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”in the“9. Technical and
consumer information” section for recom-
mended 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” 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 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.
Maintenance and do-it-yourself8-39

8-40Maintenance and do-it-yourself
If excessive tire wear is found, it is
recommended that all four tires be re-
placed 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.
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” in the“Appearance
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
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
the vehicle through an automatic car
wash since it may get caught.

CAPACITIES AND RECOMMENDED FUEL/
LUBRICANTS

above symptoms are encountered, have
your vehicle checked at an INFINITI retailer
or other competent service facility.
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.

ENGINE OIL AND OIL FILTER RE-
COMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see“Capacities and recommended fuel/
lubricants” earlier in this section. INFINITI
recommends the use of an energy conser-
ving oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification 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.
Technical and consumer information9-5

9-6Technical and consumer information
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 important 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 recommended
could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When
replacing, 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 reduce engine life.
Damage to engines caused by improper
maintenance or use of incorrect oil andfilter quality and/or viscosity is not covered
by the new INFINITI vehicle limited warran-
ties.
Your engine was filled with a high quality
engine oil when it was built. You do not
have to change the oil before the first
recommended change interval. Oil and
filter change intervals depend upon how
you use your vehicle. Operation under the
following conditions may require more
frequent oil and filter changes.
.
repeated short distance driving at cold
outside temperatures,
. driving in dusty conditions,
. extensive idling,
. stop and go “rush hour”traffic,
Refer to the “INFINITI Service and Main-
tenance Guide” for the maintenance sche-
dule.AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT RE-
COMMENDATIONS
The air conditioning system in your
INFINITI vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN A/C system oil Type S
or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant
will cause severe damage to the air con-
ditioning system and will require the repla-
cement 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 re-
covery and recycling of any refrigerant
during automotive air conditioning system
service. Your INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.
Contact an INFINITI retailer when servicing
your air conditioning system.
