Switching the PCM on/off

Switching on/off via the ignition

Switching on/off via the left rotary knob is also
possible when the ignition is off.
To protect your vehicle's battery, the PCM will au-
tomatically switch itself off again after a few min-
utes.
NOTICE
Risk of damage. The PCM contains high-qual-
ity electronic components which require spe-
cial care with regard to maintenance.
The following should be observed:
– The display is sensitive to scratches.
– The device must not be sprayed with liq-
uids. Ingress of liquids can result in the de-
struction of the equipment.
û Carefully clean your PCM periodically using
a dry, clean and soft cloth (microfibre cloth)
or a cleaning brush.
û Do not exert excessive pressure on the sur-
face when cleaning.
û Under no circumstances may solvents
such as methylated spirits, thinners, petrol,
acetone or alcohol (ethanol, methanol or
isopropyl alcohol) or scouring agents of
any type be used.
û Remove fingerprints using a slightly damp
cloth or a mild cleaning agent.
û Never spray cleaning agents or other liq-
uids directly onto the display. Instead
dampen a cloth and carefully wipe the dis-
play clean.
û If faults occur, do not open the PCM equip-
ment yourself under any circumstances.
Always have defective devices repaired by
a qualified specialist workshop. We recom-
mend that this work be performed by a Por-
>>>
sche partner, as Porsche partners have
trained workshop personnel as well as the
necessary parts and tools.
