Comfort and Convenience
Keyless entry works by recognising the key fob carried nearby, so doors can be unlocked without taking it out. It governs access only; locking behaviour and cabin settings remain separate functions handled elsewhere.
Safety and Driver Assistance
Emergency brake assist reacts when the brake pedal is pressed unusually fast, reading that speed as a panic stop and immediately applying full braking pressure, since many drivers press hard but not hard enough.
Multimedia and Connectivity
The USB connection carries a wired data link between phone and head unit, which is the part that lets stored audio files play through the car speakers and supports the smartphone projection interfaces.
