4. Distance to empty (dte — MILES 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

OPERATING TIPS
When the engine coolant temperature and out-
side air temperature are low, the air flow from
the foot outlets may not operate. However, this
is not a malfunction. After the coolant tempera-
ture warms up, the air flow from the foot outlets
will operate normally.
The sensors
AandBlocated on the instru-
ment panel help maintain a constant tempera-
ture. Do not put anything on or around the
sensors.
IN-CABIN MICROFILTER
Models without Advanced Climate Control Sys-
tem:
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. Models with Advanced Climate Control System:
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.SAA3088

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. 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.
● On gasoline engine models, the fuel filter or
fuel lines should be serviced by an INFINITI
retailer because the fuel lines are under high
pressure even when the engine 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.
This “8. Maintenance and do-it-yourself” sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able. (See “OWNER’S MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9. Tech-
nical and consumer information” section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, we recommend that it be done by an
INFINITI retailer.
MAINTENANCE PRECAUTIONS
Maintenance and do-it-yourself8-5

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.To remove the filter, release the lock pins
1
and pull the unit upward2.
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.
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.
