NOTE:
(1) After 30,000 miles (48,000 km) or 48 months, inspect every 7,500 miles (12,000 km) or 12 months. Replace the drive belts if found
damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Periodic maintenance is not required.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles
(120,000 km) or 60 months.
(5) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% antifreeze and 50%
demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water may reduce the life expectancy of the
factory fill coolant.
(6) If the oil replacement indicator is displayed, change the engine oil and filter within two weeks or less than 500 miles (800 km)
(7) Replace spark plug when the plug gap exceeds 0.045 in (1.15 mm) even if within specified periodic replacement mileage.
(8) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform such
maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are required.

10-2Technical and consumer information

CAUTION
Damage to engine caused by improper
maintenance or use of incorrect oil and fil-
ter quality 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 ve-
hicle.
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
∙ towing a trailer
∙ stop and go commuting
For additional information on maintenance
schedules, refer to the “Maintenance and
schedules” section of this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFC-134a (R-134a) and the oil, Genuine
NISSAN A/C System Oil Type ND-OIL8 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 HFC-134a (R-134a) in your
INFINITI vehicle does not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
government regulations require the recovery
and recycling of any refrigerant during auto-
motive 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
system.
