ArticStart systems have a setting called 'passive arming' that will cause the vehicle to lock and arm itself automatically 30 seconds after exiting the vehicle.
There is also a feature called 'drive lock' that will automatically lock the vehicle doors after the engine has been turned on. Drive lock will activate once the foot brake is pressed while the key is in the ignition and the engine is running.
These features are only accessible to the technician completing the installation. If you decide to activate them, please bring your vehicle to the local place of installation or an authorized dealer.
