Auto Start Stop Function - Porsche Cayman Owner's Manual

Auto Start Stop Function

On vehicles with PDK transmission or manual
transmission, the engine stops automatically
when the vehicle is stopped, e.g. at traffic lights
or in a traffic jam. The Auto Start Stop function
thus helps to save fuel.
The ignition stays on even when the engine
switches off automatically. All functions are still
available.

approx. 1 mph (2 km/h) for at least
