Comfort and Convenience
The on-board computer is cycled manually through its readouts, usually by a stalk or steering-wheel button, and each trip counter is reset by holding that control until the figures return to zero.
Safety and Driver Assistance
A collision avoidance system reacts only once a closing hazard is detected, and braking still depends on grip and load transfer, so a gap that allows the driver to lift off early remains the primary margin.
Multimedia and Connectivity
The audio system is the common output stage: whichever source the driver selects, its amplifier and speakers reproduce it, so volume, balance and tone settings apply across sources rather than to one input alone.
