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 and the moonroof.
The system can be armed even if the
windows and moonroof are open.
2. Remove the Intelligent Key from the ve- hicle.
3. Close all doors, hood and trunk. Lock all doors. The doors can be locked with
the Intelligent Key, door handle request
switch, power door lock switch or me-
chanical key (if so equipped).
