3-2Pre-driving checks and adjustments
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 recom-
mended you visit an INFINITI retailer for
duplicates by using the key number. INFINITI
does not record any 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.

INTELLIGENT KEY
Your vehicle can only be driven with the
Intelligent Keys which are registered to your
vehicle’s Intelligent Key system components
and INFINITI Vehicle Immobilizer System
components. As many as 4 Intelligent Keys
can be registered and used with one vehicle.
The new keys must be registered by an
INFINITI retailer prior to use with the
Intelligent Key system and INFINITI Vehicle
Immobilizer System of your vehicle. 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 the
INFINITI retailer.
CAUTION
. Be sure to carry the Intelligent Key
with you when driving. The Intelli-
gent Key is a precision device with a
built-in transmitter. To avoid dama-
ging it, please note the following.
— The Intelligent Key is water re- sistant; however, wetting may
KEYS

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
in a washing machine. This could
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

3-4Pre-driving checks and adjustments
VALET HAND-OFF
When you have to leave a key with a valet,
give them the Intelligent Key itself and keep
the mechanical key with you to protect your
belongings.
To prevent the glove box from being opened
during valet hand-off, follow the procedures
below.
1. Remove the mechanical key from theIntelligent Key.
2. Lock the glove box with the mechanical key.
3. Hand the Intelligent Key to the valet, keeping the mechanical key in your
pocket or bag for insertion into the
Intelligent Key when you retrieve your
vehicle.
See “Storage” (P.2-60).WARNING
. Always have the doors locked while
driving. Along with the use of seat
belts, this provides greater safety in
the event of an accident by helping to
prevent persons from being thrown
from the vehicle. This also helps keep
children and others from unintention-
ally opening the doors, and will help
keep out intruders.
. Before opening any door, always look
for and avoid oncoming traffic.
. To help avoid risk of injury or death
through unintended operation of the
vehicle and or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets
unattended in your vehicle. Addition-
ally, the temperature inside a closed
vehicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.

position with any door open, all doors will
lock and unlock automatically. With the
Intelligent Key left in the vehicle and any
door open, all doors will unlock automati-
cally and a chime will sound after the door is

These functions help to prevent the Intelli-
gent Key from being accidentally locked
inside the vehicle.

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

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.
