tire size INFINITI QX30 2017 Owners Manual

WARNING
•After adjustment, release the adjustment
button and then try to move the shoulder
belt down to make sure that it is securely
fixed in position.
•The shoulder belt anchor height should be
adjusted to the position that is best for you.
Failure to do so may reduce the effective-
ness of the entire restraint system and in-
crease the chance or severity of injury in an
accident.
SEAT BELT EXTENDERS
If, because of body size or driving position, it is
not possible to properly fit the lap/shoulder
belt and fasten it, an extender that is compat-
ible with the installed seat belts is available
that can be purchased. The extender adds
approximately 8 in (200 mm) of length and may
be used for either the driver or front passenger
seating position. It is recommended you visit an
INFINITI retailer for assistance with purchasing
an extender if an extender is required.
WARNING
•Only INFINITI seat belt extenders, made by
the same company which made the original
equipment seat belts, should be used with
the INFINITI seat belts.
•Adults and children who can use the stan-
dard seat belt should not use an extender.
Such unnecessary use could result in seri-
ous personal injury in the event of an acci-
dent.
•Never use seat belt extenders to install
child restraints. If the child restraint is not
secured properly, the child could be seri-
ously injured in a collision or a sudden stop.
SEAT BELT MAINTENANCE
•To clean the seat belt webbing,apply a mild
soap solution or any solution recommended
for cleaning upholstery or carpets. Then wipe
with a cloth and allow the seat belts to dry in
the shade. Do not allow the seat belts to
retract until they are completely dry.
•If dirt builds up in the shoulder belt guideof
the seat belt anchors, the seat belts may
retract slowly. Wipe the shoulder belt guide
with a clean, dry cloth.
•Periodically check to see that the seat belt
and the metal components, such as buckles,
tongues, retractors, flexible wires and an-
chors, work properly. If loose parts, deterio-
ration, cuts or other damage on the webbing
is found, the entire seat belt assembly
should be replaced.

driven at speeds above 16 MPH (25 km/h) to acti-
vate the TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge to check
the tire pressure.
The low tire pressure warning message appears
each time the ignition switch is placed in the ON
position as long as the low tire pressure warn-
ing light remains illuminated.

If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the ignition switch is
placed in the ON position. The light will remain on
after 1 minute. Have the system checked. It is
recommended that you visit an INFINITI retailer
for this service. The low tire pressure warning
does not appear if the low tire pressure warning
light illuminates to indicate a TPMS malfunction.
For additional information, seeTire Pressure
Monitoring System (TPMS)in the5. Starting
and drivingsection.
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.
Starting and driving5-5

•If at all possible, avoid sharp turning ma-
neuvers, particularly at high speeds. Your
INFINITI vehicle has a higher center of grav-
ity than a passenger car. The vehicle is not
designed for cornering at the same speeds
as passenger cars. Failure to operate this
vehicle correctly could result in loss of con-
trol and/or a rollover accident.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted, or
radial), and tread pattern on all four wheels.
Install tire chains on the front wheels when
driving on slippery roads and drive care-
fully.
•Be sure to check the brakes immediately
after driving in mud or water. .
•Avoid parking your vehicle on steep hills. If
you get out of the vehicle and it rolls for-
ward, backward or sideways, you could be
injured.
•Whenever you drive off-road through sand,
mud or water as deep as the wheel hub, more
frequent maintenance may be required. For ad-
ditional information, refer toMaintenance
schedulesin the9. Maintenance and Sched-
ulessection.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS (IF SO
EQUIPPED)
WARNING
•Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Install tire chains on the front wheels when
driving on slippery roads and drive care-
fully.
•This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in.
•For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any D (Drive) or R (Re-
verse) position with the engine running. Do-
ing so may result in drivetrain damage or
unexpected vehicle movement which could
result in serious vehicle damage or personal
injury
•Do not attempt to test an AWD 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 you inform test facil-
ity personnel that your vehicle is equipped
with AWD before it is placed on a dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpected
vehicle movement which could result in se-
rious vehicle damage or personal injury.
•When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
Starting and driving5-13

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

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.

TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, INFINITI recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. It is rec-
ommended that you visit an INFINITI retailer
for the tire type, size, speed rating and
availability information.
2. For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded snow
tires, on wet or dry surfaces, may be poorer than
that of non-studded snow tires.
3. Tire chains may be used if desired. Make
sure they are the proper size for the tires on
your vehicle and are installed according to
the chain manufacturer’s instructions. Use
chain tensioners when recommended by the
tire chain manufacturer to ensure a tight fit.
Loose end links of the tire chains must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fendersor underbody. In addition, drive at a reduced
speed, otherwise, your vehicle may be dam-
aged and/or vehicle handling and perfor-
mance may be adversely affected.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during the winter:
•A scraper and stiff-bristled brush to remove
ice and snow from the windows.
•A sturdy, flat board to be placed under the
jack to give it firm support.
•A shovel to dig the vehicle out of snowdrifts.
•Extra washer fluid to refill the windshield
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
•Wet ice (32°F, 0°C and freezing rain), very
cold snow or ice can be slick and very hard
to drive on. The vehicle will have much less
traction or “grip” under these conditions.
Try to avoid driving on wet ice until the road
is salted or sanded.
•Whatever the condition, drive with caution.
Accelerate and slow down with care. If ac-
celerating or downshifting too fast, the
drive wheels will lose even more traction.
•Allow more stopping distance under these
conditions. Braking should be started
sooner than on dry pavement.
•Allow greater following distances on slip-
pery roads.
•Watch for slippery spots (glare ice). These
may appear on an otherwise clear road in
shaded areas. If a patch of ice is seen ahead,
brake before reaching it. Try not to brake
while on the ice, and avoid any sudden
steering maneuvers.
•Do not use cruise control on slippery roads.
•Snow can trap dangerous exhaust gas under
your vehicle. Keep snow clear of the exhaust
pipe and from around your vehicle.
