adjust every time the brake pedal is applied.
WARNING
Have your brake system checked if the
brake pedal height does not return to nor-
mal. It is recommended that you visit an
INFINITI retailer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched scraping
or screeching sound will be heard when the
vehicle is in motion. The noise will be heard
whether or not the brake pedal is depressed.
Have the brakes checked as soon as possible
if the wear indicator sound is heard. Under some driving or climate conditions, oc-
casional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does
not affect the function or performance of the
brake system.
Proper brake inspection intervals should be
followed.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all tires
except the spare. When the low tire
pressure warning light is lit and the
“Tire Pressure Low – Add Air” warning
appears in the vehicle information dis-
play, one or more of your tires is sig-
nificantly under-inflated. If equipped,
the system also displays pressure of all
tires (except the spare tire) on the dis- play screen by sending a signal from a
sensor that is installed in each wheel.
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 pres-
sure (for example a flat tire while
driving).
For additional information, see “Low
tire pressure warning light” (P. 2-13),
“Tire Pressure Monitoring System
(TPMS)” (P. 5-5) and “Flat tire” (P. 6-3).
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on
the F.M.V.S.S./C.M.V.S.S. certifica-
tion label or the Tire and Loading In-
formation label under the “Cold Tire
Pressure” heading. The Tire and Load-
ing Information label is affixed to the
driver 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 mod-
erate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
see “TPMS with tire inflation indicator”
(P. 5-8).
WHEELS AND TIRES
Do-it-yourself8-27

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.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”
warning 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.
8-36Do-it-yourself

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.
If the low tire pressure warning light illumi-
nates continuously and the “Flat Tire – Visit
dealer" warning appears in the vehicle infor-
mation display:
• Do not exceed 50 mph (80 km/h).
• Increase your following distance to allowfor increased stopping distances.
• Avoid sudden maneuvers, hard cornering and hard braking.
WARNING
• Although you can continue driving with a
punctured 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 tire. •
Do not drive at speeds above 50 mph (80
km/h) and do not drive more than ap-
proximately 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, read 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 punctured
run-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
possible 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 rec-
ommended 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 neces-
sary. It is recommended 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, see “Wheels and tires”
(P. 10-9).
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 condi-
tions 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 de-
creased braking efficiency and/or early
brake pad wear. For additional informa-
tion on wheel off-set dimensions, see
“Wheels and tires” (P. 10-9).
• When using 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 approxi-
mately 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 mal-
function 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 struc-
tural 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.
