Optional cruise control helps you stay within the speed limit, it also helps you to save fuel by maintaining a constant speed.
Also available as an option in conjunction with Porsche Doppelkupplung (PDK) is the enhanced version of cruise control, which regulates the speed of your vehicle in line with the speed of the vehicle in front. A radar sensor scans the road ahead up to a distance of 200 m.
You have selected a cruising speed but have begun to gain on the vehicle in front because it is driving more slowly – this is detected by the radar sensor. The system now reduces the speed of your vehicle by restricting throttle or by gently applying the brakes until your chosen distance from the vehicle in front is maintained. If the vehicle ahead slows further, adaptive cruise control will decelerate your vehicle accordingly – even down to a halt.
For increased safety, the system also readies the brakes whenever it detects that the distance from the vehicle is decreasing. However, the driver should be prepared to intervene manually if heavier braking is required. As soon as the road ahead clears, your vehicle will accelerate back up to the cruising speed originally set. Porsche Active Safe (PAS) issues an audible and a visual warning if the system detects that your vehicle is approaching the vehicle in front too quickly. This is accompanied by a brief application of brake force and, where necessary, the initiation of targeted braking. During this process, any braking by the driver is boosted to achieve the maximum braking force that the system is able to provide.
The optional speed limit indicator informs you about speed limits, overtaking restrictions and when they are lifted, as recorded by a camera near the rear view mirror. The information is displayed on the color screen in the instrument cluster or the optional Porsche Communication Management (PCM). If a traffic sign is not identified, for example in heavy rain or when it is dark, the speed limit stored in the navigation module will be automatically displayed. The advantage for you is that you can give your full concentration to the traffic.
Optional ParkAssist is activated the moment you select reverse gear. An audible signal gives a warning if you reverse too close to an obstacle. An enhanced version of ParkAssist also provides monitoring of the area to the front of the vehicle. Ultrasonic sensors are neatly integrated into the front and rear aprons. The audible alert is supplemented by a visual warning in the central display of the CDR audio system, optional CDR Plus or optional PCM, which shows a graphical representation of the vehicle from overhead.
Comfort, even when reversing. The optional reversing camera using a camera image and dynamic guidelines to help you with precise parking and manoeuvring.
