2018 INFINITI QX30 run flat

low tire pressure warning light illuminates to
indicate a TPMS malfunction.
For additional information, see "Tire Pressure
Monitoring System (TPMS)" in the "5. Start-
ing and driving" section.
WARNING
•Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
•If the light does not illuminate with the
ignition switch pushed ON, have the ve-
hicle checked. It is recommended you
visit an INFINITI retailer for this service.
•If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, 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 in-
crease the likelihood of tire failure. Seri-
ous 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 illumi-
nates while driving after adjusting the
tire pressure, a tire may be flat. If you
have a flat tire, replace it with a replace-
ment tire as soon as possible.
•If a replacement tire is mounted or a
wheel is replaced without a TPMS sen-
sor tire pressure 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 ve-
hicle's tires replaced and/or TPMS sys-
tem 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.
Malfunction Indicator light
(MIL) (yellow)
When the ignition switch is turned to the ON
position, the yellow Malfunction Indicator
light illuminates. This means that the system
is operational.
If the yellow engine malfunction indicator
light lights up while the engine is running,
there may be a fault, for example:
•In the engine management
•In the fuel injection system
•In the exhaust system
•In the ignition system (for vehicles with
gasoline engines)
•In the fuel system
•In other monitored items, for example the
automatic transmission.
2-10Instruments and controls

•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.
Starting and driving5-5

The vehicle's wheels have sensors fitted that
monitor the tire pressures in all four tires The
tire pressure monitor warns you if the pres-
sure 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 min-
utes of driving, the current tire pressure of
each tire is shown in the [Serv.] menu of the
vehicle information display.
WARNING
•Radio waves could adversely affect
electrical medical equipment. Those who
use a pacemaker should contact their
electrical medical equipment manufac-
turer for the possible influences before
use.
•If the low tire pressure warning light il-
luminates or a tire pressure-related
warning is displayed by the vehicle in-
formation display while driving, avoid
sudden steering maneuvers or abrupt
braking, 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 likeli-
hood of tire failure. Serious vehicle dam- age could occur and may lead to an acci-
dent and could result in serious personal
injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the tire and loading informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a replacement tire as
soon as possible.
•If a replacement wheel is fitted without
an INFINITI TPMS Sensor, the TPMS
will not function and the low tire pres-
sure warning light will flash for approxi-
mately 1 minute. The light will remain on
after 1 minute. It is recommended you
contact an INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.
•For models with run-flat tires, although
you can continue driving with a punc-
tured run-flat tire, remember that ve-
hicle handling stability is reduced, which
could lead to an accident and personal
injury. Also, driving a long distance at
high speeds may damage the tires. – Do not drive at speeds above 50
MPH (80 km/h) and do not drive
more than approximately 93 miles
(150 km) with a punctured run-flat
tire. The actual distance the vehicle
NSD660
5-6Starting and driving

can be driven on a flat tire depends on
outside temperature, vehicle load,
road conditions and other factors.
– If you detect any unusual sounds or
vibrations while driving with a punc-
tured run-flat tire, pull off the road to
a safe location and stop the vehicle as
soon as possible. The tire may be se-
riously damaged and need to be re-
placed.
•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 repair-
ing or replacing the tire (for models
equipped with the emergency tire punc-
ture repair kit). It is recommended you
visit an INFINITI retailer for this service.
•INFINITI recommends using only
INFINITI Genuine Emergency Tire Seal-
ant provided with your vehicle. Other
tire sealants may damage the valve stem
seal which can cause the tire to lose air
pressure (for models equipped with the
emergency tire puncture repair kit).
CAUTION
•The TPMS may not function properly
when the wheels are equipped with
snow chains or the wheels are buried in
snow.
•Do not place metallized film or any metal
parts (antenna, etc.) on the windows.
This may cause poor reception of the
signals from the tire pressure sensors,
and the TPMS will not function
properly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pres-
sure suitable for the operating situation (see
"Wheels and tires" in the "8. Do-it-yourself"
section). Note that the correct tire pressure
for the current operating situation must first
be taught-in to the tire pressure monitor (see
"Restarting TPMS" later in this section).
If there is a substantial loss of pressure, the
warning threshold for the warning message
is aligned to the reference values taught-in.
Restart the tire pressure monitor after ad-
justing to the cold tire pressure. The current
pressures are saved as new reference values.
This will ensure that a warning message will
only appear if the tire pressure drops signifi-
cantly. The tire pressure monitor does not warn you
of an incorrectly set tire pressure.
TPMS is not able to warn you of a sudden
loss of pressure, e. g. if the tire is penetrated
by a foreign object. In the event of a sudden
loss of pressure, bring the vehicle to a halt by
braking carefully. Avoid abrupt steering ma-
neuvers.
TPMS has a yellow warning light in the com-
bination meter for indicating a pressure loss
or malfunction. Depending on how the warn-
ing light flashes or lights up, a tire pressure
that is too low or a malfunction in TPMS is
indicated:
•If the warning light is lit continuously, the
tire pressure on one or more tires is signifi-
cantly too low. TPMS is not malfunction-
ing.
•If the warning light flashes for around a
minute and then remains lit constantly, the
TPMS is malfunctioning.
In addition to the warning light, a message
appears in the vehicle information display.
Observe the information on display mes-
sages (see "Safety systems" in the "2. Instru-
ments and controls" section
It may take up to ten minutes for a malfunc-
tion of the tire pressure monitor to be indi-
cated. A malfunction will be indicated by the
Starting and driving5-7

•Keep your engine tuned up.
•Follow the recommended scheduled
maintenance.
•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.
For additional information, see "Recom-
mended fluids/lubricants and capacities"
in the "10. Technical information" section
WARNING
•Do not drive beyond the performance
capability of the tires, even with 4WD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), 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 at-
tempt 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 drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle 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 dyna-
mometer. Using the wrong test equip-
ment may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage or
personal injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.

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 recognize run-flat tires by the mark-
ing which appears on the tire side wall. You
will find this marking next to the tire size
designation, 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
vehicle is partially laden and approximately
20 miles (30 km) when the vehicle is fully
laden.NIC2686
6-4In case of emergency

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.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure
loss warning appears in the vehicle informa-
tion display.
You must not exceed a maximum speed of 50
MPH (80 km/h).
When replacing one or all tires, observe the
following specifications for your vehicle's
tires:
•Size
•Type
•Run-flat mark
If a tire has gone flat and cannot be replaced
with a run flat tire, a standard tire may be
used as a temporary measure. Make sure that
you use the proper size and type (summer or
winter tire).
WARNING
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneu-
vers, and driving over obstacles (curbs, pot
holes, off road). This applies in particular to
a laden vehicle.
Stop driving in emergency mode if:
•You hear banging noises.
•The vehicle starts to shake.
•You see smoke and smell rubber.
•VDC is intervening constantly.
•There are tears in the sidewalls of the
tire.
After driving in emergency mode, have the
wheel rims checked with regard to their
further use. It is recommended you visit an
INFINITI retailer for this service. The faulty
tire must be replaced.
