Indicator and warning lamps in the instrument cluster
Problem
Possible cause/consequence Suggested solutions
-
The yellow ABS warning
lamp comes on while the
engine is running.
G
Risk of accident
ABS has been deactivated due to
a malfunction. Therefore, Brake
Assist, ESP
®
and PRE-SAFE
®
are,
for example, also deactivated.
The brake system continues to
function normally, but without
electronic support. The wheels
could therefore lock if you brake
hard, for example.
X
Drive on carefully.
X
Observe the additional messages in the multi-function display
(
Y
page 255).
X
Visit a qualified specialist workshop as soon as possible.
