GUID-464D8334-4B6E-4650-8810-2AA00D8EFD2DAdditional information on the following
items with “*”is found later in this
section.
Outside the vehicleGUID-D21012E2-ED85-45D5-B3C1-02A03AE3EF12The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Doors and engine hood: Check that all
doors and the engine hood, operate
properly. Also ensure that all latches lock
securely. Lubricate hinges, latches, latch
pins, rollers and links if necessary. Make
sure that the secondary latch keeps the
hood from opening when the primary latch is released.
When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
Lights*:
Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and
other lights are all operating properly and
installed securely. Also check headlight
aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Tires should be rotated
every 7,500 miles (12,000 km). If your
vehicle is equipped with different sized
tires in the front and rear, tires cannot be
rotated.
Tires*: Check the pressure with a gauge
often and always prior to long distance
trips. If necessary, adjust the pressure in
all tires, including the spare, to the
pressure specified. Check carefully for
damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and cap when the tires are replaced due to
wear or age.
Tire, wheel alignment and balance:
If the
vehicle should pull to either side while
driving on a straight and level road, or if
you detect uneven or abnormal tire wear,
there may be a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.

Tire Pressure Monitoring System
(TPMS)
GUID-54149EBD-6C2B-4EEC-AE1A-FDADBBA021B3This 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” (P.2-15),“Tire Pressure
Monitoring System (TPMS)” (P.5-4) and
“Tire Pressure Monitoring System (TPMS)”
(P.6-2).
Tire inflation pressureGUID-FDC2587E-609D-4595-9387-574BE1BDEAC6
Check the pressure of the tires
(including the spare) often and al- ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure”
heading. The
Tire and Loading 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 whendriven 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.
Incorrect tire pressure, including
under inflation, may adversely affect
tire life and vehicle handling.
WARNING
.Improperly inflated tires can fail
suddenly 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 capacity is indicated on
the Tire and Loading Information
label. Do not load your vehicle
beyond this capacity. Overloading
your vehicle may result in reduced
tire life, unsafe operating condi-
tions due to premature tire failure,
or unfavorable handling character-
istics 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

Checking the tire pressureGUID-CC708595-2C70-4CAE-BDC3-D716681157B7
1.Remove the valve stem cap from
the tire.
2.Press the pressure gauge
squarely onto the valve stem. Do
not press too hard or force the
valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard
while checking the pressure, re-
position 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 la-
bel.
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, including the spare.

Federal law requires tire manufac-
turers to place standardized informa-
tion on the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.

8-42Maintenance and do-it-yourself
.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 personal injury.
. Improper service of the spare tire
may result in serious personal
injury. If it is necessary to repair
the spare tire, contact an INFINITI
retailer.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.Replacing wheels and tiresGUID-4EF95767-87A1-46D1-823F-01023BAE60AAWhen replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications” (P.9-8) for recommended
types and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted or radial), or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-tire
clearance, tire chain clearance, speed-
ometer calibration, headlight aim and
bumper height. Some of these effects
may lead to accidents and could result in
serious 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 characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased brak- ing efficiency and/or early brake pad/
shoe wear. See
“Wheels and tires” (P.9-
9) 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 remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement 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 struc-
tural damage and could fail without
warning.
. The use of retread tire is not recom-
mended.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or“Tire Safety Infor-
mation” (Canada) in the Warranty Infor-
mation Booklet.

All-Wheel Drive (AWD) modelsGUID-0EB56D0C-6EAC-46F4-9C56-5E4540701594
CAUTION
.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
damage the transmission, transfer case
and differential gears.
. ONLY use spare tires specified for the
AWD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed 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.
Contact an INFINITI retailer.
Wheel balanceGUID-E8819382-6D86-409C-A6FD-5113A53508ABUnbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There-
fore, they should be balanced as required. Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.

GUID-3D33E4D2-DC59-460C-941C-8160D646B5B6Observe 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
pressure. Always keep the pressure of
the TEMPORARY 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 pres-
sure for standard tires, as indicated on
the Tire and Loading Information label.
For Tire and Loading Information label
location, see “Tire and Loading Informa-
tion 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).
. When driving on roads covered with
snow or ice, the TEMPORARY USE ONLY
spare tire should be used on the front
wheels and original 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
