systems:
∙ Vehicle security system
∙ NISSAN Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual
and audible alarm signals if someone
opens the doors or trunk when the system
is armed. It is not, however, a motion detec-
tion type system that activates when a ve-
hicle is moved or when a vibration occurs.
The system helps deter vehicle thef t but
cannot prevent it, nor can it prevent the thef t of interior or exterior vehicle compo-
nents in all situations. Always secure your
vehicle even if parking for a brief period.
Never leave your keys in the vehicle, and
always lock the vehicle when unattended.
Be aware of your surroundings, and park in
secure, well-lit areas whenever possible.
Many devices offering additional protec-
tion, such as component locks, identifica-
tion markers, and tracking systems, are
available at auto supply stores and spe-
cialty shops. A NISSAN dealer may also offer
such equipment. Check with your insur-
ance company to see if you may be eligible
for discounts for various thef t protection
features.
How to arm the vehicle security
system
1. Close all windows.
(The system can be
armed even if the windows are open.)
2. Remove the Intelligent Key from the ve- hicle.
3. Close all doors. Lock all doors. The doors can be locked with the Intelligent
Key, door handle request switch, or me-
chanical key.

SECURITY SYSTEMS
Instruments and controls2-31

4. Confirm that thesecurity indica-
tor light stays on for about 30 seconds.
The vehicle security system is now pre-
armed. The vehicle security system will
automatically shif t into the armed
phase. The
security light begins
to flash once every three seconds. If
during the pre-armed phase one of the
following occurs, the system will not
arm:
∙ Any door is unlocked with the mechani- cal key, the Intelligent Key or door re-
quest switch.
∙ Ignition switch is placed in ACC or ON position.
∙ If the key is turned slowly when lock-
ing the door, the system may not arm.
Furthermore, if the key is turned be-
yond the vertical position toward the
unlock position to remove the key,
the system may be disarmed when
the key is removed. If the indicator
light fails to glow for a period of time,
unlock the door once and lock it
again. ∙
Even when the driver and/or passen-
gers are in the vehicle, the system will
activate with all the doors closed and
locked with the ignition switch placed
in the LOCK position. When placing
the ignition switch in the ACC or ON
position, the system will be released.
Vehicle security system activation
The vehicle security system will give the
following alarm:
∙ The headlights blink and the horn sounds intermittently.
∙ The alarm automatically turns off af ter a period of time. However, the alarm
reactivates if the vehicle is tampered
with again. The alarm can be shut off by
unlocking the driver’s door or trunk lid
with the key, or by pressing the
button on the Intelligent Key.
The alarm is activated by:
∙ opening the door or trunk lid without using the key or Intelligent Key (even if
the door is unlocked by releasing the
door inside lock switch).
How to stop an activated alarm
The alarm stops only by unlocking a door
or the trunk with the mechanical key, push- ing the
button on the Intelligent Key,
or pushing the request switch on the driv-
er’s or passenger’s door with the Intelligent
Key in range of the door handle.
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.

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 infor-
mation, 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 ACC posi-
tion when programming HomeLink®. It is
also recommended that a new battery
be placed in the hand-held transmitter
of the device being programmed to
HomeLink® for quicker programming
and accurate transmission of the radio
frequency.
