Where is the central locking system located on the Baojun 310?

[Petunia]

The central locking switch for the Baojun 310 is located on the left front door trim panel. Central control: When the driver locks their door, all other doors are simultaneously locked. The driver can use the door lock switch to open all doors at once or open individual doors separately. Speed control: When the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening doors by operating the door handles. Working principle of central locking: When the central locking system receives the correct code signal, the control wave receiving circuit is triggered to extend reception time by 0.5 seconds before returning to standby mode. If the input code signal doesn't match, the receiving circuit won't be triggered.
