Issue Description

If a 6-point belt is used on the race track in conjunction with the Porsche sports bucket seat, the unfastened 3-point belt can prevent the side airbag from unfolding in the event of an accident.
In the separate Driver's Manual for the optional 6point belt, a reference is therefore made to remove
the 3-point belt in this case.

What should Porsche Centers do?

On vehicles where the campaign is open, please arrange for the Owner's Manual Supplement to be ordered and supplied to customers during the next workshop visit.
Please note that owners with a valid mailing address
have already been sent this supplement with the attached letter via mail and the campaign was then closed. There are only a small number of vehicles where
the campaign is still open, which corresponds to customers that PCNA was unable to reach by mail. For
these vehicles, the supplement WKD95100B2125 can
be ordered via PPL for $0.01 and the campaign closed.
As of the time of this posting (1/9/26), the remedy
is immediately available.

TI

is to supply the customer with the supplement if the
campaign is open in PCSS.
