Checking the tire pressure

1. Remove the valve stem cap from

the tire.

2. P r e s s t h e p r e s s u r e g a u g e

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

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

1 Tire 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,

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.

facturer, brand and/or model name
molding that is higher or deeper than
the same molding on the other side-
wall 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
(Example: 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 may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.

Replacing tires with those not originally

specified by INFINITI could affect the
proper operation of the TPMS.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty Infor-
mation Booklet.

All season tires

INFINITI specifies all season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S (Mud and Snow) 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
substantially 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 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 prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires. Skid and traction capabilities of
studded snow tires, on wet or dry surfaces,
may be poorer than that of non-studded
snow tires.

TIRE CHAINS

Use of tire chains may be prohibited
according to location. Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
proper size for the tires on your vehicle and
are installed according to the chain man-
ufacturer’s suggestions. Use only SAE
Class S chains. Class “S” chains are used
on vehicles with restricted tire to vehicle
clearance. Vehicles that can use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
the tire and the closest vehicle suspension
or body component required to accommo-
date the use of a winter traction device (tire
chains or cables). The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the
tire chain 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 addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling

and performance may be adversely af-
fected.

Tire chains must be installed only on the
rear wheels and not on the front wheels.

Never install tire chains on a TEMPORARY
USE ONLY spare tire.

Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.

CHANGING WHEELS AND TIRES

Tire rotation (Models equipped with
same size tires on all wheels)

INFINITI recommends rotating the
tires every 7,500 miles (12,000 km).
(See “Flat tire” (P.6-3) for tire repla-
cing procedures.)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

Wheel nut tightening torque:

80 ft-lb (108 N·m)

The wheel nuts must be kept tigh-
tened to the specification at all
times. It is recommended that wheel
nuts be tightened to the specifica-
tion at each tire rotation interval.

WARNING

. After rotating the tires, check and

adjust the tire pressure.

. Retighten the wheel nuts when

the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).

. Do not include the T-type spare

tire or any other small size spare
tire in the tire rotation.

. For additional information regard-

ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in
the Warranty Information Booklet.

Tire rotation (Models equipped with
different size tires on front and
rear)

Tires cannot be rotated on this
vehicle, as front tires are a different
size from rear tires.
A pin is on the front brake rotor to
prevent the rear wheels from being
installed in place of the front wheels.
The spare tire can be installed in
place of the front and rear wheels.
When installing the spare tire in the
front wheel, the hole in the spare tire
wheel must be aligned with the pin
on the brake rotor.

WARNING

. Retighten the wheel nuts when

the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).

WARNING

. Tires should be periodically in-

spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced.

. The original tires have built-in

tread wear indicators. When wear
indicators are visible, the tire(s)
should be replaced.

. Tires degrade with age and use.

Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.

. Improper service of the spare tire

may result in serious personal
injury. If it is necessary to repair
the spare tire, contact an INFINITI
retailer.

Replacing wheels and tires

When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications” (P.9-8) for recommended
types and sizes of tires and wheels.)

WARNING

The use of tires other than those
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted or radial), or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-tire
clearance, tire chain clearance, speed-
ometer calibration, headlight aim and
bumper height. Some of these effects
may lead to accidents and could result in
serious personal injury.

For Two-Wheel Drive (2WD) models, if
your vehicle was originally equipped
with 4 tires that were the same size
and you are only replacing 2 of the 4
tires, install the new tires on the rear
axle. Placing new tires on the front axle
may cause loss of vehicle control in
some driving conditions and cause an

accident and personal injury.

If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased brak-
ing efficiency and/or early brake pad/
shoe wear. See “Wheels and tires” (P.9-
9) of this manual for wheel off-set
dimensions.

When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.

Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.

Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without

warning.

The use of retread tire is not recom-
mended.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty Infor-
mation Booklet.

All-Wheel Drive (AWD) models

CAUTION

Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer case
and differential gears.

ONLY use spare tires specified for the
AWD model.

If excessive tire wear is found, it is
recommended that all four tires be re-

pressure and wheel alignment should also
be checked and corrected as necessary.
Contact an INFINITI retailer.

Wheel balance

Unbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There-
fore, they should be balanced as required.

Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.

For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.

Care of wheels

See “Cleaning exterior” (P.7-2) for details
about care of the wheels.

Spare tire (TEMPORARY USE ONLY
(T-type) spare tire)

Observe the following precautions if the T-
type spare tire must be used, otherwise

your vehicle could be damaged or involved
in an accident.

WARNING

The T-type spare tire should be used for
emergency use. It should be replaced
with the standard tire at the first
opportunity to avoid possible tire or
differential damage.

Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.

Periodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire at
60 psi (420 kPa, 4.2 bar). Always keep
the pressure of the full size spare tire (if
so equipped) at the recommended pres-
sure for standard tires, as indicated on
the Tire and Loading Information label.
For Tire and Loading Information label
location, see “Tire and Loading Informa-
tion label” in the index of this manual.

With the TEMPORARY USE ONLY spare
tire installed do not drive your vehicle at
speeds faster than 50 MPH (80 km/h).

When driving on roads covered with
snow or ice, the TEMPORARY USE ONLY
spare tire should be used on the front
wheels and original tire used on the rear
wheels (drive wheels). Use tire chains
only on the two rear original tires.

Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than
the standard tire. Replace the spare tire
as soon as the tread wear indicators
appear.

Do not use the spare tire on other
vehicles.

Do not use more than one spare tire at
the same time.

CAUTION

Do not use tire chains on a TEMPORARY
USE ONLY spare tire. Tire chains will not
fit properly and may cause damage to
the vehicle.

Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also do not drive

FUEL INFORMATION

VQ37VHR engine

Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number
96).

If premium gasoline is not available,
unleaded regular gasoline with an octane
rating of 87 AKI number (Research octane
number 91) 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

acceleration.

Use unleaded premium gasoline for max-
imum vehicle performance.

CAUTION

Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
warranty coverage.

Under no circumstances should a leaded
gasoline be used, because this will
damage 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
adversely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the INFINITI new vehicle
limited warranty.

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.

Gasoline specifications

INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter (WWFC)
specifications where it is available. Many
of the automobile manufacturers devel-
oped this specification to improve emis-
sion system and vehicle performance. Ask
your service station manager if the gaso-

line meets the World-Wide Fuel Charter
(WWFC) specifications.

Reformulated gasoline

Some fuel suppliers are now producing
reformulated gasolines. These gasolines
are specially designed to reduce vehicle
emissions. INFINITI supports efforts to-
wards cleaner air and suggests that you
use reformulated gasoline when available.

Gasoline containing oxygenates

Some fuel suppliers sell gasoline contain-
ing oxygenates such as ethanol, MTBE and
methanol with or without advertising their
presence. INFINITI does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your INFINITI
cannot be readily determined. If in doubt,
ask your service station manager.

If you use oxygenate-blend gasoline,
please take the following precautions as
the usage of such fuels may cause vehicle
performance problems and/or fuel system
damage.

. The fuel should be unleaded and have

an octane rating no lower than that
recommended for unleaded gasoline.

Condition:

-------------------------------------------------------------------------------------------------------------------------------------------------------------

Black plate (455,1)

[ Edit: 2012/ 7/ 6 Model: V36-D ]

. If an oxygenate-blend, excepting a

methanol blend, is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)

. E-15 fuel contains more than 10%

oxygenate. E-15 fuel will adversely
affect the emission control devices
and systems of the vehicle and should
not be used. Damage caused by such
fuel is not covered by the INFINITI new
vehicle limited warranty.

. If a methanol blend is used, it should

contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not
available to ensure that all methanol
blends are suitable for use in INFINITI
vehicles.

If any undesirable driveability problems
such as engine stalling or hard hot starting
are experienced after using oxygenate-

blend fuels, immediately change to a
non-oxygenate fuel or a fuel with a low
blend of MTBE.

Take care not to spill gasoline during
refueling. Gasoline containing oxygenates
can cause paint damage.

E-15 fuel

E-15 fuel is a mixture of approximately
15% fuel ethanol and 85% unleaded
gasoline. E-15 can only be used in vehicles
designed to run on E-15 fuel. Do not use E-
15 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.

E-85 fuel

E-85 fuel is a mixture of approximately
85% fuel ethanol and 15% unleaded
gasoline. E-85 can only be used in a
Flexible Fuel Vehicle (FFV). Do not use E-
85 fuel in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square,
orange and black label with the common
