If the instrument cluster has failed or malfunctioned, you may not recognize function restric-
tions in systems relevant to safety. The operating safety of your vehicle may be impaired.
There is a risk of an accident.

The on-board computer only shows messages or warnings from certain systems in the instru-
ment cluster display. You should therefore make sure your vehicle is operating safely at all
times. If the operating safety of your vehicle is impaired, stop the vehicle as soon as possible,
paying attention to road and traffic conditions. Then consult a qualified specialist workshop. 194
