Nissan really ups the ante with the SL in terms of comfort and convenience, installing it with a heated leather-clad steering wheel, front seat heating, and two-way power lumbar support to the drivers seat. The front passenger seat is also upgraded with four-way power adjustability and all seats are upholstered in leather. You also get dual-zone automatic climate control. The infotainment system is further upgraded with a premium nine-speaker Bose audio system. Finally, ProPilot Assist, Intelligent Lane Intervention, and traffic sign recognition are added.
