NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of a registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedures:
1. Leave the ignition switch placed in the ON position for approximately 5 sec-
onds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat Steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the in-
terference) separate from the regis-
tered key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices.

The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-
held transmitters into one built-in device.
HomeLink® Universal Transceiver:∙ Will operate most radio frequency de- vices such as garage doors, gates,
home and office lighting, entry door
locks and security systems.
∙ Is powered by your vehicle’s battery. No separate batteries are required. If the
vehicle’s battery is discharged or is dis-
connected, HomeLink® will retain all
programming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming pro-
cedures (Example: new vehicle pur-
chases). Upon sale of the vehicle, the
programmed HomeLink® Universal
Transceiver buttons should be erased
for security purposes. For additional
information, refer to “Programming
HomeLink®” in this section.WARNING
∙ 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. ∙ Your vehicle’s engine should be
turned off while programming the
HomeLink® Universal Transceiver. Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death.
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 (if so equipped) when programming
HomeLink®. It is also recommended that
a new battery be placed in the hand-held
transmitter of the device being pro-
grammed to HomeLink® for quicker pro-
gramming and accurate transmission of
the radio frequency.
