— The Intelligent Key is water re-sistant; however, wetting may
damage the Intelligent Key. If the
Intelligent Key gets wet, immedi-
ately wipe until it is completely
dry.
— Do not bend, drop or strike it against another object.
— 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 a place
where temperatures exceed
140°F (60°C).
— Do not change or modify the Intelligent Key.
— Do not use a magnet key holder.
— Do not place the Intelligent Key near an electric appliance such as
a television set or personal com-
puter.
— Do not allow the Intelligent Key to come into contact with water
or salt water, and do not wash it

affect the system function. .
If an Intelligent Key is lost or stolen,
INFINITI recommends erasing the ID
code of that Intelligent Key. This will
prevent the Intelligent Key from un-
authorized use to unlock the vehicle.
For information regarding the eras-
ing procedure, it is recommended you
visit an INFINITI retailer.

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 doors and the trunk lid using the remote
controller function, using one touch unlock
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.
When the Intelligent Key battery is almost
discharged, see “Intelligent Key battery dis-
charge” (P.5-14) to start the engine.
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.8-26).
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.
