Cruise control is available as an option for the new Cayman models. This automatic speed controller for the 30 to 240 km/h speed range is operated by a switch on a separate control stalk on the steering column. The advantages are clear. Not only can cruise control be used as a means of staying within the speed limit, it also helps you to save fuel by maintaining a constant speed.
Also available as an option 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 inside the front centre air intake scans the road ahead up to a distance of 200 m. Imagine you’ve 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.
