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 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 broad-
casting station.
• When in possession of wireless equip- ment, such as a cellular telephone, trans-
ceiver 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 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 (
) will
show on the vehicle information display af-
ter the ignition switch is placed in the ON
position.
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.
