Even the standard front seats are electrically adjustable and offer tremendous safety and comfort together with a wide choice of materials, plus special decorative stitching and quilting for the optional Dakota and Nappa leather trims. The optional sports seats feature adjustable side bolsters for optimum lateral support through even quickly-taken corners. The multifunction seats, which are available with a massage function, represent the pinnacle in comfort. Eight different massage programmes, each with a choice of three intensity modes, relax the muscles in the back and relieve the strain on the spinal discs while driving. The eight programmes are subdivided into three categories: Mobilisation, Relaxation and Vitality. The massage function uses 20 air chambers incorporated into the seat backrest and cushion, which are alternately inflated and deflated. The driver is furthermore able to set temperature thresholds for activating the seat heating and seat ventilation, as well as the steering wheel heating – a highly convenient feature which starts heating or ventilation automatically when the temperature falls below or rises above the respective limit.
