How does the Vios automatically lock?

[DanielFitz]

The Vios automatically locks without any adjustment needed; it is enabled by default. According to the Vios vehicle documentation, the automatic door locking is controlled by the central locking system, which receives signals from the vehicle's anti-theft computer. The anti-theft computer, in turn, receives speed signals from the instrument panel. When the vehicle speed exceeds 20 km/h, the anti-theft computer sends a door-locking signal, triggering the automatic lock. Here are some related details: 1. Anti-theft function: The automatic door-locking feature has long been a subject of debate. It serves as both a safety and anti-theft function, typically activating when the vehicle reaches a certain speed. Its primary purpose is to prevent doors from suddenly opening while driving, thereby avoiding accidents. 2. Varied settings: The activation of automatic locking varies by manufacturer. Some vehicles automatically lock the doors when reaching a certain speed, while others activate based on the gear position—for example, shifting to D (Drive) triggers the automatic lock. Some vehicles even use brake pedal input to initiate locking, all of which are fully automatic methods.
