2019 INFINITI QX50 spare tire location

∙ 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 perma-
nently damage the tires and increase the
likelihood of tire failure. Serious vehicle
damage could occur and may lead to an
accident and could result in serious per-
sonal injury or death. Check the tire pres-
sure for all four tires. Adjust the tire pres-
sure to the recommended COLD tire
pressure show on the Tire and Loading
Information label 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 or the
TPMS may be malfunctioning. If you
have a flat tire, replace it with a replace-
ment tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service. ∙ When replacing a wheel without the
TPMS such as the spare tire, 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 tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that 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 theregular 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 the four wheels correctly.

Instruments and controls2-13

∙ If the low tire pressure warning light illu-minates 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 likelihood of
tire failure. Serious vehicle damage could
occur and may lead to an accident 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
replacement tire as soon as possible. (For
additional information, refer to “Flat
tire” in the “In case of emergency” section
for changing a flat tire.) ∙ When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is re-
placed, 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 re-
main on after 1 minute. Have your tires
replaced and/or TPMS system reset as
soon as possible. It is recommended that
you visit an INFINITI retailer for this
service.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the TPMS.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
CAUTION
∙ The TPMS may not function properlywhen the wheels are equipped with tire
chains or the wheels are buried in snow.
∙ Do not place metalized film or any metal parts (antenna, etc.) on the windows.
This may cause poor reception of the sig-
nals from the tire pressure sensors, and
the TPMS will not function properly. Some devices and transmitters may tempo-
rarily interfere with the operation of the
TPMS and cause the low tire pressure warn-
ing light to illuminate.
Some examples are:
∙ Facilities or electric devices using similar radio frequencies are near the vehicle.
∙ If a transmitter set to similar frequencies is being used in or near the vehicle.
∙ If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may illu-
minate in the following cases: ∙ If the vehicle is equipped with a wheel and tire without TPMS.
∙ If the TPMS has been replaced and the ID has not been registered.
∙ If the wheel is not originally specified by INFINITI.
Starting and driving5-7

To shut off the engine in an emergency situ-
ation while driving, perform the following
procedure:
– Rapidly push the push-button ignitionswitch three consecutive times in less than
1.5 seconds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires. When the low tire pres-
sure warning light is lit, and the “Tire Pressure
Low - Add Air” warning appears in the vehicle
information display, one or more of your tires
is significantly under-inflated. The system
also displays pressure of all tires (except the
spare tire) on the vehicle information display
screen by sending a signal from a sensor that
is installed in each wheel. If the vehicle is
being driven with low tire pressure, the TPMS
will activate and warn you of it by the low tire
pressure warning light. This system will acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional in-
formation, refer to “Warning lights, indicator
lights and audible reminders” in the “Instru-
ments and controls” section and “Tire Pres-
sure Monitoring System (TPMS)” in the
“Starting and driving” sections of this manual.
WARNING
∙ Radio waves could adversely affect elec-tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
∙ If the low tire pressure warning light illu- minates 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 likelihood of
tire failure. Serious vehicle damage could
occur and may lead to an accident 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 replacement tire as soon as possible.

In case of emergency6-3

∙ When replacing a wheel without TPMSsuch as the spare tire, TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that 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.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
RUN-FLAT TIRES
This vehicle is equipped with run-flat tires.
Run-flat tires can be used temporarily if they
are punctured. When the “Flat Tire — Visit
Dealer” warning appears in the vehicle infor-
mation display, one or more of your tires is
punctured. For additional information, refer
to “Run-flat tires” in the “Do-it-yourself” sec-
tion of this manual.
For additional information, refer to the tire
safety information in the Warranty Informa-
tion Booklet.
WARNING
∙ Although you can continue driving with apunctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and per-
sonal 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 dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature, ve-
hicle load, road conditions and other
factors.
∙ Drive safely at reduced speeds. Avoid hard cornering or braking, which may
cause you to lose control of the vehicle.
∙ If you detect any unusual sounds or vi- brations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously dam-
aged and need to be replaced.
CAUTION
∙ Never install tire chains on a puncturedrun-flat tire, as this could damage your
vehicle.
∙ Avoid diving over any projection or pot- hole, as the clearance between the ve-
hicle and the ground is smaller than
normal.
∙ Do not enter an automated car wash with a punctured run-flat tire.
∙ Have the punctured tire inspected by an INFINITI retailer or other authorized re-
pair shop. Replace the tire as soon as pos-
sible if the tire is seriously damaged.
6-4In case of emergency

∙ Always use tires of the same type, size,brand, construction and tread pattern on
all four wheels. Failure to do so may re-
sult in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunction re-
sulting in personal injury or death, exces-
sive tire wear and may damage the trans-
mission, transfer case and differential
gears.
∙ For additional information regarding tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
All-Wheel Drive (AWD) models
CAUTION
∙ ONLY use spare tires specified for the AWD 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 nec-
essary. It is recommended that you visit an
INFINITI retailer for this service.
All season tires
INFINITI specifies All Season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
Season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires
have better snow traction than All Season
tires and may be more appropriate in some
areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating
“M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use
of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle. Generally, snow tires have lower speed rat-
ings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of
the tire.
If you install snow tires, they must be the
same size, brand, construction and tread pat-
tern on all four wheels.
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 ca-
pabilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
Run–Flat Tires
Your vehicle is equipped with run-flat tires
and is not equipped with a spare tire, or a jack
and tool kit. The jack and tool kit may be
purchased at the dealer. Please consult an
INFINITI retailer for additional information.
You can continue driving to a safe location
even if the run-flat tires are punctured. Al-
ways use run-flat tires of the specified size on
all four wheels. Mixing tire sizes or construc-
tion may reduce vehicle handling stability. If
necessary, it is recommended that you visit an
INFINITI retailer for this service.

CAUTION
∙ Never install tire chains on a puncturedrun-flat tire, as this could damage your
vehicle.
∙ Avoid driving over any projection or pot- hole, as the clearance between the ve-
hicle and the ground is smaller than
normal.
∙ Do not enter an automated car wash with a punctured run-flat tire.
∙ Have the punctured tire inspected by an INFINITI retailer or other authorized re-
pair shop. Replace the tire as soon as pos-
sible if the tire is seriously damaged.
∙ Always use tires of the same type, size, brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears (AWD models).
∙ ONLY use spare tires specified for the AWD model. ∙ If excessive tire wear is found, it is recom-
mended that all four tires be replaced
with tires of the same size, brand, con-
struction 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.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on 255/45R20 size tires. Installation of
the tire chains/cables on 255/45R20 size
tires will cause damage to the vehicle. If you
plan to use tire chains/cables, you should
install 235/55R19 size tires on your
vehicle.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size for
the tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions. Use only SAE class “S” chains. Class
“S” chains are used on vehicles with restricted
tire to vehicle clearance. Vehicles that can use
Class “S” chains are designed to meet the
minimum clearances between the tire and the closest vehicle suspension or body compo-
nent required to accommodate the use of a
winter traction device (tire chains or cables).
The minimum clearances are determined us-
ing the factory equipped tire size. Other types
may damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose end
links of the tire chain must be secured or
removed to prevent the possibility of whip-
ping action damage to the fenders or under-
body. If possible, avoid fully loading your ve-
hicle when using tire chains. In addition, drive
at a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely affected.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.

CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires every 7,500 miles (12,000 km).
For additional information on tire re-
placing procedures, refer to “Flat tire”
in the “In case of emergency” section
of this manual.
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.Wheel nut tightening torque:
83 ft-lb (113 N·m)
The wheel nuts must be kept tight-
ened to specifications at all times. It is
recommended that wheel nuts be
tightened to specification at each tire
rotation interval.
WARNING
∙ After rotating the tires, check and adjust the tire pressure.
∙ Retighten the wheel nuts when the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
∙ Do not include the spare tire in the tire rotation.
∙ For additional information re- garding tires, refer to “Important
Tire Safety Information” (US) or
