2017 INFINITI QX30 tire pressure

6.Avoid Idling
•Shutting off your engine when safe for
stops exceeding 30 seconds saves fuel
and reduces emissions.
7.Buy an Automated Pass for Toll Roads
•Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
8.Winter Warm Up
•Limit idling time to minimize impact to
fuel economy.
•Vehicles typically need no more than 30
seconds of idling at start-up to effectively
circulate the engine oil before driving.
•Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling.
9.Keeping your Vehicle Cool
•Park your vehicle in a covered parking
area or in the shade whenever possible.
•When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system.
•Keep your engine tuned up.
•Follow the recommended scheduled mainte-
nance.
•Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
•Keep all the wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
•Use the recommended viscosity engine oil.

mended fluids/lubricants and capacitiesin
the10. Technical informationsection
WARNING
•Do not drive beyond the performance capa-
bility of the tires, even with 4WD engaged.
Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause loss
of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in.
•For 4WD equipped vehicles, do not attempt to
raise two wheels off the ground and shift the
transmission to any drive or reverse position
with the engine running. Doing so may result
in drivetrain damage or unexpected vehicle
movement which could result in serious ve-
hicle damage or personal injury.
•Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
even if the other two wheels are raised off
the ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with 4WD before it is placed on a

CAUTION
•If wheels or tires other than INFINITI recom-
mended ones are used, the power steering
system may not operate properly and the
[Power Steering Malfunction See Operators
Manual] warning may appear in the vehicle
information display.
•Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the power steering system may not
operate properly and the [Power Steering
Malfunction See Operators Manual] warn-
ing may appear in the vehicle information
display.
•Do not modify the vehicle’s steering. If
steering parts are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, the power steering system
may not operate properly and the [Power
Steering Malfunction See Operators
Manual] warning may appear in the vehicle
information display.
•Do not place the ignition switch in the on
position while the steering wheel or a tire is
removed.
•Do not turn the steering wheel as much as
possible while the ignition switch is in any
position other than the ON position.
•Installing an accessory on the steering
wheel, or changing the steering wheel, may
reduce the steering performance.
NOTE
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assistance for the steering
wheel will be reduced. This is to prevent over-
heating of the electric power steering system
and protect it from becoming damaged. While
the power assistance is reduced, steering wheel
operation will become heavy. When the tem-
perature of the electric power steering system
decreases, the power assistance level will return
to normal. Avoid repeating such steering wheel
operations that could cause the electric power
steering system to overheat.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking ability at two wheels.
BRAKE PRECAUTIONS
WARNING
While driving on a slippery surface, be careful
when braking, accelerating or downshifting.
Abrupt braking or accelerating could cause the
wheels to skid and result in an accident.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. How-
ever, greater foot pressure on the brake pedal
will be required to stop the vehicle. The stop-
ping distance will be longer.
WARNING
•If the engine is not running or is turned off
while driving, the power assist for the
brakes will not work. Braking will be harder.
•Do not coast with the engine stopped.
BRAKE SYSTEM
Starting and driving5-87

Tire type and condition may also affect braking
effectiveness.
–When replacing tires, install the specified
size of tires on all four wheels.
–
When installing a replacement tire, make sure
that it is the proper size and type as specified on
the tire and loading information label. (See
Wheels and Tiresin the9. Maintenance and
Schedulessection.)
–For detailed information, seeWheels and
tiresin the8. Do-it-yourselfsection.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle at a low speed in
forward or reverse. When the self-test occurs,
you may hear a “clunk” noise and/or feel a
pulsation in the brake pedal. This is normal and
does not indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.

NOTE
Activate VDC as soon as the situations described
above no longer apply. VDC will otherwise not be
able to stabilize the vehicle if the vehicle starts
to skid or a wheel starts to spin.
You can activate/deactivate VDC using the ve-
hicle information display. To activate/
deactivate VDC:
1. Start the engine
2. Press the
orbutton on the
steering wheel to select the [DriveAssist]
menu in the vehicle information display.
3. Press the
orbutton to select
VDC.
4. Press thebutton on the steering
wheel. The current selection is displayed.
5. To activate/deactivate: press thebut-
ton again.
VDC is deactivated if the
warning light
in the combination meter lights up continu-
ously when the engine is running.
Characteristics when VDC is deactivated
:
If VDC is deactivated and one or more wheels
start to spin, theVDC warning lamp
flashes in the combination meter. In such situ-
ations, VDC will not stabilize the vehicle.If you deactivate VDC:
•VDC no longer intervenes in understeer or
oversteer situations.
•Engine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a
cutting action, so the tires cut through the
loose surface until the hit solid ground,
giving better traction.
•Traction control is still activated.
•VDC still provides support when you brake.
EBD (ELECTRONIC BRAKE FORCE
DISTRIBUTION)
EBD monitors and controls the brake pressure
on the rear wheels to help improve handling
during braking.
WARNING
If EBD is malfunctioning, the EBD [Inoperative
See Operator’s Manual] warning is displayed
in the vehicle information display. The
VDC warning lamp may also light up.
If EBD is malfunctioning as a result of a VDC
malfunction, the rear wheels can lock, e.g. un-
der full braking. This increases the risk of skid-
ding and an accident.You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked. It is recommended
you see an INFINITI retailer.
STEER CONTROL
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilisa-
tion.
This steering support is provided in particular if:
•Both right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
•The vehicle starts to skid.
WARNING
No steering support is provided from STEER
CONTROL, if:
•VDC is malfunctioning.
•The steering is faulty.
Power steering will, however, continue to
function.

The hazard warning flasher is used to warn
other drivers when you have to stop or park
under emergency conditions.
When the hazard warning flasher switch is
pushed, all turn signal lights will flash. To turn
off the hazard warning flasher, push the hazard
warning switch again.
WARNING
•If stopping for an emergency, be sure to
move the vehicle well off the road.
•Do not use the hazard warning flashers
while moving on the highway unless un-
usual circumstances force you to drive so
slowly that your vehicle might become a
hazard to other traffic.
•Turn signals do not work when the hazard
warning flasher lights are on.
Some jurisdictions may prohibit the use of the
hazard warning flasher switch while driving.If you have a flat tire, follow the instructions in
this section.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
WARNING
•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.
NIC2621
HAZARD WARNING FLASHER SWITCH FLAT TIRE
6-2In case of emergency

•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not func-
tion and the low tire pressure warning light
will flash for approximately 1 minute. The
light will remain on after 1 minute. It is rec-
ommended you Contact an INFINITI retailer
as soon as possible for tire replacement
and/or system resetting.
•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. It is recommended you visit
an INFINITI retailer for this service.
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the low
tire pressure warning light is lit, and a tire
pressure-related warning (if equipped) appears
in the vehicle information display, one or more
of your tires is significantly under-inflated. If
the vehicle is being driven with low tire pres-
sure, the TPMS will activate and warn you of it
by the low tire pressure warning light (in the
meter panel). This system will activate only
when the vehicle is driven at speeds above 16MPH (25 km/h).
For more details about the TPMS, seeTire
Pressure Monitoring System (TPMS)in the5.

RUN-FLAT TIRES
With special run-flat tires, you can continue to
drive your vehicle even if there is a total loss of
pressure in one or more tires. The affected tire
must not show any clearly visible damage.
You can recognise run-flat tires by the marking
which appears on the tire side wall. You will
find this marking next to the tire size designa-
tion, the load-bearing capacity and the speed
index.Run-flat tires may only be used in conjunction
with an activated tire pressure loss warning
system or tire pressure monitor.
Pressure loss warning message
If a pressure loss warning message appears in
the vehicle information display:
•Observe the instructions in the display
messages.
•Check the tire for damage.
•If driving on, observe the following notes.
The driving distance possible in run-flat mode is
approximately 50 miles (80 km) when the ve-
hicle is partially laden and approximately 20
miles (30 km) when the vehicle is fully laden.
In addition to the vehicle load, the driving
distance possible depends upon:
•Vehicle speed.
•Road condition.
•Outside temperature.
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions/
maneuvers, or it can be increased through a
moderate style of driving.NIC2686
