AMBIENT TEMPERATURE The outside ambient temperature will be
shown on the center display.
The ambient temperature sensor is located in
front of the radiator. The sensor may be af-
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.

WARNINGO Do not leave children, impaired
adults, or pets alone in your vehicle.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
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.
EXHAUST GAS (Carbon monoxide)
WARNINGDo not breathe exhaust gases; they con- tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous. It
can cause unconsciousness or death.
O If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.
O Do not run the engine in closed
spaces such as a garage.
O Do not park the vehicle with the en-
gine running for any extended length
of time.
O Keep the trunk lid closed while driv-
ing, otherwise exhaust gases could
be drawn into the passenger com-
partment. If you must drive with the
trunk lid open, follow these precau-
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
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes
are entering into the passenger
compartment.
c. You notice a change in the sound
of the exhaust system.PRECAUTIONS WHEN STARTING
AND DRIVING

d. You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
THREE WAY CATALYST The three way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the converter are burned at
high temperatures to help reduce pollutants.
WARNINGO The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system compo-
nents.
O Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire. CAUTION O Do not use leaded gasoline. Deposits
from leaded gasoline seriously re-
duce the three way catalyst's ability
to help reduce exhaust pollutants.
O Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over-
rich fuel flow into the three way cata-
lyst, causing it to overheat. Do not
keep driving if the engine misfires, or
if noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by an authorized
INFINITI retailer.
O Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.
O Do not race the engine while warming
it up.
O Do not push or tow your vehicle to
start the engine. AVOIDING COLLISION AND
ROLLOVER
WARNING Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden steer-
ing maneuvers, because these driving prac-
tices could cause you to lose control of your
vehicle. As with any vehicle, a loss of con-
trol could result in a collision with other
vehicles or objects, or cause the vehicle to
rollover, particularly if the loss of control
causes the vehicle to slide sideways. Be
attentive at all times, and avoid driving when
tired. Never drive when under the influence of
alcohol or drugs (including prescription or
over-the-counter drugs which may cause
drowsiness). Always wear your seat belt. See
ªSeat Beltsº in the ª1. Seats, restraints and
supplemental air bag systemsº section. Also
instruct your passengers to do so.

INFINITI VEHICLE IMMOBILIZER
SYSTEM The Infiniti Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered Infiniti Vehicle Immobilizer System
key.
If the engine fails to start using the registered
Infiniti Vehicle Immobilizer System key, it may
be due to interference caused by another
Infiniti Vehicle Immobilizer System key, an
automated toll road device or automated pay-
ment device on the key ring. Restart the en-
gine using the following procedures: 1. Leave the ignition switch in the ON position
for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK
position and wait approximately 10 sec-
onds.
3. Repeat step 1 and 2 again.
4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered Infiniti Vehicle
Immobilizer System key.
If this procedure allows the engine to start,
INFINITI recommends placing the registered
Infiniti Vehicle Immobilizer System key on a
separate key ring to avoid interference from
other devices.
