Features of your vehicle Do not arm the system until all passengers have left the vehicle. If the system is armed while a passenger(s) remains in the vehicle, the alarm may be activated when the remaining passenger(s) leave the vehicle. If any door (or trunk) or engine hood is opened within 30 seconds after the system enters the armed stage, the system is disarmed to prevent an unnecessary alarm. Theft-alarm stage The alarm will be activated if any of the following occurs while the system is armed. • A door is opened without using the transmitter (or smart key or mechanical key). • The trunk is opened without using the transmitter (or smart key). • The engine hood is opened. The horn will sound and the hazard warning lights will blink continuously for approximately 30 seconds, and the alarm will repeat once more unless the system is disarmed. To turn off the system, unlock the doors with the mechanical key or transmitter or smart key. Opening the trunk with the alarm armed (if equipped) When the alarm is armed, the alarm will not sound if the trunk lid is opened with the transmitter (or smart key). Once the trunk is opened and then closed, the trunk will be locked automatically and the system will be armed again. Also, if any of the doors or hood is opened while the trunk lid is open and the alarm is armed, the alarm will sound. 4 16
