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 two minutes, then the system resets. To deactivate the system before the two 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 tailgate. For the system to activate, you must lock the doors from the outside with the key, or use 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 does not set if any door, the tailgate, or hood is not fully closed. Before you leave the vehicle, make sure the doors, tailgate and hood are securely closed. To see if the system sets after you exit the vehicle, press the LOCK button on the remote transmitter within five seconds. If the system is set, the horn will beep once. SECURITY SYSTEM INDICATOR Features Once the security system sets, opening any door, tailgate, or hood without using the key or the remote transmitter, will cause the alarm to activate. It also activates if the ignition switch is turned to the ON (II) position, the audio unit is removed from the dashboard or the wiring is cut. Do not attempt to alter this system or add other devices to it. 341
