Comfort and Convenience
An on-board computer is always running; the driver only chooses which readout appears. Cycling through consumption or range views changes the display, not the measurement, unlike climate control where the setting alters cabin conditions.
Safety and Driver Assistance
A passenger airbag acts after a crash has begun, in milliseconds no driver can react within. Observation helps avoid the impact; the airbag only limits how the occupant meets the interior once it happens.
Multimedia and Connectivity
An AUX input takes a 3.5 mm cable from a phone or player, and the audio system is switched to that source. The external device handles track selection; the car simply amplifies the analogue signal.
