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
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.

*1: 18-in tire models
*2: 19-in tire models 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.
