WARNING
Repeatedly setting the seat heating to level
3 may result in excessive seat temperatures.
The health of passengers that have limited
temperature sensitivity or a limited ability to
react to excessively high temperatures may
be affected or they may even suffer burn-like
injuries. Therefore, do not use seat heating
level 3 repeatedly.
The three red indicator lamps in the button indicate the heating level you have selected.
If the battery voltage is too
low, the seat
heating may switch off.
