INFINITI INTELLIGENT KEY
Your vehicle can only be driven with the Intel-
ligent Keys which are registered to your vehi-
cle’s Intelligent Key System components and
INFINITI Vehicle Immobilizer System
components.Never leave the keys in the vehicle.
As many as four Intelligent Keys can be reg-
istered and used with one vehicle. The new
keys must be registered prior to use with the
Intelligent Key System and INFINITI Vehicle
Immobilizer System of your vehicle. It is rec-
ommended that you visit an INFINITI retailer
for this service. Since the registration process
requires erasing all memory in the Intelligent
Key components when registering new keys,
be sure to take all Intelligent Keys that you
have to an INFINITI retailer.A key number plate is supplied with your keys.
Record the key number and keep it in a safe
place (such as your wallet), not in the vehicle.
If you lose your keys, it is recommended that
you visit an INFINITI retailer for duplicates by
using the key number. INFINITI does not re-
cord key numbers so it is very important to
keep track of your key number plate.
A key number is only necessary when you
have lost all keys and do not have one to
duplicate from. If you still have a key, it can be
duplicated without knowing the key number.
CAUTION
Be sure to carry the Intelligent Key with
you when driving. The Intelligent Key is a
precision device with a built-in transmit-
ter. To avoid damaging it, please note the
following:
– The Intelligent Key is water resistant;
however, wetting may damage the In-
telligent Key. If the Intelligent Key gets
wet, immediately wipe until it is com-
pletely 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.LPD2848

3-2Pre-driving checks and adjustments

•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 broadcast-
ing station.
• When in possession of wireless equipment, such as a cellular telephone, transceiver or
a CB radio.
• When the Intelligent Key is in contact with or covered by metallic materials.
• When any type of radio wave remote con- trol 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, see “Vehicle information display
warnings and indicators” (P. 2-21).
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, see “Battery re-
placement” (P. 8-22).
CAUTION
Listed below are conditions or occurrences
which will damage the Intelligent Key:
• Do not allow the Intelligent Key, which
contains electrical components, to come
into contact with water or salt water.
This could affect the system function.
• Do not drop the Intelligent Key.
Pre-driving checks and adjustments3-7

•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, im-
mediately 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.
OPERATING RANGE
The Intelligent Key functions can only be used
when the Intelligent Key is within the speci-
fied operating range from the door handle
request switch or the one touch unlock sen-
sor
O1. When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key operating range becomes narrower, and
the Intelligent Key may not function properly.
The operating range is within 31.5 in (80 cm)
from each request switch or one touch unlock
sensor
O1.
If the Intelligent Key is too close to the door
glass, handle or rear bumper, the request
switches or the one touch unlock sensor may
not function.
If any of the front doors are recently closed
and locked, you must wait 2 seconds before
you can unlock the door with the one touch
unlock sensor. Pulling the handle within 2
seconds of locking the door will allow you
time to confirm that the door has been locked
without accidentally unlocking the door with
the one touch unlock sensor.
If you pull the door handle with your gloved
hand, the one touch unlock sensor operation
may not function.
When the Intelligent Key is within the operat-
ing range, it is possible for anyone, even
someone who does not carry the Intelligent
Key, to push the request switch or the one
touch unlock sensor to lock/unlock the door
within range.
