Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Using engine oil and
filters that are not of the specified quality, or
exceeding recommended oil and filter change
intervals could reduce 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 New
Vehicle Limited Warranty.
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 Maintenance
Guide” for the maintenance schedule.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system of your vehicle must
be charged with the refrigerant HFC-134a and
the lubricant INFINITI A/C System Oil Type S or
the exact equivalents.
CAUTION
The use of any other refrigerant or oil may
cause severe damage to the air conditioning
system and will require the replacement of all
air conditioner system components.
The refrigerant HFC-134a in your vehicle will not
harm the Earth’s ozone layer. However, it may
contribute in a small part to the global warming
effect.
Certain government regulations require the re-
covery and recycling of any refrigerant during
automotive air conditioner system service. An
INFINITI retailer has the trained technicians and
equipment needed to recover and recycle your
air conditioner system refrigerant.
It is recommended that you visit an INFINITI
retailer when servicing your air conditioner sys-
tem.

DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable
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 gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1 1/2) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices 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 mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. 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, cor-
nering, 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 dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma-
terial 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 rep-
resent higher levels of performance on the
laboratory test wheel than the minimum re-
quired 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 separately or in
combination, can cause heat build-up and pos-
sible tire failure.

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 systems
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 understand-
ing of the circumstances in which crashes and
injuries occur.NOTE: EDR data are recorded by your vehicle
only if a nontrivial crash situation occurs; no
data are recorded by the EDR under normal
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 investigation.
To read data recorded by an EDR, special equip-
ment is required and access to the vehicle or
the EDR is needed. In addition to the vehicle
manufacturer and INFINITI retailer, other par-
ties, such as law enforcement, that have the
special equipment, can read the information 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.Genuine INFINITI Service Manuals for this model
year and prior can be purchased. A Genuine
INFINITI Service Manual is the best source of
service and repair information for your vehicle.
This manual is the same one used by the factory
trained technicians working at INFINITI retailers.
Genuine INFINITI Owner’s Manuals can also be
purchased.
