NOTE:
When programming a garage door opener,
etc., it is advised to unplug the device dur-
ing the “cycling” process to prevent pos-
sible damage to the garage door opener
components.
OPERATING THE HOMELINK
UNIVERSAL TRANSCEIVER
The HomeLinkUniversal Transceiver (once pro-
grammed) may now be used to activate the ga-
rage door, etc. To operate, simply press the ap-
propriate programmed HomeLink Universal
Transceiver button. The red indicator light will
illuminate while the signal is being transmitted.
PROGRAMMING TROUBLE-
DIAGNOSIS
If the HomeLink does not quickly learn the hand-
held transmitter information:
● replace the hand-held transmitter batteries
with new batteries.
● position the hand-held transmitter with its
battery area facing away from the
HomeLink surface.
● press and hold both the HomeLink and
hand-held transmitter buttons without inter-
ruption. ●
position the hand-held transmitter1-3
inches (26 - 76 mm) away from the
HomeLink surface. Hold the transmitter in
that position for up to 15 seconds. If
HomeLink is not programmed within that
time, try holding the transmitter in another
position – keeping the indicator light in view
at all times.
If you continue to have programming difficulties,
please contact the NISSAN Consumer Affairs
Department. The phone numbers are located in
the Foreword of this manual.
CLEARING THE PROGRAMMED
INFORMATION
Individual buttons cannot be cleared. However,
to clear all programming, press and hold the two
outside buttons and release when the indicator
light begins to flash (approximately 20 seconds) .
ROLLING CODE PROGRAMMING
Rolling code garage door openers (or other roll-
ing code devices) which are “code protected”
and manufactured after 1996, may be deter-
mined by the following: ● Reference the garage door opener Owner’s
Manual for verification. ●
The hand-held transmitter appears to pro-
gram the HomeLink Universal Transceiver
but does not activate the garage door.
● Press and hold the trained HomeLink but-
ton. If the garage door opener has the rolling
code feature, the HomeLink indicator light
will flash rapidly, then remain on after 2 sec-
onds.
To program the HomeLink Universal Transceiver
to a garage door opener with the rolling code
feature, follow these instructions after completing
the “Programming HomeLink” (the aid of a sec-
ond person may make the following procedures
quicker and easier) .
1. Locate the training button on the garage door opener motor unit. Exact location and
color of the button may vary by garage door
opener brand. If there is difficulty locating
the training button, reference the garage
door opener Owner’s Manual.
2. Press the training button on the garage door opener motor unit (which may activate a
training light) .

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.

CAUTION
Listed below are conditions or occur-
rences which will damage the Intelligent
Key:
●Do not allow the Intelligent Key, which
contains electrical components, to
come into contact with water 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 modify the Intelligent
Key.
● Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet, im-
mediately wipe until it is completely dry.
● Do not place the Intelligent Key for an
extended period in an area where tem-
peratures exceed 140°F (60°C) .
● Do not attach the Intelligent Key with a
key holder that contains a magnet.
● Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment and
personal computers. 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.
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 33 ft (10 m) of the
vehicle.
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
can operate at a distance of 33 ft (10 m) away
from the vehicle. The operating distance de-
pends upon the conditions around the vehicle.
The remote keyless entry function will not func-
tion under the following conditions:
● When the Intelligent Key is not within the
operational range.
● When the doors or the trunk are open or not
closed securely.
● When the Intelligent Key battery is dis-
charged.
