-
The yellow ABS warning
lamp comes on while the
engine is running. G
Risk of accident
ABS (Anti-lock Brake System) is
deactivated due to a fault. There-
fore, ESP ®

Program), BAS (Brake Assist), the
steering assistant STEER CON-
TROL, the hill start assist and the
tyre pressure loss warning sys-
tem are also deactivated.
The brake system continues to
function normally, but without
electronic support. The wheels
could therefore lock if you brake
hard.
If the ABS control unit is faulty,
other systems may also not be
available: e.g. Parktronic sys-
tem*, the navigation system* or
the Autotronic*. X
Drive on carefully.
X Observe the additional messages in the multi-function display
