Possible causes are:
RSelf-diagnosis is not yet complete.
RThe on-board voltage may be insufficient.
GWARNING
The braking performance of the electric motor using recuperative
braking may be either reduced or not effective. If you do not make
an additional effort to apply the brake yourself, the braking effect
may not be sufficient. If necessary, counteract the reduced regen-
erative braking effect by applying the brake yourself.
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
The steerability and braking characteristics may be severely affec-
ted. The braking 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.
XCarefully drive a short distance on a suitable stretch of road,
making slight steering movements at a speed above 12 mph
(20 km/ h).
If the display message disappears, the functions mentioned
above are available again.
If the multifunction display still shows the display message:
