Practical hints What to do if ... Problem Possible cause/consequence The yellow ABS indicator lamp comes on while the engine is running. The ABS is temporarily not available. The ESP® and the BAS are also unavailable. The system's self-diagnosis may not be completed yet. The brake system is still functioning normally but without the systems specified above. Suggested solution Drive a short distance with added caution at a vehicle speed of above 12 mph (20 km/h). When the ABS indicator lamp goes out, the ABS, the ESP®, and the BAS are available again.
