odors such as pulp or chemicals and
exhaust gas such as gasoline or diesel.
When the automatic intake air control is
ON, for the first 5 minutes, the recircula-
tion mode is selected to prevent dust, dirt
and pollen from entering the vehicle and
cleans the air inside of the vehicle with
Plasmacluster
®ion that are emitted from
the ventilator.
After 5 minutes, the sensor detects outside
odors and exhaust gas and automatically
alternates between the recirculation mode
and outside air circulation mode.
OPERATING TIPS
When the engine coolant temperature and
outside air temperature are low, the air
flow from the foot outlets may not operate
for a maximum of 150 seconds. This is not
a malfunction. After the coolant tempera-
ture warms up, air will flow normally from
the foot outlets.

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” (P.9-2). INFINITI recommends
the use of an energy conserving 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.
