Comfort and Convenience
The on-board computer and multifunction steering wheel work together: the wheel buttons let you page through trip data, range and average consumption without taking a hand off the rim.
Safety and Driver Assistance
Hill start assist is most relevant when setting off on an incline: it holds brake pressure briefly after you release the pedal, giving time to move from brake to accelerator without rolling back.
Multimedia and Connectivity
The USB port establishes a wired data and charging link to a phone or media player, so the head unit can read audio files and power the device at the same time.
