Infiniti M37 (2011 year). Manual

Replacing wheels and tires

When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. (See “SPECIFICATIONS”
in the “9. Technical and consumer information”
section for recommended types and sizes of
tires and wheels.)

WARNING

● The use of tires other than those recom-

mended or the mixed use of tires of different
brands, construction (bias, bias-belted or ra-
dial), or tread patterns can adversely affect
the ride, braking, handling, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration, head-
light aim and bumper height. Some of these
effects may lead to accidents and could re-
sult in serious personal injury.

● If the wheels are changed for any reason,

always replace with wheels which have the
same off-set dimension. Wheels of a differ-
ent off-set could cause premature tire wear,
degrade vehicle handling characteristics
and/or

interference

with

the

brake

discs/drums. Such interference can lead to
decreased braking efficiency and/or early
brake pad/shoe wear. See “WHEELS AND
TIRES” in the “9. Technical and consumer
information” section 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 re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment 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 structural damage
and could fail without warning.

● The use of retread tire is not recommended.

● For additional information regarding tires,

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

Intelligent All-Wheel Drive (AWD)
models

CAUTION

● Always use tires of the same type, size,

brand, construction (bias, bias-belted or ra-
dial), 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 Intel-

ligent AWD 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 nec-
essary. 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. Therefore, they should be
balanced as required.

Wheel balance service should be performed 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 Booklet.

Care of wheels

See “CLEANING EXTERIOR” in the “7. Appear-
ance and care” section 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 pres-

sure. Always keep the pressure of the TEM-
PORARY 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 pressure for standard tires,
as indicated on the Tire and Loading Infor-
mation label. For Tire and Loading Informa-
tion label location, see “Tire and Loading
Information 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 origi-
nal 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.

● Do not tow a trailer when the TEMPORARY

USE ONLY spare tire is installed.

CAUTION

● Do not use tire chains on a TEMPORARY USE

ONLY spare tire. Tire chains will not fit prop-
erly 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 the vehicle through an automatic
car wash since it may get caught.

FUEL RECOMMENDATION

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 pos-
sible.

● Avoid full throttle driving and abrupt accel-

eration.

However, for maximum vehicle performance, the
use of unleaded premium gasoline is recom-
mended.

CAUTION

● Using a fuel other than that specified could

adversely affect the emission control sys-
tem, 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-85 fuel in your vehicle. Your

vehicle is not designed to run on E-85 fuel.
Using E-85 fuel can damage the fuel system
components and is not covered by the
INFINITI vehicle limited warranty.

Gasoline specifications

INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifica-
tions where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission system and vehicle perfor-
mance. Ask your service station manager if the
gasoline meets the World-Wide Fuel Charter
(WWFC) specifications.

Reformulated gasoline

Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
INFINITI supports efforts towards cleaner air
and suggests that you use reformulated gaso-
line when available.

Gasoline containing oxygenates

Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and metha-
nol with or without advertising their presence.
INFINITI does not recommend the use of fuels of

which the oxygenate content and the fuel com-
patibility 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 prob-
lems and/or fuel system damage.

● The fuel should be unleaded and have an oc-

tane rating no lower than that recommended
for unleaded gasoline.

● 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%.)

● If a methanol blend is used, it should contain

no more than 5% methanol (methyl alcohol,
wood alcohol). It should also contain a suit-
able amount of appropriate cosolvents and
corrosion inhibitors. If not properly formu-
lated with appropriate cosolvents and corro-
sion inhibitors, such methanol blends may
cause fuel system damage and/or vehicle
performance problems. At this time, suffi-
cient 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 experi-

墍

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

enced after using oxygenate-blend fuels, imme-
diately 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-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. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.

Aftermarket fuel additives

INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.

Octane rating tips

Using unleaded gasoline with an octane rating
lower than recommended above can cause per-
sistent, heavy spark knock. (Spark knock is a
metallic rapping noise.) If severe, this can lead
to engine damage. If you detect a persistent
heavy spark knock even when using gasoline of
the stated octane rating, or if you hear steady
spark knock while holding a steady speed on
level roads, have an INFINITI retailer correct the
condition. Failure to correct the condition is mis-
use of the vehicle, for which INFINITI is not re-
sponsible.

Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.

However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.

CAUTION

● Your vehicle is not designed to run on E-85

fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.

● E-85 is a mixture of approximately 85% fuel

ethanol and 15% unleaded gasoline.

● U.S. government regulations require ethanol

dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.

ENGINE OIL AND OIL FILTER
RECOMMENDATION

Selecting the correct oil

It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure sat-
isfactory engine life and performance, see “CA-
PACITIES AND RECOMMENDED FUEL/ LUBRI-
CANTS”

earlier

this

section.

INFINITI

recommends the use of an energy conserving
oil in order to improve fuel economy.

Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE viscos-
ity standard. These oils have the API certifica-
tion mark on the front of the container. Oils
which do not have the specified quality label
should not be used as they could cause engine
damage.

Oil additives

INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used and
maintenance intervals are followed.

Oil which may contain foreign matter or has
been previously used should not be used.

Oil viscosity

The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant that the engine oil viscosity be selected
based on the temperatures at which the vehicle
will be operated before the next oil change.
Choosing an oil viscosity other than that recom-
mended could cause serious engine damage.

Selecting the correct oil filter

Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When replac-
ing, use the genuine oil filter or its equivalent
for the reason described in change intervals.

Change intervals

The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than
the specified quality, or oil and filter change
intervals longer than recommended could re-
duce engine life. Damage to engines caused by
improper maintenance or use of incorrect oil
and filter quality and/or viscosity is not covered
by the new INFINITI vehicle limited warranties.

Your engine was filled with a high quality
engine oil when it was built. You do not have to

墍

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

change the oil before the first recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle. Opera-
tion under the following conditions may require
more frequent oil and filter changes.

● repeated short distance driving at cold out-

side temperatures,

● driving in dusty conditions,
● extensive idling,
● stop and go “rush hour” traffic,

Refer to the “INFINITI Service and Maintenance
Guide” for the maintenance schedule.

AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS

The air conditioning system in your INFINITI ve-
hicle must be charged with the refrigerant HFC-
134a (R-134a) and the lubricant, NISSAN A/C sys-
tem oil Type S or the exact equivalents.

CAUTION

The use of any other refrigerant or lubricant will
cause severe damage to the air conditioning
system and will require the replacement of all
air conditioner system components.

The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s ozone
layer. Although this refrigerant does not affect
the earth’s atmosphere, certain governmental
regulations require the recovery and recycling
of any refrigerant during automotive air condi-
tioning system service. Your INFINITI retailer
has the trained technicians and equipment
needed to recover and recycle your air condi-
tioning system refrigerant.

Contact an INFINITI retailer when servicing your
air conditioning system.

If you plan to travel in another country, you
should first find out if the fuel available is
suitable for your vehicle’s engine.

Using fuel with too low an octane rating may
cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline.
Therefore, avoid taking your vehicle to areas
where appropriate fuel is not available.

When transferring the registration of your ve-
hicle to another country, state, province or dis-
trict, it may be necessary to modify the vehicle
to meet local laws and regulations.

The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ.

When any vehicle is to be taken into another
country, state, province or district and regis-
tered, its modifications, transportation, and reg-
istration are the responsibility of the user.
INFINITI is not responsible for any inconvenience
that may result.
