If you have a flat tire, see “FLAT TIRE” in the “6. In
case of emergency” section.
TIRE PRESSURE
Tire Pressure Monitoring System (TPMS)
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
CHECK TIRE PRESSURE warning appears on the
dot matrix liquid crystal display, one or more of
your 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 more details, see “Low tire pressure warning
light” in the “2. Instruments and controls” sec-
tion, “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “5. Starting and driving” section
and “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “6. In case of emergency” section.
Tire inflation pressure
Check the pressure of the tires (includ-
ing the spare) often and always prior to
long distance trips. The recommended
tire pressure specifications are shownon the Tire and Loading Information
label under the “Cold Tire Pressure”
heading. The Tire and Loading Informa-
tion 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.
Incorrect tire pressure, including under
inflation, may adversely affect tire life
and vehicle handling.
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. label. The vehicle weight ca-
pacity is indicated on the Tire and Load-
ing Information label. Do not load your
vehicle beyond this capacity. Overload-
ing your vehicle may result in reduced
tire life, unsafe operating conditions
due to premature tire failure, or unfavor-
able handling 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 Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.

Maintenance and do-it-yourself8-27

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 whipping action damage to
the fenders or underbody. If possible, avoid
fully loading your vehicle 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.
Tire chains must be installed only on the rear
wheels and not on the front wheels.
Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with
tire chains in such conditions can cause dam-
age to the various mechanisms of the vehicle
due to some overstress.
CHANGING WHEELS AND TIRES
Tire rotation
Tires cannot be rotated on this vehicle
because the front tires are a different
size than the rear tires.
A pin is on the front brake rotor to
prevent the rear wheels from being in-
stalled in place of the front wheels. Thespare tire can be installed in place of the
front and rear wheels. When installing
the spare tire in the front wheel, the hole
in the spare tire wheel must be aligned
with the pin on the brake rotor.
WARNING
●Retighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
●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.1. Wear indicator

Tire wear and damage
WARNING
●Tires should be periodically inspected
for wear, cracking, bulging or objects
caught in the tread. If excessive wear,
cracks, bulging or deep cuts are found,
the tire(s) should be replaced.
SDI1663
Maintenance and do-it-yourself8-33

●The original tires have built-in tread
wear indicators. When wear indicators
are visible, the tire(s) should be
replaced.
●Tires degrade with age and use. Have
tires, including the spare, over 6 years
old checked by a qualified technician,
because some tire damage may not be
obvious. Replace the tires as necessary
to prevent tire failure and possible per-
sonal injury.
●Improper service of the spare tire may
result in serious personal injury. If it is
necessary to repair the spare tire, con-
tact an INFINITI retailer.
●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.
Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity as originally equipped. (See “SPECIFICATIONS”
in the “9. Technical and consumer information”
section for recommended types and sizes of
tires and wheels.)
WARNING
●
The use of tires other than those recom-
mended or the mixed use of tires of different
brands, construction (bias, bias-belted or ra-
dial), or tread patterns can adversely affect
the ride, braking, handling, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration, head-
light aim and bumper height. Some of these
effects may lead to accidents and could re-
sult in serious personal injury.
●
If the wheels are changed for any reason, al-
ways replace with wheels which have the
same off-set dimension. Wheels of a different
off-set could cause premature tire wear, de-
grade vehicle handling characteristics and/or
interference with the brake discs/drums. Such
interference can lead to decreased braking ef-
ficiency and/or early brake pad/shoe wear.
See “WHEELS AND TIRES” in the “9. Technical
and consumer information” section of this
manual for wheel off-set dimensions.
● When a spare tire is mounted or a wheel is
replaced, 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. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
● 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 tire is not recommended.
● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.

Wheel balance
Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can
get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be performed with
the wheels off the vehicle. Spin balancing the
wheels on the vehicle could lead to mechanical
damage.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
INFINITI Warranty Information Booklet.
Care of wheels
●Wash the wheels when washing the vehicle
to maintain their appearance.
● Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
● Do not use abrasive cleaners when washing
the wheels.
● Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
● INFINITI recommends that the road wheels
be waxed to protect against road salt in
areas where it is used during winter.
Emergency tire puncture repair kit (if
so equipped)
The emergency tire puncture repair kit (Emer-
gency Tire Sealant) is supplied with the vehicle
instead of a spare tire. It can be used to
temporarily repair minor tire punctures.
If possible, have the vehicle towed to a facility
that can repair or replace the flat tire. Using the
emergency tire puncture repair kit may cause a
malfunction of the tire pressure sensor and
cause the low tire pressure warning light to
illuminate.
See “FLAT TIRE” in the “6. In case of emer-
gency” section for more details.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire) (if so equipped)
Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident.
WARNING
● The T-type spare tire should be used for
emergency use. It should be replaced with
the standard tire at the first opportunity to
avoid possible tire or differential damage.
● Drive carefully while the TEMPORARY USE
ONLY spare tire is installed. Avoid sharp
turns and abrupt braking while driving.
● Periodically check spare tire inflation pres-
sure. Always keep the pressure of the TEM-
PORARY USE ONLY spare tire at 60 psi (420
kPa, 4.2 bar). Always keep the pressure of
the full size spare tire (if so equipped) at the
recommended pressure for standard tires,
as indicated on the Tire and Loading Infor-
mation label. For Tire and Loading Informa-
tion label location, see “Tire and Loading
Information label” in the index of this
manual.
● With the TEMPORARY USE ONLY spare tire
installed do not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
Maintenance and do-it-yourself8-35

●When driving on roads covered with snow or
ice, the TEMPORARY USE ONLY spare tire
should be used on the front wheels and origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the two rear
original tires.
● Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than the
standard tire. Replace the spare tire as soon
as the tread wear indicators appear.
● Do not use the spare tire on other vehicles.
● Do not use more than one spare tire at the
same time.
CAUTION
● Do not use tire chains on a TEMPORARY USE
ONLY spare tire. Tire chains will not fit prop-
erly and may cause damage to the vehicle.
● Because the TEMPORARY USE ONLY spare
tire is smaller than the original tire, ground
clearance is reduced. To avoid damage to the
vehicle, do not drive over obstacles. Also do
not drive the vehicle through an automatic
car wash since it may get caught.
