Problem
Possible causes/consequences and P Solutions
%
The yellow ABS warning
lamp is lit while the
engine is running. ABS (Anti-lock Braking System) is deactivated due to a malfunc-
tion. Therefore, BAS (Brake Assist), COLLISION PREVENTION
ASSIST PLUS, ESP ®
(Electronic Stability Program), the HOLD func-
tion and hill start assist are also deactivated, for example.
ATTENTION ASSIST is deactivated.
G WARNING
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 affec-
ted. 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. X
Observe the additional display messages in the multifunction
display. X
Drive on carefully. X
Visit a qualified specialist workshop immediately.
If the ABS control unit is faulty, there is also a possibility that other
systems, such as the navigation system or the automatic trans-
mission, will not be available.Warning and indicator lamps in the instrument cluster 261
