Comfort and Convenience
The on-board computer acts on the instrument cluster display, drawing trip and consumption readings into the driver's line of sight so that checking range does not mean reaching for a separate gauge or switch.
Safety and Driver Assistance
ABS responds when a wheel begins locking under heavy braking, releasing and reapplying pressure at that wheel so it keeps turning, which preserves the steering response the driver needs to aim around an obstacle.
Multimedia and Connectivity
The AUX input carries plain analogue audio, so a connected player handles track selection itself. Choosing what plays stays on the source device, while the car simply amplifies the incoming signal through its speakers.
