If any fault occurs in the TC/ABS or ESP system, the indicator lamp TCS/ESP OFF is lit via the P-Bus. The warning lamp is also lit when the system is disconnected manually, which can be done at speeds lower than 60 km/h (37.5 mph) by pressing the TCS/ESP button. The system can be connected by pressing the TCS/ESP button at any speed, whereupon the TCS/ESP OFF indicator lamp goes off again.

When the ignition is turned on, the lamp comes on; if there is no fault, the lamp goes off again after 3-5 seconds.
