lamp comes on while the
engine is running. G
Risk of accident
ABS has been deactivated due to
a malfunction. Therefore, Brake
Assist, ESP ®
and PRE-SAFE ®
are,
for example, also deactivated.
The brake system continues to
function normally, but without
electronic support. The wheels
could therefore lock if you brake
hard, for example. X

Therefore, the following systems
are, for example, also deactiva-
ted: Brake Assist, ESP ®
