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.
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, see “Battery replacement”
(P. 8-23).
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:
• Do not allow the Intelligent Key,
which contains electrical compo-
nents, to come into contact with wa-
ter or salt water. This could affect the
system function.
• Do not drop the Intelligent Key.
• Do not strike the Intelligent Key
sharply against another object.
• Do not change or modif y the Intelli-
gent Key.
• Wetting may damage the Intelligent

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.
