Pre-driving checks and adjustments3-3

WARNING
.Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use.
. The Intelligent Key transmits radio
waves when the buttons are pushed.
The FAA advises that 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 during a
flight.
The Intelligent Key system can operate all
the door locks using the remote controller
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 system 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
vehicle 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,
transceiver, and 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 func-
tion or use the mechanical key.
Although the life of the battery varies
depending on the operating conditions, the
battery’s life is approximately 2 years. If the
battery is discharged, replace it with a new
one.
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and
personal computer, the battery life may
become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replace-
ment” (P.8-21).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, contact an
INFINITI retailer.
CAUTION
. Do not allow the Intelligent Key,
which contains electrical compo-
nents, 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 Intelli-
gent Key.
. Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet,
immediately wipe until it is comple-
tely dry.
. If the outside temperature is below
14°F (−10°C), the battery of the
Intelligent Key may not function
properly.
. Do not place the Intelligent Key for
an extended period in an area where
temperatures 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
Intelligent Key from the vehicle. This may
prevent the unauthorized use of the Intelli- gent Key to operate the vehicle. For infor-
mation regarding the erasing procedure, it is
recommended that you contact an INFINITI
retailer.
