CAUTION
∙ Be sure to carry the Intelligent Keywith you when operating the vehicle.
∙ Never leave the Intelligent Key in the vehicle when you leave the vehicle.
The Intelligent Key is always communicat-
ing with the vehicle as it receives radio
waves. The Intelligent Key transmits weak
radio waves. Environmental conditions
may interfere with the operation of the In-
telligent Key under the following operating
conditions: ∙ When operating near a location where strong radio waves are transmitted,
such as a TV tower, power station and
broadcasting station.
∙ When in possession of wireless equip- ment, 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 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 park-
ing 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 de-
pending on the operating conditions, the
battery’s life is approximately two years. If
the battery is discharged, replace it with a
new one.
When the Intelligent Key battery is low, an
indicator illuminates in the vehicle informa-
tion display. For additional information, re-
fer to “Vehicle information display” in the
“Instruments and controls” section of this
manual.
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is lef t near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may be-
come shorter.
For additional information, refer to “Battery
replacement” in the “Do-it-yourself ” section
of this manual. As many as four Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, it is recom-
mended that you visit a NISSAN dealer.

∙ Do not attach the Intelligent Key witha 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, NISSAN
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 visit a NISSAN
dealer.
OPERATING RANGE
The Intelligent Key functions can only be
used when the Intelligent Key is within the
specified operating range from the request
switch
1. When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key system’s operating range becomes
narrower, and the Intelligent Key may not
function properly.
The operating range is within 31.50 in
(80 cm) from each request switch
1.
If the Intelligent Key is too close to the door
glass, handle or rear bumper, the request
switches may not function.
When the Intelligent Key is within the oper-
ating range, it is possible for anyone, even
someone who does not carry the Intelli-
gent Key, to push the request switch to
lock/unlock the doors.

Lockout protection
To prevent the Intelligent Key from being
accidentally locked in the trunk, lockout
protection is equipped with the Intelligent

is closed with the Intelligent Key inside the
trunk, the outside buzzer will sound and the
trunk will open.

erate all door locks using the remote key-
less function of the Intelligent Key. The re-
mote keyless function can operate at a
distance of 33 f t (10 m) away from the ve-
hicle. The operating distance depends
upon the conditions around the vehicle.
The remote keyless entry function may not
function under the following conditions:∙ When the Intelligent Key is not within the operational range.
∙ When the doors or the trunk are open or not closed securely.
∙ When the Intelligent Key battery is dis- charged.

OPERATING RANGE
The Intelligent Key functions can only be
used when the Intelligent Key is within the
