actual fuel consumption.
The display is updated every 30 seconds.
The dte mode includes a low range warning
feature. If the fuel level is low, the warning
is displayed on the screen.
When the fuel level drops even lower, the
dte display will change to“——”.
. If the amount of fuel added is small, the
display just before the ignition switch
is pushed to the OFF position may
continue to be displayed.
. When driving uphill or rounding curves,
the fuel in the tank shifts, which may
momentarily change the display.
5. Outside air temperature (ICY —8F
or 8C)
The outside air temperature is displayed in
8For 8C in the range of −22 to 1318F(−30
to 558C).
The outside air temperature mode includes
a low temperature warning feature. If the
outside air temperature is below 378 F
(38C), the warning is displayed on the
screen.
The outside temperature sensor is located
in front of the radiator. The sensor may be affected by road or engine heat, wind
directions and other driving conditions.
The display may differ from the actual
outside temperature or the temperature
displayed on various signs or billboards.

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.
SIC2768
The sunload sensor*Aon the instrument
panel helps maintain a constant tempera-
ture. Do not put anything on or around this
sensor.
IN-CABIN MICROFILTER
Type A and B:
The climate control system is equipped
with an in-cabin microfilter which collects
dirt, pollen, dust, etc. To make sure the air
conditioner heats, defogs, and ventilates
efficiently, replace the filter in accordance
with the maintenance schedule in the
INFINITI Service and Maintenance Guide.
To replace the filter, contact an INFINITI retailer.
The filter should be replaced if air flow is
extremely decreased or when windows fog
up easily when operating heater or air
conditioning system.
Type C:
The climate control system is equipped
with a natural grape seed polyphenol filter
which collects and neutralizes dirt, pollen,
dust, etc. To make sure that the air
conditioner heats, defogs and ventilates
efficiently, replace the filter in accordance
with the maintenance schedule in the
INFINITI Service and Maintenance Guide.
To replace the filter, contact an INFINITI
retailer.
The filter should be replaced if the air flow
decreases significantly or if windows fog
up easily when operating the heater or air
conditioner.

Remove the retainers*1as illustrated and
pull out the filter element
*2.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See “INFINITI Ser-
vice and Maintenance Guide” for mainte-
nance intervals. When replacing the filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNING
.
Operating the engine with the air
cleaner removed can cause you or others
to be burned. The air cleaner not only
cleans the air, it stops flame if the
engine backfires. If it isn’t there, and the
engine backfires, you could be burned.
Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.
. Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.

Technical and consumer information9-3

Oil which may contain foreign matter or
has been previously used should not be
used.
Oil viscosity
The engine oil viscosity or thickness
changes with temperature. Because of this,
it is important that the engine oil viscosity
be selected based on the temperatures at
which the vehicle will be operated before
the next oil change. Choosing an oil
viscosity other than that recommended
could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When
replacing, use the genuine 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. Oil and
filter other than the specified quality, or oil
and filter change intervals longer than
recommended could reduce engine life.
Damage to engines caused by improper
maintenance or use of incorrect oil andfilter quality and/or viscosity is not covered
by the new INFINITI vehicle limited warran-
ties.
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 Main-
tenance Guide” for the maintenance sche-
dule.AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT RE-
COMMENDATIONS
The air conditioning system in your
INFINITI vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN A/C system oil Type S
or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant
will cause severe damage to the air con-
ditioning system and will require the repla-
cement 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 re-
covery and recycling of any refrigerant
during automotive air conditioning system
service. Your INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.
Contact an INFINITI retailer when servicing
your air conditioning system.
