Main Menu Table Of Contents Security System The security system helps to protect your vehicle and valuables from theft. The horn sounds and a combination of headlights, position lights, side marker lights and taillights flashes if someone attempts to break into your vehicle or remove the audio unit. This alarm continues for 2 minutes, then the system resets. To reset an activated system before the 2 minutes have elapsed, unlock the driver's door with the key or the remote transmitter. The security system automatically sets 15 seconds after you lock the doors, hood, and the tailgate. For the system to activate, you must lock the doors and the tailgate from the outside with the key, driver's lock tab, door lock master switch, or remote transmitter. The security system indicator on the instrument panel starts blinking immediately to show you the system is setting itself. The security system will not set if the hood, tailgate, or any door is not fully closed. If the system will not set, check that the doors, the tailgate and the hood are fully closed. Do not attempt to alter this system or add other devices to it. Features SECURITY SYSTEM INDICATOR Once the security system is set, opening any door, the tailgate, or the hood without using the key or the remote transmitter, will cause it to alarm. It also alarms if the radio is removed from the dashboard or the wiring is cut. 2009 MDX 269
