In addition, the 00E5,00BBand0025 warning lamps light up in the
instrument cluster.
Possible causes are:
R Self-diagnosis is not yet complete
R The on-board voltage may be insufficient
G WARNING
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 affected. 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.
X Carefully drive a suitable distance, making slight steering move-
ments at a speed above 12 mph (20 km/h).
If the display message disappears, the functions mentioned above

other sources of electromagnetic radiation
R the system is outside the operating temperature range
R the on-board voltage is too low
