Your vehicle may have two types of security sys-
tems:● 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 lid when the system is armed. It is not,
however, a motion detection type system that
activates when a vehicle is moved or when a
vibration occurs.
The system helps deter vehicle theft but cannot
prevent it, nor can it prevent the theft of interior or exterior vehicle components in all situations. Al-
ways secure your vehicle even if parking for a
brief period. Never leave your Intelligent Key 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 protection, such
as component locks, identification markers, and
tracking systems, are available at auto supply
stores and specialty shops. Your NISSAN dealer
may also offer such equipment. Check with your
insurance company to see if you may be eligible
for discounts for various theft 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 vehicle.
3. Close all doors, hood and trunk. Lock all doors. The doors can be locked with the
Intelligent Key, door handle request switch
(if so equipped) , power door lock switch or
mechanical key.
4. Confirm that the security indicator light comes on. The security light stays on for
about 30 seconds. The vehicle security sys-
tem is now pre-armed. After about 30 sec- onds the vehicle security system automati-
cally shifts into the armed phase. The
security light begins to flash once every 3
seconds. If, during the 30-second pre-arm
time period, the driver’s door is unlocked by
the key or the keyfob, or the ignition switch is
placed in the ACC or ON position, the sys-
tem will not arm.
● Even when the driver and/or passen-
gers are in the vehicle, the system will
activate with all the doors, hood and
trunk lid 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 after ap-
proximately 50 seconds. 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

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 the driver’s
door or the trunk lid with the key, pressing
the

NISSAN INTELLIGENT KEY™
Your vehicle can only be driven with the Intelligent
Key which are registered to your vehicle’s Intelli-
gent Key components and NISSAN Vehicle Im-
mobilizer System components.
Never leave these keys in the vehicle.
As many as four Intelligent Keys can be regis-
tered and used with one vehicle. The new keys
must be registered by a NISSAN dealer prior to use with the Intelligent Key and NISSAN Vehicle
Immobilizer System of your vehicle. Since the
registration process requires erasing all memory
in the Intelligent Key components when register-
ing new keys, be sure to take all Intelligent 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, see 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, your NISSAN dealer
can duplicate it.

Mechanical key
The Intelligent Key contains the mechanical 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, trunk lid, glove box and rear seatback lock.
See “Doors” and “Trunk lid” in this section, “Stor-
age” in the “Instruments and controls” section,
“Seats” in the “Safety — Seats, seat belts and
supplemental restraint system” section, and “Up-per tether anchor/key cylinder covers” in the
“Maintenance and do-it-yourself” section of this
manual.

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.
