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.
∙
Before leaving the vehicle, engage the P
(Park) position and check that the elec-
tronic parking brake warning light is illumi-
nated to confirm that the electronic park-
ing brake is applied. The electronic parking
brake warning light will remain on for a pe-
riod of time after the driver’s door is locked.
∙ Make sure to engage the P (Park) posi- tion and apply the parking brake when
parking your vehicle, riding on or off the
vehicle or loading luggage. Failure to do
so could cause the vehicle to move or roll
away unexpectedly and result in serious
personal injury or property damage. 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, a
“Key Battery Low” indicator illuminates in the
vehicle information display. For additional in-
formation, refer to “Vehicle information dis-
play warnings and indicators” in the “Instru-
ments and controls” section of this manual.
INFINITI INTELLIGENT KEY SYSTEM
Pre-driving checks and adjustments3-7

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.
CAUTION
Listed below are conditions or occurrences
which will damage the Intelligent Key:
∙ Do not allow the Intelligent Key, whichcontains electrical components, to come
into contact with water or salt water.
This could affect the system function.
∙ Do not drop the Intelligent Key.
∙ Do not strike the Intelligent Key sharply against another object.
∙ Do not change or modify the Intelligent Key.
∙ Wetting may damage the Intelligent Key. If the Intelligent Key gets wet, immedi-
ately wipe until it is completely dry. ∙ Do not place the Intelligent Key for an
extended period in an area where tem-
peratures exceed 140°F (60°C).
∙ Do not attach the Intelligent Key with a key holder that contains a magnet.
∙ Do not place the Intelligent Key near equipment that produces a magnetic
field, such as a TV, audio equipment and
personal computers.
If an Intelligent Key is lost or stolen, INFINITI
recommends erasing the ID code of that In-
telligent Key from the vehicle. This may pre-
vent the unauthorized use of the Intelligent
Key to operate the vehicle. For information
regarding the erasing procedure, it is recom-
mended that you visit an INFINITI retailer.
