The most important and noticeable upgrades to the RX 350 Premium+ is the addition of leather upholstery and a larger 14-inch infotainment touchscreen, complete with a three-year trial Drive Connect subscription with cloud navigation, Destination Assist, and the Hey Lexus assistant. The interior also gains custom thematic ambient lighting, a wood-and-leather steering wheel, and a smog-sensing climate-control system with an automatic recirculation mode.
