Brake assist systems Driving
●
If the control lamp does not go out, or
comes on while driving, it means that the
ABS is not working properly. The vehicle can
only be stopped using normal braking (with-
out ABS). In this case the protective ABS
function will not be available. Go to a special-
ised workshop as soon as possible.
