The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
G WARNING
If the ABS malfunctions, the wheels may lock during hard braking.
This limits the steerability of the vehicle when braking and may
increase the braking distance. If ABS is deactivated due to a
malfunction, BAS and ESP ®
