Comfort and Convenience
Cabin temperature is a personal matter: one person settles happily at a cool setting while another finds the same air chilly. Build, clothing and seating position all play a part, so agreeing a compromise early saves constant fiddling.
Safety and Driver Assistance
Before setting off, it is worth locating the hazard lights, the demisting function and the horn, rather than hunting for them in moving traffic. A stationary minute spent on the layout counts as preparation.
Multimedia and Connectivity
A phone battery drains quickly when navigation runs all day, so a charging point, where one is available, often matters more than sound quality. Calls and music are separate needs and each has its own settings.
