Comfort and Convenience
The listed cigarette lighter and ashtray matter mainly while travelling: the socket delivers heated resistance on demand, and the covered ashtray contains ash and odour instead of letting it scatter through the ventilated cabin.
Safety and Driver Assistance
The driver's airbag responds only to a sufficiently severe frontal impact, when sensors trigger inflation so the torso and head meet a cushion rather than the steering wheel. Side or rear impacts fall outside its response.
Multimedia and Connectivity
The USB connection carries digital data and power, so the head unit reads files and controls tracks. The listed AUX input, by contrast, accepts only an analogue signal, leaving volume and selection to the device.
