Hill-descent controls speed by means of brake intervention and engine drag torque, whilst constantly maintaining the speed depending on the surface. The driver just has to steer, but does not have to accelerate or brake.
Automatically initiates preventive occupant protection measures if required. These include: belt tensioning, activating the hazard warning system and closing the sliding sunroof (if ordered) and windows; categorises driving situations by networking the different vehicle systems.
For driver and front-passenger; 2-stage deployment depending on the strength of impact and size of the person; front & rear side airbags incorporated into the seat backrests; head airbag system protects front and outer rear passengers in the event of a side impact; unfolds as a protective cushion over the side windows.
Maintenance-free rack & pinion steering with speed-dependent servo assistance; precise steering feel at high speeds, excellent assistance when parking; active countersteering provides steering assistance to the driver for enhanced vehicle stability.
Networks ABS, ASR and EDL with its own sensors and compares the driving data with reference data; provides better stability by targeted braking of individual wheels and intervention in the engine management system, passive rollover and brake disc wiping functions.
