(1) Where fault on the part of the injured person contributed to the occurrence of the damage, liability in damages as well as the extent of compensation to be provided depend on the circumstances, in particular on the extent to which the damage was caused mainly by one or the other party.
(2) This also applies if the fault of the injured person is limited to failing to draw the attention of the obligor to the danger of unusually extensive damage, where the obligor neither was aware of the danger nor ought to have been aware of it, or to failing to avert or mitigate the damage. The provision of section 278 applies accordingly.
