Switching on and off via the ignition (permanently)
Switch on the ignition.
The PCM is permanently active.
Switching on and off using the left rotary knob
If the PCM is not to be permanently active, you can also switch it on and off using the left rotary knob.

Battery discharge protection
You can switch the PCM on and off via the left rotary knob even when the ignition is off.
To protect your vehicle's battery, the PCM will automatically switch itself off again after a few minutes.
Risk of damage. The PCM contains high-quality electronic components which require special care with regard to maintenance.
The following should be observed:
– The display scratches easily.
– The device must not be sprayed with liquids. Entrance of liquids into the unit can result in the destruction of the equipment.
Carefully clean your PCM periodically using a dry, clean, and soft cloth (micro-fiber cloth) or a cleaning brush.
Do not exert excessive pressure on the surface when cleaning.
Under no circumstances should solvents such as methylated spirits, thinners, gasoline, acetone as well as alcohol (ethanol, methanol, or isopropyl alcohol) or scouring agents of any type be used.
Remove fingerprints using a slightly damp cloth or a mild cleaning agent.
Never spray cleaning agents or other liquids directly onto the display. Instead, moisten a cloth and then carefully wipe the display.
If faults occur, do not open the PCM equipment yourself under any circumstances. Always have defective units repaired by a qualified specialist workshop. We recommend that this work be performed by an authorized Porsche dealership, as these have trained workshop personnel as well as the necessary parts and tools.
