Comfort and Convenience
Some people like a cooler cabin on a long afternoon, while others prefer warmer air around their feet. That split often comes down to clothing and personal habit rather than a single correct setting.
Safety and Driver Assistance
Before a dawn start, a quiet minute in the driveway to locate the demister, hazard switch, and main lights can save fumbling later when the cabin is still dark.
Multimedia and Connectivity
When someone at the destination calls to change a meeting point, a hands-free way of talking, if it is available, lets the driver leave the phone in a bag rather than hold it to the ear.
