1. For additional information, refer to “Pro-gramming HomeLink®” step 1 in this
section.
2. Using both hands, simultaneously press and hold the desired HomeLink®
button and the hand-held transmitter
button. During training, your hand-held
transmitter may automatically stop
transmitting. Continue to press and
hold the desired HomeLink® button
while you press and re-press (“cycle”)
your hand-held transmitter every
2 seconds until the frequency signal
has been learned. The HomeLink® indi-
cator light will flash slowly and then
rapidly af ter several seconds upon
successful training. DO NOT release un-
til the HomeLink® indicator light flashes
slowly and then rapidly. When the indi-
cator light flashes rapidly, both buttons
may be released. The rapid flashing in-
dicates successful training.
Proceed with “Programming
HomeLink®” step 3 to complete.
If the device was unplugged during the
programming procedure, remember
to plug it back in when programming is
completed.OPERATING THE HOMELINK®
UNIVERSAL TRANSCEIVER
The HomeLink® Universal Transceiver, af ter
it is programmed, can be used to activate
the programmed device. To operate, sim-
ply press and release the appropriate pro-
grammed HomeLink® Universal Trans-
ceiver button. The amber indicator light will
illuminate while the signal is being trans-
mitted.
For convenience, the hand-held transmit-
ter of the device may also be used at any
time.
PROGRAMMING TROUBLE-
DIAGNOSIS
If the HomeLink® does not quickly learn the
hand-held transmitter information:
∙ Replace the hand-held transmitter bat- teries 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 interruption. ∙ Position the hand-held transmitter 1 -
3 inches (26 - 76 mm) away from the
HomeLink® surface. Hold the transmit-
ter 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 have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
CLEARING THE PROGRAMMED
INFORMATION
The following procedure clears the pro-
grammed information from both buttons.
Individual buttons cannot be cleared. How-
ever, individual buttons can be repro-
grammed. For additional information, refer
to “Reprogramming a single HomeLink®
button” in this section.
To clear all programming: 1. Press and hold the two outer HomeLink® buttons until the indicator
light begins to flash in approximately
10 seconds. Do not hold for longer than
20 seconds.
2-80Instruments and controls

Mechanical key
The Intelligent Key contains the mechani-
cal key, which can be used in case of a
discharged battery.
To remove the mechanical key, release the
lock knob on the back of the Intelligent Key.
To install the mechanical key, firmly insert it
into the Intelligent Key until the lock knob
returns to the lock position.
The mechanical key can be used for opera-
tion in the same way as an ordinary key.
CAUTION
Always carry the mechanical key in-
stalled in the Intelligent Key slot.
For additional information, refer to “Doors”
in this section and “Storage” in the “Instru-
ments and controls” section of this manual.
Valet hand-off
When you have to leave a key with a valet,
give them the Intelligent Key itself and keep
the mechanical key with you to protect
your belongings.
To prevent the glove box from being
opened during valet hand-off, follow the
procedures below. 1. Remove the mechanical key from the Intelligent Key.
2. Lock the glove box with the mechani- cal key.
3. Hand the Intelligent Key to the valet and keep the mechanical key with you.
For additional information, refer to “Stor-
age” in the “Instruments and controls” sec-
tion of this manual.
NISSAN VEHICLE IMMOBILIZER
SYSTEM KEYS
You can only drive your vehicle using the
Intelligent Keys which are registered to the
NISSAN Vehicle Immobilizer System com-
ponents in your vehicle.
The mechanical key can be used for all the
locks.
Never leave the keys in the vehicle.
Additional or replacement keys:
If you still have a key, the key number is not
necessary when you need extra NISSAN
Vehicle Immobilizer System keys. Your ex-
isting key can be duplicated without know-
ing the key number. As many as four
NISSAN Vehicle Immobilizer System keys
can be used with one vehicle. You should
bring all NISSAN Vehicle Immobilizer Sys-
tem keys that you have to the NISSAN
dealer for registration. This is because the
registration process will erase the memory
of all key codes previously registered into
the NISSAN Vehicle Immobilizer System. Af-
ter the registration process, these compo-
nents will only recognize keys coded into
the NISSAN Vehicle Immobilizer System
during registration. Any key that is not

Pre-driving checks and adjustments3-3

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, a
yellow indicator illuminates with the mes-
sage “Key Battery Low” in the vehicle infor-
mation display. For additional information,
refer to “Vehicle information display warn-
ings and indicators” in the “Instruments
and controls” section of this manual.
Since the Intelligent Key is capable of 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 additional information, 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.

If all doors are already unlocked, opening
the trunk does NOT require an Intelligent
Key to be in range of the trunk request
switch or rear of the vehicle.
When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key operating range becomes narrower,
and the Intelligent Key may not function
properly.

Intelligent Key button operation
light
The light blinks only when you push any
button on the Intelligent Key. The light illu-
mination only signifies that the key fob has
transmitted a signal. You may look and/or
listen to verif y that the vehicle has per-
formed the intended operation. The num-
ber of blinks identifies each registered key
(i.e. 1 blink = 1st key,...,4 blinks = 4th key) for
your own identification purposes. If the light does not blink, your battery may
be too weak to communicate to the ve-
hicle. If this occurs, the battery may need to
be replaced. For additional information re-
garding the replacement of a battery, refer
to “Battery replacement” in the “Do-it-
yourself ” section of this manual.
WARNING SIGNALS
To help prevent the vehicle from moving
unexpectedly by erroneous operation of
the Intelligent Key or to help prevent the
vehicle from being stolen, a chime or
buzzer sounds from inside and outside the
