∙ 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 light does not illuminate with the ignition switch placed in the ON position,
have the vehicle checked as soon as pos-
sible. It is recommended that 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 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.

∙ 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

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.

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.
6-4In case of emergency

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. statesand 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.
Frequently check the tire pressure and adjust
pressure of each tire properly. The tire pres-
sure can be also checked in the vehicle infor-
mation display.
It can be difficult to tell if a run-flat tire is
under-inflated or flat. Check the tire pres-
sures as described in this section. If the tire
becomes under-inflated while driving, the
low tire pressure warning light will illuminate
and the “Tire Pressure Low – Add Air” warn-
ing appears in the vehicle information display.
If the tire becomes flat while driving, the low
tire pressure warning light and the “Flat Tire –
Visit dealer" warning will appear.
Low tire pressure:
If the vehicle is being driven with low tire
pressure, the low tire pressure warning light
will illuminate and the “Tire Pressure Low –
Add Air” warning appears in the vehicle infor-
mation display.
Flat tire:
If the vehicle is being driven with one or more
flat tires, the low tire pressure warning light
will illuminate continuously and a chime will
sound for 10 seconds. A “Flat-Tire – Visit
dealer" warning also appears in the vehicle
information display.
The chime will only sound at the first indica-
tion of a flat tire and the warning light will
illuminate continuously. When the flat tire
warning is activated, have the system reset
and the tire checked and replaced if neces-
sary. It is recommended that you visit an
INFINITI retailer for this service. Even if the
tire is inflated to the specified COLD tire
pressure, the warning light will continue to
illuminate until the system is reset. It is recom-
mended that you visit an INFINITI retailer for
this service.

Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. For addi-
tional information, refer to “Wheels and tires”
in the “Technical and consumer information”
section of this manual.
WARNING
∙ The use of tires other than those recom-mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can
adversely affect the ride, braking, han-
dling, VDC system, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, headlight
aim and bumper height. Some of these
effects may lead to accidents and could
result in serious personal injury.
∙ For 2WD models, if your vehicle was originally equipped with four tires that
were the same size and you are only re-
placing two of the four tires, install the
new tires on the rear axle. Placing new
tires on the front axle may cause loss of
vehicle control in some driving conditions
and cause an accident and personal
injury. ∙ If the wheels are changed for any reason,
always replace with wheels which have
the same off-set dimension. Wheels of a
different off-set could cause premature
tire wear, degrade vehicle handling char-
acteristics, affect the VDC system
and/or interference with the brake discs.
Such interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information on
wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical and
consumer information” section of this
manual.
∙ 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 this service.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the TPMS.
∙ The TPMS sensor may be damaged if it is not handled correctly. Be careful when
handling the TPMS sensor. ∙ When replacing the TPMS sensor, the ID
registration may be required. It is recom-
mended that you visit an INFINITI re-
tailer for ID registration.
∙ Do not use a valve stem cap that is not specified by INFINITI. The valve stem cap
may become stuck.
∙ Be sure that the valve stem caps are cor- rectly fitted. Otherwise the valve may be
clogged up with dirt and cause a malfunc-
tion or loss of pressure.
∙ Do not install a damaged or deformed wheel or tire even if it has been repaired.
Such wheels or tires could have structural
damage and could fail without warning.
∙ The use of retread tires is not recommended.
∙ 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.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
