Keyfob operation: ● Push the button on the keyfob. All doors lock. The hazard lights flash twice and the horn beeps once to indicate all doors are locked. ● When the button is pushed with all doors locked, the hazard lights flash twice and the horn beeps once as a reminder that the doors are already locked. The horn may or may not beep. Refer to "Silencing the horn beep feature" in the "Pre-driving checks and adjustments" section later in this manual. 4. Confirm that the indicator light comes on. The light stays on for about 30 seconds. The vehicle security system is now pre-armed. After about 30 seconds the vehicle security system automatically shifts into the armed phase. The light begins to flash once every 3 seconds. If, during the 30-second pre-arm time period, the driver's door is unlocked by the key or the keyfob, or the ignition key is turned to ACC or ON, the system will not arm. ● If the key is turned slowly when locking the driver's door, the system may not arm. Furthermore, if the key is turned beyond the vertical position toward the unlock position to remove the key, the system may be disarmed when the key is removed. If the indicator light fails to glow for 30 seconds, unlock the door once and lock it again. ● Even when the driver and/or passengers are in the vehicle, the system will arm with all doors closed and locked with the ignition key in the OFF position. How to stop an activated alarm The alarm stops only by unlocking the driver's door with the key, or by pressing the button on the keyfob. NISSAN VEHICLE IMMOBILIZER SYSTEM (if so equipped) 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 automated toll road device or automatic payment device on the key ring), restart the engine using the following procedures: 1. Leave the ignition switch in the ON position for approximately 5 seconds. 2. Turn the ignition switch to the OFF or LOCK position, and wait approximately 10 seconds. 3. Repeat steps 1 and 2. 4. Restart the engine while holding the device (which may have caused the interference) separate from the registered key. 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 with the key, or by pressing the button on the keyfob. The alarm is activated by: ● opening a door without using the key or keyfob (even if the door is unlocked by using the inside lock knob or the power door lock switch). 2-22 Instruments and controls
