CAUTION
.Be sure to carry the Intelligent Key
with you when operating the vehi-
cle.
. Never leave the Intelligent Key in
the vehicle when you leave the
vehicle.
The Intelligent Key is always communicating with
the vehicle because it receives radio waves. The
Intelligent Key system transmits weak radio
waves. Environmental conditions may interfere
with the operation 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 or broad-
casting station.
. When in possession of wireless equipment,
such as a cellular phone, transceiver or 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 parking
meter.
In such cases, correct the operating conditions
before using the Intelligent Key function or use
the mechanical key.
Although the life of the battery varies depending
on the operating conditions, the battery’s life is
approximately 2 years. If the battery is dis-
charged, replace it with a new one.
When the Intelligent Key battery is almost
discharged, firmly apply the foot brake and
touch the power switch with the Intelligent Key.
Then push the power switch while depressing
the brake pedal within 10 seconds after the
chime sound.
Since the Intelligent Key is continuously receiv-
ing radio waves, if the key is left near equipment
that transmits strong radio waves, such as
signals from a TV or personal computer, the
battery life may become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replacement”
in the “8. Maintenance and do-it-yourself”
section. Pay special attention that the vehicle battery is
not completely discharged.
As many as 4 Intelligent Keys can be registered
and used with one vehicle. For information about
the purchase and use of additional Intelligent
Keys, contact a NISSAN certified LEAF dealer.
