Security Alarm System

~1min read

This system helps protect your vehicle and its valuables. The horn will sound and the hazard warning lights will flash continuously if one of the following occurs:

- A door is opened without using the Smart Key.
- The tailgate is opened without using the Smart Key.
- The hood is opened.

The alarm continues for 30 seconds, then the system resets. To turn off the alarm, unlock the doors with the Smart Key.

The security alarm system activates automatically 30 seconds after you lock the doors and the tailgate. For the system to arm, you must lock the doors and the tailgate from outside the vehicle using the Smart Key or by pressing the button on the outside door handles while carrying the Smart Key.

The hazard warning lights will flash and the horn will sound once to indicate that the system is armed. Once the security system is armed, opening any door, the tailgate, or the hood without using the Smart Key will trigger the alarm.

The security alarm system will not arm if the hood, tailgate, or any door is not fully closed. If the system does not arm, check that the hood, luggage compartment door, and doors are fully closed.

Do not attempt to modify this system or add other devices to it.

Information

  • Do not lock the doors until all passengers have left the vehicle. If a remaining passenger leaves the vehicle while the system is armed, the alarm will be triggered.
  • If the vehicle is not disarmed with the electronic key, open the doors with the mechanical key and start the vehicle by pressing the ENGINE START/STOP button with the smart key.
  • When the system is disarmed but the door or tailgate is not opened within 30 seconds, the system will re-arm.
