The red ABS warning lamp is lit while the engine is running.
The ABS (Anti-lock Braking System) is malfunctioning.
An additional warning tone indicates that EBD (electronic brake force distribution) is malfunctioning.
Other driving and driving safety systems may also be malfunctioning.
G WARNING
The brake system continues to function normally, but without the functions listed above. The front and rear wheels could therefore lock if you brake hard, for exam-
ple.
The steerability and braking characteristics may be severely affected. The braking
distance may increase in an emergency braking situation.
If ESP ®
is not operational, ESP ®
is unable to stabilise the vehicle.
There is an increased risk of skidding and/or accident.
X Observe the additional display messages on the multifunction display.
