4. When closing the hood, reset the assist bar
to its original position, then slowly close the
hood and make sure it locks into place.
WARNING O Make sure the hood is completely
closed and latched before driving.
Failure to do so could cause the hood
to fly open and result in an accident.
O If you see steam or smoke coming
from the engine compartment, to
avoid injury do not open the hood. WARNING O Do not drive with the trunk lid open.
This could allow dangerous exhaust
gases to be drawn into the vehicle.
See ªPrecautions when starting and
drivingº in the ª5. Starting and driv-
ingº section for exhaust gas.
O Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked with the
trunk closed when not in use, and
prevent children's access to car keys. SPA1423

ously injured if it is misused or mis-
handled. Always stop the engine and
do not smoke or allow open flames or
sparks near the vehicle when refuel-
ing.
O Fuel may be under pressure. Turn the
cap a quarter turn, and wait for any
hissing sound to stop to prevent fuel
from spraying out and possible per-
sonal injury. Then remove the cap.
O Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off
automatically.
Continued refueling may cause fuel
overflow, resulting in fuel spray and
possibly a fire.
O Use only an original equipment type
fuel filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious
malfunction and possible injury. It
could also cause the malfunc-
tion indicator lamp to come on.
O Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
Ð Always place the container on the
ground when filling.
Ð Do not use electronic devices
while filling.
Ð Keep the pump nozzle in contact
with the container while you are
filling it. Ð Use only approved portable fuel
containers for flammable liquid.
O Never pour fuel into the throttle body
to attempt to start your vehicle.
CAUTION O If fuel is spilled on the car body, flush
it away with water to avoid paint dam-
age.
O Tighten until the fuel filler cap clicks.
Failure to tighten the fuel filler cap
properly may cause the
mal-
function indicator lamp (MIL) to illu-
minate. If the
lamp illuminates
because the fuel filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
lamp should turn off after a few
driving trips. If the
lamp does
not turn off after a few driving trips,
have the vehicle inspected by an au-
thorized INFINITI retailer.SPA1563

fected by road or engine heat, wind direction
and other driving conditions. The display may
differ from the actual outside temperature or
the temperature displayed on various signs or
billboards.
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. However, this is not
a malfunction. After the coolant temperature
warms up, the air flow from the foot outlets will
operate normally. The sensor on the instrument panel helps
maintain a constant temperature; do not put
anything on or around this sensor.
IN-CABIN MICROFILTER The air conditioning system is equipped with a
in-cabin microfilter which collects dirt, pollen,
dust, etc. To make sure air conditioner heats,
defogs, and ventilates efficiently, replace the
filter in accordance with the maintenance
schedule in this manual. To replace the filter,
contact your INFINITI retailer.
The filter should be replaced if air flow
decreases significantly or if windows fog HA1011

up easily when operating the heater or air
conditioning system. The air conditioning system in your INFINITI
vehicle is charged with a refrigerant designed
with the environment in mind. This refrigerant
will not harm the earth's ozone layer. How-
ever, special charging equipment and lubricant
are required when servicing your NISSAN air
conditioner. Using improper refrigerants or lu-
bricants will cause severe damage to your air
conditioning system. See ªCapacities and rec-
ommended fuel/lubricantsº in the ª10. Techni-
cal and consumer informationº section for air
conditioning system refrigerant and lubricant
recommendations.
Your INFINITI retailer will be able to service
your environmentally friendly air conditioning
system.
WARNING The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper equip-
ment. Turn the ignition key to ACC or ON and press
the POWER, FM or AM button to turn on the
radio. If you listen to the radio with the engine
not running, the key should be turned to the
ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external
influences. Intermittent changes in reception
quality normally are caused by these external
influences.
Using a cellular phone in or near the ve-
hicle may influence radio reception quality.
Radio reception Your radio system is equipped with state-of-
the-art electronic circuits to enhance radio
reception. These circuits are designed to ex-
tend reception range, and to enhance the
quality of that reception.
However there are some general characteris-
tics of FM, AM and satellite radio signals that
can affect radio reception quality in a moving
vehicle, even when the finest equipment is
used. These characteristics are completely
normal in a given reception area, and do not
indicate any malfunction in your radio system.
Remember that a moving vehicle is not the
ideal place to listen to a radio. Because of theSERVICING AIR CONDITIONER AUDIO SYSTEM

Satellite radio antenna Satellite radio performance may be affected if
cargo carried on the roof rack blocks the
satellite radio signal. If possible, do not put
cargo over the satellite radio antenna. When installing a CB, ham radio or car phone
in your INFINITI, be sure to observe the fol-
lowing cautions, otherwise the new equipment
may adversely affect the Engine control sys-
tem and other electronic parts.
WARNING O A cellular telephone should not be
used while driving so full attention
may be given to vehicle operation.
Some jurisdictions prohibit the use of
cellular telephones while driving.
O If you must make a call while your
vehicle is in motion, the hands free
cellular phone operational mode (if
so equipped) is highly recommended.
Exercise extreme caution at all times
so full attention may be given to ve-
hicle operation.
O If a conversation in a moving vehicle
requires you to take notes, pull off the
road to a safe location and stop your
vehicle before doing so. CAUTION O Keep the antenna as far as possible
away from the Engine Control Module
(ECM).
O Keep the antenna wire more than 8 in
(20 cm) away from the Multiport Fuel
Injection harness. Do not route the
antenna wire next to any harness.
O Adjust the antenna standing-wave ra-
tio as recommended by the manufac-
turer.
O Connect the ground wire from the CB
radio chassis to the body.

tions:
1. Open all the windows.
2. Set the air recirculation switch
OFF and the fan control at 4 (high)
to circulate the air.
O If electrical wiring or other cable con- nections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle.
O If a special body or other equipment
is added for recreational or other us-
age, follow the manufacturer's rec-
ommendation to prevent carbon
monoxide entry into the vehicle.
(Some recreational vehicle appli-
ances such as stoves, refrigerator,
heaters, etc. may also generate car-
bon monoxide.)
O The exhaust system and body should
be inspected by a qualified mechanic
