4. Distance to empty (dte — mls or
km)
The distance to empty (dte) mode provides you
with an estimation of the distance that can be
driven before refueling. The dte is constantly
being calculated, based on the amount of fuel
in the fuel tank and the actual fuel consump-
tion.
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 momen-
tarily change the display.
5. Outside air temperature (ICY — °F
or °C)
The outside air temperature is displayed in °F or
°C in the range of 22 to 131°F (30 to 55°C). The outside air temperature mode includes a
low temperature warning feature. If the outside
air temperature is below 37°F (3°C), 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 bill-
boards.
6. Setting
Setting cannot be made while driving. A mes-
sage “Setting can only be operated when
stopped” is also displayed on the dot matrix
crystal display.

Instruments and controls2-25

●The air flow control is not in the front
defogger mode (the indicator light on the
“
” front defogger button is turned off).
● The outside temperature is about 32°F (0°C)
or more.
● The outside odor and exhaust gas detection
sensor detects industrial odors such as pulp
or chemicals and exhaust gas such as gaso-
line or diesel.
When the automatic intake air control is ON, for
the first 5 minutes, the recirculation 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 alter-
nates between the recirculation mode and out-
side air circulation mode.
OPERATING TIPS
When the engine coolant temperature and out-
side 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 temperature warms up, air will flow
normally from the foot outlets. The sunload sensor
Aon the instrument panel
helps maintain a constant temperature. 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 Mainte-
nance Guide. To replace the filter, contact an
INFINITI retailer. The filter should be replaced if air flow is ex-
tremely decreased or when windows fog up eas-
ily when operating heater or air conditioning
system.
Type C:
The climate control system is equipped with a
natural grape seed polyphenol filter which col-
lects 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 de-
creases significantly or if windows fog up easily
when operating the heater or air conditioner.SERVICING CLIMATE CONTROL
The climate control system in your INFINITI is
charged with a refrigerant designed with the
environment in mind.
This refrigerant will not
harm the earth’s ozone layer. However, special
charging equipment and lubricant are required
when servicing your INFINITI air conditioner.
Using improper refrigerants or lubricants will
cause severe damage to your climate control
system. (See “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
●Park the vehicle on a level surface, apply the
parking brake securely and block the wheels
to prevent the vehicle from moving. For
manual transmission models, move the shift
lever to N (Neutral). For automatic transmis-
sion models, move the selector lever to P
(Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition switch is in the
ON position. ●
If you must work with the engine running,
keep your hands, clothing, hair and tools
away from moving fans, belts and any other
moving parts.
● It is advisable to secure or remove any loose
clothing and remove any jewelry, such as
rings, watches, etc. before working on your
vehicle.
● Always wear eye protection whenever you
work on your vehicle.
● If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
● Never get under the vehicle while it is sup-
ported only by a jack. If it is necessary to
work under the vehicle, support it with
safety stands.
● Keep smoking materials, flame and sparks
away from fuel tank and the battery. ●
Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
key is in the OFF position and the engine is
not running. To avoid injury, always discon-
nect the negative battery cable before work-
ing near the fan.
● The fuel filter or fuel lines should be serviced
by an INFINITI retailer because the fuel lines
are under high pressure even when the en-
gine is off.
CAUTION
● Do not work under the hood while the engine
is hot. Turn the engine off and wait until it
cools down.
● Avoid direct contact with used engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
MAINTENANCE PRECAUTIONS
Maintenance and do-it-yourself8-5

WARNING
Be sure the engine and the ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to remove the
spark plugs. An incorrect socket can damage
the spark plugs.
REPLACING SPARK PLUGS
If replacement is required, see an INFINITI re-
tailer for servicing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much
longer. Follow the maintenance schedule in
“INFINITI Service and Maintenance Guide”, but
do not reuse them by cleaning or regapping.
Always replace spark plugs with recommended
or equivalent ones.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 mainte-
nance intervals. See “INFINITI Service and Main-
tenance Guide” for maintenance intervals.

SPARK PLUGS AIR CLEANER
8-18Maintenance and do-it-yourself

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 work-
ing on the engine with the air cleaner
removed.
● Never pour fuel into the throttle body or at-
tempt to start the engine with the air cleaner
removed. Doing so could result in serious
injury.
CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your wind-
shield is clean if beads do not form when
rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blade with clear water. If
your windshield is still not clear after cleaning
the blades and using the wiper, replace the
blades.
Worn windshield wiper blades can damage the
windshield and impair driver vision.

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.
