frame, tie rods)
• Differential and fluid (AWD models)
• Battery terminals and cables, battery test
• Tire pressure, treadwear and depth
Essentials:
• Replace engine oil & filter (2)
• Replace engine air filter (3)

Severe use maintenance:
Inspections:
• Brake pads & rotors
• Exhaust system
• Propeller shaft (AWD models)
• Drive shaft boots
• Steering gear & linkage
• Axle & suspension parts
Essentials:
• Replace brake fluid (1) If towing a trailer, using a camper or a
car-top carrier, or driving on rough or muddy
roads, change (not just inspect) oil every
20,000 miles (32,000 km) or 24 months.
(2) If the oil replacement indicator is dis-
played, change the engine oil and filter within
two weeks or less than 500 miles (800 km).
(3) If operating mainly in dusty conditions,
more frequent maintenance may be required.
* Maintenance items and intervals with“*”
are recommended by INFINITI for reliable
vehicle operation. The owner need not per-
form such maintenance in order to maintain
the emission warranty or manufacturer recall
liability. Other maintenance items and inter-
vals are required.

Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant to select the engine oil viscosity based on
the temperatures at which the vehicle will be
operated before the next oil change. Choos-
ing an oil viscosity other than that recom-
mended could cause serious engine damage.
Selecting the correct oil filter
Your new INFINITI vehicle is equipped with a
high-quality Genuine NISSAN oil filter. When
replacing, use a Genuine NISSAN 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. Using engine oil and
filters that are not of the specified quality, or
exceeding recommended oil and filter change
intervals could reduce engine life.
CAUTION
Damage to engine caused by improper main-
tenance or use of incorrect oil and filter qual-
ity and/or viscosity is not covered by the
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 recom-
mended 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 out-side temperatures
• driving in dusty conditions
• extensive idling
• towing a trailer
• stop and go commuting
For additional information on maintenance
schedules, see “Maintenance and schedules”
(P. 9-2).
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFO-1234yf (R-1234yf) and the oil,
Genuine NISSAN A/C System Oil Type PAG
(ND-OIL12) or the exact equivalents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.
The refrigerant HFO-1234yf (R-1234yf) in
your INFINITI vehicle does not harm the
earth's ozone layer. Although this refrigerant
does not affect the earth's atmosphere, cer-
tain government regulations require the re-
covery and recycling of any refrigerant during
automotive air conditioner system service. Air
conditioner system should only be serviced by
trained and certified technicians to ensure
proper and safe operation (SAE J2845). An
INFINITI retailer has the trained technicians
and equipment needed to recover and recycle
your air conditioner system refrigerant. Only
new and SAEJ2842 certified evaporator(s)
shall be used as replacement parts.
A damaged or leaking air conditioning evapo-
rator shall never be repaired or replaced with
one removed from a used or salvaged vehicle.
To replace a damaged or leaking evaporator,
use only new and SAE J2842 certified
evaporator(s). It is recommended that you
visit an INFINITI retailer when servicing your
air conditioner system.
