2018 INFINITI QX30 spare tire

•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 system will not operate at speeds
below approximately 40 MPH (60
km/h) or if it cannot detect lane mark-
ers.
•The LDW system is primarily intended
for use on well-developed freeways or
highways. It may not detect the lane
markers in certain roads, weather or
driving conditions.
•Do not use the LDW system under the
following conditions as it may not func-
tion properly: – During bad weather (rain, fog, snow,
etc.).
– When driving on slippery roads, such
as on ice or snow, etc.
– When driving on winding or uneven
roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshift or tem-
porary lane.
– When driving on roads where the lane
width is too narrow.
– When driving without normal tire
conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-standard
wheels). –
When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.
•The camera may not detect lane markers
in the following situations and the LDW
system may not operate properly. – On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-
standard lane markers; or lane mark-
ers covered with water, dirt, snow,
etc.
– On roads where the discontinued lane
markers are still detectable.
– On roads where there are sharp
curves.
– On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts, seams
or lines remaining after road repairs.
(The LDW system could detect these
items as lane markers.)
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion does not align with the lane
marker.
– When traveling close to the vehicle in
front of you, which obstructs the lane
camera unit detection range. –
When rain, snow or dirt adheres to
the windshield in front of the lane
camera unit.
– When the headlights are not bright
due to dirt on the lens or if the aiming
is not adjusted properly.
– When strong light enters the lane
camera unit. (For example, the light
directly shines on the front of the ve-
hicle at sunrise or sunset.)
– When a sudden change in brightness
occurs. (For example, when the ve-
hicle enters or exits a tunnel or under
a bridge.)
– When there is poor visibility. (For ex-
ample, due to insufficient illumina-
tion of the road, or due to snow, rain,
fog or spray.
– When there is glare. (For example,
from oncoming traffic, the sun or re-
flection when the road is wet).
5-34Starting and driving

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.
REMOVING AND FITTING

are clear of the wheel and use gloves as
necessary to avoid injury.
Installing the wheel
WARNING
•A temporary use spare wheel and tire is
designed for emergency use.
•Never use wheel bolts other than those
provided with your vehicle. Incorrect
wheel bolts or improperly tightened
wheel bolts may cause the wheel to be-
come loose or come off. This could cause
an accident.
•Never use oil or grease on the wheel
bolts. This may cause the wheel bolts to
become loose.

If you have a flat tire, refer to "Flat tire" in the
"6. In case of emergency" section.
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 to "Tire
Pressure Monitoring System (TPMS)" in the
"5. Starting and driving" section.
Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips.
The recommended tire pressure specifica-
tions are shown on the F.M.V.S.S./
C.M.V.S.S. label or the Tire and Loading In-
formation label (if so equipped) under the
Cold Tire Pressure heading. The Tire and
Loading Information label is affixed to thedriver side center pillar. Tire pressures should
be checked regularly because:
•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 sud-
denly and cause an accident.
•The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S. S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on the
Tire and Loading Information label (if so
equipped). Do not load your vehicle be-
yond this capacity. Overloading your
vehicle may result in reduced tire life,
unsafe operating conditions due to pre-
mature tire failure, or unfavorable han-
dling characteristics and could also lead
to a serious accident. Loading beyond
the specified 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
pressure gauge to ensure that the tire
pressures are at the specified level.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.

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

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the side-
wall of all tires. This information identifies
and describes the fundamental characteris-
tics of the tire and also provides the tire iden-
tification number (TIN) for safety standard
certification. The TIN can be used to identify
the tire in case of a recall.

3Tire ply composition and material
The number of layers or plies of rubber-
coated fabric in the tire. Tire manufactur-
ers also must indicate the materials in the
tire, which include steel, nylon, polyester,
and others.
4Maximum permissible inflation pressure
This number is the greatest amount of air
pressure that should be put in the tire. Do
not exceed the maximum permissible in-
flation pressure.
5Maximum load rating
This number indicates the maximum load
in kilograms and pounds that can be car-
ried by the tire. When replacing the tires
on the vehicle, always use a tire that has
the same load rating as the factory in-
stalled tire.
6Term of “tubeless” or “tube type”
Indicates whether the tire requires an in-
ner tube (“tube type”) or not (“tubeless”).
7The word “radial”
The word “radial” is shown, if the tire has
radial structure.
8Manufacturer or brand name”
Manufacturer or brand name is shown.
Other tire-related terminology:
In addition to the many terms that are de-
fined throughout this section, Intended Out-
board Sidewall is (1) the sidewall that con-
tains a whitewall, bears white lettering or
bears manufacturer, brand and/or model
name molding that is higher or deeper than
the same molding on the other sidewall of the
tire, or (2) the outward facing sidewall of an
asymmetrical tire that has a particular side
that must always face outward when
mounted on a vehicle.
TYPES OF TIRES
WARNING
•When changing or replacing tires, be
sure all four tires are of the same type
(i.e, summer, all season or snow) and
construction. An INFINITI retailer may
be able to help you with information
about tire type, size, speed rating and
availability.
•Replacement tires may have a lower
speed rating than the factory equipped
tires, and they may not match the po-
tential maximum vehicle speed. Never
exceed the maximum speed rating of the
tire.
•Always use tires of the same type, size,
brand, construction and tread pattern
on all four wheels. Failure to do so may
result in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunction
resulting in personal injury or death, ex-
cessive tire wear and may damage the
transmission, transfer case and differ-
ential gears.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation“ (Canada) in the Warranty In-
formation Booklet.
CAUTION
ONLY use spare tires specified for the
model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
that you visit an INFINITI retailer for this
service.
