Comfort and Convenience
Keyless entry unlocks the doors while the fob stays in a pocket, which is about access only; it does not adjust seats, mirrors or cabin temperature once you are inside.
Safety and Driver Assistance
On a slippery bend or during a sudden swerve, the stability program can brake individual wheels to curb a skid. It works within available grip, so it cannot recover every slide.
Multimedia and Connectivity
Bluetooth is the wireless link between phone and head unit; the call or track it carries comes from the phone, so changing source does not alter the pairing itself.
