Tire and Loading Information label
1Seating capacity: The maximum number
of occupants that can be seated in the
vehicle.
2Vehicle load limit: See "Vehicle loading
information".
3Original size: The size of the tires origi-
nally installed on the vehicle at the fac-
tory.
4Cold tire pressure: Inflate the tires to this
pressure when the tires are cold. Tires are
considered COLD after the vehicle has
been parked for 3 or more hours, ordriven less than 1 mile (1.6 km) at moder-
ate speeds. The recommended cold tire
inflation is set by the manufacturer to
provide the best balance of tire wear,
vehicle handling, driveability, tire noise,
etc., up to the vehicle’s GVWR.

TIRE INFLATION PRESSURE
Checking 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 sideways, or air will
escape. If the hissing sound of air escap-
ing 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 specification 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 release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, in-
cluding the spare.

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the side-
wall of all tires. This information identifies
and describes the fundamental characteris-
tics of the tire and also provides the tire iden-
tification number (TIN) for safety standard
certification. The TIN can be used to identify
the tire in case of a recall.
SDI1949ZSDI1575Z
Example
8-30Do-it-yourself

1Tire size (example: P215/60R16 94H)
1 P: The “P” indicates the tire is designed for
passenger vehicles. (Not all tires have this
information.)
2 Three-digit number (215): This number
gives the width in millimeters of the tire
from sidewall edge to sidewall 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 “R” 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 num-
ber 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.
7H:Tire speed rating. You should not drive the
vehicle faster than the tire speed rating.
2TIN (Tire Identification Number) for a new
tire (example: DOT XX XX XXX XXXX)
1 DOT: Abbreviation for the “Department of
Transportation”. The symbol can be placed
above, below or to the left or right of the
Tire Identification Number.
2 Two-digit code: Manufacturer’s identifi-
cation mark
3 Two-digit code: Tire size
4 Three-digit code: Tire type code (Optional)
5 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 material
The number of layers or plies of rubber-
coated fabric in the tire. Tire manufactur-
ers also must indicate the materials in thetire, which include steel, nylon, polyester,
and others.
4Maximum permissible inflation pressure
This number is the greatest amount of air
pressure that should be put in the tire. Do
not exceed the maximum permissible in-
flation pressure.
5Maximum load rating
This number indicates the maximum load
in kilograms and pounds that can be car-
ried by the tire. When replacing the tires
on the vehicle, always use a tire that has
the same load rating as the factory in-
stalled tire.
6Term of “tubeless” or “tube type”
Indicates whether the tire requires an in-
ner tube (“tube type”) or not (“tubeless”).
7The word “radial”
The word “radial” is shown, if the tire has
radial structure.
8Manufacturer or brand name”
Manufacturer or brand name is shown.
Other tire-related terminology:
In addition to the many terms that are de-
fined throughout this section, Intended Out-
board Sidewall is (1) the sidewall that con-
tains a whitewall, bears white lettering or

•Tires degrade with age and use. Have
tires, including the spare, over 6 years
old checked by a qualified technician be-
cause some tire damage may not be ob-
vious. 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, it is
recommended that you visit an INFINITI
retailer for this service.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
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 should be
replaced immediately.
The original tires have a built-in tread wear
indicator. When the wear indicator is visible,
the tire should be replaced.
Improper servicing of a tire may result in se-
rious personal injury. If it is necessary to re-pair a tire, it is recommended you contact an
INFINITI retailer.
TIRE ROTATION
INFINITI recommends rotating the tires ev-
ery 5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer to "Flat tire".As soon as
possible, tighten the wheel nuts to the speci-
fied torque with a torque wrench.
Wheel nut tightening torque: 96 ft-lb
(130 N·m)
The wheel nuts must be kept tightened to
specifications at all times. It is recommended
that wheel nuts be tightened to specification
at each tire rotation interval.
WARNING
•After rotating the tires, check and ad-
just the tire pressure.
•Do not include the spare tire in the tire
rotation.
•For additional information regarding
tires, refer to "Important Tire Safety
Information" (US) or "Tire Safety Infor-
mation" in the Warranty Information
Booklet.
REPLACING WHEELS AND TIRES
WARNING
Do not install a deformed wheel or tire even
if it has been repaired. Such wheels or tires
could have structural damage and could
fail without warning.
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. (See "Wheels and Tires"
for recommended types and sizes of tires and
wheels.)
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle handling characteristics
and/or interference with the brake discs/
drums. Such interference can lead to de-
creased braking efficiency and/or early brake
pad/shoe wear.
Confirm the following for the TPMS:
WARNING
•The use of tires other than those recom-
mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can
8-34Do-it-yourself

Before driving a loaded vehicle, confirm that
you do not exceed the Gross Vehicle Weight
Rating (GVWR) or the Gross Axle Weight
Rating (GAWR) for your vehicle. (See "Mea-
surement of weights" later in this section.)
Also check tires for proper inflation pres-
sures. See the Tire and Loading Information
label.
LOADING TIPS
•The GVW must not exceed GVWR or
GAWR as specified on the F.M.V. S.S./
C.M.V.S.S. certification label.
•Do not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
WARNING
•Properly secure all cargo to help prevent
it from sliding or shifting. Do not place
cargo higher than the seatbacks. In a
sudden stop or collision, unsecured
cargo could cause personal injury.
•Do not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts of your
vehicle can break, tire damage could oc-
cur, or it can change the way your ve-
hicle handles. This could result in loss of
control and cause personal injury.
•Overloading could not only shorten the
life of your vehicle and the tires, but also
could cause unsafe vehicle handling and
longer braking distances. This may
cause a premature tire failure which
could result in a serious accident and
personal injury. Failures caused by over-
loading are not covered by the vehicle's
warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight shifts
that could affect the balance of your vehicle.
When the vehicle is loaded, drive to a scale
and weigh the front and the rear wheels
separately to determine axle loads. Individual
axle loads should not exceed either of the
gross axle weight ratings (GAWR). The total
of the axle loads should not exceed the gross
vehicle weight rating (GVWR). These ratings
are given on the vehicle certification label. If
weight ratings are exceeded, move or remove
items to bring all weights below the ratings.Your vehicle was designed to be used to carry
passengers and luggage
CAUTION
Do not tow a trailer with your vehicle.
TRAILER TOWING
Technical information10-15

DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must con-
form to federal safety requirements in addi-
tion to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one and
one-half (1 1/2) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon ac-
tual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
TRACTION AA, A, B AND C
The traction grades, from highest to lowest,
are AA, A, B and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of as-
phalt and concrete. A tire marked C may have
poor traction performance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to dissi-
pate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance which
all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levels
of performance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
build-up and possible tire failure.

FUEL INFORMATION
Gasoline engine
CAUTION
Do not use leaded gasoline. Using leaded
gasoline will damage the three-way catalyst.
2.0L gasoline engine model:
Use unleaded premium gasoline with an oc-
tane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 95).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 89 AKI number (Research oc-
tane number 93) may be temporarily used,
but only under the following precautions:
•Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as pos-
sible.
•Avoid full throttle driving and abrupt ac-
celeration.
Use unleaded premium gasoline for maxi-
mum vehicle performance.
CAUTION
•Using a fuel other than that specified
could adversely affect the emission con-trol system, and may also affect war-
ranty coverage.
•Under no circumstances should a leaded
gasoline be used, because this will dam-
age the three-way catalyst.
•Do not use E-15 or E-85 fuel in your
vehicle. Your vehicle is not designed to
run on E-15 or E-85 fuel. Using E-15 or
E- 85 fuel in a vehicle not specifically
designed for E-15 or E-85 fuel can ad-
versely affect the emission control de-
vices and systems of the vehicle. Dam-
age caused by such fuel is not covered by
the INFINITI new vehicle limited war-
ranty.
•U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region.
