VEHICLE SECURITY SYSTEM (if so
equipped)
The vehicle security system provides visual
and audible alarm signals if someone
opens the doors 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 detect 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 and the moonroof (if
so equipped). The system can be
armed even if the windows and moon-
roof are open.
2. Remove the Intelligent Key from the vehicle.

• The ignition switch is placed in the AUTO ACC or ON position.
• Even when the driver and/or passen-
gers are in the vehicle, the system will
activate when all the doors, hood and
trunk are locked with the ignition
switch placed in the LOCK position.
When placing the ignition switch in the
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

vates if the vehicle is tampered with
again. The alarm can be shut off by un-
locking 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 us- ing the key or Intelligent Key (even if the
door is unlocked by releasing the door

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 in the ON posi-
tion for approximately 5 seconds.
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 de- vice (which may have caused the inter-
ference) separate from the registered
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.
Never leave these keys in the vehicle.

NISSAN INTELLIGENT KEY®
Your vehicle can only be driven with the
Intelligent Keys which are registered to
your vehicle’s Intelligent Key components
and NISSAN Vehicle Immobilizer System
components.Never leave the 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 and NISSAN Vehicle
Immobilizer System of your vehicle. It is rec-
ommended that you visit a NISSAN dealer
for this service. Since the registration pro-
cess 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 a 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.
CAUTION
Listed below are conditions or occur-
rences which will damage the Intelli-
gent Key:
• Do not allow the Intelligent Key,
which contains electrical compo-
nents, to come into contact with wa-
ter or salt water. This could affect the
system function.
• Do not drop the Intelligent Key.
• Do not strike the Intelligent Key
sharply against another object.
• Do not change or modif y the Intelli-
gent Key.

KEYS
3-2Pre-driving checks and adjustments

•Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet,
immediately wipe until it is com-
pletely dry.
• Do not place the Intelligent Key for an
extended period in an area where
temperatures exceed 140°F (60°C).
• Do not attach the Intelligent Key with
a key holder that contains a magnet.
• Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment
and personal computers.
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 unau-
thorized use of the Intelligent Key to
operate the vehicle. For information re-
garding the erasing procedure, it is rec-
ommended 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 driver's door.
For additional information, see “Doors”
(P. 3-4).
CAUTION
Always carry the mechanical key in-
stalled in the Intelligent Key slot.
NISSAN VEHICLE IMMOBILIZER
SYSTEM KEYS
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
given to the dealer at the time of registra-
tion will no longer be able to start your
vehicle.

Pre-driving checks and adjustments3-3

CAUTION
Do not allow the immobilizer system
key, which contains an electrical tran-
sponder, to come into contact with wa-
ter or salt water. This could affect sys-
tem function. When the doors are locked using one of the
following methods, the doors cannot be
opened using the inside or outside door
handles. The doors must be unlocked to
open the doors.
WARNING
• Always have the doors locked while
driving. Along with the use of seat
belts, this provides greater safety in
the event of an accident by helping to
prevent persons from being thrown
from the vehicle. This also helps keep
children and others from uninten-
tionally opening the doors, and will
help keep out intruders.
• Before opening any door, always look
for and avoid oncoming traffic. •
To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
