Comfort and Convenience
Cabin temperature divides passengers more than almost anything else: some feel cold at a setting others call warm. Agreeing a compromise early avoids constant adjustments during a shared journey.
Safety and Driver Assistance
Controls sit in different places from car to car, so the hazard switch or demister may not be where habit expects. Checking their positions before pulling away means less fumbling when conditions change.
Multimedia and Connectivity
Listening habits vary: radio suits short errands, while stored or streamed music suits longer routes. If a system offers several sources, knowing which one is selected saves menu hunting at junctions.
