Your vehicle has two types of security systems:
Vehicle security system
NISSAN Vehicle Immobilizer System
The vehicle security system provides visual
and audible alarm signals if someone
opens the doors, liftgate or the hood 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.
