Comfort and Convenience
Some travellers want fresh air moving constantly; others find a draught irritating and prefer vents directed away from them. Preference here follows personal sensitivity rather than any rule about the right setting.
Safety and Driver Assistance
Before setting off, it is worth sitting still for a moment and working through the indicator stalk, hazard switch and mirror adjustment. Unfamiliar layouts are easiest to learn while nothing else demands attention.
Multimedia and Connectivity
Hands-free calling matters when someone is expecting an arrival time, and it is a different question from how audio is played. Where pairing is supported, setting it up before departure avoids doing so later.
