The system uses radar sensors to monitor the zone behind the vehicle and in the blind spot. Operational over a speed range from 30 km/h to 250 km/h, the assistant informs the driver of any vehicles that are approaching quickly from the rear or are driving in the blind spot. It does this via a glowing warning indicator in the car's mirror triangle. During this hazardous condition, if the driver sets the turn indicator or the system detects that the driver is making a lane change, the warning signal lights four times in succession. The lane departure warning assistant thereby enhances comfort and safety, especially on motorways. However, it does not intervene in vehicle control, and it can be deactivated at any time.

The further developed optional cruise control system can now brake and thereby maintain a constant speed even on route segments with steep descents. The control range of the cruise control system is from 30 km/h to 240 km/h. Adaptive Cruise Control (ACC) in conjunction with Porsche Doppelkupplung (PDK) can now also perform the typical Porsche coasting functionality. At the appropriate speed, both clutches disengage, the engine begins to idle, and the sports car coasts in the queue of vehicles without engine propulsion, thereby saving on fuel.
