And if you need to leave the paved road for a quick excursion off the beaten track, the optional off-road engineering package will be of great service: pressing the Off-Road button is all it takes for the Off-Road driving programme to take over. It adapts the gearshift points and the accelerator pedal map to the precise requirements of the terrain. The off-road engineering package also includes the DSR downhill speed regulation function, which is also activated at the touch of a button, an underride guard and underbody protection, as well as a three-spoke leather steering wheel with shift paddles. For you to be informed about your geographic data at all times, the off-road engineering package expands on the functionalities of the optional COMAND APS: it tells you your bearing, altitude and GPS coordinates.
