure, or unfavorable handling
characteristics and could also lead to a se-
rious accident. Loading beyond the speci-
fied 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 pres-
sure 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 Information” (Canada)
in the Warranty Information Booklet.

TIRE INFLATION PRESSURE
Checking tire pressure
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge squarely onto the
valve stem. Do not press too hard or force
the valve stem sideways, or air will escape. If
the hissing sound of air escaping from the
tire is heard while checking the pressure,
reposition the gauge to eliminate this leak-
age.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, includ-
ing the spare.
