G WARNING
Repeatedly switching on the seat heating can
cause the seat cushion and backrest pads to
become very hot. The health of persons with
limited temperature sensitivity or a limited
ability to react to excessively high tempera-
tures may be affected or they may even suffer
burn-like injuries. There is a risk of injury.

The system automatically switches down
