Porsche 928 1980 Owner's Manual page 36

Electric sliding roof
(optional equipment)
The roof can be opened and closed, fully or
partially, by depressing the respective sym-
bol on the rocker switch in the center console
in front of the gearshift lever.
The mechanism has a built-in safety feature.
Should the moving roof encounter an ob-
stacle, it will stop automatically to avoid
possible injury.
Manual operation
If the electric drive mechanism fails, the roof
can be operated manually. The crank handle
provided for this purpose is in the tool kit.
Remove the cover from the electric drive
mechanism at the rear of the headliner by
pulling it down and disengaging the spring
catch.
Remove screw and washer on bottom of
drive mechanism. Keep screw and washer
within easy reach.
Install handle in slot of drive mechanism and
tighten thumb screw.
Close the roof, remove the handle and re-
install washer and screw. Replace the cover.
Do not depress the rocker switch but let your
Porsche dealer correct the fault.
