WARNING
∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
∙ The remote keyless entry key fob transmits radio waves when the but-
tons are pressed. The FAA advises ra-
dio waves may affect aircraf t naviga-
tion and communication systems. Do
not operate the remote keyless entry
key fob while on an airplane. Make
sure the buttons are not operated un-
intentionally when the unit is stored
for a flight.
It is possible to lock/unlock all doors, turn
the interior lights on, and activate the panic
alarm by using the key fob from outside the
vehicle.
Be sure to remove the key from the ve-
hicle before locking the doors.
The key fob can operate at a distance of
approximately 33 f t (10 m) from the vehicle.
The effective distance depends on the
conditions around the vehicle. As many as four key fobs can be used with
one vehicle. For information concerning
the purchase and use of additional key
fobs, it is recommended that you visit a
NISSAN dealer.
The key fob will not function when:
∙ The battery is discharged.
∙ The distance between the vehicle and the key fob is over 33 f t (10 m).
The panic alarm will not activate when
the key is in the ignition switch.
CAUTION
Listed below are conditions or occur-
rences which will damage the key fob:
∙ Do not allow the key fob, which con- tains electrical components, to come
into contact with water or salt water.
This could affect the system function.
∙ Do not drop the key fob.
∙ Do not strike the key fob sharply against another object.
∙ Do not change or modif y the key fob.
∙ Wetting may damage the key fob. If the key fob gets wet, immediately
wipe until it is completely dry. ∙ Do not place the key fob for an ex-
tended period in an area where tem-
peratures exceed 140°F (60°C).
∙ Do not attach the key fob with a key holder that contains a magnet.
∙ Do not place the key fob near equip- ment that produces a magnetic field,
such as a TV, audio equipment and
personal computers.
If a key fob is lost or stolen, NISSAN rec-
ommends erasing the ID code of that

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 system trans-
mits weak radio waves. Environmental
conditions may interfere with the opera-
tion 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
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, the
Intelligent Key system warning light (
)
will blink green for about 30 seconds af ter
the ignition switch is placed in the ON po-
sition.
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 information regarding replacement of
a battery, 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.
