Instruments and controls2-27

WARNING
∙ Radio waves could adversely affect elec-tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
∙ The Intelligent Key transmits radio waves when the buttons are pressed. The
FAA advises the radio waves may affect
aircraft navigation and communication
systems. Do not operate the Intelligent
Key while on an airplane. Make sure the
buttons are not operated unintentionally
when the unit is stored for a flight.
The Intelligent Key system can operate all the
door locks using the remote control function
or pushing the request switch on the vehicle
without taking the key out from a pocket or
purse. The operating environment and/or
conditions may affect the Intelligent Key sys-
tem operation.
Be sure to read the following before using the
Intelligent Key system.
CAUTION
∙ Be sure to carry the Intelligent Key with you when operating the vehicle. ∙ Never leave the Intelligent Key in the ve-
hicle when you leave the vehicle.
The Intelligent Key is always communicating
with the vehicle as it receives radio waves.
The Intelligent Key system transmits weak
radio waves. Environmental conditions may
interfere with the operation of the Intelligent
Key system under the following operating
conditions: ∙ When operating near a location where strong radio waves are transmitted, such
as a TV tower, power station and broad-
casting station.
∙ When in possession of wireless equip- ment, such as a cellular telephone, trans-
ceiver or a CB radio.
∙ When the Intelligent Key is in contact with or covered by metallic materials.
∙ When any type of radio wave remote control is used nearby.
∙ When the Intelligent Key is placed near an electric appliance such as a personal
computer.
∙ When the vehicle is parked near a parking meter. In such cases, correct the operating condi-
tions before using the Intelligent Key function
or use the mechanical key.
Although the life of the battery varies de-
pending on the operating conditions, the bat-
tery’s life is approximately two years. If the
battery is discharged, replace it with a new
one.
When the Intelligent Key battery is low, an
indicator illuminates in the vehicle informa-
tion display. For additional information, refer
to “Vehicle information display” in the “Instru-
ments and controls” section of this manual.
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may become
shorter.
For additional information, refer to “Battery
replacement” in the “Do-it-yourself” section
of this manual.
As many as four Intelligent Keys can be reg-
istered and used with one vehicle. For infor-
mation about the purchase and use of addi-
tional Intelligent Keys, it is recommended that
you visit an INFINITI retailer.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
∙ Park the vehicle on a level surface, applythe parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Move the shift lever to P (Park).
∙ Be sure the ignition switch is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ 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 work-
ing on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position and
the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
∙ 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 supported 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 the fuel tank and
battery.
∙ Because the fuel lines on gasoline engine models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
∙ Do not work under the hood while theengine is hot. Turn the engine off and
wait until it cools down. ∙ Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
∙ Never leave the engine or Continuously Variable Transmission (CVT) related
component harnesses disconnected
while the ignition switch is in the ON
position.
∙ Never connect or disconnect the battery or any transistorized component while
the ignition switch is in the ON position.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, refer to
“Owner’s Manual/Service Manual order in-
formation” in the “Technical and consumer
information” section of this manual.

culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.
