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 communicating with
the vehicle as it receives radio waves. The Intel-
ligent Key transmits weak radio waves. Environ-
mental conditions may interfere with the opera-
tion of the Intelligent Key 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 equipment,
such as a cellular telephone, transceiver,
and 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 com-
puter. ●
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 dis-
charged, insert the Intelligent Key into the Intelli-
gent Key port to start the engine. Replace the
discharged battery with a new one as soon as
possible. For more details, see “Push-button ig-
nition switch” in the “Starting and driving” sec-
tion.
Since the Intelligent Key is continuously receiving
radio waves, if the key is left near equipment
which transmits strong radio waves, such as sig-
nals from a TV and personal computer, the bat-
tery life may become shorter.
For information regarding replacement of a bat-
tery, see “Battery replacement” in the “Mainte-
nance and do-it-yourself” section.
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 dealer.

If an Intelligent Key is lost or stolen, NISSAN
recommends erasing the ID code of that Intelli-
gent Key from the vehicle. This may prevent the
unauthorized use of the Intelligent Key to operate
the vehicle. For information regarding the erasing
procedure, contact a NISSAN dealer.
OPERATING RANGE
The Intelligent Key functions can only be used
when the Intelligent Key is within the specified
operating range from the request switch
1.When the Intelligent Key battery is discharged or
strong radio waves are present near the operat-
ing location, the Intelligent Key system’s operat-
ing range becomes narrower, and the Intelligent
Key may not function properly.
The operating range is within 31.50 in (80 cm)
from each request switch
1.
If the Intelligent Key is too close to the door glass,
handle or rear bumper, the request switches may
not function.
When the Intelligent Key is within the operating
range, it is possible for anyone, even someone
who does not carry the Intelligent Key, to push the
request switch to lock/unlock the doors.

The interior light timer illuminates for 30 seconds
when a door is unlocked and the room light
switch is in the DOOR position.
The interior light can be turned off without waiting
for 30 seconds by performing one of the follow-
ing operations.● Placing the ignition switch in the ON posi-
tion.
● Locking the doors with the remote controller.

more than 1 second while carrying the Intel-
ligent Key with you.
2. The trunk will unlatch. A chime will sound 4 times.
3. Raise the trunk lid to open the trunk.
Lockout protection
To prevent the Intelligent Key from being acci-
dentally locked in the trunk, lockout protection is
equipped with the Intelligent Key. When all doors are locked and the trunk lid is
closed with the Intelligent Key inside the trunk,
the outside buzzer will sound and the trunk will
open.
HOW TO USE THE REMOTE
KEYLESS ENTRY FUNCTION
The remote keyless entry function can operate all
door locks using the remote keyless function of
the Intelligent Key. The remote keyless function
