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

WARNING
The brake system continues to function normally, but without the functions lis-
ted above. The wheels could therefore lock if you brake hard, for example.
The steerability and braking characteristics may be severely affected. The brak-
ing 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 defective, there is also a possibility that other systems,
such as the navigation system or the automatic transmission, will not be availa-
ble.
