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”

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
bears manufacturer, brand and/or model
name molding that is higher or deeper than
the same molding 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
•When changing or replacing tires, be
sure all four tires are of the same type
(i.e, summer, all season or snow) and
construction. An INFINITI retailer may
be able to help you with information
about tire type, size, speed rating and
availability.
•Replacement tires may have a lower
speed rating than the factory equipped
tires, and they may not match the po-
tential maximum vehicle speed. Never
exceed the maximum speed rating of the
tire.
•Always use tires of the same type, size,
brand, construction and tread pattern
on all four wheels. Failure to do so may
result in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunction
resulting in personal injury or death, ex-
cessive tire wear and may damage the
transmission, transfer case and differ-
ential gears.
•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.
CAUTION
ONLY use spare tires specified for the
model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced 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. It is recommended
that you visit an INFINITI retailer for this
service.

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 on the tire sidewall. 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 sub-
stantially reduced 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 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 han-
dling of your vehicle.Generally, snow tires have lower speed rat-
ings 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 ca-
pabilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
Four-Wheel Drive (4WD) models
If excessive tire wear is found, it is recom-
mended that all four tires be replaced 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. It is recommended
that you visit an INFINITI retailer.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on 235/45 R19 or 235/50 R18 size tires.
Installation of the tire chains/cables on
235/45 R19 or 235/50 R18 size tires will
cause damage to the vehicle. If you plan to
use tire chains/cables, you should install
215/60 R17 size tires on your vehicle.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure that they are of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer’s in-
structions.
Use chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chains must be
secured or removed to prevent the possibility
of whipping action damage to the fenders or
underbody. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Tire chains must be installed only on the
front wheels and not on the rear wheels.

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" in the "6. In
case of emergency" section.As soon as pos-
sible, tighten the wheel nuts to the specified
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 In-
formation" (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" in
the "9. Maintenance and Schedules" section
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
adversely affect the ride, braking, han-
dling, VDC system, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, head-
light aim and bumper height. Some of
these effects may lead to accidents and
could result in serious personal injury.
•For 2WD models, if your vehicle was
originally equipped with 4 tires that
were the same size and you are only re-
placing 2 of the 4 tires, install the new
tires on the rear axle. Placing new tires
on the front axle may cause loss of ve-
hicle control in some driving conditions
and cause an accident and personal in-
jury.
•If the wheels are changed for any rea-
son, always replace with wheels which
have the same offset dimension. Wheels
of a different offset could cause prema-
ture tire wear, degrade vehicle handling
characteristics, affect the VDC system
and/or interference with the brake
discs. Such interference can lead to de-
creased braking efficiency and/or early

ENGINE SPECIFICATIONS
Technical information10-7

This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety sys-
tems for a short period of time, typically 30
seconds or less. The EDR in this vehicle is
designed to record such data as:
•How various systems in your vehicle were
operating.
•Whether or not the driver and passenger
safety belts were buckled/fastened.
•How far (if at all) the driver was depressing
the accelerator and/or brake pedal.
•How fast the vehicle was traveling.
•Sounds are not recorded.
This data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur.
NOTE: EDR data are recorded by your ve-
hicle only if a nontrivial crash situation occurs;
no data are recorded by the EDR under nor-
mal driving conditions and no personal data
(e.g. name, gender, age and crash location)
are recorded. However, other parties, such as
law enforcement, could combine the EDR data with the type of personally identifying
data routinely acquired during a crash inves-
tigation.
To read data recorded by an EDR, special
equipment is required and access to the ve-
hicle or the EDR is needed. In addition to the
vehicle manufacturer and INFINITI retailer,
other parties, such as law enforcement, that
have the special equipment, can read the in-
formation if they have access to the vehicle or
the EDR. EDR data will only be accessed with
the consent of the vehicle owner or lessee or
as otherwise required or permitted by law.

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
possible.
•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
