Toyota Highlander offers a range of features to enhance your security and convenience. Arm and disarm the security system remotely using your vehicle's keyless entry system. The system automatically re-arms if no door is opened within 30 seconds of remote disarming. It also protects against theft by monitoring point-of-entry, glass breakage, and the ignition switch. In the event of an alarm, the system flashes the lights, sounds the horn, and disables the starter.
