Comfort and Convenience
Keyless entry works by the car detecting the fob's short-range radio reply as the handle is touched, unlocking without a key press. With the fob aboard, the start button then energises the ignition directly.
Safety and Driver Assistance
A driver's airbag acts where observation cannot: once an impact is already underway, crash sensors fire the inflator in milliseconds, spreading head and chest loads across a cushion rather than the steering wheel rim.
Multimedia and Connectivity
The AUX input carries a plain analogue audio signal, so the head unit simply amplifies whatever the connected device sends. It transfers no track names or control data, unlike a USB or Bluetooth connection.
