setup only when vehicle is stationary ne demek?

"Setup only when vehicle is stationary" means that certain operations, such as adjusting or modifying settings in a vehicle's onboard system, can only be performed when the vehicle is not in motion. This is to ensure the safety of the driver and passengers, as well as prevent distraction and potential accidents. In other words, if the vehicle is moving, the driver should not be making any changes to the settings or configuration of the vehicle's systems.
