If the ABS warning lights light up on the instrument
panel and on the on-board computer while the
engine is running, the ABS has switched off
because of a fault.
In this case, the braking system will operate
without lock prevention , as in vehicles without
ABS.
f Adapt your driving style to the changed
braking behaviour.
The ABS must be checked by your Porsche
partner in order to prevent the occurrence of
further faults with unpredictable conse-
quences.
f Consult a qualified specialist workshop. We
recommend a Porsche partner for this work as
they have trained workshop personnel and the
necessary parts and tools.
The ABS control unit is adjusted for the approved
tyre dimensions. The use of tyres with non-
approved dimensions can lead to different wheel
speeds, causing the ABS to switch off.
