Comfort and Convenience
Some occupants like a cooler cabin on a long stretch, while others prefer milder air, because clothing choices and how readily they feel warmth differ from person to person.
Safety and Driver Assistance
Learning the demister and fan switches in a quiet car park means the hand already knows the motion if the screen mists after a cold start.
Multimedia and Connectivity
A common need is taking a short call without holding the phone. If a speaker function is available, the handset can rest aside during the conversation.
