Comfort and Convenience
The listed engine start button replaces the twist of a key barrel, authorising ignition once the keyless system recognises the fob nearby. It governs starting only, not how quickly the cabin warms or cools afterwards.
Safety and Driver Assistance
Listed hill start assist briefly holds brake pressure after the pedal is released on an incline, so the car does not roll back during the changeover to the accelerator. It assists that transition; it does not protect in a collision.
Multimedia and Connectivity
The listed audio system is the part that produces sound; USB, AUX and Bluetooth are only routes that carry a signal to it. A working connection says nothing about whether a given file or app format will play.
