any one of the following improper opera-
tions is found.

• The Intelligent Key is taken outside the vehicle when operating the vehicle.
• Any doors are not closed securely when locking the doors.
When the buzzer sounds, be sure to check
both the vehicle and the Intelligent Key.
For additional information, see “NISSAN In-
telligent Key®” (P. 3-2).
Parking brake reminder chime

Vehicle ahead detection
indicator
This indicator appears when the following
systems are engaged and have detected a
vehicle:
• Automatic Emergency Braking (AEB) withPedestrian Detection
• Intelligent Forward Collision Warning (I-FCW)
For additional information, see “Automatic

Your vehicle may have two types of security
systems:
• Vehicle security system (if so equipped)
• NISSAN Vehicle Immobilizer System
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.

3. Close all doors, hood and trunk. Lock alldoors. The doors can be locked with the
Intelligent Key, door handle request
switch (if so equipped) or power door
lock switch.
4. Wait 30 seconds for the system to com- plete the pre-armed phase.
If during the pre-armed phase one of
the following occurs, the system will not
arm:
• Any door is unlocked with the Intelli- gent Key or door request switch (if so
equipped).
• 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
period of time. However, the alarm reacti-
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
inside lock switch).
How to stop an activated alarm
The alarm stops only by unlocking a door
or the trunk, pressing thebutton on
the Intelligent Key, or pushing the request
switch (if so equipped) on the driver'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 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.
FCC Notice:
For USA:
This device complies with Part 15 of the
FCC Rules. Operation is subject to the fol-
lowing two conditions: (1) This device
may not cause harmful interference, and
(2) this device must accept any interfer-
ence received, including interference
that may cause undesired operation.
