Comfort and Convenience
With the start-stop system, holding the brake at a halt lets the engine switch off; releasing the brake restarts it automatically, so idling stops without the driver touching the key or ignition button.
Safety and Driver Assistance
On a slippery bend or during a sudden swerve, the electronic stability program detects that the car is turning more or less than steered and brakes individual wheels, though grip limits still apply.
Multimedia and Connectivity
Bluetooth handles the wireless link itself: once a phone is paired, calls route through the car's speakers and microphone and audio streams over the same connection, with no cable involved.
