8-4Maintenance and do-it-yourself
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.
Windshield: Clean the windshield on a
regular basis. Check the windshield at
least every six months for cracks or other
damage. Have a damaged windshield
repaired by a qualified repair facility.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
Inside the vehicleGUID-9BC72144-3F74-486E-818A-C3F8D037D67DThe maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc. Accelerator pedal:
Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism: On a fairly steep hill, check that your
vehicle is held securely with the selector
lever in the P (Park) position without
applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, see an INFINITI retailer
immediately. Keep the floor mat away from
the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed

TIRE PRESSUREGUID-059CBC2D-BB1C-4DE2-B26E-A89198E003F1
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.6-3).
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
are at the specified level.

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.

TIRE LABELINGGUID-7CDDB6DE-92AD-4E32-995B-54060312AD14
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.
SDI1606
Example*1Tire size (example: P215/60R16
94H)
1.P: The
“P”indicates the tire is
designed for passenger vehicles.
(Not all tires have this informa-
tion.)
2.Three-digit number (215): This
number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge.
3.Two-digit number (60): This num-
ber, known as the aspect ratio,

gives the tire’s ratio of height to
width.
4.R: The“R”stands for radial.
5.Two-digit number (16): This num-
ber is the wheel or rim diameter in
inches.
6.Two- or three-digit number (94):
This number is the tire’s load
index. It is a measurement of
how much weight each tire can
support. You may not find this
information on all tires because it
is not required by law.
7.H: Tire speed rating. You should
not drive the vehicle faster than
the tire speed rating.

1.DOT: Abbreviation for the “Depart-
ment of Transportation”. The sym-
bol can be placed above, below or
to the left or right of the Tire
Identification Number.
2.Two-digit code: Manufacturer’s
identification mark
3.Two-digit code: Tire size
4.Three-digit code: Tire type code
(Optional)
5.Three-digit code: Date of Manu-
facture
6.Four numbers represent the week
and year the tire was built. For
example, the numbers 3103
means the 31st week of 2003. If
these numbers are missing, then
look on the other sidewall of the
tire.
*3Tire ply composition and materi-
al
The number of layers or plies of
rubber-coated fabric in the tire.
Tire manufacturers also must
indicate the materials in the tire,
which include steel, nylon,
