Nissan Altima: 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 approximately 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 button on the Intelligent Key.
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).
