The yellow ABS warning
lamp is lit while the
engine is running.
ABS (Anti-lock Braking System) is deactivated due to a
malfunction. BAS (Brake Assist), BAS PLUS, ESP ® (Electronic
Stability Program), PRE-SAFE ® , PRE-SAFE ® Brake, the HOLD
function and hill start assist are therefore also deactivated, for
example.
ATTENTION ASSIST is deactivated.

The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
The steerability and braking characteristics may be severely
affected. The braking distance in an emergency braking situation
can increase.
If ESP
® is not operational, ESP ® is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
