WARNING
∙ Your vehicle’s engine should beturned off while programming the
HomeLink® Universal Transceiver. For
additional information, refer to
“Push-button ignition switch” in the
“Starting and driving” section of this
manual. Do not breathe exhaust
gases; they contain colorless and
odorless carbon monoxide. Carbon
monoxide is dangerous. It can cause
unconsciousness or death.
∙ Do not use the HomeLink® Universal Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982.) A
garage door opener which cannot de-
tect an object in the path of a closing
garage door and then automatically
stop and reverse does not meet cur-
rent federal safety standards. Using a
garage door opener without these
features increases the risk of serious
injury or death. ∙ During the programming procedure
your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage door,
gate, etc., that you are programming.
PROGRAMMING HOMELINK®
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.
NOTE:
Place the ignition switch in the ON posi-
tion (without starting the engine) when
programming HomeLink®. It is also rec-
ommended that a new battery be placed
in the hand-held transmitter of the de-
vice being programmed to HomeLink®
for quicker programming and accurate
transmission of the radio frequency. 1. Position the end of your hand-held
transmitter 1–3 in (2–8 cm) away from
the HomeLink® surface, keeping the
HomeLink® indicator light
1in view.

NISSAN INTELLIGENT KEY®
Your vehicle can only be driven with the
Intelligent Keys which are registered to
your vehicle’s Intelligent Key system com-
ponents and NISSAN Vehicle Immobilizer
System components.Never leave these keys in the vehicle.
As many as four Intelligent Keys can be
registered and used with one vehicle. The
new keys must be registered prior to use
with the Intelligent Key system and NISSAN
Vehicle Immobilizer System of your vehicle.
It is recommended that you visit a NISSAN
dealer for this service. Since the registra-
tion process requires erasing all memory in
the Intelligent Key components when reg-
istering new keys, be sure to take all Intelli-
gent Keys that you have to the NISSAN
dealer.
A key number plate is supplied with your
keys. Record the key number and keep it in
a safe place (such as your wallet), not in the
vehicle. If you lose your keys, it is recom-
mended that you visit a NISSAN dealer for
duplicates by using the key number.
NISSAN does not record key numbers so it
is very important to keep track of your key
number plate.
A key number is only necessary when you
have lost all keys and do not have one to
duplicate from. If you still have a key, it can
be duplicated without knowing the key
number.

If an Intelligent Key is lost or stolen, NISSAN
recommends erasing the ID code of that
Intelligent Key from the vehicle. This may
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.
Mechanical key
The Intelligent Key contains the mechani-
cal key.
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.
Use the mechanical key to lock or unlock
the doors and glove box.
For additional information, refer to “Doors”
in this section and “Storage” in the “Instru-
ments and controls” section of this manual.
