KEYS AND DOORS THEFT DETERRENT SYSTEM 17L014a 17L013 "Security indicator light To deter theft of the vehicle, this system is designed to sound an alarm if any of the doors, trunk or hood is forcibly unlocked or opened or the battery terminal is disconnected and then reconnected while the vehicle is locked. The alarm blows the horn intermittently, flashes the headlights, tail lights, turn signal lights and other exterior lights. When the interior light switch is in the "DOOR" position, the interior lights also turn on. After the alarm is activated, when you unlock any door or the trunk using an ignition key or wireless remote control or smart key system, the tail lights turn on for about 2 seconds to inform you that the system was activated. Setting the system In the case of the smart key system: 1. Turn the ignition switch to the "LOCK" position. The engine immobilizer system causes to the indicator light to flash. 2. Close and lock all the doors, trunk and hood using an ignition key or wireless remote control or smart key system. If you lock them with wireless remote control or smart key system, the turn signals flash once.* NOTE: * The turn signals can be set not to flash. Ask your Lexus dealer for details. 50
