WARNING HIGH VOLTAGE
When xenon headlights are on, they pro-
duce a high voltage. To prevent an electric
shock, never attempt to modify or disas-
semble. Always have your xenon headlights
replaced at an INFINITI retailer. For addi-
tional information, see “ Headlight and turn
signal switch ” (P.2-34).
Use the same number and wattage shown
in the following chart as originally in-
stalled.
If replacement is required, see an INFINITI
retailer.
Fog may temporarily form inside the lens of
the exterior lights in the rain or in a car
wash. A temperature difference between
the inside and the outside of the lens
causes the fog. This is not a malfunction. If
large drops of water collect inside the lens,
contact an INFINITI retailer. EXTERIOR AND INTERIOR LIGHTS GUID-BDE3C310-75C1-4F4D-9E48-5E09104465DA

TIRE PRESSURE GUID-059CBC2D-BB1C-4DE2-B26E-A89198E003F1
Tire Pressure Monitoring System
(TPMS) GUID-54149EBD-6C2B-4EEC-AE1A-FDADBBA021B3
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 ” (P.2-15), “ Tire Pressure
Monitoring System (TPMS) ” (P.5-4) and
“ Tire Pressure Monitoring System (TPMS) ”
(P.6-2).
Tire inflation pressure GUID-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 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
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 pressure GUID-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 LABELING GUID-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.

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. SDI1607
