2018 INFINITI QX30 flat tire

A booster seat should be used until the child
can pass the seat belt fit test below:
•Are the child’s back and hips against the
vehicle seatback?
•Is the child able to sit without slouching?
•Do the child’s knees bend easily over the
front edge of the seat with feet flat on the
floor?
•Can the child safely wear the seat belt (lap
belt low and snug across the hips and
shoulder belt across mid-chest and shoul-
der)?
•Is the child able to use the properly ad-
justed head restraint/headrest?
•Will the child be able to stay in position for
the entire ride?
If you answered no to any of these questions,
the child should remain in a booster seat us-
ing a three-point type seat belt.
NOTE
Laws in some communities may follow dif-
ferent guidelines. Check local and state
regulations to confirm your child is using the
correct restraint system before traveling.
WARNING
Never let a child stand or kneel on any seat
and do not allow a child in the cargo area.
The child could be seriously injured or killed
in a sudden stop or collision.

sistance (see "Brake system" in the "5. Start-
ing and driving" section).
BRAKE warning light (red)
WARNING
•Your brake system may not be working
properly if the warning light is on. Driv-
ing could be dangerous. If you judge it to
be safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because driving
it could be dangerous.
•Pressing the brake pedal when the igni-
tion switch is not in the ON position
and/or when the brake fluid level is low
may increase the stopping distance and
braking will require greater pedal effort
as well as pedal travel.
•If the brake fluid level is below the mini-
mum or MIN mark on the brake fluid res-
ervoir, do not drive until the brake sys-
tem has been checked. It is
recommended that you visit an INFINITI
retailer for this service.
When the ignition switch is placed in the ON
position, the light remains illuminated and
turns off when the engine is started. If the light illuminates at any other time, it may
indicate that the brake system is not func-
tioning properly. If the BRAKE warning light
illuminates, stop the vehicle immediately and
contact an INFINITI retailer.
This light functions for both the parking brake
and the foot brake systems.
Low tire pressure warning
light (if equipped)
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors the
tire pressure of all its tires.
The low tire pressure warning light warns of
low tire pressure or indicates that the TPMS
is not functioning properly.
When the ignition switch is in the ON posi-
tion, the Low tire pressure warming light illu-
minates to indicate that the system is opera-
tional. The light then tuns off within a few
seconds after the engine is started.
Low tire pressure warning:
If the vehicle is being driven with low tire
pressure, the warning light will illuminate. A
tire pressure warning message also appears
in the vehicle information display.
When the low tire pressure warning light il-
luminates, you should stop and adjust the
tire pressure of all 4 tires to the recom- mended COLD tire pressure shown on the
Tire and Loading Information label located in
the driver's door opening, see "Tire and load-
ing information label" in the "9. Mainte-
nance and Schedules" section. The low tire
pressure warning light does not automati-
cally turn off when the tire pressure is ad-
justed. After the tire is inflated to the recom-
mended pressure, the vehicle must be 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 ap-
pears each time the ignition switch is placed
in the ON position as long as the low tire
pressure warning light remains illuminated.
For additional information, see "Vehicle in-
formation display" later in this section and
"Tire Pressure Monitoring System (TPMS)" in
the "5. Starting and driving" section.
TPMS malfunction:
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is placed in the ON position. The light
will remain on after 1 minute. Have the sys-
tem checked. It is recommended that you visit
an INFINITI retailer for this service. The low
tire pressure warning does not appear if the
Instruments and controls2-9

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.

Tires
MessagePossible causes/consequences and solutions
[Please Correct Tire
Pressure] The tire pressure is too low in at least one of the tires, or the tire pressure difference between the wheels is too great.
1. Check the tire pressures at the next opportunity (see "Wheels and tires" in the "8. Do-it-yourself" section)
2. If necessary, correct the tire pressure.
3. Restart the tire pressure monitoring system (see "Restarting TPMS" in the "5. Starting and driving" section)
[Check Tire(s)] The tire pressure in one or more tires has dropped significantly The wheel position is displayed in the vehicle information display
A warning tone also sounds.
WARNING
Underinflated tires pose the following risks:•The tires may burst, especially as the load and vehicle speed increase.•The tires may wear excessively and/or unevenly, which may greatly impair tire traction.•The driving characteristics, as well as steering and braking, may be greatly impaired.
There is a risk of an accident.
1. Stop the vehicle without making any sudden steering or braking maneuvers. Pay attention to the traffic conditions as you do so.
2. Secure the vehicle against rolling away.
3. Check the tires and, if necessary, follow the instructions for a flat tire (see "Flat tire" in the "6. In case of emergency" section).
4. Check the tire pressures and, if necessary, correct the tire pressure.
[Warning Tire Malfunction] The tire pressure in one or more tires has dropped suddenly. The wheel position is displayed in the vehicle information display.
WARNING
If you drive with a flat tire, there is a risk of the following hazards:•A flat tire affects the ability to steer or brake the vehicle.•You could lose control of the vehicle.•Continued driving with a flat tire will cause excessive heat buildup and possibly a fire.
There is a risk of an accident.
1. Stop the vehicle without making any sudden steering or braking maneuvers. Pay attention to the traffic conditions as you do so.
2. Secure the vehicle against rolling away.
3. Check the tires and, if necessary, follow the instructions for a flat tire (see "Flat tire" in the "6. In case of emergency" section).
2-52Instruments 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

restraint system” section of this manual, and
also instruct your passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers.In a rollover crash, an
unbelted or improperly belted person is sig-
nificantly more likely to be injured or killed
than a person properly wearing a seat belt.
OFF-ROAD RECOVERY
While driving, the right side or left side wheels
may unintentionally leave the road surface. If
this occurs, maintain control of the vehicle by
following the procedure below. Please note
that this procedure is only a general guide.
The vehicle must be driven as appropriate
based on the conditions of the vehicle, road
and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
4.
When appropriate, slowly release the accel-
erator pedal to gradually slow the vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while vehicle
speed is reduced. Do not attempt to drive
the vehicle back onto the road surface
until vehicle speed is reduced. 6. When it is safe to do so, gradually turn the
steering wheel until both tires return to
the road surface. When all tires are on the
road surface, steer the vehicle to stay in
the appropriate driving lane.
If you decide that it is not safe to return
the vehicle to the road surface based on
vehicle, road or traffic conditions, gradu-
ally slow the vehicle to a stop in a safe
place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving on
under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially at
highway speeds.
Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspect the tires for wear and damage. For
additional information, refer to “Wheels and
tires” in the “Maintenance and do-it-yourself”
section of this manual. If a tire rapidly loses air
pressure or “blows-out” while driving, main-
tain control of the vehicle by following the
procedure below. Please note that this pro-
cedure is only a general guide. The vehicle must be driven as appropriate based on the
conditions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
•The vehicle generally moves or pulls in
the direction of the flat tire.
•Do not rapidly apply the brakes.
•Do not rapidly release the accelerator
pedal.
•Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
3. When appropriate, slowly release the ac- celerator pedal to gradually slow the ve-
hicle.
4. Gradually steer the vehicle to a safe loca- tion off the road and away from traffic if
possible.
