HEADLIGHTS
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.

If you have a flat tire, see ªFLAT TIREº in the ª6. In
case of emergencyº 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, 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 ªLow tire pressure warn-
ing lightº in the ª2. Instruments and controlsº
section, ªTire Pressure informationº in the ª4.
Monitor, climate, audio, phone and voice rec-
ognition systemsº section, ªTIRE PRESSURE
MONITORING SYSTEM (TPMS)º in the ª5. Start-
ing and drivingº section and ªTIRE PRESSURE
MONITORING SYSTEM (TPMS)º in the ª6. In case
of emergencyº 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 shown
on the Tire and Loading Information
label under the ªCold Tire Pressureº
heading. The Tire and Loading Informa-
tion label is affixed to the driver side
center pillar. Tire pressures should be
checked regularly because:
cMost tires naturally lose air over time.
cTires 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
cImproperly inflated tires can fail sud-
denly and cause an accident.
cThe Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on
the Tire and Loading Information la-
bel. Do not load your vehicle beyond
this capacity. Overloading your ve-
hicle may result in reduced tire life,
unsafe operating conditions due to
premature tire failure, or unfavorable
handling characteristics and could
also lead to a serious accident. Load-
ing beyond the specified capacity
may also result in failure of other ve-
hicle components.

cBefore 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 pressure
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 side-
ways, or air will escape. If the hissing
sound of air escaping from the tire is
heard while checking the pressure,
reposition the gauge to eliminate this
leakage.
3.Remove the gauge.
4.Read the tire pressure on the gauge
stem and compare it to the specifica-
tion shown on the Tire and Loading
Information label.
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 re-
lease air as needed.
6.Install the valve stem cap.
7.Check the pressure of all other tires,
including the spare.

TIRE LABELING
Federal law requires tire manufacturers
to place standardized information on the
sidewall of all tires. This information
identifies and describes the fundamen-
tal 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.
s1Tire size (example: P215/60R16 94H)
1.P: The ªPº indicates the tire is de-
signed for passenger vehicles. (Not all
tires have this information.)
2.Three-digit number (215): This num-
ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
3.Two-digit number (60): This number,
known as the aspect ratio, gives the
tire's ratio of height to width.
4.R: The ªRº stands for radial.
5.Two-digit number (16): This number 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 be-
cause it is not required by law.
7.H: Tire speed rating. You should not
drive the vehicle faster than the tire
speed rating.

can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
s6Term of ªtubelessº or ªtube typeº
Indicates whether the tire requires an
inner tube (ªtube typeº) or not
(ªtubelessº).
s7The word ªradialº
The word ªradialº is shown, if the tire
has radial structure.
s8Manufacturer or brand name

white lettering or bears manufacturer,
brand and/or model name molding that
is higher or deeper than the same mold-
ing on the other sidewall of the tire, or
(2) the outward facing sidewall of an
asymmetrical tire that has a particular
side that must always face outward
when mounted on a vehicle.
TYPES OF TIRES
WARNING
cWhen changing or replacing tires, be sure all
four tires are of the same type (Example:
Summer, All Season or Snow) and construc-
tion. An INFINITI retailer may be able to help
you with information about tire type, size,
speed rating and availability.
c Replacement tires may have a lower speed
rating than the factory equipped tires, and
may not match the potential maximum ve-
hicle speed. Never exceed the maximum
speed rating of the tire.
c Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS. c
For additional information regarding tires,
refer to ªImportant Tire Safety Informationº
(US) or ªTire Safety Informationº (Canada) in
the Warranty Information Booklet.
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 (Mud and Snow) on the tire side-
wall. 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 substantially re-
duced 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 handling of your
vehicle.
Generally, snow tires will have lower speed
ratings 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 pattern 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 capa-
bilities of studded snow tires, on wet or dry
surfaces, may be poorer than that of non-
studded snow tires.
