Problem Possible cause/consequence Suggested solutions
-
Theyellow ABS warning

engine is running. G
Risk of accident
ABS has been deactivated due to
a malfunction. ESP ®
, BAS and the
tyre pressure monitor* are there-
fore also deactivated.
The brake system continues to
function normally, but without
electronic support. Therefore,
the wheels could lock if you brake
hard.
If the ABS control unit is faulty,
there is also a possibility of mal-
functions in other systems, such
as the ultrasonic reversing aid ®
,
the navigation system ®
or the
automatic transmission. X
Drive on carefully.
X Observe the additional messages in the multi-function display
(Y page 194).
X Visit a qualified specialist workshop as soon as possible. Practical advice
