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.
CAUTION
Listed below are conditions or occur-
rences which will damage the Intelli-
gent Key:
